3.1 Types of Thinking

Learning objectives.

• Understand that there are different types of thinking.
• Identify how each type of thinking contributes to learning.

So what are the various types of thinking skills, and what kind things are we doing when we apply them? In the 1950s, Benjamin Bloom developed a classification of thinking skills that is still helpful today; it is known as Bloom’s taxonomy . He lists six types of thinking skills, ranked in order of complexity: knowledge, comprehension, application, analysis, synthesis, and evaluation. Figure 3.2 “Types of Thinking Skills” outlines each skill and what is involved in that type of thinking, as updated by Lorin Anderson and David Krothwohl.

All of these thinking skills are important for college work (and life in the “real world,” too). You’ve likely had a great deal of experience with the lower-level thinking skills (yellow section). The midlevel skills are skills you will get a lot of practice with in college, and you may be well on your way to mastering them already. The higher-level thinking skills (red section) are the most demanding, and you will need to invest focused effort to develop them.

Exercise: Thought Inventory

Think about Figure 3.2 “Types of Thinking Skills” . Are you using all six thinking skills? Reflect on your schoolwork in the past three weeks and identify specific examples where you used each of the thinking skills. Use the comment column to write notes about the skills that are second nature to you and those you would like to develop further.

Look at the lists of things you actually did in each case. Notice that there are certain verbs that apply to each skill set. When you see those verbs as a prompt in an assignment or an exam, you will know what kind of thinking the instructor expects from you. Table 3.1 “Thinking Verbs” lists some of the most common verbs associated with each thinking skill.

Table 3.1 Thinking Verbs

Throughout this book, we give tips that will help you develop your thinking skills. You have read about the learning cycle and the importance of applying your knowledge. You will learn tips for remembering information from your notes and classes. Preparing for class requires you to analyze what you know and what you need to learn. The sections on listening and reading will help you develop your understanding skills. Look for those tips and practice them.

In this chapter, we will focus on critical thinking (evaluating) and creative thinking. They deserve specific focus because they are likely to be the skills you have least practice with. These are the skills most helpful for success in college and in “real life.” Creative thinking will help you come up with possible solutions for problems and new ideas. Critical thinking will help you decide which of those ideas have most merit and deserve to be implemented.

Key Takeaways

• We use different types of thinking skills to address different requirements, and these skills are classified in Bloom’s taxonomy.
• You have been using many thinking skills since childhood.
• Two very important thinking skills you will need to develop for success in college and in life are critical (or evaluative) thinking and creative thinking.

7 Types of Critical Thinking: A Guide to Analyzing Problems

Critical thinking is the ability to think clearly and rationally about various issues and situations. It involves applying different types of thinking skills to different problems and challenges. Some of the main types of critical thinking are: Analytical Thinking, Creative Thinking, Decision-Making, Problem-Solving, Reflection , Open-mindedness, Good communication

Have you ever had a problem that was too big to solve right away? Or perhaps you just couldn’t figure out how to approach it? Whether it’s a personal, academic, or professional problem, having the right set of critical thinking skills can help.

Critical thinking is all about carefully evaluating data and making rational decisions. In other words, it’s the skill of analyzing information from many different points of view before drawing a conclusion. It’s an ongoing process that involves gathering information, asking questions, and considering various solutions.

In this guide, we’ll go over different types of critical thinking skills and provide examples of how to apply these skills when approaching a problem from any angle. We’ll also look at ways to sharpen your critical thinking skills so you can tackle any challenge with ease. So let’s get started.

Table of Contents

What is “critical thinking”.

Critical thinking is the ability to analyze a problem or situation and come up with a rational, informed solution. It’s an essential skill for all kinds of processes, from problem solving to decision-making to creative thinking.

In order to tackle complex problems, you need to be able to think critically and evaluate the information at your disposal in order to come up with the best solution.

Critical thinking involves breaking down a problem into its component parts and analyzing it systematically to determine how best to proceed. It requires the ability to think objectively and make informed judgments based on facts and evidence rather than just guesswork or opinion. It also involves the use of several different types of critical thinking skills, such as:

• Analytical Thinking : This type of critical thinking skill involves analyzing data or information in order to draw logical conclusions or find solutions. It’s important for problem-solving and decision-making since it helps you find solutions through careful analysis.
• Creative Thinking: This type of critical thinking skill requires imagination and open-mindedness in order to come up with innovative ideas and solutions. It can help you identify new ways of looking at a situation or find different solutions to a problem.
• Problem-Solving Thinking : This type of critical thinking skill involves developing strategies in order to solve problems quickly and effectively.

