3 Simple Habits to Improve Your Critical Thinking

• Helen Lee Bouygues

But simple doesn’t mean easy.

Too many business leaders are simply not reasoning through pressing issues, and it’s hurting their organizations.  The good news is that critical thinking is a learned behavior. There are three simple things you can do to train yourself to become a more effective critical thinker: question assumptions, reason through logic, and diversify your thought and perspectives. They may sound obvious, but deliberately cultivating these three key habits of mind go a long way in helping you become better at clear and robust reasoning.

A few years ago, a CEO assured me that his company was the market leader. “Clients will not leave for competitors,” he added. “It costs too much for them to switch.” Within weeks, the manufacturing giant Procter & Gamble elected not to renew its contract with the firm. The CEO was shocked — but he shouldn’t have been.

How to think effectively: Six stages of critical thinking

Credit: Elder / Paul

• Researchers propose six levels of critical thinkers: Unreflective thinkers, Challenged thinkers, Beginning thinkers, Practicing thinkers, Advanced thinkers, and Master thinkers.
• The framework comes from educational psychologists Linda Elder and Richard Paul.
• Teaching critical thinking skills is a crucial challenge in our times.

The coronavirus has not only decimated our populations, its spread has also attacked the very nature of truth and stoked inherent tensions between many different groups of people, both at local and international levels. Spawning widespread conspiracy theories and obfuscation by governments, the virus has also been a vivid demonstration of the need for teaching critical thinking skills necessary to survive in the 21st century. The stage theory of critical thinking development, devised by psychologists Linda Elder and Richard Paul , can help us gauge the sophistication of our current mental approaches and provides a roadmap to the thinking of others.

The researchers identified six predictable levels of critical thinkers, from ones lower in depth and effort to the advanced mind-masters, who are always steps ahead.

As the scientists write , moving up on this pyramid of thinking “is dependent upon a necessary level of commitment on the part of an individual to develop as a critical thinker.” Using your mind more effectively is not automatic and “is unlikely to take place “subconsciously.” In other words – you have to put in the work and keep doing it, or you’ll lose the faculty.

Here’s how the stages of intellectual development break down:

Unreflective thinker

These are people who don’t reflect about thinking and the effect it has on their lives. As such, they form opinions and make decisions based on prejudices and misconceptions while their thinking doesn’t improve.

Unreflective thinkers lack crucial skills that would allow them to parse their thought processes. They also do not apply standards like accuracy, relevance, precision, and logic in a consistent fashion.

How many such people are out there? You probably can guess based on social media comments. As Elder and Paul write , “it is perfectly possible for students to graduate from high school, or even college, and still be largely unreflective thinkers.”

Challenged thinker

This next level up thinker has awareness of the importance of thinking on their existence and knows that deficiencies in thinking can bring about major issues. As the psychologists explain, to solve a problem, you must first admit you have one.

People at this intellectual stage begin to understand that “high quality thinking requires deliberate reflective thinking about thinking”, and can acknowledge that their own mental processes might have many flaws. They might not be able to identify all the flaws, however.

A challenged thinker may have a sense that solid thinking involves navigating assumptions, inferences, and points of view, but only on an initial level. They may also be able to spot some instances of their own self-deception. The true difficulty for thinkers of this category is in not “believing that their thinking is better than it actually is, making it more difficult to recognize the problems inherent in poor thinking,” explain the researchers.

Thinkers at this level can go beyond the nascent intellectual humility and actively look to take control of their thinking across areas of their lives. They know that their own thinking can have blind spots and other problems and take steps to address those, but in a limited capacity.

Beginning thinker

Beginning thinkers place more value in reason, becoming self-aware in their thoughts. They may also be able to start looking at the concepts and biases underlying their ideas. Additionally, such thinkers develop higher internal standards of clarity, accuracy and logic, realizing that their ego plays a key role in their decisions.

Another big aspect that differentiates this stronger thinker – some ability to take criticism of their mental approach, even though they still have work to do and might lack clear enough solutions to the issues they spot.

Practicing thinker

This more experienced kind of thinker not only appreciates their own deficiencies, but has skills to deal with them. A thinker of this level will practice better thinking habits and will analyze their mental processes with regularity.

While they might be able to express their mind’s strengths and weaknesses, as a negative, practicing thinkers might still not have a systematic way of gaining insight into their thoughts and can fall prey to egocentric and self-deceptive reasoning.

How do you get to this stage? An important trait to gain, say the psychologists, is “intellectual perseverance.” This quality can provide “the impetus for developing a realistic plan for systematic practice (with a view to taking greater command of one’s thinking).”

“We must teach in such a way that students come to understand the power in knowing that whenever humans reason, they have no choice but to use certain predictable structures of thought: that thinking is inevitably driven by the questions, that we seek answers to questions for some purpose, that to answer questions, we need information, that to use information we must interpret it (i.e., by making inferences), and that our inferences, in turn, are based on assumptions, and have implications, all of which involves ideas or concepts within some point of view,” explain Elder and Paul.

One doesn’t typically get to this stage until college and beyond, estimate the scientists. This higher-level thinker would have strong habits that would allow them to analyze their thinking with insight about different areas of life. They would be fair-minded and able to spot the prejudicial aspects in the points of view of others and their own understanding.

While they’d have a good handle on the role of their ego in the idea flow, such thinkers might still not be able to grasp all the influences that affect their mentality.

Advanced thinker

The advanced thinker is at ease with self-critique and does so systematically, looking to improve. Among key traits required for this level are “intellectual insight” to develop new thought habits, “ intellectual integrity” to “recognize areas of inconsistency and contradiction in one’s life,” intellectual empathy ” to put oneself in the place of others in order to genuinely understand them, and the “ intellectual courage” to confront ideas and beliefs they don’t necessarily believe in and have negative emotions towards.

Master thinker

This is the super-thinker, the one who is totally in control of how they process information and make decisions. Such people constantly seek to improve their thought skills, and through experience “regularly raise their thinking to the level of conscious realization.”

A master thinker achieves great insights into deep mental levels, strongly committed to being fair and gaining control over their own egocentrism.

Such a high-level thinker also exhibits superior practical knowledge and insight, always re-examining their assumptions for weaknesses, logic, and biases.

And, of course, a master thinker wouldn’t get upset with being intellectually confronted and spends a considerable amount of time analyzing their own responses.

“Why is this so important? Precisely because the human mind, left to its own, pursues that which is immediately easy, that which is comfortable, and that which serves its selfish interests. At the same time, it naturally resists that which is difficult to understand, that which involves complexity, that which requires entering the thinking and predicaments of others,” write the researchers.

So how do you become a master thinker? The psychologists think most students will never get there. But a lifetime of practicing the best intellectual traits can get you to that point when “people of good sense seek out master thinkers, for they recognize and value the ability of master thinkers to think through complex issues with judgment and insight.”

The significance of critical thinking in our daily lives, especially in these confusing times, so rife with quick and often-misleading information, cannot be overstated. The decisions we make today can truly be life and death.

How to build your critical thinking skills in 7 steps (with examples)

Critical thinking is, well, critical. By building these skills, you improve your ability to analyze information and come to the best decision possible. In this article, we cover the basics of critical thinking, as well as the seven steps you can use to implement the full critical thinking process.

Critical thinking comes from asking the right questions to come to the best conclusion possible. Strong critical thinkers analyze information from a variety of viewpoints in order to identify the best course of action.

Don’t worry if you don’t think you have strong critical thinking abilities. In this article, we’ll help you build a foundation for critical thinking so you can absorb, analyze, and make informed decisions. 

What is critical thinking? 

Critical thinking is the ability to collect and analyze information to come to a conclusion. Being able to think critically is important in virtually every industry and applicable across a wide range of positions. That’s because critical thinking isn’t subject-specific—rather, it’s your ability to parse through information, data, statistics, and other details in order to identify a satisfactory solution. 

Definitions of critical thinking

Various scholars have provided definitions of critical thinking, each emphasizing different aspects of this complex cognitive process:

Michael Scriven , an American philosopher, defines critical thinking as "the intellectually disciplined process of actively and skillfully conceptualizing, applying, analyzing, synthesizing, and/or evaluating information gathered from, or generated by, observation, experience, reflection, reasoning, or communication as a guide to belief and action."

Robert Ennis , professor emeritus at the University of Illinois, describes critical thinking as "reasonable, reflective thinking focused on deciding what to believe or do."

Diane Halpern , a cognitive psychologist and former president of the American Psychological Association, defines it as "the use of cognitive skills or strategies that increase the probability of a desirable outcome."

Top 8 critical thinking skills

Critical thinking is essential for success in everyday life, higher education, and professional settings. The handbook "Foundation for Critical Thinking" defines it as a process of conceptualization, analysis, synthesis, and evaluation of information.

In no particular order, here are eight key critical thinking abilities that can help you excel in any situation:

1. Analytical thinking

Analytical thinking involves evaluating data from multiple sources in order to come to the best conclusions. Analytical thinking allows people to reject cognitive biases and strive to gather and analyze intricate subject matter while solving complex problems. Analytical thinkers who thrive at critical thinking can:

Identify patterns and trends in the data

Break down complex issues into manageable components

Recognize cause-and-effect relationships

Evaluate the strength of arguments and evidence

Example: A data analyst breaks down complex sales figures to identify trends and patterns that inform the company's marketing strategy.

2. Open-mindedness

Open-mindedness is the willingness to consider new ideas, arguments, and information without prejudice. This critical thinking skill helps you analyze and process information to come to an unbiased conclusion. Part of the critical thinking process is letting your personal biases go, taking information at face value and coming to a conclusion based on multiple points of view .

Open-minded critical thinkers demonstrate:

Willingness to consider alternative viewpoints

Ability to suspend judgment until sufficient evidence is gathered

Receptiveness to constructive criticism and feedback

Flexibility in updating beliefs based on new information

Example: During a product development meeting, a team leader actively considers unconventional ideas from junior members, leading to an innovative solution.

3. Problem-solving

Effective problem solving is a cornerstone of critical thinking. It requires the ability to identify issues, generate possible solutions, evaluate alternatives, and implement the best course of action. This critical thinking skill is particularly valuable in fields like project management and entrepreneurship.

Key aspects of problem-solving include:

Clearly defining the problem

Gathering relevant information

Brainstorming potential solutions

Evaluating the pros and cons of each option

Implementing and monitoring the chosen solution

Reflecting on the outcome and adjusting as necessary

Example: A high school principal uses problem-solving skills to address declining student engagement by surveying learners, consulting with higher education experts, and implementing a new curriculum that balances academic rigor with practical, real-world applications.

4. Reasoned judgment

Reasoned judgment is a key component of higher order thinking that involves making thoughtful decisions based on logical analysis of evidence and thorough consideration of alternatives. This critical thinking skill is important in both academic and professional settings. Key aspects reasoned judgment include:

Objectively gathering and analyzing information

Evaluating the credibility and relevance of evidence

Considering multiple perspectives before drawing conclusions

Making decisions based on logical inference and sound reasoning

Example: A high school science teacher uses reasoned judgment to design an experiment, carefully observing and analyzing results before drawing conclusions about the hypothesis.

5. Reflective thinking

Reflective thinking is the process of analyzing one's own thought processes, actions, and outcomes to gain deeper understanding and improve future performance. Good critical thinking requires analyzing and synthesizing information to form a coherent understanding of a problem. It's an essential critical thinking skill for continuous learning and improvement.

Key aspects of reflective thinking include:

Critically examining one's own assumptions and cognitive biases

Considering diverse viewpoints and perspectives

Synthesizing information from various experiences and sources

Applying insights to improve future decision-making and actions

Continuously evaluating and adjusting one's thinking processes

Example: A community organizer reflects on the outcomes of a recent public event, considering what worked well and what could be improved for future initiatives.

6. Communication

Strong communication skills help critical thinkers articulate ideas clearly and persuasively. Communication in the workplace is crucial for effective teamwork, leadership, and knowledge dissemination. Key aspects of communication in critical thinking include:

Clearly expressing complex ideas

Active listening and comprehension

Adapting communication styles to different audiences

Constructing and delivering persuasive arguments

Example: A manager effectively explains a new company policy to her team, addressing their concerns and ensuring everyone understands its implications.

7. Research

Critical thinkers with strong research skills gather, evaluate, and synthesize information from various sources of information. This is particularly important in academic settings and in professional fields that require continuous learning. Effective research involves:

Identifying reliable and relevant sources of information

Evaluating the credibility and bias of sources

Synthesizing information from multiple sources

Recognizing gaps in existing knowledge

Example: A journalist verifies information from multiple credible sources before publishing an article on a controversial topic.

8. Decision-making

Effective decision making is the culmination of various critical thinking skills that allow an individual to draw logical conclusions and generalizations. It involves weighing options, considering consequences, and choosing the best course of action. Key aspects of decision-making include:

Defining clear criteria for evaluation

Gathering and analyzing relevant information

Considering short-term and long-term consequences

Managing uncertainty and risk

Balancing logic and intuition

Example: A homeowner weighs the costs, benefits, and long-term implications before deciding to invest in solar panels for their house.

7 steps to improve critical thinking

Critical thinking is a skill that you can build by following these seven steps. The seven steps to critical thinking help you ensure you’re approaching a problem from the right angle, considering every alternative, and coming to an unbiased conclusion.

First things first: When to use the 7 step critical thinking process

There’s a lot that goes into the full critical thinking process, and not every decision needs to be this thought out. Sometimes, it’s enough to put aside bias and approach a process logically. In other, more complex cases, the best way to identify the ideal outcome is to go through the entire critical thinking process. 

The seven-step critical thinking process is useful for complex decisions in areas you are less familiar with. Alternatively, the seven critical thinking steps can help you look at a problem you’re familiar with from a different angle, without any bias. 

If you need to make a less complex decision, consider another problem solving strategy instead. Decision matrices are a great way to identify the best option between different choices. Check out our article on 7 steps to creating a decision matrix .

1. Identify the problem or question

Before you put those critical thinking skills to work, you first need to identify the problem you’re solving. This step includes taking a look at the problem from a few different perspectives and asking questions like: 

What’s happening? 

Why is this happening? 

What assumptions am I making? 

At first glance, how do I think we can solve this problem? 

A big part of developing your critical thinking skills is learning how to come to unbiased conclusions. In order to do that, you first need to acknowledge the biases that you currently have. Does someone on your team think they know the answer? Are you making assumptions that aren’t necessarily true? Identifying these details helps you later on in the process. 

2. Gather relevant information

At this point, you likely have a general idea of the problem—but in order to come up with the best solution, you need to dig deeper. 

During the research process, collect information relating to the problem, including data, statistics, historical project information, team input, and more. Make sure you gather information from a variety of sources, especially if those sources go against your personal ideas about what the problem is or how to solve it.

Gathering varied information is essential for your ability to apply the critical thinking process. If you don’t get enough information, your ability to make a final decision will be skewed. Remember that critical thinking is about helping you identify the objective best conclusion. You aren’t going with your gut—you’re doing research to find the best option

3. Analyze and evaluate data

Just as it’s important to gather a variety of information, it is also important to determine how relevant the different information sources are. After all, just because there is data doesn’t mean it’s relevant. 

Once you’ve gathered all of the information, sift through the noise and identify what information is relevant and what information isn’t. Synthesizing all of this information and establishing significance helps you weigh different data sources and come to the best conclusion later on in the critical thinking process. 

To determine data relevance, ask yourself:

How reliable is this information? 

How significant is this information? 

Is this information outdated? Is it specialized in a specific field? 

4. Consider alternative points of view

One of the most useful parts of the critical thinking process is coming to a decision without bias. In order to do so, you need to take a step back from the process and challenge the assumptions you’re making. 

We all have bias—and that isn’t necessarily a bad thing. Unconscious biases (also known as cognitive biases) often serve as mental shortcuts to simplify problem solving and aid decision making. But even when biases aren’t inherently bad, you must be aware of your biases in order to put them aside when necessary. 

Before coming to a solution, ask yourself:

Am I making any assumptions about this information? 

Are there additional variables I haven’t considered? 

Have I evaluated the information from every perspective? 

Are there any viewpoints I missed?

5. Draw logical conclusions

Finally, you’re ready to come to a conclusion. To identify the best solution, draw connections between causes and effects. Use the facts you’ve gathered to evaluate the most objective conclusion. 

Keep in mind that there may be more than one solution. Often, the problems you’re facing are complex and intricate. The critical thinking process doesn’t necessarily lead to a cut-and-dry solution—instead, the process helps you understand the different variables at play so you can make an informed decision. 

6. Develop and communication solutions

Communication is a key skill for critical thinkers. It isn’t enough to think for yourself—you also need to share your conclusion with other project stakeholders. If there are multiple solutions, present them all. There may be a case where you implement one solution, then test to see if it works before implementing another solution. 

This process of communicating and sharing ideas is key in promoting critical thinking within a team or organization. By encouraging open dialogue and collaborative problem-solving, you create an environment that fosters the development of critical thinking skills in others.

7. Reflect and learn from the process

The seven-step critical thinking process yields a result—and you then need to put that solution into place. After you’ve implemented your decision, evaluate whether or not it was effective. Did it solve the initial problem? What lessons—whether positive or negative—can you learn from this experience to improve your critical thinking for next time? 

By engaging in this metacognitive reflective thinking process, you're essentially teaching critical thinking to yourself, refining your methodology with each iteration. This reflective practice is fundamental in developing a more robust and adaptable approach to problem-solving.

Depending on how your team shares information, consider documenting lessons learned in a central source of truth. That way, team members that are making similar or related decisions in the future can understand why you made the decision you made and what the outcome was.

Example of critical thinking in the workplace

Imagine you work in user experience design (UX). Your team is focused on pricing and packaging and ensuring customers have a clear understanding of the different services your company offers. Here’s how to apply the critical thinking process in the workplace in seven steps: 

Step 1: Start by identifying the problem

Your current pricing page isn’t performing as well as you want. You’ve heard from customers that your services aren’t clear, and that the page doesn’t answer the questions they have. This page is really important for your company, since it’s where your customers sign up for your service. You and your team have a few theories about why your current page isn’t performing well, but you decide to apply the critical thinking process to ensure you come to the best decision for the page. 