Different Types of Critical Thinking

Critical thinking involves analyzing and evaluating information in order to come to a conclusion or make decisions. But did you know that there are different types of critical thinking?

Let’s break down those types of critical thinking skills into 7 different titles and learn them one by one:

1. Analytical Thinking

It is all about taking the pieces of a problem, digging into them, and methodically finding a solution. Analytical thinking is a key element in working through problems and coming up with the best plan of action for success.

So, what does analytical thinking involve? It involves being able to break a problem down into smaller bits and pieces, understanding how each piece interconnects, and developing strategies for solving each individual piece by gathering information relating to it.

Analyzing how each piece of the puzzle affects the next requires you to really understand how they connect together, and using this approach can help you come up with better solutions that can help improve the overall situation.

You’ll also need to make sure any strategies or solutions you come up with are grounded in evidence-based research so that your conclusions are reliable.

Here are some key skills necessary for effective analytical thinking:

• Evaluating: being able to review facts and make judgments about them depending on the situation at hand
• Investigating means asking questions about various aspects of a problem and doing research so that you can identify its root causes.
• Synthesizing: Combining different pieces of data or information together to create new solutions or approaches to existing problems
• Reasoning logically means connecting bits of data together in order to evaluate different possibilities that could help solve the problem or issue at hand.

With these analytical thinking skills, you can start breaking down any problem into smaller, manageable parts, think logically through how they connect together, assess what evidence is needed to make decisions, and draw conclusions based on facts rather than just opinions or hunches.

2. Creative Thinking and Idea Generation

Do you ever feel like your thoughts are stuck in a rut ? Creative thinking and idea generation can help you come up with fresh solutions to problems and break out of that rut.

Creative thinking is an essential critical thinking tool. It can help you look at an issue from a different point of view or think of new ways to approach the problem. Here are some tips for giving your creative thinking skills an extra boost:

• Challenge assumptions.    Even if something seems obvious, take some time to question it and consider other possibilities.
• Brainstorm different solutions . Try writing down potential solutions, no matter how wild they may seem, then look for patterns between them or ideas that can be combined into something new.
• Consider different perspectives. Even if the issue seems cut and dry from one perspective, try to imagine it from other angles and think about how the issue appears from those views.
• Take a break and come back later with fresh eyes: sometimes taking a step away from the problem is enough to give you the necessary distance to discover new ideas or paths of exploration.

These strategies will help dramatically improve your ability to generate new ideas and jumpstart your creative thinking process whenever you need it.

3. Decision-Making

When it comes to critical thinking, decision-making is an essential skill. It’s not just about being able to evaluate a situation; it’s about being able to make a well-informed decision that will bring the best results.

Here are four key components of decision-making:

• Goal Setting : Take time to first identify what you want to accomplish with your decision.
• Analyzing Alternatives: Evaluate the pros and cons of potential solutions before choosing one.
• Risk assessment: estimate the possible risks associated with each potential solution, based on current evidence.
• Implementation: Once the decision is made, start working on implementation tasks and track results for ongoing improvement or refinement.

By following these steps, you’ll be in a better position to make decisions that have positive outcomes for you and those involved in the decision-making process.

The ability to think critically and make sound decisions can not only help you solve problems quickly but can also lead to more successful long-term strategies for your business or organization.

4. Problem-Solving

It is one of the most essential types of critical thinking skills. Problem-solving involves taking all the pieces of a problem and figuring out how to resolve it. This can involve coming up with new solutions, making decisions, devising strategies, and identifying patterns and trends.

It’s an invaluable skill in many aspects of life and can help you create effective solutions to a wide range of problems. To use your problem-solving skills effectively, keep these tips in mind:

• Break the problem down into smaller, manageable parts . Breaking down a problem into smaller chunks makes it easier to work on and understand.
• Look for connections between pieces. Try to identify any connections between different aspects or pieces of the problem to gain insights that may help you solve it more efficiently.
• Don’t get overwhelmed by the scope of the challenge at hand; take it one step at a time and remember that even small victories can help move you closer to finding a solution.
• Think creatively when coming up with possible solutions or strategies; often the best solution is not obvious at first glance.
• Keep track of what works and what doesn’t ; this will give you valuable insights for future problem-solving endeavors as well as feedback on your progress towards resolving the current one at hand.