Gather information about how the problem started

Part of identifying the problem includes understanding how the problem started. The pricing and packaging page is important—so when your team initially designed the page, they certainly put a lot of thought into it. Before you begin researching how to improve the page, ask yourself: 

Why did you design the pricing page the way you did? 

Which stakeholders need to be involved in the decision making process? 

Where are users getting stuck on the page?

Are any features currently working?

Step 2: Then gather information and research

In addition to understanding the history of the pricing and packaging page, it’s important to understand what works well. Part of this research means taking a look at what your competitor’s pricing pages look like. 

Ask yourself: 

How have our competitors set up their pricing pages?

Are there any pricing page best practices? 

How does color, positioning, and animation impact navigation? 

Are there any standard page layouts customers expect to see? 

Step 3: Organize and analyze information

You’ve gathered all of the information you need—now you need to organize and analyze it. What trends, if any, are you noticing? Is there any particularly relevant or important information that you have to consider? 

Step 4: Consider alternative viewpoints to reduce bias

In the case of critical thinking, it’s important to address and set bias aside as much as possible. Ask yourself: 

Is there anything I’m missing? 

Have I connected with the right stakeholders? 

Are there any other viewpoints I should consider? 

Step 5: Determine the most logical solution for your team

You now have all of the information you need to design the best pricing page. Depending on the complexity of the design, you may want to design a few options to present to a small group of customers or A/B test on the live website.

Step 6: Communicate your solution to stakeholders

Critical thinking can help you in every element of your life, but in the workplace, you must also involve key project stakeholders . Stakeholders help you determine next steps, like whether you’ll A/B test the page first. Depending on the complexity of the issue, consider hosting a meeting or sharing a status report to get everyone on the same page. 

Step 7: Reflect on the results

No process is complete without evaluating the results. Once the new page has been live for some time, evaluate whether it did better than the previous page. What worked? What didn’t? This also helps you make better critical decisions later on.

Tools and techniques to improve critical thinking skills

As the importance of critical thinking continues to grow in academic and professional settings, numerous tools and resources have been developed to help individuals enhance their critical thinking skills. Here are some notable contributions from experts and institutions in the field:

Mind mapping for better analysis

Mind mapping is a visual technique that helps organize and structure information. It's particularly useful for synthesizing complex ideas and identifying connections between different concepts. The benefits of mind mapping include:

Enhancing creativity by encouraging non-linear thinking

Improving memory and retention of information

Facilitating brainstorming and idea generation

Providing a clear overview of complex topics

To create a mind map:

Start with a central idea or concept.

Branch out with related sub topics or ideas.

Use colors, symbols, and images to enhance visual appeal and memorability.

Draw connections between related ideas across different branches.

Mind mapping can be particularly effective in project planning , content creation, and studying complex subjects.

The Socratic Method for deeper understanding

The Socratic Method, named after the ancient Greek philosopher Socrates, involves asking probing questions to stimulate critical thinking and illuminate ideas. This technique is widely used in higher education to teach critical thinking. Key aspects of the Socratic Method include:

Asking open-ended questions that encourage deeper reflection

Challenging assumptions and preconceived notions

Exploring the implications and consequences of ideas

Fostering intellectual curiosity and continuous inquiry

The Socratic Method can be applied in various settings:

In education, to encourage students to think deeply about subject matter

In business, it is important to challenge team members to consider multiple points of view.

In personal development, to examine one's own beliefs and decisions

Example: A high school teacher might use the Socratic Method to guide students through a complex ethical dilemma, asking questions like "What principles are at stake here?" and "How might this decision affect different stakeholders?"

SWOT analysis for comprehensive evaluation

SWOT (Strengths, Weaknesses, Opportunities, Threats) analysis is a strategic planning tool that can be applied to critical thinking. It helps in evaluating situations from multiple angles, promoting a more thorough understanding of complex issues. The components of SWOT analysis are:

Strengths: internal positive attributes or assets

Weaknesses: internal negative attributes or limitations

Opportunities: External factors that could be beneficial

Threats: External factors that could be harmful

To conduct a SWOT analysis:

Clearly define the subject of analysis (e.g., a project, organization, or decision).

Brainstorm and list items for each category.

Analyze the interactions between different factors.

Use the analysis to inform strategy or decision-making.

Example: A startup might use SWOT analysis to evaluate its position before seeking investment, identifying its innovative technology as a strength, limited capital as a weakness, growing market demand as an opportunity, and established competitors as a threat.

What is Critical Thinking?

Critical thinking is the ability to think clearly and rationally, understanding the logical connection between ideas.  Critical thinking has been the subject of much debate and thought since the time of early Greek philosophers such as Plato and Socrates and has continued to be a subject of discussion into the modern age, for example the ability to recognise fake news .

Critical thinking might be described as the ability to engage in reflective and independent thinking.

In essence, critical thinking requires you to use your ability to reason. It is about being an active learner rather than a passive recipient of information.

Critical thinkers rigorously question ideas and assumptions rather than accepting them at face value. They will always seek to determine whether the ideas, arguments and findings represent the entire picture and are open to finding that they do not.

Critical thinkers will identify, analyse and solve problems systematically rather than by intuition or instinct.

Someone with critical thinking skills can:

Understand the links between ideas.

Determine the importance and relevance of arguments and ideas.

Recognise, build and appraise arguments.

Identify inconsistencies and errors in reasoning.

Approach problems in a consistent and systematic way.

Reflect on the justification of their own assumptions, beliefs and values.

Critical thinking is thinking about things in certain ways so as to arrive at the best possible solution in the circumstances that the thinker is aware of. In more everyday language, it is a way of thinking about whatever is presently occupying your mind so that you come to the best possible conclusion.

Critical Thinking is:

A way of thinking about particular things at a particular time; it is not the accumulation of facts and knowledge or something that you can learn once and then use in that form forever, such as the nine times table you learn and use in school.

The Skills We Need for Critical Thinking

The skills that we need in order to be able to think critically are varied and include observation, analysis, interpretation, reflection, evaluation, inference, explanation, problem solving, and decision making.

Specifically we need to be able to:

Think about a topic or issue in an objective and critical way.

Identify the different arguments there are in relation to a particular issue.

Evaluate a point of view to determine how strong or valid it is.

Recognise any weaknesses or negative points that there are in the evidence or argument.

Notice what implications there might be behind a statement or argument.

Provide structured reasoning and support for an argument that we wish to make.

The Critical Thinking Process

You should be aware that none of us think critically all the time.

Sometimes we think in almost any way but critically, for example when our self-control is affected by anger, grief or joy or when we are feeling just plain ‘bloody minded’.

On the other hand, the good news is that, since our critical thinking ability varies according to our current mindset, most of the time we can learn to improve our critical thinking ability by developing certain routine activities and applying them to all problems that present themselves.

Once you understand the theory of critical thinking, improving your critical thinking skills takes persistence and practice.

Try this simple exercise to help you to start thinking critically.

Think of something that someone has recently told you. Then ask yourself the following questions:

Who said it?

Someone you know? Someone in a position of authority or power? Does it matter who told you this?

What did they say?

Did they give facts or opinions? Did they provide all the facts? Did they leave anything out?

Where did they say it?

Was it in public or in private? Did other people have a chance to respond an provide an alternative account?

When did they say it?

Was it before, during or after an important event? Is timing important?

Why did they say it?

Did they explain the reasoning behind their opinion? Were they trying to make someone look good or bad?

How did they say it?

Were they happy or sad, angry or indifferent? Did they write it or say it? Could you understand what was said?

What are you Aiming to Achieve?

One of the most important aspects of critical thinking is to decide what you are aiming to achieve and then make a decision based on a range of possibilities.

Once you have clarified that aim for yourself you should use it as the starting point in all future situations requiring thought and, possibly, further decision making. Where needed, make your workmates, family or those around you aware of your intention to pursue this goal. You must then discipline yourself to keep on track until changing circumstances mean you have to revisit the start of the decision making process.

However, there are things that get in the way of simple decision making. We all carry with us a range of likes and dislikes, learnt behaviours and personal preferences developed throughout our lives; they are the hallmarks of being human. A major contribution to ensuring we think critically is to be aware of these personal characteristics, preferences and biases and make allowance for them when considering possible next steps, whether they are at the pre-action consideration stage or as part of a rethink caused by unexpected or unforeseen impediments to continued progress.

The more clearly we are aware of ourselves, our strengths and weaknesses, the more likely our critical thinking will be productive.

The Benefit of Foresight

Perhaps the most important element of thinking critically is foresight.

Almost all decisions we make and implement don’t prove disastrous if we find reasons to abandon them. However, our decision making will be infinitely better and more likely to lead to success if, when we reach a tentative conclusion, we pause and consider the impact on the people and activities around us.

The elements needing consideration are generally numerous and varied. In many cases, consideration of one element from a different perspective will reveal potential dangers in pursuing our decision.

For instance, moving a business activity to a new location may improve potential output considerably but it may also lead to the loss of skilled workers if the distance moved is too great. Which of these is the more important consideration? Is there some way of lessening the conflict?

These are the sort of problems that may arise from incomplete critical thinking, a demonstration perhaps of the critical importance of good critical thinking.

In Summary:

Critical thinking is aimed at achieving the best possible outcomes in any situation. In order to achieve this it must involve gathering and evaluating information from as many different sources possible.

Critical thinking requires a clear, often uncomfortable, assessment of your personal strengths, weaknesses and preferences and their possible impact on decisions you may make.

Critical thinking requires the development and use of foresight as far as this is possible. As Doris Day sang, “the future’s not ours to see”.

Implementing the decisions made arising from critical thinking must take into account an assessment of possible outcomes and ways of avoiding potentially negative outcomes, or at least lessening their impact.

• Critical thinking involves reviewing the results of the application of decisions made and implementing change where possible.

It might be thought that we are overextending our demands on critical thinking in expecting that it can help to construct focused meaning rather than examining the information given and the knowledge we have acquired to see if we can, if necessary, construct a meaning that will be acceptable and useful.

After all, almost no information we have available to us, either externally or internally, carries any guarantee of its life or appropriateness.  Neat step-by-step instructions may provide some sort of trellis on which our basic understanding of critical thinking can blossom but it doesn’t and cannot provide any assurance of certainty, utility or longevity.

10 Ways to Develop Your Critical Thinking Skills

Valerie David

Lifestyle and Career Expert

Many a TV and movie hero would have you believe that all the best decisions are made with a ‘gut feeling’. Unlike that onscreen police detective whose hunches solve major crimes and get him the key to the city, however, most of us would likely be jobless if we operated this way.

While intuition can be a valuable skill in the workplace , most employers would prefer you excel in critical thinking and problem solving . So, what makes someone a critical thinker, exactly? It’s the ability to look at issues objectively and effectively, without letting bias or emotions cloud your judgement.

It’s not an easy task, but critical thinking improves your communication with others, helps you solve problems in the best interests of everyone involved, and allows you to see a clearer path to success and advancement in your career . The good news is you can begin right away, so read on to learn how to develop your critical thinking skills.

1. Take Time to Evaluate Your Decision Making

The first step in developing your critical thinking skills is to set aside time to evaluate your daily choices and decisions. In the same way a coach looks at a recording of a game to identify his team’s strengths and weaknesses, use this exercise to identify your successful actions that day, as well as the scenarios that didn’t turn out as well as you hoped.

Ask yourself a series of questions about those actions. What was your motivation? Did you achieve your goals? Did you do something contrary to your own belief system? Take the extra time to really think about your answers. You might want to keep a journal of these self-evaluations to help you spot patterns in your thinking and decision making .

2. Avoid Egocentrism

Most people evaluate issues or disagreements with the default view that they themselves are correct. Being a more critical thinker requires us to contemplate the possibility that we may be wrong or are acting in our own self-interest rather than the good of others or of the company we work for.

Two prominent authors and instructors in the field of critical thinking development , Richard Paul and Linda Elder, say that feelings of irritation and resentment during the workday can actually be signs of egocentric thinking. Considering how a ‘rational’ person (think Mr Spock from Star Trek ) might have reacted to the same situation can help you understand how your own emotions or bias affected your actions.

Those same emotions can also affect your interpretation of others’ actions. Taking arguments personally and feeling attacked by someone else’s opinion can cloud your judgement. Try to view their statements as an attempt to solve a problem or improve conditions, and not a strike against your self-worth.

3. Be an Active Listener

When someone is speaking to us, we are often more focused on what we’re going to say in response than in carefully listening to everything they’re sharing. We miss important details and don’t take the time to consider or fully comprehend their point of view.

Next time you converse with someone, actively listen to their story, their argument and even their criticisms. Cataloguing all this information without immediately reacting to it helps you improve your critical thinking skills and understand your colleagues better.

Active listening also gives you the time to experience and empathise with their situation, which is helpful for facilitating teamwork and resolving conflicts at work .

4. Analyse the Information

Gathering data is only the first step in the process of becoming a critical thinker. Achieving a goal or resolving an argument requires analysing all that information. This once again means asking a lot of questions.

• What is the source of the information?
• Are there gaps in logic in someone’s argument?
• Are they using emotion rather than facts to sway your opinion?
• Is there any evidence to support their point of view or yours?

In a work environment, you have to carefully dissect each side of an issue, and then consider how any decision would affect your colleagues as well as the company’s bottom line.

5. Gather Research

Another important step in improving your critical thinking skills is to accept that you don’t know everything. Many articles have been written about common misconceptions about a whole range of subjects, so you should always take the time to verify any ‘facts’ you base your decisions or arguments on.

The trick of researching is to find reliable information. Always check the source. Is it a well-respected journal or news outlet? Is the author an educated and experienced expert? Can you verify the same information from multiple sites or authorities?

Critical thinkers also consider an author’s agenda, anything from a political affiliation to a product to sell.

6. Develop Your Curiosity

Think about the last time you conversed with someone who asked you a lot of detailed questions and made you uncomfortable. We often spend time with friends, sharing opinions without challenge, and it can be startling when someone actually calls us out on those opinions. Forced to explain our thought process, we may realise our argument wasn’t that sound after all.

If you want to develop your critical thinking, it’s time to be that questioning person. When someone shares an idea or judgement, don’t just accept it and move on to the next thing. Indulge your curiosity and ask some open-ended questions to get more details, and further explore the issue.

7. Approach Arguments with Compassion

In the age of social media discourse, which can escalate rapidly from name-calling to harassment to even death threats, a peaceful approach can be daunting. The first step is to look for the logic in an opponent’s argument. Focus on the critical thinking skills you apply to your own decisions and examine their motivations, evidence and reasoning.

Making an immediate effort to understand the opposing point of view can help keep you from becoming defensive and escalating the disagreement. The compassionate approach won’t necessarily lead to complete harmony, but an open mind allows you to examine all the information and, hopefully, find common ground.

The ability to understand others’ emotions and skilfully negotiate with them is considered a valuable skill to potential employers . Becoming a critical thinker in highly charged situations needn't be wasted on Twitter flame wars; it’s extremely useful in making a sale to a difficult client, keeping an unhappy customer on board or even convincing your boss to use your idea for a new product line instead of theirs.

8. Examine Decisions in Multiple Environments

When facing a difficult decision, everyone has heard the advice to ‘sleep on it’. This is sound advice. One of the main pillars of critical thinking is to remove emotion from the equation. If you’ve just had an argument with a colleague, you’ve been reprimanded by your boss for a mistake or even if you’ve just had an all-around bad day at work , it’s best to hold off on important decisions until you feel calmer and more rational.

Even when things are peaceful, take the time to look at a problem from multiple angles. Change your environment, mood, and who you interact with to help spark creative thinking and get you to a solution you might not have considered at the start.

9. Assign Yourself a Problem to Work On

Any skill you want to master requires practice. Applying critical thinking in your daily interactions will help you improve, but a specific task is also useful. Think of an issue in your career and spend any free moments during the day, like during your commute or on your lunch break, breaking that problem down into pieces you can analyse.

The goal during this analysis is to identify actionable elements. What can you do right now? What moves can you make over time to reach the perfect solution? How can you work around the issues that you can’t control? Continue to analyse the results after you act and adapt your strategies as you move forward.

Critical thinking and problem solving have always been useful at work, but employers will increasingly look for these skills as jobs become more complex and challenging due to ever-evolving technology and globalisation. Continue to assign yourself problems to tackle; even minor issues will help you keep your critical skills sharp.

10. Talk to a More Diverse Group of People

You can develop critical thinking skills with a lot of self-reflection, research and study, but staying locked in your own bubble can lead right back to egocentrism. Seek out people with different backgrounds, experiences and opinions to simply learn from them or to engage in some lively debate.

One of the most positive aspects of the internet is that it allows us to make these connections more easily. Aside from forums, group chats and social media, consider guesting on a podcast in your field of expertise. The more casual format can lead to some lively discussions and will force you to apply all your critical thinking skills on the fly. You can approach podcasters directly or try out services like Podcast Guests to connect you with interested hosts.

The key to improving your critical thinking skills is to constantly ask questions and seek the truth about everyone’s motives and actions, including your own. You won’t always be able to keep emotions out of an argument but practising these critical thinking strategies will help you find your way through difficult and complex situations to the best possible outcome.

Can you think of a time when these strategies helped you solve a problem at work? Do you have your own techniques for perfecting critical thinking? Let us know in the comments section below.

What is critical thinking?

5 characteristics of critical thinking, what are critical thinking skills, and why are they important, 6 key critical thinking skills, critical thinking example in real-life, 13 ways to start thinking critically.

Whether you’re aiming to improve your performance at work or simply trying to live a more fulfilling life , you’ll need a variety of hard and soft skills to move the needle. Some skills come naturally to some people, while others need to develop them actively.

One of these skills is critical thinking. But critical thinking itself is made up of several types of skills that contribute to solving problems more effectively.

Let’s explore the different types of critical thinking skills and how you can start improving them to level up your career.

Critical thinking is the ability to analyze facts objectively and form a judgment. It is a form of emotional intelligence .

Someone with critical thinking skills can think clearly and rationally when the situation demands it. It allows them to perform problem-solving and decision-making more effectively. 

As a result, you can look further than what you see at face value. You’re able to analyze what you see from a situation and gain some insight that goes further than what’s obvious to anyone from the outside.

Critical thinking also requires being able to understand the logical connection between two or more ideas or concepts. For example, a team working on a company’s pricing strategy needs to think critically about several concepts. 

Both the marketing and sales teams must work together. They need to analyze how to maximize sales. But they need to do so while also meeting profit goals. It’s important to understand the logical connection between sales strategy and marketing logistics. It’s the only way to get a good outcome.

Critical thinking is different from creative thinking . Creative thinking is the ability to generate brand new, innovative ideas. On the other hand, critical thinking requires you to carefully and logically analyze what information is given to you. Both are important to maximize results in any given situation.

What defines critical thinking? How does it affect the decision-making process? Here are five characteristics that make up the ability to think critically.

1. Dispositions

Critical thinkers have specific traits that allow them to think the way they do. Some people are predisposed to these traits, while others need to develop them actively.

Some of these dispositions include:

• Open-mindedness
• Respecting evidence and reasoning
• Being able to consider different perspectives and points of view: in other words, having cognitive flexibility
• Not being stuck in one position
• Clarity and precision

2. Argument

Good critical thinkers need to make solid arguments. 

An argument is making a statement aided by supporting evidence. It’s important to use well thought-out arguments when you’re in a constructive conflict . When analyzing a situation critically, you’ll need to make several arguments in your own mind to come to a judgment. 

3. Reasoning

In addition to arguments, critical thinking also requires inferring conclusions. From the facts and arguments presented to you, you need to use reasoning skills to come to a logical conclusion. 

This conclusion will determine the best course of action to take.

4. Criteria

Critical thinking is sometimes a matter of discerning truth from fiction. Not all facts presented to you may have the same level of truth. Certain conditions need to be met for something to be considered believable, and a critical thinker needs to be able to understand that.

5. Metacognition

Metacognition is the ability to think about your own thinking. Critical thinkers should be able to analyze their thoughts so that they can judge whether or not they’ve thought everything through. This helps them come up with better hypotheses.

The critical thinking skills definition is: soft skills that help you in the critical thinking process. Developing these skills can improve your ability to think critically.

Critical thinking skills are considered one of many durable skills in the workplace . Many of these are soft skills that are also useful in other situations.

According to research by America Succeeds, critical thinking is in the top five most requested durable skills in job postings. Those top five durable skills get requested 2.6x more often than the top five hard skills. This goes to show that soft skills like critical thinking skills are in demand in the workplace.

Critical thinking skills are important for several reasons. These include helping you work independently and solve problems . Not all positions require ongoing critical thinking. But, those skills definitely matter to anyone who wants to uplevel their career. And even the most easygoing positions require at least some level of critical thinking skills.

For example, working as an accountant can be straightforward in most cases. But it may require critical thinking skills. For instance, what if certain expenses aren’t easily distributed in simple categories? Without critical thinking skills, an accountant will struggle to work independently and solve problems on their own.

Critical thinking abilities also matter in everyday life. Having a foundation for critical thinking can help you analyze several possible solutions for problems that pop up in the home. It can also help you:

• Analyze different viewpoints
• Come up with the best solution for complex problems
• Become a better learner

The key critical thinking skills are identifying biases, inference, research, identification, curiosity, and judging relevance.

Let’s explore these six critical thinking skills you should learn and why they’re so important to the critical thinking process.

1. Identifying biases

This critical thinking skill is necessary for metacognition, which is the fifth characteristic of critical thinking. It involves knowing when others have a cognitive bias and when you have one yourself.

Biases can influence how someone understands the facts presented to them. But when you’re aware of those biases, you can question yourself on those biases and consider other points of view.

Identifying biases is especially important for people who make hiring decisions. That’s because biases against groups of minorities can lead to inequalities in the workplace when not identified. 

For example, imagine a hiring manager comparing two resumes. Their gut feeling could guide them to discount one of the resumes due to a bias against the opposite gender. But let’s say this hiring manager realizes they have this bias. They can then question themselves on whether or not this bias is influencing their judgment. 

2. Inference

Inference is the ability to draw conclusions based on the information you have. Without inference, it can be difficult to take action once you’ve analyzed the facts presented to you. Processing information is key to coming up with a reasoned judgment.

For example, let’s go back to the accountant struggling to assign the correct category to a business expense. They can analyze other similar situations and infer the most logical category based on that information.

3. Research

Before you analyze facts and infer a conclusion, you need to find out what those facts are. Researching skills allow you to discover facts and figures to make an argument.

Not all situations will have the required information available to you. Researching skills are necessary to dig into a situation and gather the information you need to think critically.

Some situations don’t require further research. For example, a first responder who arrives on the scene of an automobile accident won’t perform further research. They’ll have to analyze what they see in front of them and decide which injuries are the most urgent to care for. 

On the other hand, someone performing a market analysis will need to research competitors and gather information before coming up with an opinion. 

4. Identification

Identification is different from inference and research. It involves being able to identify a problem but also what’s influencing that problem.

In short, identification is necessary for someone to realize that they need to think critically about something. Without proper identification skills, it will be difficult for someone to know when it’s time to analyze a situation. 

For example, let’s say you’re entering numbers in a spreadsheet. The numbers aren’t coming out as they usually do. Without identification skills, you could easily keep going without realizing there’s an issue. But when you identify what’s going on, you can see that something is broken in the spreadsheet’s formula.

Only once you identify the fact that the formula is broken can you start analyzing what’s going on to solve the issue.

5. Curiosity

Don’t be afraid to question everything and explore what you’re curious about. That’s because intellectual curiosity is a valuable skill, especially when it comes to critical thinking.

One way to practice curiosity is to adopt a beginner’s mindset . When you come into every situation with the mindset of a beginner, you’re able to keep an open mind. You’ll be able to perceive things you may not have noticed when keeping your mind closed.

6. Judging relevance

Not all information is equally pertinent. In order to make a critical judgment, it’s important to be able to judge the relevance of the information you have.

Take, for instance, basic online researching skills. You have access to a plethora of information on virtually every topic imaginable. But performing online research requires you to constantly judge the relevance of what you see. 

Without judging relevance, you’d spend too much time on details that don’t matter as much for the final desired outcome. But when you’re able to discern what’s most pertinent, you can give that information more weight as you’re thinking critically.

So what would critical thinking skills look like in a real-life situation?

Let’s imagine you’re working in software quality assurance (QA) as a team lead. But every time your team needs to enter bug regression, everyone gets bottlenecked because you must manually populate the spreadsheet used for the regression. While you do this task, your team cannot be productive without you.

This process happens once a week and easily wastes half an hour for each team member.

First, you must identify what’s going on. The team gets bottlenecked because only you, as the team lead, can access the information required to fill in the regression spreadsheet.

Next, you can research information. You can inquire to higher-ups about the reason why only you have access to this information. You can also speak to other teams about what potential solutions they’ve come up with to solve this problem.

Once you’ve done your research, it’s time to analyze the information and judge relevance. Some teams have solutions that don’t apply to you, so that information isn’t relevant anymore. 

Figure out if there are any personal biases before you analyze your information. 

For example, it’s possible that you don’t get along with one of the other team leads. As a result, you could discount the information they’ve given you. But by identifying this bias, you can look past your personal opinion of this person and see how valuable their solution is.

Based on what you’ve analyzed, it’s time to brainstorm and come up with a solution. You realize that creating a simple, automated script will save your team’s time. And it will do so without consuming too many resources from the engineering department.

Next, present your solution to your manager. Explain how you came to this conclusion. 

Now, let’s say your spreadsheet automation solution is approved. It’s important to go back and analyze what happens after implementing the solution. But only do this once the spreadsheet has been in place for long enough to gather plenty of information. 

Here’s an example. You could realize that the solution did solve the bottleneck. But, the script also slows down the spreadsheet and makes it difficult to work with. This would require you to go back to the drawing board and start the process all over again.

Critical Thinking Is All About “Connecting the Dots”

Why memory is the missing piece in teaching critical thinking..

Updated July 23, 2024 | Reviewed by Monica Vilhauer

• Critical thinking requires us to simultaneously analyze and interpret different pieces of information.
• To effectively interpret information, one must first be able to remember it.
• With technology reducing our memory skills, we must work on strengthening them.

I have a couple of questions for my regular (or semi-regular) readers, touching on a topic I’ve discussed many times on this blog. When it comes to power, persuasion , and influence, why is critical thinking so crucial? Alternatively, what are some common traps and pitfalls for those who prioritize critical thinking? It's not necessary that you go in to great detail—just any vague or general information that comes to mind will do.

Great! Regardless of whether you recalled anything specific, the key is you made the effort to remember something. Like many questions I pose here, the real purpose is to illustrate a point. If you aim to be influential and persuasive—i.e., successful—in both work and life, you must be proficient in critical thinking. To achieve this proficiency, you need to cultivate and exercise your memory , a skill that is increasingly at risk in a technology-saturated age.

Remembering Is the Foundation of Knowing

Learning and remembering something are often discussed as if they are two separate processes, but they are inextricably linked . Consider this: Everything you know now is something you once had to learn, from basic facts to complex knowledge and skills. Retaining this information as actual knowledge, rather than fleeting stimuli, depends entirely on memory. Without memory, there is no knowledge. Consequently, there can be no critical thinking, as it relies on prior knowledge, which in turn relies on memory.

Students sometimes tell me that they want to learn how to be good critical thinkers but complain about having to “memorize stuff.” On these occasions I will often say, in a playfully teasing manner, “What I hear you saying is that you're bothered by having to remember stuff.” This usually helps them see how silly and unreasonable it is to complain about memorizing information, as there isn’t a single course in existence that doesn’t require remembering something . The ability to remember is at the core of critical thinking, and I often use the simple visual demonstration that follows to illustrate this point.

Collecting Dots and Connecting the Dots

Benjamin Bloom, an educational psychologist, developed a model known as the “Taxonomy of Learning.” Originally intended for educational psychology, this model also highlights why memory is the foundation of critical thinking—or any kind of thinking at all.

Humans are creatures of interpretation, constantly processing the information we perceive. This ability has made us the scientists, inventors, and artists that we are today. To interpret information, however, we must first remember it—not all information, obviously, as that’s impossible. Thanks to technology (which we’ll get to momentarily) we have vast amounts of information potentially at our fingertips. But how do you know what information to look up in a given situation? To know where to start and avoid endlessly searching irrelevant data, you need to remember enough of the right kind of information.

Think of a crime movie where an investigator, while reviewing evidence, suddenly has an epiphany and rushes off to confirm their hunch. These scenes illustrate that while the investigator needs more information, they remember enough to know what to search for.

Here’s a visual demonstration I use in class to help my students understand. Imagine you have pieces of information represented as five dots:

Now let’s say that any coherent shape or picture you can draw using these dots is an interpretation of the information. When examined together, what might these five dots mean? Here’s one way to connect the dots.

What does this shape represent? Many people will quickly say it’s a house, a common and reasonable interpretation. But not everyone sees it as a house. Some might say it’s the home plate used in baseball. Even when people connect the dots (i.e., interpret a cluster of information) the same way using the same lines, they don’t necessarily interpret the picture the same way. The situation becomes more complex when people connect the dots differently, creating a completely different shape or picture.

Now, having connected the dots differently, instead of a house, we have a star. Or at least some would consider it a star; others might say it’s an occult or magic symbol—these are all very different interpretations. This shows that with the same pieces of information, people can “connect the dots” differently, and even when they connect them the same way, they see different things.

Now what happens when additional information is added or an alleged “missing dot” is perceived by others?

With just one additional dot, what could have previously been interpreted as a 5-pointed star can now be reasonably interpreted as the Star of David.

Finally, sometimes the additional information can lead to a completely different shape or image, resulting in a “eureka” moment of insight. What previously appeared as different types of stars now looks like a circle.

I use this classroom demonstration to illustrate how people can interpret the same objective information in highly subjective ways, creating different narratives for themselves and others. This is a crucial point to remember when aiming to influence or persuade others—i.e., the need to see things from their perspective. Additionally, this activity powerfully underscores the importance of “collecting dots”—that is, the importance of remembering crucial bits of information. Without enough such dots, you lack the basic information needed to form meaningful ideas. Without meaningful ideas, you can’t think critically, influence, or persuade. It’s as straightforward as that.

Memory in the Age of Omnipresent Technology

Why is it so crucial to recognize that memory is foundational to critical thinking, power, influence, and persuasion? Partly because this fact isn’t widely acknowledged—and it needs to be. Additionally, we live in an era where memory is under unprecedented assault. While technology allows us to achieve remarkable feats unimaginable to previous generations, it comes at a cost. One such cost is “digital-induced amnesia,” where our memory capabilities atrophy due to information overload and technology taking over many of the cognitive tasks we used to perform ourselves.

Memory doesn’t exist in isolation. It’s closely tied to traits like the ability to focus and pay attention . If you’re not paying attention, you can’t absorb the information that you want or need to remember. Unfortunately, technology also impacts our ability to focus , and this doesn’t even touch on the dramatic ways AI ’s explosive development might undermine our thinking skills .

This article won’t delve into specifics on improving focus and memory in an age of tech ubiquity. Fortunately, resources from Psychology Today can help with that. My goal here is to convince you why memory is so vital for anyone who wishes to be a critical thinker and a persuasive, influential person. Now you know. Whether you’ll remember or not...only time will tell.

What Is Critical Thinking? | Definition & Examples

Published on May 30, 2022 by Eoghan Ryan . Revised on May 31, 2023.

Critical thinking is the ability to effectively analyze information and form a judgment .

To think critically, you must be aware of your own biases and assumptions when encountering information, and apply consistent standards when evaluating sources .

Critical thinking skills help you to:

• Identify credible sources
• Evaluate and respond to arguments
• Assess alternative viewpoints
• Test hypotheses against relevant criteria

Why is critical thinking important, critical thinking examples, how to think critically, other interesting articles, frequently asked questions about critical thinking.

Critical thinking is important for making judgments about sources of information and forming your own arguments. It emphasizes a rational, objective, and self-aware approach that can help you to identify credible sources and strengthen your conclusions.

Critical thinking is important in all disciplines and throughout all stages of the research process . The types of evidence used in the sciences and in the humanities may differ, but critical thinking skills are relevant to both.

In academic writing , critical thinking can help you to determine whether a source:

• Is free from research bias
• Provides evidence to support its research findings
• Considers alternative viewpoints

Outside of academia, critical thinking goes hand in hand with information literacy to help you form opinions rationally and engage independently and critically with popular media.

Critical thinking can help you to identify reliable sources of information that you can cite in your research paper . It can also guide your own research methods and inform your own arguments.

Outside of academia, critical thinking can help you to be aware of both your own and others’ biases and assumptions.

Academic examples

However, when you compare the findings of the study with other current research, you determine that the results seem improbable. You analyze the paper again, consulting the sources it cites.

You notice that the research was funded by the pharmaceutical company that created the treatment. Because of this, you view its results skeptically and determine that more independent research is necessary to confirm or refute them. Example: Poor critical thinking in an academic context You’re researching a paper on the impact wireless technology has had on developing countries that previously did not have large-scale communications infrastructure. You read an article that seems to confirm your hypothesis: the impact is mainly positive. Rather than evaluating the research methodology, you accept the findings uncritically.

Nonacademic examples

However, you decide to compare this review article with consumer reviews on a different site. You find that these reviews are not as positive. Some customers have had problems installing the alarm, and some have noted that it activates for no apparent reason.

You revisit the original review article. You notice that the words “sponsored content” appear in small print under the article title. Based on this, you conclude that the review is advertising and is therefore not an unbiased source. Example: Poor critical thinking in a nonacademic context You support a candidate in an upcoming election. You visit an online news site affiliated with their political party and read an article that criticizes their opponent. The article claims that the opponent is inexperienced in politics. You accept this without evidence, because it fits your preconceptions about the opponent.

There is no single way to think critically. How you engage with information will depend on the type of source you’re using and the information you need.

However, you can engage with sources in a systematic and critical way by asking certain questions when you encounter information. Like the CRAAP test , these questions focus on the currency , relevance , authority , accuracy , and purpose of a source of information.

When encountering information, ask:

• Who is the author? Are they an expert in their field?
• What do they say? Is their argument clear? Can you summarize it?
• When did they say this? Is the source current?
• Where is the information published? Is it an academic article? Is it peer-reviewed ?
• Why did the author publish it? What is their motivation?
• How do they make their argument? Is it backed up by evidence? Does it rely on opinion, speculation, or appeals to emotion ? Do they address alternative arguments?

Critical thinking also involves being aware of your own biases, not only those of others. When you make an argument or draw your own conclusions, you can ask similar questions about your own writing:

• Am I only considering evidence that supports my preconceptions?
• Is my argument expressed clearly and backed up with credible sources?
• Would I be convinced by this argument coming from someone else?

Critical thinking refers to the ability to evaluate information and to be aware of biases or assumptions, including your own.

Like information literacy , it involves evaluating arguments, identifying and solving problems in an objective and systematic way, and clearly communicating your ideas.

Critical thinking skills include the ability to:

You can assess information and arguments critically by asking certain questions about the source. You can use the CRAAP test , focusing on the currency , relevance , authority , accuracy , and purpose of a source of information.

Ask questions such as:

• Who is the author? Are they an expert?
• How do they make their argument? Is it backed up by evidence?

A credible source should pass the CRAAP test  and follow these guidelines:

• The information should be up to date and current.
• The author and publication should be a trusted authority on the subject you are researching.
• The sources the author cited should be easy to find, clear, and unbiased.
• For a web source, the URL and layout should signify that it is trustworthy.

Information literacy refers to a broad range of skills, including the ability to find, evaluate, and use sources of information effectively.