5. Reflection and Assessing Evidence

Now it’s time to take a look at your own cognitive activity. Reflection and assessing evidence are two types of critical thinking skills that help you make sure you’re not jumping to conclusions without considering the pros and cons of a situation.

When it comes to reflection, this involves being honest with yourself and taking a deep look at the way your thoughts, feelings, and beliefs are informing your decisions. At its core, reflection allows you to objectively evaluate the evidence that’s in front of you so that you can make an informed assessment about what the best next step is for a given problem or situation.

Assessing evidence is also critical for coming up with effective solutions. This means carefully examining the available data and making sure you have all of the necessary information before reaching an opinion or making a decision. It involves looking at multiple perspectives and interpretations of any given issue so that you can form an educated conclusion about how best to solve it.

6. Open-mindedness

It is a critical thinking skill that is all about trying to understand something from different perspectives and being able to appreciate the difference in opinions. Open-mindedness allows you to analyze a problem from multiple angles and consider different solutions or ways of approaching it.

Here are some tips for developing open-mindedness as a critical thinking skill:

• Listen carefully and actively to others ; rather than just hearing words, try to understand their point of view.
• Ask questions without judgmen t and without assuming your own opinion is the right one.
• Pay attention to how other people view the same situation differently than you do.
• Think critically and evaluate arguments objectively, without assumptions or preconceived ideas about what the answer should be or which course of action should be taken.
• Suspend judgment until you have enough information about a topic or situation; don’t jump to conclusions too quickly.
• Prioritize respect when engaging with others who have different perspectives. Be willing to put in the effort required to understand why they think that way and why that might be important to them in their lives or work.
• Avoid making assumptions about what someone else believes; find out more first before passing judgment on someone’s opinion or actions.

By developing this type of open-mindedness, you can become more aware of how your personal biases may impact your ability to think critically, improving your overall decision-making skills over time and helping you become a more valuable asset as part of any team or organization.

7. Good communication

Good communication is an important part of the critical thinking process. That’s because having good communication skills helps you be more persuasive, helping you convince people of ideas and solutions that are well thought-out. It also allows you to better explain and justify your reasoning to others, which is essential when looking at complex problems.

To have strong communication skills, it’s important to think before you speak. You should also take the time to clearly articulate your thoughts, using simple yet powerful language. Additionally, having an open mind is key. It allows you to consider different angles and perspectives on any issue or problem that you might face.

Here are some tips for good communication:

• Take a moment to succinctly formulate your thoughts before speaking or writing them down.
• Ask questions when necessary, and listen carefully to what others have to say.
• Stay open-minded in conversations, as this will help broaden your knowledge of the situation.
• Speak clearly and use accurate language so that your message won’t be misunderstood.

While it’s true that critical thinking skills can’t be taught in just a few days, plenty of work and practice can go a long way toward equipping you to think critically about the problems in your life. With the right practice and guidance, you can become a master at analyzing issues, discerning cause and effect, and integrating facts to formulate your strategy.

If you’re looking to hone your critical thinking skills, start by breaking down a problem into its component parts. Assess the evidence, identify assumptions, and determine the best course of action. With practice and dedication, you can develop the analytical skills to resolve complex problems and make better decisions in the future.

The 4 Types of Critical Thinking Skills – Explained!

Chris Drew (PhD)

Dr. Chris Drew is the founder of the Helpful Professor. He holds a PhD in education and has published over 20 articles in scholarly journals. He is the former editor of the Journal of Learning Development in Higher Education. [Image Descriptor: Photo of Chris]

Learn about our Editorial Process

Critical thinking skills are the mental process involved in processing information. They help us with problem solving, decision making, and thinking critically.

There are four types of “thinking skills”: convergent or analytical thinking , divergent thinking, critical thinking and creative thinking. We use these skills to help us understand the world around us, think critically, solve problems, make logical choices and develop our own values and beliefs.

The 4 Types of Thinking Skills

The 4 types of thinking skills are:

1. Convergent Analytical Thinking

Convergent thinking is the process of coming up with the best answer to a question using our memory, resources around us, or logic.