Being information literate means that you:

• Know how to find credible sources
• Use relevant sources to inform your research
• Understand what constitutes plagiarism
• Know how to cite your sources correctly

Confirmation bias is the tendency to search, interpret, and recall information in a way that aligns with our pre-existing values, opinions, or beliefs. It refers to the ability to recollect information best when it amplifies what we already believe. Relatedly, we tend to forget information that contradicts our opinions.

Although selective recall is a component of confirmation bias, it should not be confused with recall bias.

On the other hand, recall bias refers to the differences in the ability between study participants to recall past events when self-reporting is used. This difference in accuracy or completeness of recollection is not related to beliefs or opinions. Rather, recall bias relates to other factors, such as the length of the recall period, age, and the characteristics of the disease under investigation.

Critical Thinking is the art of using reason to analyze ideas and dig deeper to get to our true potential. Critical thinking isn't about thinking more or thinking harder; it's about thinking better . Honing your critical thinking skills can open up a lifetime of intellectual curiosity. But the journey isn't all rosy. Critical thinking requires a lot of discipline. Staying on track takes a combination of steady growth, motivation, and the ability to take an honest look at yourself, even in the face of some uncomfortable facts.

Honing Your Questioning Skills

• What does it mean to question assumptions? Einstein questioned the assumption that Newtonian laws of motion could accurately describe the world. [2] X Research source He developed an entirely new framework for looking at the world by re describing what he thought had happened, starting from scratch.
• We can question assumptions in a similar way. Why do we feel the need to eat in the morning, even when we're not hungry? Why do we assume that we'll fail when we haven't even tried?
• What other assumptions are we taking for granted that might crumble upon further examination?

• Get in the habit of using your instinct to investigate questionable pieces of information. If your gut isn't satisfied with an explanation, ask the person to elaborate. If you don't question a fact, read about it or test it yourself. Soon enough, you'll build up a pretty good sense of what deserves more research and what you've determined to be true in your own judgment.

• How can we take meaningful steps to fight global poverty ?
• How do we dismantle production of nuclear weapons worldwide?

Adjusting Your Perspective

• Jeff Bezos, CEO of Amazon.com, famously understood the benefits of thinking several steps ahead. He tired Wired Magazine in 2011: "If everything you do needs to work on a three-year time horizon, then you’re competing against a lot of people. But if you’re willing to invest on a seven-year time horizon, you’re now competing against a fraction of those people, because very few companies are willing to do that." When the Kindle first hit stores in 2007 it was more than three years in development, at a time when e-readers were on nobody's radar. [7] X Research source

• Solve a problem a day. Spend a little bit of time figuring out a problem and then try to solve it. [11] X Research source The problem could be a theoretical or a personal one.
• Find the time to exercise consistently. 30 minutes of aerobic exercise — as little as a walk around the neighborhood — can help improve brain function.
• Eat the right kinds of foods. Avocados, blueberries, wild salmon, nuts and seeds, as well as brown rice play an instrumental role in keeping your brain healthy. [12] X Research source

• Use libraries and the Internet, to find out information on the topic you're critiquing. An uninformed critique is sometimes worse than one merely executed badly. Thanks Helpful 2 Not Helpful 0

• Give criticism in a non-offensive way, as people can get defensive if something they pride themselves on gets attacked. Therefore do not antagonize a hard-core abortion supporter by giving a heated anti-abortion speech. It will only make him go on an offensive to defend his beliefs, totally ignore your arguments, and strengthen his resolve to support abortion. Prefacing criticism with praise usually works well.

About This Article

You can improve your critical thinking skills by questioning information that you hear instead of taking it at face-value. Double-check facts that you hear, regardless of whether you get your information from other people, on TV, from a newspaper or online. Reading great books is another way to improve critical thinking, as books encourage you to think more deeply and independently about subjects. If there’s anything you don’t understand, ask someone who’s knowledgeable about the subject to explain it to you. With practice, you'll become more and more comfortable with critical thinking!

Critical Thinking

Critical thinking is a widely accepted educational goal. Its definition is contested, but the competing definitions can be understood as differing conceptions of the same basic concept: careful thinking directed to a goal. Conceptions differ with respect to the scope of such thinking, the type of goal, the criteria and norms for thinking carefully, and the thinking components on which they focus. Its adoption as an educational goal has been recommended on the basis of respect for students’ autonomy and preparing students for success in life and for democratic citizenship. “Critical thinkers” have the dispositions and abilities that lead them to think critically when appropriate. The abilities can be identified directly; the dispositions indirectly, by considering what factors contribute to or impede exercise of the abilities. Standardized tests have been developed to assess the degree to which a person possesses such dispositions and abilities. Educational intervention has been shown experimentally to improve them, particularly when it includes dialogue, anchored instruction, and mentoring. Controversies have arisen over the generalizability of critical thinking across domains, over alleged bias in critical thinking theories and instruction, and over the relationship of critical thinking to other types of thinking.

Use of the term ‘critical thinking’ to describe an educational goal goes back to the American philosopher John Dewey (1910), who more commonly called it ‘reflective thinking’. He defined it as

active, persistent and careful consideration of any belief or supposed form of knowledge in the light of the grounds that support it, and the further conclusions to which it tends. (Dewey 1910: 6; 1933: 9)

and identified a habit of such consideration with a scientific attitude of mind. His lengthy quotations of Francis Bacon, John Locke, and John Stuart Mill indicate that he was not the first person to propose development of a scientific attitude of mind as an educational goal.

In the 1930s, many of the schools that participated in the Eight-Year Study of the Progressive Education Association (Aikin 1942) adopted critical thinking as an educational goal, for whose achievement the study’s Evaluation Staff developed tests (Smith, Tyler, & Evaluation Staff 1942). Glaser (1941) showed experimentally that it was possible to improve the critical thinking of high school students. Bloom’s influential taxonomy of cognitive educational objectives (Bloom et al. 1956) incorporated critical thinking abilities. Ennis (1962) proposed 12 aspects of critical thinking as a basis for research on the teaching and evaluation of critical thinking ability.

Since 1980, an annual international conference in California on critical thinking and educational reform has attracted tens of thousands of educators from all levels of education and from many parts of the world. Also since 1980, the state university system in California has required all undergraduate students to take a critical thinking course. Since 1983, the Association for Informal Logic and Critical Thinking has sponsored sessions in conjunction with the divisional meetings of the American Philosophical Association (APA). In 1987, the APA’s Committee on Pre-College Philosophy commissioned a consensus statement on critical thinking for purposes of educational assessment and instruction (Facione 1990a). Researchers have developed standardized tests of critical thinking abilities and dispositions; for details, see the Supplement on Assessment . Educational jurisdictions around the world now include critical thinking in guidelines for curriculum and assessment.

For details on this history, see the Supplement on History .

2. Examples and Non-Examples

Before considering the definition of critical thinking, it will be helpful to have in mind some examples of critical thinking, as well as some examples of kinds of thinking that would apparently not count as critical thinking.

Dewey (1910: 68–71; 1933: 91–94) takes as paradigms of reflective thinking three class papers of students in which they describe their thinking. The examples range from the everyday to the scientific.

Transit : “The other day, when I was down town on 16th Street, a clock caught my eye. I saw that the hands pointed to 12:20. This suggested that I had an engagement at 124th Street, at one o’clock. I reasoned that as it had taken me an hour to come down on a surface car, I should probably be twenty minutes late if I returned the same way. I might save twenty minutes by a subway express. But was there a station near? If not, I might lose more than twenty minutes in looking for one. Then I thought of the elevated, and I saw there was such a line within two blocks. But where was the station? If it were several blocks above or below the street I was on, I should lose time instead of gaining it. My mind went back to the subway express as quicker than the elevated; furthermore, I remembered that it went nearer than the elevated to the part of 124th Street I wished to reach, so that time would be saved at the end of the journey. I concluded in favor of the subway, and reached my destination by one o’clock.” (Dewey 1910: 68–69; 1933: 91–92)

Ferryboat : “Projecting nearly horizontally from the upper deck of the ferryboat on which I daily cross the river is a long white pole, having a gilded ball at its tip. It suggested a flagpole when I first saw it; its color, shape, and gilded ball agreed with this idea, and these reasons seemed to justify me in this belief. But soon difficulties presented themselves. The pole was nearly horizontal, an unusual position for a flagpole; in the next place, there was no pulley, ring, or cord by which to attach a flag; finally, there were elsewhere on the boat two vertical staffs from which flags were occasionally flown. It seemed probable that the pole was not there for flag-flying.

“I then tried to imagine all possible purposes of the pole, and to consider for which of these it was best suited: (a) Possibly it was an ornament. But as all the ferryboats and even the tugboats carried poles, this hypothesis was rejected. (b) Possibly it was the terminal of a wireless telegraph. But the same considerations made this improbable. Besides, the more natural place for such a terminal would be the highest part of the boat, on top of the pilot house. (c) Its purpose might be to point out the direction in which the boat is moving.

“In support of this conclusion, I discovered that the pole was lower than the pilot house, so that the steersman could easily see it. Moreover, the tip was enough higher than the base, so that, from the pilot’s position, it must appear to project far out in front of the boat. Moreover, the pilot being near the front of the boat, he would need some such guide as to its direction. Tugboats would also need poles for such a purpose. This hypothesis was so much more probable than the others that I accepted it. I formed the conclusion that the pole was set up for the purpose of showing the pilot the direction in which the boat pointed, to enable him to steer correctly.” (Dewey 1910: 69–70; 1933: 92–93)

Bubbles : “In washing tumblers in hot soapsuds and placing them mouth downward on a plate, bubbles appeared on the outside of the mouth of the tumblers and then went inside. Why? The presence of bubbles suggests air, which I note must come from inside the tumbler. I see that the soapy water on the plate prevents escape of the air save as it may be caught in bubbles. But why should air leave the tumbler? There was no substance entering to force it out. It must have expanded. It expands by increase of heat, or by decrease of pressure, or both. Could the air have become heated after the tumbler was taken from the hot suds? Clearly not the air that was already entangled in the water. If heated air was the cause, cold air must have entered in transferring the tumblers from the suds to the plate. I test to see if this supposition is true by taking several more tumblers out. Some I shake so as to make sure of entrapping cold air in them. Some I take out holding mouth downward in order to prevent cold air from entering. Bubbles appear on the outside of every one of the former and on none of the latter. I must be right in my inference. Air from the outside must have been expanded by the heat of the tumbler, which explains the appearance of the bubbles on the outside. But why do they then go inside? Cold contracts. The tumbler cooled and also the air inside it. Tension was removed, and hence bubbles appeared inside. To be sure of this, I test by placing a cup of ice on the tumbler while the bubbles are still forming outside. They soon reverse” (Dewey 1910: 70–71; 1933: 93–94).

Dewey (1910, 1933) sprinkles his book with other examples of critical thinking. We will refer to the following.

Weather : A man on a walk notices that it has suddenly become cool, thinks that it is probably going to rain, looks up and sees a dark cloud obscuring the sun, and quickens his steps (1910: 6–10; 1933: 9–13).

Disorder : A man finds his rooms on his return to them in disorder with his belongings thrown about, thinks at first of burglary as an explanation, then thinks of mischievous children as being an alternative explanation, then looks to see whether valuables are missing, and discovers that they are (1910: 82–83; 1933: 166–168).

Typhoid : A physician diagnosing a patient whose conspicuous symptoms suggest typhoid avoids drawing a conclusion until more data are gathered by questioning the patient and by making tests (1910: 85–86; 1933: 170).

Blur : A moving blur catches our eye in the distance, we ask ourselves whether it is a cloud of whirling dust or a tree moving its branches or a man signaling to us, we think of other traits that should be found on each of those possibilities, and we look and see if those traits are found (1910: 102, 108; 1933: 121, 133).

Suction pump : In thinking about the suction pump, the scientist first notes that it will draw water only to a maximum height of 33 feet at sea level and to a lesser maximum height at higher elevations, selects for attention the differing atmospheric pressure at these elevations, sets up experiments in which the air is removed from a vessel containing water (when suction no longer works) and in which the weight of air at various levels is calculated, compares the results of reasoning about the height to which a given weight of air will allow a suction pump to raise water with the observed maximum height at different elevations, and finally assimilates the suction pump to such apparently different phenomena as the siphon and the rising of a balloon (1910: 150–153; 1933: 195–198).

Diamond : A passenger in a car driving in a diamond lane reserved for vehicles with at least one passenger notices that the diamond marks on the pavement are far apart in some places and close together in others. Why? The driver suggests that the reason may be that the diamond marks are not needed where there is a solid double line separating the diamond lane from the adjoining lane, but are needed when there is a dotted single line permitting crossing into the diamond lane. Further observation confirms that the diamonds are close together when a dotted line separates the diamond lane from its neighbour, but otherwise far apart.

Rash : A woman suddenly develops a very itchy red rash on her throat and upper chest. She recently noticed a mark on the back of her right hand, but was not sure whether the mark was a rash or a scrape. She lies down in bed and thinks about what might be causing the rash and what to do about it. About two weeks before, she began taking blood pressure medication that contained a sulfa drug, and the pharmacist had warned her, in view of a previous allergic reaction to a medication containing a sulfa drug, to be on the alert for an allergic reaction; however, she had been taking the medication for two weeks with no such effect. The day before, she began using a new cream on her neck and upper chest; against the new cream as the cause was mark on the back of her hand, which had not been exposed to the cream. She began taking probiotics about a month before. She also recently started new eye drops, but she supposed that manufacturers of eye drops would be careful not to include allergy-causing components in the medication. The rash might be a heat rash, since she recently was sweating profusely from her upper body. Since she is about to go away on a short vacation, where she would not have access to her usual physician, she decides to keep taking the probiotics and using the new eye drops but to discontinue the blood pressure medication and to switch back to the old cream for her neck and upper chest.

Candidate : Although Dewey included no examples of thinking directed at appraising the arguments of others, such thinking has come to be considered a kind of critical thinking. We find an example of such thinking in the performance task on the Collegiate Learning Assessment (CLA+), which its sponsoring organization describes as

a performance-based assessment that provides a measure of an institution’s contribution to the development of critical-thinking and written communication skills of its students. (Council for Aid to Education 2017)

A sample task posted on its website requires the test-taker to write a report for public distribution evaluating a fictional candidate’s policy proposals and their supporting arguments, using supplied background documents, with a recommendation on whether to endorse the candidate.

Immediate acceptance of an idea that suggests itself as a solution to a problem (e.g., a possible explanation of an event or phenomenon, an action that seems likely to produce a desired result) is “uncritical thinking, the minimum of reflection” (Dewey 1910: 13). On-going suspension of judgment in the light of doubt about a possible solution is not critical thinking (Dewey 1910: 108). Critique driven by a dogmatically held political or religious ideology is not critical thinking; thus Paulo Freire (1968 [1970]) is using the term (e.g., at 1970: 71, 81, 100, 146) in a more politically freighted sense that includes not only reflection but also revolutionary action against oppression. Derivation of a conclusion from given data using an algorithm is not critical thinking.

What is critical thinking? There are many definitions. Ennis (2016) lists 14 philosophically oriented scholarly definitions and three dictionary definitions. Following Rawls (1971), who distinguished his conception of justice from a utilitarian conception but regarded them as rival conceptions of the same concept, Ennis maintains that the 17 definitions are different conceptions of the same concept. Rawls articulated the shared concept of justice as

a characteristic set of principles for assigning basic rights and duties and for determining… the proper distribution of the benefits and burdens of social cooperation. (Rawls 1971: 5)

Bailin et al. (1999b) claim that, if one considers what sorts of thinking an educator would take not to be critical thinking and what sorts to be critical thinking, one can conclude that educators typically understand critical thinking to have at least three features.

• It is done for the purpose of making up one’s mind about what to believe or do.
• The person engaging in the thinking is trying to fulfill standards of adequacy and accuracy appropriate to the thinking.
• The thinking fulfills the relevant standards to some threshold level.

One could sum up the core concept that involves these three features by saying that critical thinking is careful goal-directed thinking. This core concept seems to apply to all the examples of critical thinking described in the previous section. As for the non-examples, their exclusion depends on construing careful thinking as excluding jumping immediately to conclusions, suspending judgment no matter how strong the evidence, reasoning from an unquestioned ideological or religious perspective, and routinely using an algorithm to answer a question.

If the core of critical thinking is careful goal-directed thinking, conceptions of it can vary according to its presumed scope, its presumed goal, one’s criteria and threshold for being careful, and the thinking component on which one focuses. As to its scope, some conceptions (e.g., Dewey 1910, 1933) restrict it to constructive thinking on the basis of one’s own observations and experiments, others (e.g., Ennis 1962; Fisher & Scriven 1997; Johnson 1992) to appraisal of the products of such thinking. Ennis (1991) and Bailin et al. (1999b) take it to cover both construction and appraisal. As to its goal, some conceptions restrict it to forming a judgment (Dewey 1910, 1933; Lipman 1987; Facione 1990a). Others allow for actions as well as beliefs as the end point of a process of critical thinking (Ennis 1991; Bailin et al. 1999b). As to the criteria and threshold for being careful, definitions vary in the term used to indicate that critical thinking satisfies certain norms: “intellectually disciplined” (Scriven & Paul 1987), “reasonable” (Ennis 1991), “skillful” (Lipman 1987), “skilled” (Fisher & Scriven 1997), “careful” (Bailin & Battersby 2009). Some definitions specify these norms, referring variously to “consideration of any belief or supposed form of knowledge in the light of the grounds that support it and the further conclusions to which it tends” (Dewey 1910, 1933); “the methods of logical inquiry and reasoning” (Glaser 1941); “conceptualizing, applying, analyzing, synthesizing, and/or evaluating information gathered from, or generated by, observation, experience, reflection, reasoning, or communication” (Scriven & Paul 1987); the requirement that “it is sensitive to context, relies on criteria, and is self-correcting” (Lipman 1987); “evidential, conceptual, methodological, criteriological, or contextual considerations” (Facione 1990a); and “plus-minus considerations of the product in terms of appropriate standards (or criteria)” (Johnson 1992). Stanovich and Stanovich (2010) propose to ground the concept of critical thinking in the concept of rationality, which they understand as combining epistemic rationality (fitting one’s beliefs to the world) and instrumental rationality (optimizing goal fulfillment); a critical thinker, in their view, is someone with “a propensity to override suboptimal responses from the autonomous mind” (2010: 227). These variant specifications of norms for critical thinking are not necessarily incompatible with one another, and in any case presuppose the core notion of thinking carefully. As to the thinking component singled out, some definitions focus on suspension of judgment during the thinking (Dewey 1910; McPeck 1981), others on inquiry while judgment is suspended (Bailin & Battersby 2009, 2021), others on the resulting judgment (Facione 1990a), and still others on responsiveness to reasons (Siegel 1988). Kuhn (2019) takes critical thinking to be more a dialogic practice of advancing and responding to arguments than an individual ability.

In educational contexts, a definition of critical thinking is a “programmatic definition” (Scheffler 1960: 19). It expresses a practical program for achieving an educational goal. For this purpose, a one-sentence formulaic definition is much less useful than articulation of a critical thinking process, with criteria and standards for the kinds of thinking that the process may involve. The real educational goal is recognition, adoption and implementation by students of those criteria and standards. That adoption and implementation in turn consists in acquiring the knowledge, abilities and dispositions of a critical thinker.

Conceptions of critical thinking generally do not include moral integrity as part of the concept. Dewey, for example, took critical thinking to be the ultimate intellectual goal of education, but distinguished it from the development of social cooperation among school children, which he took to be the central moral goal. Ennis (1996, 2011) added to his previous list of critical thinking dispositions a group of dispositions to care about the dignity and worth of every person, which he described as a “correlative” (1996) disposition without which critical thinking would be less valuable and perhaps harmful. An educational program that aimed at developing critical thinking but not the correlative disposition to care about the dignity and worth of every person, he asserted, “would be deficient and perhaps dangerous” (Ennis 1996: 172).

Dewey thought that education for reflective thinking would be of value to both the individual and society; recognition in educational practice of the kinship to the scientific attitude of children’s native curiosity, fertile imagination and love of experimental inquiry “would make for individual happiness and the reduction of social waste” (Dewey 1910: iii). Schools participating in the Eight-Year Study took development of the habit of reflective thinking and skill in solving problems as a means to leading young people to understand, appreciate and live the democratic way of life characteristic of the United States (Aikin 1942: 17–18, 81). Harvey Siegel (1988: 55–61) has offered four considerations in support of adopting critical thinking as an educational ideal. (1) Respect for persons requires that schools and teachers honour students’ demands for reasons and explanations, deal with students honestly, and recognize the need to confront students’ independent judgment; these requirements concern the manner in which teachers treat students. (2) Education has the task of preparing children to be successful adults, a task that requires development of their self-sufficiency. (3) Education should initiate children into the rational traditions in such fields as history, science and mathematics. (4) Education should prepare children to become democratic citizens, which requires reasoned procedures and critical talents and attitudes. To supplement these considerations, Siegel (1988: 62–90) responds to two objections: the ideology objection that adoption of any educational ideal requires a prior ideological commitment and the indoctrination objection that cultivation of critical thinking cannot escape being a form of indoctrination.

Despite the diversity of our 11 examples, one can recognize a common pattern. Dewey analyzed it as consisting of five phases:

• suggestions , in which the mind leaps forward to a possible solution;
• an intellectualization of the difficulty or perplexity into a problem to be solved, a question for which the answer must be sought;
• the use of one suggestion after another as a leading idea, or hypothesis , to initiate and guide observation and other operations in collection of factual material;
• the mental elaboration of the idea or supposition as an idea or supposition ( reasoning , in the sense on which reasoning is a part, not the whole, of inference); and
• testing the hypothesis by overt or imaginative action. (Dewey 1933: 106–107; italics in original)

The process of reflective thinking consisting of these phases would be preceded by a perplexed, troubled or confused situation and followed by a cleared-up, unified, resolved situation (Dewey 1933: 106). The term ‘phases’ replaced the term ‘steps’ (Dewey 1910: 72), thus removing the earlier suggestion of an invariant sequence. Variants of the above analysis appeared in (Dewey 1916: 177) and (Dewey 1938: 101–119).

The variant formulations indicate the difficulty of giving a single logical analysis of such a varied process. The process of critical thinking may have a spiral pattern, with the problem being redefined in the light of obstacles to solving it as originally formulated. For example, the person in Transit might have concluded that getting to the appointment at the scheduled time was impossible and have reformulated the problem as that of rescheduling the appointment for a mutually convenient time. Further, defining a problem does not always follow after or lead immediately to an idea of a suggested solution. Nor should it do so, as Dewey himself recognized in describing the physician in Typhoid as avoiding any strong preference for this or that conclusion before getting further information (Dewey 1910: 85; 1933: 170). People with a hypothesis in mind, even one to which they have a very weak commitment, have a so-called “confirmation bias” (Nickerson 1998): they are likely to pay attention to evidence that confirms the hypothesis and to ignore evidence that counts against it or for some competing hypothesis. Detectives, intelligence agencies, and investigators of airplane accidents are well advised to gather relevant evidence systematically and to postpone even tentative adoption of an explanatory hypothesis until the collected evidence rules out with the appropriate degree of certainty all but one explanation. Dewey’s analysis of the critical thinking process can be faulted as well for requiring acceptance or rejection of a possible solution to a defined problem, with no allowance for deciding in the light of the available evidence to suspend judgment. Further, given the great variety of kinds of problems for which reflection is appropriate, there is likely to be variation in its component events. Perhaps the best way to conceptualize the critical thinking process is as a checklist whose component events can occur in a variety of orders, selectively, and more than once. These component events might include (1) noticing a difficulty, (2) defining the problem, (3) dividing the problem into manageable sub-problems, (4) formulating a variety of possible solutions to the problem or sub-problem, (5) determining what evidence is relevant to deciding among possible solutions to the problem or sub-problem, (6) devising a plan of systematic observation or experiment that will uncover the relevant evidence, (7) carrying out the plan of systematic observation or experimentation, (8) noting the results of the systematic observation or experiment, (9) gathering relevant testimony and information from others, (10) judging the credibility of testimony and information gathered from others, (11) drawing conclusions from gathered evidence and accepted testimony, and (12) accepting a solution that the evidence adequately supports (cf. Hitchcock 2017: 485).

Checklist conceptions of the process of critical thinking are open to the objection that they are too mechanical and procedural to fit the multi-dimensional and emotionally charged issues for which critical thinking is urgently needed (Paul 1984). For such issues, a more dialectical process is advocated, in which competing relevant world views are identified, their implications explored, and some sort of creative synthesis attempted.

If one considers the critical thinking process illustrated by the 11 examples, one can identify distinct kinds of mental acts and mental states that form part of it. To distinguish, label and briefly characterize these components is a useful preliminary to identifying abilities, skills, dispositions, attitudes, habits and the like that contribute causally to thinking critically. Identifying such abilities and habits is in turn a useful preliminary to setting educational goals. Setting the goals is in its turn a useful preliminary to designing strategies for helping learners to achieve the goals and to designing ways of measuring the extent to which learners have done so. Such measures provide both feedback to learners on their achievement and a basis for experimental research on the effectiveness of various strategies for educating people to think critically. Let us begin, then, by distinguishing the kinds of mental acts and mental events that can occur in a critical thinking process.

• Observing : One notices something in one’s immediate environment (sudden cooling of temperature in Weather , bubbles forming outside a glass and then going inside in Bubbles , a moving blur in the distance in Blur , a rash in Rash ). Or one notes the results of an experiment or systematic observation (valuables missing in Disorder , no suction without air pressure in Suction pump )
• Feeling : One feels puzzled or uncertain about something (how to get to an appointment on time in Transit , why the diamonds vary in spacing in Diamond ). One wants to resolve this perplexity. One feels satisfaction once one has worked out an answer (to take the subway express in Transit , diamonds closer when needed as a warning in Diamond ).
• Wondering : One formulates a question to be addressed (why bubbles form outside a tumbler taken from hot water in Bubbles , how suction pumps work in Suction pump , what caused the rash in Rash ).
• Imagining : One thinks of possible answers (bus or subway or elevated in Transit , flagpole or ornament or wireless communication aid or direction indicator in Ferryboat , allergic reaction or heat rash in Rash ).
• Inferring : One works out what would be the case if a possible answer were assumed (valuables missing if there has been a burglary in Disorder , earlier start to the rash if it is an allergic reaction to a sulfa drug in Rash ). Or one draws a conclusion once sufficient relevant evidence is gathered (take the subway in Transit , burglary in Disorder , discontinue blood pressure medication and new cream in Rash ).
• Knowledge : One uses stored knowledge of the subject-matter to generate possible answers or to infer what would be expected on the assumption of a particular answer (knowledge of a city’s public transit system in Transit , of the requirements for a flagpole in Ferryboat , of Boyle’s law in Bubbles , of allergic reactions in Rash ).
• Experimenting : One designs and carries out an experiment or a systematic observation to find out whether the results deduced from a possible answer will occur (looking at the location of the flagpole in relation to the pilot’s position in Ferryboat , putting an ice cube on top of a tumbler taken from hot water in Bubbles , measuring the height to which a suction pump will draw water at different elevations in Suction pump , noticing the spacing of diamonds when movement to or from a diamond lane is allowed in Diamond ).
• Consulting : One finds a source of information, gets the information from the source, and makes a judgment on whether to accept it. None of our 11 examples include searching for sources of information. In this respect they are unrepresentative, since most people nowadays have almost instant access to information relevant to answering any question, including many of those illustrated by the examples. However, Candidate includes the activities of extracting information from sources and evaluating its credibility.
• Identifying and analyzing arguments : One notices an argument and works out its structure and content as a preliminary to evaluating its strength. This activity is central to Candidate . It is an important part of a critical thinking process in which one surveys arguments for various positions on an issue.
• Judging : One makes a judgment on the basis of accumulated evidence and reasoning, such as the judgment in Ferryboat that the purpose of the pole is to provide direction to the pilot.
• Deciding : One makes a decision on what to do or on what policy to adopt, as in the decision in Transit to take the subway.

By definition, a person who does something voluntarily is both willing and able to do that thing at that time. Both the willingness and the ability contribute causally to the person’s action, in the sense that the voluntary action would not occur if either (or both) of these were lacking. For example, suppose that one is standing with one’s arms at one’s sides and one voluntarily lifts one’s right arm to an extended horizontal position. One would not do so if one were unable to lift one’s arm, if for example one’s right side was paralyzed as the result of a stroke. Nor would one do so if one were unwilling to lift one’s arm, if for example one were participating in a street demonstration at which a white supremacist was urging the crowd to lift their right arm in a Nazi salute and one were unwilling to express support in this way for the racist Nazi ideology. The same analysis applies to a voluntary mental process of thinking critically. It requires both willingness and ability to think critically, including willingness and ability to perform each of the mental acts that compose the process and to coordinate those acts in a sequence that is directed at resolving the initiating perplexity.

Consider willingness first. We can identify causal contributors to willingness to think critically by considering factors that would cause a person who was able to think critically about an issue nevertheless not to do so (Hamby 2014). For each factor, the opposite condition thus contributes causally to willingness to think critically on a particular occasion. For example, people who habitually jump to conclusions without considering alternatives will not think critically about issues that arise, even if they have the required abilities. The contrary condition of willingness to suspend judgment is thus a causal contributor to thinking critically.

Now consider ability. In contrast to the ability to move one’s arm, which can be completely absent because a stroke has left the arm paralyzed, the ability to think critically is a developed ability, whose absence is not a complete absence of ability to think but absence of ability to think well. We can identify the ability to think well directly, in terms of the norms and standards for good thinking. In general, to be able do well the thinking activities that can be components of a critical thinking process, one needs to know the concepts and principles that characterize their good performance, to recognize in particular cases that the concepts and principles apply, and to apply them. The knowledge, recognition and application may be procedural rather than declarative. It may be domain-specific rather than widely applicable, and in either case may need subject-matter knowledge, sometimes of a deep kind.

Reflections of the sort illustrated by the previous two paragraphs have led scholars to identify the knowledge, abilities and dispositions of a “critical thinker”, i.e., someone who thinks critically whenever it is appropriate to do so. We turn now to these three types of causal contributors to thinking critically. We start with dispositions, since arguably these are the most powerful contributors to being a critical thinker, can be fostered at an early stage of a child’s development, and are susceptible to general improvement (Glaser 1941: 175)

8. Critical Thinking Dispositions

Educational researchers use the term ‘dispositions’ broadly for the habits of mind and attitudes that contribute causally to being a critical thinker. Some writers (e.g., Paul & Elder 2006; Hamby 2014; Bailin & Battersby 2016a) propose to use the term ‘virtues’ for this dimension of a critical thinker. The virtues in question, although they are virtues of character, concern the person’s ways of thinking rather than the person’s ways of behaving towards others. They are not moral virtues but intellectual virtues, of the sort articulated by Zagzebski (1996) and discussed by Turri, Alfano, and Greco (2017).

On a realistic conception, thinking dispositions or intellectual virtues are real properties of thinkers. They are general tendencies, propensities, or inclinations to think in particular ways in particular circumstances, and can be genuinely explanatory (Siegel 1999). Sceptics argue that there is no evidence for a specific mental basis for the habits of mind that contribute to thinking critically, and that it is pedagogically misleading to posit such a basis (Bailin et al. 1999a). Whatever their status, critical thinking dispositions need motivation for their initial formation in a child—motivation that may be external or internal. As children develop, the force of habit will gradually become important in sustaining the disposition (Nieto & Valenzuela 2012). Mere force of habit, however, is unlikely to sustain critical thinking dispositions. Critical thinkers must value and enjoy using their knowledge and abilities to think things through for themselves. They must be committed to, and lovers of, inquiry.

A person may have a critical thinking disposition with respect to only some kinds of issues. For example, one could be open-minded about scientific issues but not about religious issues. Similarly, one could be confident in one’s ability to reason about the theological implications of the existence of evil in the world but not in one’s ability to reason about the best design for a guided ballistic missile.

Facione (1990a: 25) divides “affective dispositions” of critical thinking into approaches to life and living in general and approaches to specific issues, questions or problems. Adapting this distinction, one can usefully divide critical thinking dispositions into initiating dispositions (those that contribute causally to starting to think critically about an issue) and internal dispositions (those that contribute causally to doing a good job of thinking critically once one has started). The two categories are not mutually exclusive. For example, open-mindedness, in the sense of willingness to consider alternative points of view to one’s own, is both an initiating and an internal disposition.

Using the strategy of considering factors that would block people with the ability to think critically from doing so, we can identify as initiating dispositions for thinking critically attentiveness, a habit of inquiry, self-confidence, courage, open-mindedness, willingness to suspend judgment, trust in reason, wanting evidence for one’s beliefs, and seeking the truth. We consider briefly what each of these dispositions amounts to, in each case citing sources that acknowledge them.

• Attentiveness : One will not think critically if one fails to recognize an issue that needs to be thought through. For example, the pedestrian in Weather would not have looked up if he had not noticed that the air was suddenly cooler. To be a critical thinker, then, one needs to be habitually attentive to one’s surroundings, noticing not only what one senses but also sources of perplexity in messages received and in one’s own beliefs and attitudes (Facione 1990a: 25; Facione, Facione, & Giancarlo 2001).
• Habit of inquiry : Inquiry is effortful, and one needs an internal push to engage in it. For example, the student in Bubbles could easily have stopped at idle wondering about the cause of the bubbles rather than reasoning to a hypothesis, then designing and executing an experiment to test it. Thus willingness to think critically needs mental energy and initiative. What can supply that energy? Love of inquiry, or perhaps just a habit of inquiry. Hamby (2015) has argued that willingness to inquire is the central critical thinking virtue, one that encompasses all the others. It is recognized as a critical thinking disposition by Dewey (1910: 29; 1933: 35), Glaser (1941: 5), Ennis (1987: 12; 1991: 8), Facione (1990a: 25), Bailin et al. (1999b: 294), Halpern (1998: 452), and Facione, Facione, & Giancarlo (2001).
• Self-confidence : Lack of confidence in one’s abilities can block critical thinking. For example, if the woman in Rash lacked confidence in her ability to figure things out for herself, she might just have assumed that the rash on her chest was the allergic reaction to her medication against which the pharmacist had warned her. Thus willingness to think critically requires confidence in one’s ability to inquire (Facione 1990a: 25; Facione, Facione, & Giancarlo 2001).
• Courage : Fear of thinking for oneself can stop one from doing it. Thus willingness to think critically requires intellectual courage (Paul & Elder 2006: 16).
• Open-mindedness : A dogmatic attitude will impede thinking critically. For example, a person who adheres rigidly to a “pro-choice” position on the issue of the legal status of induced abortion is likely to be unwilling to consider seriously the issue of when in its development an unborn child acquires a moral right to life. Thus willingness to think critically requires open-mindedness, in the sense of a willingness to examine questions to which one already accepts an answer but which further evidence or reasoning might cause one to answer differently (Dewey 1933; Facione 1990a; Ennis 1991; Bailin et al. 1999b; Halpern 1998, Facione, Facione, & Giancarlo 2001). Paul (1981) emphasizes open-mindedness about alternative world-views, and recommends a dialectical approach to integrating such views as central to what he calls “strong sense” critical thinking. In three studies, Haran, Ritov, & Mellers (2013) found that actively open-minded thinking, including “the tendency to weigh new evidence against a favored belief, to spend sufficient time on a problem before giving up, and to consider carefully the opinions of others in forming one’s own”, led study participants to acquire information and thus to make accurate estimations.
• Willingness to suspend judgment : Premature closure on an initial solution will block critical thinking. Thus willingness to think critically requires a willingness to suspend judgment while alternatives are explored (Facione 1990a; Ennis 1991; Halpern 1998).
• Trust in reason : Since distrust in the processes of reasoned inquiry will dissuade one from engaging in it, trust in them is an initiating critical thinking disposition (Facione 1990a, 25; Bailin et al. 1999b: 294; Facione, Facione, & Giancarlo 2001; Paul & Elder 2006). In reaction to an allegedly exclusive emphasis on reason in critical thinking theory and pedagogy, Thayer-Bacon (2000) argues that intuition, imagination, and emotion have important roles to play in an adequate conception of critical thinking that she calls “constructive thinking”. From her point of view, critical thinking requires trust not only in reason but also in intuition, imagination, and emotion.
• Seeking the truth : If one does not care about the truth but is content to stick with one’s initial bias on an issue, then one will not think critically about it. Seeking the truth is thus an initiating critical thinking disposition (Bailin et al. 1999b: 294; Facione, Facione, & Giancarlo 2001). A disposition to seek the truth is implicit in more specific critical thinking dispositions, such as trying to be well-informed, considering seriously points of view other than one’s own, looking for alternatives, suspending judgment when the evidence is insufficient, and adopting a position when the evidence supporting it is sufficient.