This thinking skill does not require significant creativity or lateral thinking strategies . It is not the best for solving problems that are complex or require thinking out of the box. Instead, it uses very straightforward thought processes. A convergent thinker simply needs to apply already established procedures and memory recall to reach the ‘correct’ answer.

Convergent thinking is very commonly used for standardized and multiple choice tests. These sorts of tests simply assess our knowledge and ability to apply knowledge to simple and logical situations.

The key elements required to be a skilled convergent thinker are: speed, accuracy and logic.

2. Divergent Thinking

Divergent thinking is the exact opposite of convergent thinking. It involves coming up to solutions, paths forward or new ideas when there is no single correct answer.

Questions like “should I study to become a doctor or a lawyer?” may not have a simple answer. You might be good at both, and both options might bring you happiness and a good life. So, which option should you choose?

To come up with solutions to questions without clear answers, you need to break down the possibilities and analyze each part. You might create a pros and cons list, a Venn diagram or a table to lay out your options and consider each one in turn.

We often encourage divergent thinking from a very young age. For example, we encourage children to play or simply ‘be playful’ in order to solve problems and discover how their world is complex and full of possibility.

3. Critical Thinking Skills

Critical thinking skills involve analyzing something in order to form a judgement about it.

A critical thinker does not take the assumptions of a topic for granted. Instead, the critical thinking involves ‘critiquing’ what your are viewing using your available intellectual knowledge.

People who think critically can use three processes to develop critical insights on a topic: deduction, induction and abduction.

Deduction includes the critical thinking skills that involve drawing conclusions based on the facts at hand. You have all the facts available to you to come to a clear and unambiguous conclusion about a topic. For example, a doctor does blood tests to determine if someone has a virus. The blood tests come back positive, so we can deduce that you definitely have that virus. Deduction is a great skill to use if you want to solve problems.

Induction includes the critical thinking skills that involve drawing conclusions based on a generalization . You don’t have all the exact information at hand. However, you think critically and realize are aware of patterns, clues and a methodology that can help you induce the answer. For example, you come to the doctor exhibiting a fever, sneezing and coughing. The doctor doesn’t do tests, but they induce that you probably have influenza because your symptoms are characteristic of someone with the flu.

Abduction includes the critical thinking skills that involve coming to a conclusion that is the most likely or logical based on the small amount of knowledge that you have. You can’t be sure of the answer, but you can think critically and make an educated guess. For example, you may see that a cat is on the roof. The most logical answer is that the cat got up there by climbing a nearby tree and jumping from it to the roof, but you can’t be sure.

Read about more examples of critical thinking on our full write-up.

4. Creative Thinking

Creative thinking involves thinking about a topic in unusual, unconventional and alternative ways to generate new ideas about an established topic. A creative thinker will try to address an issue from a perspective that hasn’t been used before.

While creative thinking may appear illogical, it is in fact a great driver of human development. Creative thinkers identify gaps in marketplaces or new, easier, faster and better ways of doing things. When a creative thinker comes up with a great new way of approaching an issue, their new method can become the new orthodoxy.

How to Maintain your Thinking when School is Over

You need to keep your mind active in order to maintain improve your critical thinking skills.

When I finished high school, I stopped thinking mathematically . I stopped using calculus, trigonometry, geometry, etc. in my daily life. Ten years on, my critical thinking skills that involve mathematics are very poor.

By contrast, I kept reading and writing in the ten years since graduating high school. I am much better at these creative and critical thinking skills than I was when I was at high school. That’s because I continued to exercise those creative and critical thinking skills aspects of my mind on a regular basis.

Some ways to maintain your mind’s neural pathways and keep up strong critical thinking skills include:

• Doing Sudoku quizzes daily
• Doing Crosswords daily
• Reading a book per month
• Completing mathematical quizzes regularly
• Taking courses in community college
• Doing brain exercise apps focused on critical thinking

How to Improve your Critical Thinking Skills

To improve your critical thinking skills, you need to go beyond just maintaining your mind.

You cannot just keep doing the same thing day-in, day-out and expect to get better. Critical thinkers are always working on self-improvement.

Instead, you need to exercise new parts of your brain by studying regularly and keep creating new neural pathways in your mind. This emphasizes the importance of education for critical thinking.

You always need to be thinking about things that are new and difficult for you to understand.