Some of the initiating dispositions, such as open-mindedness and willingness to suspend judgment, are also internal critical thinking dispositions, in the sense of mental habits or attitudes that contribute causally to doing a good job of critical thinking once one starts the process. But there are many other internal critical thinking dispositions. Some of them are parasitic on one’s conception of good thinking. For example, it is constitutive of good thinking about an issue to formulate the issue clearly and to maintain focus on it. For this purpose, one needs not only the corresponding ability but also the corresponding disposition. Ennis (1991: 8) describes it as the disposition “to determine and maintain focus on the conclusion or question”, Facione (1990a: 25) as “clarity in stating the question or concern”. Other internal dispositions are motivators to continue or adjust the critical thinking process, such as willingness to persist in a complex task and willingness to abandon nonproductive strategies in an attempt to self-correct (Halpern 1998: 452). For a list of identified internal critical thinking dispositions, see the Supplement on Internal Critical Thinking Dispositions .

Some theorists postulate skills, i.e., acquired abilities, as operative in critical thinking. It is not obvious, however, that a good mental act is the exercise of a generic acquired skill. Inferring an expected time of arrival, as in Transit , has some generic components but also uses non-generic subject-matter knowledge. Bailin et al. (1999a) argue against viewing critical thinking skills as generic and discrete, on the ground that skilled performance at a critical thinking task cannot be separated from knowledge of concepts and from domain-specific principles of good thinking. Talk of skills, they concede, is unproblematic if it means merely that a person with critical thinking skills is capable of intelligent performance.

Despite such scepticism, theorists of critical thinking have listed as general contributors to critical thinking what they variously call abilities (Glaser 1941; Ennis 1962, 1991), skills (Facione 1990a; Halpern 1998) or competencies (Fisher & Scriven 1997). Amalgamating these lists would produce a confusing and chaotic cornucopia of more than 50 possible educational objectives, with only partial overlap among them. It makes sense instead to try to understand the reasons for the multiplicity and diversity, and to make a selection according to one’s own reasons for singling out abilities to be developed in a critical thinking curriculum. Two reasons for diversity among lists of critical thinking abilities are the underlying conception of critical thinking and the envisaged educational level. Appraisal-only conceptions, for example, involve a different suite of abilities than constructive-only conceptions. Some lists, such as those in (Glaser 1941), are put forward as educational objectives for secondary school students, whereas others are proposed as objectives for college students (e.g., Facione 1990a).

The abilities described in the remaining paragraphs of this section emerge from reflection on the general abilities needed to do well the thinking activities identified in section 6 as components of the critical thinking process described in section 5 . The derivation of each collection of abilities is accompanied by citation of sources that list such abilities and of standardized tests that claim to test them.

Observational abilities : Careful and accurate observation sometimes requires specialist expertise and practice, as in the case of observing birds and observing accident scenes. However, there are general abilities of noticing what one’s senses are picking up from one’s environment and of being able to articulate clearly and accurately to oneself and others what one has observed. It helps in exercising them to be able to recognize and take into account factors that make one’s observation less trustworthy, such as prior framing of the situation, inadequate time, deficient senses, poor observation conditions, and the like. It helps as well to be skilled at taking steps to make one’s observation more trustworthy, such as moving closer to get a better look, measuring something three times and taking the average, and checking what one thinks one is observing with someone else who is in a good position to observe it. It also helps to be skilled at recognizing respects in which one’s report of one’s observation involves inference rather than direct observation, so that one can then consider whether the inference is justified. These abilities come into play as well when one thinks about whether and with what degree of confidence to accept an observation report, for example in the study of history or in a criminal investigation or in assessing news reports. Observational abilities show up in some lists of critical thinking abilities (Ennis 1962: 90; Facione 1990a: 16; Ennis 1991: 9). There are items testing a person’s ability to judge the credibility of observation reports in the Cornell Critical Thinking Tests, Levels X and Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005). Norris and King (1983, 1985, 1990a, 1990b) is a test of ability to appraise observation reports.

Emotional abilities : The emotions that drive a critical thinking process are perplexity or puzzlement, a wish to resolve it, and satisfaction at achieving the desired resolution. Children experience these emotions at an early age, without being trained to do so. Education that takes critical thinking as a goal needs only to channel these emotions and to make sure not to stifle them. Collaborative critical thinking benefits from ability to recognize one’s own and others’ emotional commitments and reactions.

Questioning abilities : A critical thinking process needs transformation of an inchoate sense of perplexity into a clear question. Formulating a question well requires not building in questionable assumptions, not prejudging the issue, and using language that in context is unambiguous and precise enough (Ennis 1962: 97; 1991: 9).

Imaginative abilities : Thinking directed at finding the correct causal explanation of a general phenomenon or particular event requires an ability to imagine possible explanations. Thinking about what policy or plan of action to adopt requires generation of options and consideration of possible consequences of each option. Domain knowledge is required for such creative activity, but a general ability to imagine alternatives is helpful and can be nurtured so as to become easier, quicker, more extensive, and deeper (Dewey 1910: 34–39; 1933: 40–47). Facione (1990a) and Halpern (1998) include the ability to imagine alternatives as a critical thinking ability.

Inferential abilities : The ability to draw conclusions from given information, and to recognize with what degree of certainty one’s own or others’ conclusions follow, is universally recognized as a general critical thinking ability. All 11 examples in section 2 of this article include inferences, some from hypotheses or options (as in Transit , Ferryboat and Disorder ), others from something observed (as in Weather and Rash ). None of these inferences is formally valid. Rather, they are licensed by general, sometimes qualified substantive rules of inference (Toulmin 1958) that rest on domain knowledge—that a bus trip takes about the same time in each direction, that the terminal of a wireless telegraph would be located on the highest possible place, that sudden cooling is often followed by rain, that an allergic reaction to a sulfa drug generally shows up soon after one starts taking it. It is a matter of controversy to what extent the specialized ability to deduce conclusions from premisses using formal rules of inference is needed for critical thinking. Dewey (1933) locates logical forms in setting out the products of reflection rather than in the process of reflection. Ennis (1981a), on the other hand, maintains that a liberally-educated person should have the following abilities: to translate natural-language statements into statements using the standard logical operators, to use appropriately the language of necessary and sufficient conditions, to deal with argument forms and arguments containing symbols, to determine whether in virtue of an argument’s form its conclusion follows necessarily from its premisses, to reason with logically complex propositions, and to apply the rules and procedures of deductive logic. Inferential abilities are recognized as critical thinking abilities by Glaser (1941: 6), Facione (1990a: 9), Ennis (1991: 9), Fisher & Scriven (1997: 99, 111), and Halpern (1998: 452). Items testing inferential abilities constitute two of the five subtests of the Watson Glaser Critical Thinking Appraisal (Watson & Glaser 1980a, 1980b, 1994), two of the four sections in the Cornell Critical Thinking Test Level X (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005), three of the seven sections in the Cornell Critical Thinking Test Level Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005), 11 of the 34 items on Forms A and B of the California Critical Thinking Skills Test (Facione 1990b, 1992), and a high but variable proportion of the 25 selected-response questions in the Collegiate Learning Assessment (Council for Aid to Education 2017).

Experimenting abilities : Knowing how to design and execute an experiment is important not just in scientific research but also in everyday life, as in Rash . Dewey devoted a whole chapter of his How We Think (1910: 145–156; 1933: 190–202) to the superiority of experimentation over observation in advancing knowledge. Experimenting abilities come into play at one remove in appraising reports of scientific studies. Skill in designing and executing experiments includes the acknowledged abilities to appraise evidence (Glaser 1941: 6), to carry out experiments and to apply appropriate statistical inference techniques (Facione 1990a: 9), to judge inductions to an explanatory hypothesis (Ennis 1991: 9), and to recognize the need for an adequately large sample size (Halpern 1998). The Cornell Critical Thinking Test Level Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005) includes four items (out of 52) on experimental design. The Collegiate Learning Assessment (Council for Aid to Education 2017) makes room for appraisal of study design in both its performance task and its selected-response questions.

Consulting abilities : Skill at consulting sources of information comes into play when one seeks information to help resolve a problem, as in Candidate . Ability to find and appraise information includes ability to gather and marshal pertinent information (Glaser 1941: 6), to judge whether a statement made by an alleged authority is acceptable (Ennis 1962: 84), to plan a search for desired information (Facione 1990a: 9), and to judge the credibility of a source (Ennis 1991: 9). Ability to judge the credibility of statements is tested by 24 items (out of 76) in the Cornell Critical Thinking Test Level X (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005) and by four items (out of 52) in the Cornell Critical Thinking Test Level Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005). The College Learning Assessment’s performance task requires evaluation of whether information in documents is credible or unreliable (Council for Aid to Education 2017).

Argument analysis abilities : The ability to identify and analyze arguments contributes to the process of surveying arguments on an issue in order to form one’s own reasoned judgment, as in Candidate . The ability to detect and analyze arguments is recognized as a critical thinking skill by Facione (1990a: 7–8), Ennis (1991: 9) and Halpern (1998). Five items (out of 34) on the California Critical Thinking Skills Test (Facione 1990b, 1992) test skill at argument analysis. The College Learning Assessment (Council for Aid to Education 2017) incorporates argument analysis in its selected-response tests of critical reading and evaluation and of critiquing an argument.

Judging skills and deciding skills : Skill at judging and deciding is skill at recognizing what judgment or decision the available evidence and argument supports, and with what degree of confidence. It is thus a component of the inferential skills already discussed.

Lists and tests of critical thinking abilities often include two more abilities: identifying assumptions and constructing and evaluating definitions.

In addition to dispositions and abilities, critical thinking needs knowledge: of critical thinking concepts, of critical thinking principles, and of the subject-matter of the thinking.

We can derive a short list of concepts whose understanding contributes to critical thinking from the critical thinking abilities described in the preceding section. Observational abilities require an understanding of the difference between observation and inference. Questioning abilities require an understanding of the concepts of ambiguity and vagueness. Inferential abilities require an understanding of the difference between conclusive and defeasible inference (traditionally, between deduction and induction), as well as of the difference between necessary and sufficient conditions. Experimenting abilities require an understanding of the concepts of hypothesis, null hypothesis, assumption and prediction, as well as of the concept of statistical significance and of its difference from importance. They also require an understanding of the difference between an experiment and an observational study, and in particular of the difference between a randomized controlled trial, a prospective correlational study and a retrospective (case-control) study. Argument analysis abilities require an understanding of the concepts of argument, premiss, assumption, conclusion and counter-consideration. Additional critical thinking concepts are proposed by Bailin et al. (1999b: 293), Fisher & Scriven (1997: 105–106), Black (2012), and Blair (2021).

According to Glaser (1941: 25), ability to think critically requires knowledge of the methods of logical inquiry and reasoning. If we review the list of abilities in the preceding section, however, we can see that some of them can be acquired and exercised merely through practice, possibly guided in an educational setting, followed by feedback. Searching intelligently for a causal explanation of some phenomenon or event requires that one consider a full range of possible causal contributors, but it seems more important that one implements this principle in one’s practice than that one is able to articulate it. What is important is “operational knowledge” of the standards and principles of good thinking (Bailin et al. 1999b: 291–293). But the development of such critical thinking abilities as designing an experiment or constructing an operational definition can benefit from learning their underlying theory. Further, explicit knowledge of quirks of human thinking seems useful as a cautionary guide. Human memory is not just fallible about details, as people learn from their own experiences of misremembering, but is so malleable that a detailed, clear and vivid recollection of an event can be a total fabrication (Loftus 2017). People seek or interpret evidence in ways that are partial to their existing beliefs and expectations, often unconscious of their “confirmation bias” (Nickerson 1998). Not only are people subject to this and other cognitive biases (Kahneman 2011), of which they are typically unaware, but it may be counter-productive for one to make oneself aware of them and try consciously to counteract them or to counteract social biases such as racial or sexual stereotypes (Kenyon & Beaulac 2014). It is helpful to be aware of these facts and of the superior effectiveness of blocking the operation of biases—for example, by making an immediate record of one’s observations, refraining from forming a preliminary explanatory hypothesis, blind refereeing, double-blind randomized trials, and blind grading of students’ work. It is also helpful to be aware of the prevalence of “noise” (unwanted unsystematic variability of judgments), of how to detect noise (through a noise audit), and of how to reduce noise: make accuracy the goal, think statistically, break a process of arriving at a judgment into independent tasks, resist premature intuitions, in a group get independent judgments first, favour comparative judgments and scales (Kahneman, Sibony, & Sunstein 2021). It is helpful as well to be aware of the concept of “bounded rationality” in decision-making and of the related distinction between “satisficing” and optimizing (Simon 1956; Gigerenzer 2001).

Critical thinking about an issue requires substantive knowledge of the domain to which the issue belongs. Critical thinking abilities are not a magic elixir that can be applied to any issue whatever by somebody who has no knowledge of the facts relevant to exploring that issue. For example, the student in Bubbles needed to know that gases do not penetrate solid objects like a glass, that air expands when heated, that the volume of an enclosed gas varies directly with its temperature and inversely with its pressure, and that hot objects will spontaneously cool down to the ambient temperature of their surroundings unless kept hot by insulation or a source of heat. Critical thinkers thus need a rich fund of subject-matter knowledge relevant to the variety of situations they encounter. This fact is recognized in the inclusion among critical thinking dispositions of a concern to become and remain generally well informed.

Experimental educational interventions, with control groups, have shown that education can improve critical thinking skills and dispositions, as measured by standardized tests. For information about these tests, see the Supplement on Assessment .

What educational methods are most effective at developing the dispositions, abilities and knowledge of a critical thinker? In a comprehensive meta-analysis of experimental and quasi-experimental studies of strategies for teaching students to think critically, Abrami et al. (2015) found that dialogue, anchored instruction, and mentoring each increased the effectiveness of the educational intervention, and that they were most effective when combined. They also found that in these studies a combination of separate instruction in critical thinking with subject-matter instruction in which students are encouraged to think critically was more effective than either by itself. However, the difference was not statistically significant; that is, it might have arisen by chance.

Most of these studies lack the longitudinal follow-up required to determine whether the observed differential improvements in critical thinking abilities or dispositions continue over time, for example until high school or college graduation. For details on studies of methods of developing critical thinking skills and dispositions, see the Supplement on Educational Methods .

12. Controversies

Scholars have denied the generalizability of critical thinking abilities across subject domains, have alleged bias in critical thinking theory and pedagogy, and have investigated the relationship of critical thinking to other kinds of thinking.

McPeck (1981) attacked the thinking skills movement of the 1970s, including the critical thinking movement. He argued that there are no general thinking skills, since thinking is always thinking about some subject-matter. It is futile, he claimed, for schools and colleges to teach thinking as if it were a separate subject. Rather, teachers should lead their pupils to become autonomous thinkers by teaching school subjects in a way that brings out their cognitive structure and that encourages and rewards discussion and argument. As some of his critics (e.g., Paul 1985; Siegel 1985) pointed out, McPeck’s central argument needs elaboration, since it has obvious counter-examples in writing and speaking, for which (up to a certain level of complexity) there are teachable general abilities even though they are always about some subject-matter. To make his argument convincing, McPeck needs to explain how thinking differs from writing and speaking in a way that does not permit useful abstraction of its components from the subject-matters with which it deals. He has not done so. Nevertheless, his position that the dispositions and abilities of a critical thinker are best developed in the context of subject-matter instruction is shared by many theorists of critical thinking, including Dewey (1910, 1933), Glaser (1941), Passmore (1980), Weinstein (1990), Bailin et al. (1999b), and Willingham (2019).

McPeck’s challenge prompted reflection on the extent to which critical thinking is subject-specific. McPeck argued for a strong subject-specificity thesis, according to which it is a conceptual truth that all critical thinking abilities are specific to a subject. (He did not however extend his subject-specificity thesis to critical thinking dispositions. In particular, he took the disposition to suspend judgment in situations of cognitive dissonance to be a general disposition.) Conceptual subject-specificity is subject to obvious counter-examples, such as the general ability to recognize confusion of necessary and sufficient conditions. A more modest thesis, also endorsed by McPeck, is epistemological subject-specificity, according to which the norms of good thinking vary from one field to another. Epistemological subject-specificity clearly holds to a certain extent; for example, the principles in accordance with which one solves a differential equation are quite different from the principles in accordance with which one determines whether a painting is a genuine Picasso. But the thesis suffers, as Ennis (1989) points out, from vagueness of the concept of a field or subject and from the obvious existence of inter-field principles, however broadly the concept of a field is construed. For example, the principles of hypothetico-deductive reasoning hold for all the varied fields in which such reasoning occurs. A third kind of subject-specificity is empirical subject-specificity, according to which as a matter of empirically observable fact a person with the abilities and dispositions of a critical thinker in one area of investigation will not necessarily have them in another area of investigation.

The thesis of empirical subject-specificity raises the general problem of transfer. If critical thinking abilities and dispositions have to be developed independently in each school subject, how are they of any use in dealing with the problems of everyday life and the political and social issues of contemporary society, most of which do not fit into the framework of a traditional school subject? Proponents of empirical subject-specificity tend to argue that transfer is more likely to occur if there is critical thinking instruction in a variety of domains, with explicit attention to dispositions and abilities that cut across domains. But evidence for this claim is scanty. There is a need for well-designed empirical studies that investigate the conditions that make transfer more likely.

It is common ground in debates about the generality or subject-specificity of critical thinking dispositions and abilities that critical thinking about any topic requires background knowledge about the topic. For example, the most sophisticated understanding of the principles of hypothetico-deductive reasoning is of no help unless accompanied by some knowledge of what might be plausible explanations of some phenomenon under investigation.

Critics have objected to bias in the theory, pedagogy and practice of critical thinking. Commentators (e.g., Alston 1995; Ennis 1998) have noted that anyone who takes a position has a bias in the neutral sense of being inclined in one direction rather than others. The critics, however, are objecting to bias in the pejorative sense of an unjustified favoring of certain ways of knowing over others, frequently alleging that the unjustly favoured ways are those of a dominant sex or culture (Bailin 1995). These ways favour:

• reinforcement of egocentric and sociocentric biases over dialectical engagement with opposing world-views (Paul 1981, 1984; Warren 1998)
• distancing from the object of inquiry over closeness to it (Martin 1992; Thayer-Bacon 1992)
• indifference to the situation of others over care for them (Martin 1992)
• orientation to thought over orientation to action (Martin 1992)
• being reasonable over caring to understand people’s ideas (Thayer-Bacon 1993)
• being neutral and objective over being embodied and situated (Thayer-Bacon 1995a)
• doubting over believing (Thayer-Bacon 1995b)
• reason over emotion, imagination and intuition (Thayer-Bacon 2000)
• solitary thinking over collaborative thinking (Thayer-Bacon 2000)
• written and spoken assignments over other forms of expression (Alston 2001)
• attention to written and spoken communications over attention to human problems (Alston 2001)
• winning debates in the public sphere over making and understanding meaning (Alston 2001)

A common thread in this smorgasbord of accusations is dissatisfaction with focusing on the logical analysis and evaluation of reasoning and arguments. While these authors acknowledge that such analysis and evaluation is part of critical thinking and should be part of its conceptualization and pedagogy, they insist that it is only a part. Paul (1981), for example, bemoans the tendency of atomistic teaching of methods of analyzing and evaluating arguments to turn students into more able sophists, adept at finding fault with positions and arguments with which they disagree but even more entrenched in the egocentric and sociocentric biases with which they began. Martin (1992) and Thayer-Bacon (1992) cite with approval the self-reported intimacy with their subject-matter of leading researchers in biology and medicine, an intimacy that conflicts with the distancing allegedly recommended in standard conceptions and pedagogy of critical thinking. Thayer-Bacon (2000) contrasts the embodied and socially embedded learning of her elementary school students in a Montessori school, who used their imagination, intuition and emotions as well as their reason, with conceptions of critical thinking as

thinking that is used to critique arguments, offer justifications, and make judgments about what are the good reasons, or the right answers. (Thayer-Bacon 2000: 127–128)

Alston (2001) reports that her students in a women’s studies class were able to see the flaws in the Cinderella myth that pervades much romantic fiction but in their own romantic relationships still acted as if all failures were the woman’s fault and still accepted the notions of love at first sight and living happily ever after. Students, she writes, should

be able to connect their intellectual critique to a more affective, somatic, and ethical account of making risky choices that have sexist, racist, classist, familial, sexual, or other consequences for themselves and those both near and far… critical thinking that reads arguments, texts, or practices merely on the surface without connections to feeling/desiring/doing or action lacks an ethical depth that should infuse the difference between mere cognitive activity and something we want to call critical thinking. (Alston 2001: 34)

Some critics portray such biases as unfair to women. Thayer-Bacon (1992), for example, has charged modern critical thinking theory with being sexist, on the ground that it separates the self from the object and causes one to lose touch with one’s inner voice, and thus stigmatizes women, who (she asserts) link self to object and listen to their inner voice. Her charge does not imply that women as a group are on average less able than men to analyze and evaluate arguments. Facione (1990c) found no difference by sex in performance on his California Critical Thinking Skills Test. Kuhn (1991: 280–281) found no difference by sex in either the disposition or the competence to engage in argumentative thinking.

The critics propose a variety of remedies for the biases that they allege. In general, they do not propose to eliminate or downplay critical thinking as an educational goal. Rather, they propose to conceptualize critical thinking differently and to change its pedagogy accordingly. Their pedagogical proposals arise logically from their objections. They can be summarized as follows:

• Focus on argument networks with dialectical exchanges reflecting contesting points of view rather than on atomic arguments, so as to develop “strong sense” critical thinking that transcends egocentric and sociocentric biases (Paul 1981, 1984).
• Foster closeness to the subject-matter and feeling connected to others in order to inform a humane democracy (Martin 1992).
• Develop “constructive thinking” as a social activity in a community of physically embodied and socially embedded inquirers with personal voices who value not only reason but also imagination, intuition and emotion (Thayer-Bacon 2000).
• In developing critical thinking in school subjects, treat as important neither skills nor dispositions but opening worlds of meaning (Alston 2001).
• Attend to the development of critical thinking dispositions as well as skills, and adopt the “critical pedagogy” practised and advocated by Freire (1968 [1970]) and hooks (1994) (Dalgleish, Girard, & Davies 2017).

A common thread in these proposals is treatment of critical thinking as a social, interactive, personally engaged activity like that of a quilting bee or a barn-raising (Thayer-Bacon 2000) rather than as an individual, solitary, distanced activity symbolized by Rodin’s The Thinker . One can get a vivid description of education with the former type of goal from the writings of bell hooks (1994, 2010). Critical thinking for her is open-minded dialectical exchange across opposing standpoints and from multiple perspectives, a conception similar to Paul’s “strong sense” critical thinking (Paul 1981). She abandons the structure of domination in the traditional classroom. In an introductory course on black women writers, for example, she assigns students to write an autobiographical paragraph about an early racial memory, then to read it aloud as the others listen, thus affirming the uniqueness and value of each voice and creating a communal awareness of the diversity of the group’s experiences (hooks 1994: 84). Her “engaged pedagogy” is thus similar to the “freedom under guidance” implemented in John Dewey’s Laboratory School of Chicago in the late 1890s and early 1900s. It incorporates the dialogue, anchored instruction, and mentoring that Abrami (2015) found to be most effective in improving critical thinking skills and dispositions.

What is the relationship of critical thinking to problem solving, decision-making, higher-order thinking, creative thinking, and other recognized types of thinking? One’s answer to this question obviously depends on how one defines the terms used in the question. If critical thinking is conceived broadly to cover any careful thinking about any topic for any purpose, then problem solving and decision making will be kinds of critical thinking, if they are done carefully. Historically, ‘critical thinking’ and ‘problem solving’ were two names for the same thing. If critical thinking is conceived more narrowly as consisting solely of appraisal of intellectual products, then it will be disjoint with problem solving and decision making, which are constructive.

Bloom’s taxonomy of educational objectives used the phrase “intellectual abilities and skills” for what had been labeled “critical thinking” by some, “reflective thinking” by Dewey and others, and “problem solving” by still others (Bloom et al. 1956: 38). Thus, the so-called “higher-order thinking skills” at the taxonomy’s top levels of analysis, synthesis and evaluation are just critical thinking skills, although they do not come with general criteria for their assessment (Ennis 1981b). The revised version of Bloom’s taxonomy (Anderson et al. 2001) likewise treats critical thinking as cutting across those types of cognitive process that involve more than remembering (Anderson et al. 2001: 269–270). For details, see the Supplement on History .

As to creative thinking, it overlaps with critical thinking (Bailin 1987, 1988). Thinking about the explanation of some phenomenon or event, as in Ferryboat , requires creative imagination in constructing plausible explanatory hypotheses. Likewise, thinking about a policy question, as in Candidate , requires creativity in coming up with options. Conversely, creativity in any field needs to be balanced by critical appraisal of the draft painting or novel or mathematical theory.

The 17 Best Books on Critical Thinking (to Read in 2024)

All products were independently selected by our editors and contributors. When you buy through links on our site, we may earn an affiliate commission.

The aim of improving your skill of critical thinking isn’t just to be able to reason and give logical arguments about a subject skillfully; your goal is to get to the right answer, to make the right decisions and choices for yourself and others.

Critical thinking helps you:

First , improve the quality of your decisions and judgments, and reevaluate your beliefs objectively.

The human mind is rarely objective. However, mastering the skill of critical thinking keeps your mind objective, at least about those things based on facts.

Take for example the beliefs you have about yourself; Some are based on facts, some on subjective (negative) opinions of others.

Second , become an independent thinker (learn to think for yourself); take ownership of your values, beliefs, judgments, and decisions.

Mastering critical thinking is essential , especially in our modern times, because you must:

• Make a tone of decisions every day;
• Think and come to the right conclusion fast;
• Solve (mostly alone) your problems and issues;
• Weigh carefully facts and information you receive from the dozens of sources you have at your disposal;
• Reevaluate your strategies, beliefs, and habits periodically.

Critical thinking is a skill that you must learn; you’re not born with it. To make your journey a little easier, we’ve gathered the best critical thinking books so you can learn from the masters. Get inspired to become a critical thinker in no time!

The best books on critical thinking:

The book starts with the five fundamental questions:

• Couldn’t we at least…?
• How can I help…?
• What truly matters….?

Knowing how to formulate, address, and deliver the right questions doesn’t leave room for misunderstandings, misinterpretations; asking the wrong questions will most probably give you a wrong answer.

This book (Wait, What?: And Life’s Other Essential Questions) will make you feel (more) courageous; after all, asking questions thanks courage. Asking yourself and others the right questions helps you make informed decisions and decisive action.

This book is a guide on how to train your brain to work even more for you. The author (Michael Kallet) is a critical thinking trainer and coach and gives you a practical set of tools and techniques for critical thinking in your day-to-day life and business.

If you want a clear, actionable step by step program to:

• Improve your critical thinking skills,
• A better understanding of complex problems and concepts,
• And how to put them in practice, then this book is for you.

The book is packed with practical exercises, fascinating illustrations, games, and puzzles to improve your mental capabilities.

The art of thinking Clearly by Rolf Dobelli is a window into human psychology and reasoning; how we:

• Make decisions;
• Evaluate choices and options;
• Develop cognitive biases.

This book helps you notice and recognize erroneous thinking and make better choices and decisions, change unwanted behaviors and habits.

It will change the way you think about yourself and life in general because you have in this book 99 short chapters with examples of the most common errors of judgment and how to rectify them.

If you wish to think more clearly, make better decisions and choices, reevaluate your biases, and feel better about yourself, this book is for you.

When you decide you want to study the field of logic more closely and improve your critical thinking, this book might be exactly what you need. It’s written clearly and concisely laying out for you the basic building blocks of logic and critical thinking.

The ancient civilizations understood better than us how important is to study logic and rhetoric. With the help of this book, you’ll bring back into your life these essential things that our modern society forgot and missed to teach you as a child.

Having increased logical thinking doesn’t mean to ignore your emotions. It means to start from your emotions and together, (emotions and logic) to take better decisions and see more clearly your choices to move forward in life.

“Predictably Irrational, The Hidden Forces That Shape Our Decisions” is a book packed with examples of how:

• Irrational are our choices;
• We make decisions on impulse;
• We fool ourselves with optimism- “that must work for me.”

The author presents you, in this book, a large number of mental traps and flawed tendencies which can make your life harder.

After reading this book, you’ll be better informed about a variety of human flaws and how to avoid being trapped by irrational thinking. You’ll be better prepared to make decisions and choices based more on facts rather than subjective personal opinions.

Knowing how to ask the right questions is determining your success about many things in your life:

• Influencing others,
• Getting out of tricky situations,
• Reevaluating your beliefs,
• Offering yourself and others compassion,
• Overcoming mistakes and fears.

Warren Berger shows you in this book examples of people who are successful (partially) because they are experts in asking questions and don’t have preconceived ideas about what the answers should be.

This book helps you avoid wasting your innovative and brilliant ideas by presenting them in the same way over and over and getting nowhere over and over.

Asking yourself (and others) the right questions gives you the opportunity to display your ideas in a way that those around you feel compelled to listen.

This book is impressive because, Anthony Weston gives you a lot of excellent and practical advice, ordered in a logical and clear manner.

The examples in this book are realistic and useful, ranging from deductive to oral arguments, from argumentative essays to arguments by analogy.

Once you read this book you’ll want to have it on hand to sort out all sorts of situations you’ll encounter in your day-to-day life.

Daniel Kahneman, the author of this book, is a renowned psychologist and winner of the Nobel Prize in economics.

In this book, you will discover where you can and cannot trust your intuition; how to use the two systems that drive the way you think.

The first system is fast, intuitive, and emotional; the second system is slower, based on facts, and more logical.

The author argues that knowing how to use these two systems can make a huge difference in how you:

• Design your strategies,
• Predict consequences,
• Avoid cognitive biases,
• (and even simple things like) choosing the colors for your home office.

If you want to improve your critical thinking, know when you should use logic (instead of using emotions), and become mentally stronger this book is definitely for you.

Critical thinking can’t be created in a cluttered mind. It’s like trying to prepare a gourmet meal for your loved ones in a cramped and dysfunctional kitchen.

As if is not enough all the information you store in your mind from what you personally experience every day, our modern times forcefully adds to that information a lot of junk.

The book “The Organized Mind: Thinking Straight in the Age of Information Overload” by Daniel J. Levitin will help you sort out and organized your thoughts with the help of the four components in the human attentional system:

• Mind wandering mode;
• Central executive mode;
• Attentional filter;
• Attentional switch.

The book is showing you how you can improve your critical thinking and make better decisions concerning many areas of your life.

This book can (really) change your life if you’re dealing with procrastination, multitasking, the inability to switch off and block the outside world.

All in all, you’ll be better prepared to think straight in the age of information overload.

Thomas E. Kida talks in this book very elegantly about the six basic mistakes your thinking can make.

• The first mistake is being mesmerized by stories and ignoring the facts or statistics.
• The second mistake is searching to confirm what we already know or believe.
• The third mistake is to discount the role that chance and coincidence play in our life.
• The fourth mistake is believing that what you see it’s always the reality.
• The fifth mistake is to oversimplify things.
• The sixth mistake is to believe (trust) faulty memories.

This book can be for you an eye-opener into critical thinking, accepting who you are as you are, and improving the way you choose and make decisions.

Did you know you have a strategy for everything you do? From brushing your teeth to making new friends? From choosing a career to dealing with difficult people?

Considering you have a strategy for everything you do, it’s only logical the try to improve every day the way you develop your strategies and don’t leave it to chance, habit, or convenience.

“The Decision Book: 50 Models for Strategic Thinking” can improve your critical thinking and help you make your life easier and more enjoyable.

This book is interactive and provokes you to think about some of the strategies that don’t bring you the results you want.

It contains 58 illustrations offering summaries for known strategies such as the Rubber Band Model, the Personal Performance Model, and the Black Swan Model.

This book is for you if you want to improve the flexibility of your thinking, accept challenges more comfortable, feel more in control of your decisions and choices.

From this book, by Daniel Levitin, you’ll learn how to think critically and avoid being manipulated by things like misleading statistics and graphics, extreme view, or fake news.

The book contains three main sections:

• Evaluating numbers – how to read statistics and data to find out what lurks underneath and make a more objective analysis
• Evaluating words – how to assess the information you receive from experts, understanding the difference between incidence and prevalence, risk perceptions, and probabilistic thinking
• Evaluating the world – how to interpret scientific methods for different types of reasoning (induction, deduction, abduction)

This book will help you improve your critical thinking providing you with a lot of food for thought.

You know how in a criminal trial they call two experts that have divergent opinions on the same facts? Depending on whose side they are? This book teaches you to see the truth.

Although written in the 1990s, this bestseller book is still relevant in today’s society.

Critical thinking definition

Critical thinking, as described by Oxford Languages, is the objective analysis and evaluation of an issue in order to form a judgement.

Active and skillful approach, evaluation, assessment, synthesis, and/or evaluation of information obtained from, or made by, observation, knowledge, reflection, acumen or conversation, as a guide to belief and action, requires the critical thinking process, which is why it's often used in education and academics.

Some even may view it as a backbone of modern thought.

However, it's a skill, and skills must be trained and encouraged to be used at its full potential.

People turn up to various approaches in improving their critical thinking, like:

• Developing technical and problem-solving skills
• Engaging in more active listening
• Actively questioning their assumptions and beliefs
• Seeking out more diversity of thought
• Opening up their curiosity in an intellectual way etc.

Is critical thinking useful in writing?

Critical thinking can help in planning your paper and making it more concise, but it's not obvious at first. We carefully pinpointed some the questions you should ask yourself when boosting critical thinking in writing:

• What information should be included?
• Which information resources should the author look to?
• What degree of technical knowledge should the report assume its audience has?
• What is the most effective way to show information?
• How should the report be organized?
• How should it be designed?
• What tone and level of language difficulty should the document have?

Usage of critical thinking comes down not only to the outline of your paper, it also begs the question: How can we use critical thinking solving problems in our writing's topic?

Let's say, you have a Powerpoint on how critical thinking can reduce poverty in the United States. You'll primarily have to define critical thinking for the viewers, as well as use a lot of critical thinking questions and synonyms to get them to be familiar with your methods and start the thinking process behind it.

5 Interview Questions That Gauge Critical Thinking Skills

• Share to Facebook
• Share to Twitter
• Share to Linkedin

As a job candidate, you're likely to encounter interview questions designed to assess your critical thinking skills. Employers highly value these skills because they demonstrate your ability to analyze information, solve problems creatively, and make sound decisions. In a world filled with AI, an overabundance of data, increasingly rapid decision-making, and greater autonomy with remote work, critical thinking skills are atop employers' lists of desired candidate traits.

Questions That Assess Critical Thinking Skills

Every company will put their own spin of critical thinking interview questions, but here are five of the most common questions that you should be ready to answer:

• Tell me about a time you had to solve a complex problem at work. What was your approach?
• What do you think are the three biggest challenges facing our industry right now? How would you address them?
• Describe a time when you had to make an important decision with limited information or time. How did you handle it?
• Tell me about a time your initial approach to solving a problem didn't work. How did you pivot?
• If you were in charge of our company, what's one major change you would make and why?