The things that you learn need to be difficult. It’s through the difficulty and discomfort in thinking that you are improving your critical thinking and problem solving skills. It’s just like going to the gym: no pain, no gain.

Some ways to improve your critical thinking skills include:

• Taking college courses (or one of these alternatives ) in topics that you find very difficult
• Taking classes in an online school
• Learning using new learning strategies that make you uncomfortable
• Taking up new and diverse hobbies

The more you think, the better you will get at being a critical thinkers. You’ll become faster, more creative and overall better at thinking if you practice and try out new strategies.

Tools to Help you Think Better

There are also some tools that we call cognitive tools that help you with your critical thinking skills. These tools don’t do the thinking for you, but they help you to become a good critical thinker.

Thinking tools can help critical thinkers include:

• Helping you structure your thoughts
• Giving you a blueprint or scaffold for finding new angles to approach a topic
• Providing prompts to move your thinking forward

Some tools that can help your thinking skills include:

1. A Brainstorming Mind Map

A brainstorming mind map can be made with a simple piece of paper. Simply write the topic at the top of the piece of paper and scrawl any and all key things you can think about down onto the paper. During the brainstorming process , no ideas are bad ideas. You can use critical thinking to critique and dismiss some of your ideas later on; but the brainstorming session can help get your mind moving and exercise those critical thinking skills.

2. A Radar Chart

A radar (or spider) chart is very similar to a brainstorming mind map, but it also shows the links between concepts.

To create a spider chart , write the topic you’re thinking about in the middle of the piece of paper.

When you come up with a new idea, write it near the middle of the paper and draw a line from the topic in the center to the idea. If you come up with new ideas or sub-ideas based on that first key idea, you can write them down and draw a line from one idea to the other. Whenever you come up with related ideas, you should draw a line between them to show their relationship.

3. A Process Chart

A process chart shows the sequence of steps from a question to its logical answer. Often in science and mathematics classes, you need to provide your process chart to your teacher to show how you came to your conclusions . You may hear your teacher tell you to “show your critical thinking skills”!

4. A Spreadsheet

Even a simple spreadsheet using Excel or Google Sheets can help with your critical thinking. It will help you lay out ideas into an easy-to-read table to help you keep track of your thoughts, your processes and your different categories. Categorizing ideas into columns and rows can help you to identify new patterns in data.

5. A Pros and Cons List

A simple pros and cons list can help you to get your ideas out of your brain and onto paper. Once it’s on paper, you can go through the list systematically and compare the pros and cons directly with one another. Once you’ve done this, you may have a better idea of what conclusions to come to.

6. De Bono’s Six Thinking Hats

Another strategy for helping your thinking skills is to use De Bono’s Six Thinking Hats. These are six metaphorical ‘hats’ that you can put on. Each hat represents a different way to look at a topic. When you ‘put the hat on’, you have to think from the perspective of the hat. These hats are great for your critical thinking.

The six hats are:

• Red Hat: Think about your feelings, emotions and hunches about a topic
• White Hat: Think about the information that’s available to you and what it can reveal about the topic
• Yellow Hat: Think about the benefits and value in the situation you’re thinking about.
• Black Hat: Think about the risks, difficulties and challenges that a situation you’re thinking about may cause.
• Green Hat: Think about the alternatives and creative approaches you can apply to a topic.
• Blue Hat: Think about the processes you can use and how to manage the situation logically.

Final Thoughts

Thinking skills are necessary for problem solving, decision making, and thinking critically. They help you do your job better, make smart decisions, and improve your own life. You can classify your thinking skills into: convergent thinking, divergent thinking, critical thinking, and creative skills. You could also use strategies such as De Bono’s thinking hats, a pros and cons list or a process chart to help you think .

Make sure you keep your mind active, try new things and do quizzes to maintain your thinking skills throughout your life.

3 thoughts on “The 4 Types of Critical Thinking Skills – Explained!”

Professor Chris,    I have a question. As you outline, “There are four types of ‘thinking skills'”.

1. convergent or analytical thinking, 2. divergent thinking, 3. critical thinking and 4. creative thinking. 

   All four are processes of “thinking”.  This leads me to ask, “What is the description of the process of thinking?”

  W. Edwards Deming,  American engineer, statistician and professor observed:

   ”If you can’t describe what you are doing as a process, you don’t know what you are doing.”