The good news with these five questions is that if you construct good answers for each of them, you'll be well-positioned to handle any other variations you come across.

When you're answering critical thinking interview questions, it's vital for you to demonstrate how you analyze situations, assess and solve challenges, and reflect and learn from your experiences. And that's where the SHER Method can be especially helpful.

The SHER Method is a structured approach to answering interview questions that stands for Situation, Hurdle, Endgame, and Reflection. When using this method, you start by briefly describing the Situation or context of the experience you're sharing. Next, you explain the Hurdle or challenge you faced. Then, you detail the Endgame, which includes the actions you took to address the challenge and the results you achieved. Finally, you conclude with a Reflection, sharing what you learned from the experience and how it has influenced your subsequent professional conduct.

The SHER Method is particularly powerful for demonstrating critical thinking skills because it guides candidates to systematically analyze a situation, identify challenges, explain their problem-solving process, and reflect on outcomes and lessons learned. It showcases your ability to think critically and learn from experiences in a structured and compelling way. And that's really the foundation of critical thinking skills.

When answering critical thinking interview questions, keep these points in mind:

• Use specific examples from your experience
• Clearly explain your thought process and reasoning
• Demonstrate a systematic approach to problem-solving
• Show that you consider multiple perspectives
• Emphasize data-driven decision making
• Highlight your ability to adapt and learn from experiences
• Be prepared to discuss both successes and failures
• Show how you've applied lessons learned to future situations

Specific Answers To Critical Thinking Interview Questions

Let's look at some specific answers to some of the aforementioned questions that assess critical thinking skills.

Question 1: Tell me about a time you had to solve a complex problem at work. What was your approach?

Why is this an important question that is often included in interviews? It's because there is no shortage of complex problems that need solving, and when a company is making a big hire, it hopes the candidate has some good solutions.

In your answer, describe the complex problem you faced, explain the main challenges you encountered, detail the steps you took to solve the problem, and share what you learned from the experience.

Here's an example answer: "In my previous role as a project manager, we were tasked with implementing a new software system that would integrate multiple departments. The primary challenge was significant resistance to change from each department. I started by mapping out all the current processes and identifying areas of overlap. Then, I conducted interviews with key stakeholders from each department to understand their specific needs and concerns. Using this information, I created a phased implementation plan that addressed each department's unique requirements while still achieving our overall integration goals. This experience taught me the importance of stakeholder engagement in managing complex changes. I've since incorporated regular cross-departmental meetings into all my projects to ensure alignment and address concerns proactively."

Question 2: What do you think are the three biggest challenges facing our industry right now? How would you address them?

Why is this an important question that is often included in interviews? Simply put, it evaluates your strategic thinking and industry knowledge. If you're interviewing somewhere that prioritizes industry veterans, this question is quite common.

In your response, acknowledge the current state of the industry, identify three specific challenges, propose solutions for each challenge, and conclude with a forward-looking statement.

Here's an example answer: "The [specific] industry is currently facing significant disruption due to technological advancements, changing consumer behaviors, and regulatory pressures. The three biggest challenges I see are: 1) Adapting to rapidly evolving technology, 2) Meeting increasing customer demands for personalization, and 3) Navigating complex regulatory environments. To address these challenges, I would: 1) Implement a continuous learning program to keep our team updated on the latest technologies, 2) Invest in data analytics to better understand and predict customer preferences, and 3) Establish a dedicated regulatory compliance team to ensure we stay ahead of legal requirements. These challenges also present opportunities for companies that can adapt quickly. By addressing them proactively, we can position ourselves as industry leaders."

Question 3: Describe a time when you had to make an important decision with limited information or time. How did you handle it?

This question assesses your decision-making skills under pressure, which are relevant to lots of companies these days. In your answer, set the scene, explain the constraints you faced, detail your decision-making process, and share the outcome and lessons learned.

For example: "During a critical product launch, we discovered a potential safety issue just 24 hours before the scheduled release. We had limited time to gather information and make a decision, and any delay would result in significant financial losses. I quickly assembled a cross-functional team including engineering, legal, and marketing. We conducted a rapid risk assessment, weighing the potential safety concerns against the impact of delaying the launch. Based on our analysis, we decided to postpone the launch by one week to thoroughly address the safety issue. This decision ultimately saved us from potential legal issues and reputational damage. It reinforced for me the importance of prioritizing safety and quality over short-term gains, and the value of having a diverse team for rapid problem-solving."

Demonstrate Critical Thinking Skills Through Your Answers

Remember that when companies ask about critical thinking skills, they're not just looking for the correct answer but for insight into how you think and approach challenges. By demonstrating your ability to analyze situations, overcome obstacles, implement solutions, and learn from outcomes, you'll position yourself as someone who exercises critical thinking skills all day, every day.

What Is Creative Thinking? Definition, Examples, and How to Showcase It During Your Job Search

Have you ever whipped up a delicious meal using random leftover ingredients? That silly example, friends, is creative thinking in action. In today's job market, where innovation is key, creative thinking is no longer just a bonus skill—it's a must-have.

But what exactly is the creative thinking definition? Why is creative thinking a good skill ? How can you showcase it to potential employers? We’ve got all the answers.

What is creative thinking?

Creative thinking is the ability to look at problems or situations from a fresh perspective. It involves thinking outside the box and coming up with unique, effective solutions. This skill is not limited to artistic fields but is essential in every profession, from business and science to technology and education. (Here are five ways to inject creativity into every single job —even ones that involve numbers.)

A creative thinker is someone who can adapt to changing circumstances and come up with original solutions. It's someone who’s curious, who asks questions and isn't afraid to try new things. They can see possibilities where others might see limitations, and they find joy in the process of exploration and discovery.

Four different types of creative thinking

Creative thinking comes in various forms, each valuable in different contexts. Here are some key types of creative thinking:

1. Artistic creativity

This is likely the one that springs to mind first—it’s the ability to create something new and beautiful, whether it's a painting, a song, a book, or a well-designed website. Artistic creativity is crucial in fields like graphic design , advertising, and entertainment, where visual and auditory appeal play significant roles.

2. Analytical creativity

Analytical creativity is all about breaking down complex problems and finding innovative solutions through data, information, and logical thinking. It’s essential in fields like data science, engineering, and finance , where identifying patterns and making data-driven decisions can lead to significant advancements.

3. Lateral thinking

Lateral thinking involves looking at a problem from different angles and finding solutions that aren’t immediately obvious. This type of thinking is super important in roles that require problem-solving and innovation, such as product development, marketing, and management. It encourages thinking outside the box and finding creative ways to overcome challenges.

4. Divergent and convergent thinking

Divergent thinking is brainstorming a wide range of ideas, no matter how crazy and unusual they might seem at first. Convergent thinking, on the other hand, involves narrowing down these ideas to find the best possible solution. Both types are important in the creative process: divergent thinking sparks innovation, while convergent thinking refines and implements the ideas.

Examples of creative thinking

Now that we've explored the different types of creative thinking, let's see how these skills manifest:

Open-mindedness

This is the foundation of creative thinking. It's about being receptive to new ideas and new perspectives, even if they seem unconventional at first. For instance, in a team meeting, being open-minded might mean considering unconventional suggestions and exploring their potential before dismissing them.

Innovation and invention

Innovation involves creating new ideas, products, or methods, while invention is about bringing those ideas to life. Thinking creatively can be an asset in environments that encourage experimentation and risk-taking. An engineer who designs a groundbreaking app is a good example of this type of creative thinking.

Problem-solving

Problem-solving is a key aspect of creative thinking. It’s the ability to define a problem, create original solutions, and implement the best one. A project manager who overcomes a significant challenge by following a unique approach is showcasing creative problem-solving skills.

Collaborative thinking

Collaborative thinking involves working with others to generate and refine ideas. It requires communication, empathy, and the ability to build on others' input. For example, a creative thinker might lead a brainstorming session where team members feel encouraged to share their ideas, resulting in a collective, innovative solution.

Bonus tips to embrace your creative side

The more you learn, including outside your work environment, the more fodder you'll have for creative thinking. Take a look at these tips:

• Challenge yourself: Step outside your comfort zone! Try new hobbies , learn a new language, or a new instrument, or take a different route to work. Exposing yourself to new experiences sparks fresh ideas and helps you see the world from different perspectives.
• Embrace curiosity: Curiosity is the fuel that ignites creativity. Ask questions, explore different ideas, and be open to new information. Read books outside your usual genre, watch documentaries on unfamiliar topics, or start conversations with people from different backgrounds.
• Brainstorm like a boss: Sometimes the best ideas come from collaboration. Use brainstorming techniques like mind maps or group brainstorming sessions to generate a wide range of ideas. Don't be afraid to get a little silly—even weird ideas can spark something truly innovative.
• Turn obstacles into catalysts: Believe it or not, limitations can actually boost creativity . Think of a time you had to come up with a presentation using only 5 or 10 minutes. This challenge can force you to create unexpected solutions. So, the next time you face a constraint, see it as an opportunity to unleash your creative potential!

How to highlight your creative thinking during a job search

Employers look for creative thinkers because they can communicate ideas clearly and solve problems effectively. Now that you know the definition for creative thinking and its several types, it’s time to show you how to make this creative side stand out in your job search.

On your resume

When updating your resume , emphasize any creative projects or achievements. Detail the innovative solutions you've implemented and the impact they had. If you developed a new process that increased efficiency or created a marketing campaign that boosted engagement, these are perfect examples of creative thinking skills on a resume.

Using strong action verbs can make these contributions stand out. Try to use words like:

In your cover letter

Your cover letter is a great place to dive into specific examples of creative problem-solving. Describe situations where you faced a challenge and how a creative thought helped overcome them. If you found a unique way to market a product or solve a logistical issue, for example, these stories highlight your ability to think creatively.

It’s also important to personalize your cover letter to the job you're applying for by linking your creative thinking skills to the company's needs and goals. Explain how your ability to think creatively aligns with the job requirements and can help the company achieve its goals.

During interviews

In interviews , be ready to give concrete examples of your creative thinking in action. Discuss past experiences where your innovative ideas led to successful outcomes. Whether it was developing a new strategy, solving a complex problem, or improving a process, these examples will show your creative side.

Prepare to answer behavioral questions—those designed to evaluate how you handle some situations—with stories that highlight your creative problem-solving abilities. For example, if asked about a time you faced a significant challenge, describe how you used creativity and creative thinking to navigate the situation and achieve a positive result.

One thing that makes large language models (LLMs) so powerful is the diversity of tasks to which they can be applied. The same machine-learning model that can help a graduate student draft an email could also aid a clinician in diagnosing cancer.

However, the wide applicability of these models also makes them challenging to evaluate in a systematic way. It would be impossible to create a benchmark dataset to test a model on every type of question it can be asked.

In a new paper , MIT researchers took a different approach. They argue that, because humans decide when to deploy large language models, evaluating a model requires an understanding of how people form beliefs about its capabilities.

For example, the graduate student must decide whether the model could be helpful in drafting a particular email, and the clinician must determine which cases would be best to consult the model on.

Building off this idea, the researchers created a framework to evaluate an LLM based on its alignment with a human’s beliefs about how it will perform on a certain task.

They introduce a human generalization function — a model of how people update their beliefs about an LLM’s capabilities after interacting with it. Then, they evaluate how aligned LLMs are with this human generalization function.

Their results indicate that when models are misaligned with the human generalization function, a user could be overconfident or underconfident about where to deploy it, which might cause the model to fail unexpectedly. Furthermore, due to this misalignment, more capable models tend to perform worse than smaller models in high-stakes situations.

“These tools are exciting because they are general-purpose, but because they are general-purpose, they will be collaborating with people, so we have to take the human in the loop into account,” says study co-author Ashesh Rambachan, assistant professor of economics and a principal investigator in the Laboratory for Information and Decision Systems (LIDS).

Rambachan is joined on the paper by lead author Keyon Vafa, a postdoc at Harvard University; and Sendhil Mullainathan, an MIT professor in the departments of Electrical Engineering and Computer Science and of Economics, and a member of LIDS. The research will be presented at the International Conference on Machine Learning.

Human generalization

As we interact with other people, we form beliefs about what we think they do and do not know. For instance, if your friend is finicky about correcting people’s grammar, you might generalize and think they would also excel at sentence construction, even though you’ve never asked them questions about sentence construction.

“Language models often seem so human. We wanted to illustrate that this force of human generalization is also present in how people form beliefs about language models,” Rambachan says.

As a starting point, the researchers formally defined the human generalization function, which involves asking questions, observing how a person or LLM responds, and then making inferences about how that person or model would respond to related questions.

If someone sees that an LLM can correctly answer questions about matrix inversion, they might also assume it can ace questions about simple arithmetic. A model that is misaligned with this function — one that doesn’t perform well on questions a human expects it to answer correctly — could fail when deployed.

With that formal definition in hand, the researchers designed a survey to measure how people generalize when they interact with LLMs and other people.

They showed survey participants questions that a person or LLM got right or wrong and then asked if they thought that person or LLM would answer a related question correctly. Through the survey, they generated a dataset of nearly 19,000 examples of how humans generalize about LLM performance across 79 diverse tasks.

Measuring misalignment

They found that participants did quite well when asked whether a human who got one question right would answer a related question right, but they were much worse at generalizing about the performance of LLMs.

“Human generalization gets applied to language models, but that breaks down because these language models don’t actually show patterns of expertise like people would,” Rambachan says.

People were also more likely to update their beliefs about an LLM when it answered questions incorrectly than when it got questions right. They also tended to believe that LLM performance on simple questions would have little bearing on its performance on more complex questions.

In situations where people put more weight on incorrect responses, simpler models outperformed very large models like GPT-4.

“Language models that get better can almost trick people into thinking they will perform well on related questions when, in actuality, they don’t,” he says.

One possible explanation for why humans are worse at generalizing for LLMs could come from their novelty — people have far less experience interacting with LLMs than with other people.

“Moving forward, it is possible that we may get better just by virtue of interacting with language models more,” he says.

To this end, the researchers want to conduct additional studies of how people’s beliefs about LLMs evolve over time as they interact with a model. They also want to explore how human generalization could be incorporated into the development of LLMs.

“When we are training these algorithms in the first place, or trying to update them with human feedback, we need to account for the human generalization function in how we think about measuring performance,” he says.

In the meanwhile, the researchers hope their dataset could be used a benchmark to compare how LLMs perform related to the human generalization function, which could help improve the performance of models deployed in real-world situations.

“To me, the contribution of the paper is twofold. The first is practical: The paper uncovers a critical issue with deploying LLMs for general consumer use. If people don’t have the right understanding of when LLMs will be accurate and when they will fail, then they will be more likely to see mistakes and perhaps be discouraged from further use. This highlights the issue of aligning the models with people's understanding of generalization,” says Alex Imas, professor of behavioral science and economics at the University of Chicago’s Booth School of Business, who was not involved with this work. “The second contribution is more fundamental: The lack of generalization to expected problems and domains helps in getting a better picture of what the models are doing when they get a problem ‘correct.’ It provides a test of whether LLMs ‘understand’ the problem they are solving.”

This research was funded, in part, by the Harvard Data Science Initiative and the Center for Applied AI at the University of Chicago Booth School of Business.

Paris Olympics organizers apologize after critics say 'The Last Supper' was mocked

Paris Olympic organizers apologized Sunday to people offended during a tableau of the opening ceremony that depicted the Greek god Dionysus and an ancient festival meant to honor him. Critics said it mocked “The Last Supper.”

During Friday's ceremony, there was a moment on the Debilly Bridge over the Seine when the camera cut to French DJ and producer Barbara Butch, who describes herself as a "love activist." Butch wore a blue dress with a silver headdress and as the camera panned out, she was flanked by drag queens on both sides. Later appeared a nearly naked man painted in blue − a portrayal of Dionysus, the god of wine-making, vegetation, fertility and ecstasy − on a dinner plate surrounded by food. He then sang as the people around him danced, and it turned into a runway scene where models walked across.

The scene has been met with backlash as people say it mocked "The Last Supper," the famous painting from Leonardo da Vinci that shows Jesus Christ with his 12 apostles at his last supper, where he announced that one of the apostles would betray him.

Several Christian and Catholic organizations around the world have denounced the moment since then. The French Bishops’ Conference, which represents the country's Catholic bishops, said in a statement that the scene was a "mockery and derision of Christianity" and it was thinking of religious followers who were "hurt by the outrageousness and provocation of certain scenes." Well-known Bishop Robert Barron in Minnesota  said in a video that it mocked "a very central moment in Christianity."

U.S. Speaker of the House Mike Johnson said on social media that it was "shocking and insulting" to Christian people.

Telecommunications provider C Spire also said it was pulling all of its advertising from the Olympics as a result of the scene.

What did Paris Olympic organizers say about controversial segment?

Thomas Jolly, the opening ceremony’s artistic director, said at  the International Olympic Committee's daily briefing at the Olympic Games on Saturday that the moment was not meant to "be subversive or shock people or mock people." During the opening ceremony, the official Olympic Games social media account said the blue person, played by French singer and actor Philippe Katerine, was Dionysus and it "makes us aware of the absurdity of violence between human beings."

Jolly also said on French TV station BFMTV on Sunday , "The Last Supper" was "not my inspiration" for the segment, and he also spoke about the meaning of Dionysus.

"The idea was to have a pagan celebration connected to the gods of Olympus. You will never find in me a desire to mock and denigrate anyone," he said.

Still, Paris 2024 spokesperson Anne Descamps apologized on Sunday for those offended by the scene.

"Clearly there was never an intention to show disrespect to any religious group. On the contrary, I think (with) Thomas Jolly, we really did try to celebrate community tolerance," Descamps said. “Looking at the result of the polls that we shared, we believe that this ambition was achieved. If people have taken any offense, we are, of course, really, really sorry.”

The IOC said on social media that it took note of the apology from Paris 2024.