   If we can’t describe thinking as a specific  process, we don’t know what we are doing.  

   Without knowing the  specific process of thinking, we don’t know how to perform: analytical thinking, divergent thinking, critical thinking or creative thinking. 

   I repeat my question. “What is the description of the process of thinking?” Thank you for your time, Ted

Definitions are such tricky things! It’s hard to find consensus in the scholarly community about a simple definition of anything, really. Although, I’d agree on the face of it that thinking is a process (and the knowledge or idea is the product). You might be interested in the concept of process thinking , which we often juxtapose to systems thinking (which, really, also involves ‘thinking as a process’), but as you have teased out this fact that thinking is inevitably a process, I wanted to give you a nudge to a resource that’ll help you go deeper on the topic.

All the best! Chris

This is interesting! Learning these four types of thinking skills would definitely help me with either school or work.

3.1 Types of Thinking

Learning objectives.

• Understand that there are different types of thinking.
• Identify how each type of thinking contributes to learning.

So what are the various types of thinking skills, and what kind things are we doing when we apply them? In the 1950s, Benjamin Bloom developed a classification of thinking skills that is still helpful today; it is known as Bloom’s taxonomy A classification of thinking skills developed by Benjamin Bloom. In order of increasing complexity, they are knowledge, comprehension, application, analysis, synthesis, and evaluation. . He lists six types of thinking skills, ranked in order of complexity: knowledge, comprehension, application, analysis, synthesis, and evaluation. Figure 3.2 "Types of Thinking Skills" outlines each skill and what is involved in that type of thinking, as updated by Lorin Anderson and David Krothwohl. L. W. Anderson and David R. Krathwohl, eds., A Taxonomy for Learning, Teaching, and Assessing: A Revision of Bloom’s Taxonomy of Educational Objectives (Boston, MA: Allyn & Bacon, 2001).

Figure 3.2 Types of Thinking Skills

All of these thinking skills are important for college work (and life in the “real world,” too). You’ve likely had a great deal of experience with the lower-level thinking skills (yellow section). The midlevel skills are skills you will get a lot of practice with in college, and you may be well on your way to mastering them already. The higher-level thinking skills (red section) are the most demanding, and you will need to invest focused effort to develop them.

Exercise: Thought Inventory

Think about Figure 3.2 "Types of Thinking Skills" . Are you using all six thinking skills? Reflect on your schoolwork in the past three weeks and identify specific examples where you used each of the thinking skills. Use the comment column to write notes about the skills that are second nature to you and those you would like to develop further.

Look at the lists of things you actually did in each case. Notice that there are certain verbs that apply to each skill set. When you see those verbs as a prompt in an assignment or an exam, you will know what kind of thinking the instructor expects from you. Table 3.1 "Thinking Verbs" lists some of the most common verbs associated with each thinking skill.

Table 3.1 Thinking Verbs

Throughout this book, we give tips that will help you develop your thinking skills. You have read about the learning cycle and the importance of applying your knowledge. You will learn tips for remembering information from your notes and classes. Preparing for class requires you to analyze what you know and what you need to learn. The sections on listening and reading will help you develop your understanding skills. Look for those tips and practice them.

In this chapter, we will focus on critical thinking (evaluating) and creative thinking. They deserve specific focus because they are likely to be the skills you have least practice with. These are the skills most helpful for success in college and in “real life.” Creative thinking will help you come up with possible solutions for problems and new ideas. Critical thinking will help you decide which of those ideas have most merit and deserve to be implemented.

Key Takeaways

• We use different types of thinking skills to address different requirements, and these skills are classified in Bloom’s taxonomy.
• You have been using many thinking skills since childhood.
• Two very important thinking skills you will need to develop for success in college and in life are critical (or evaluative) thinking and creative thinking.

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.

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

Table of contents

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.

Prevent plagiarism. Run a free check.

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 and Decision-Making: What is Critical Thinking?

Lesson 1: what is critical thinking, what is critical thinking.

Critical thinking is a term that gets thrown around a lot. You've probably heard it used often throughout the years whether it was in school, at work, or in everyday conversation. But when you stop to think about it, what exactly is critical thinking and how do you do it ?

Watch the video below to learn more about critical thinking.

Simply put, critical thinking is the act of deliberately analyzing information so that you can make better judgements and decisions . It involves using things like logic, reasoning, and creativity, to draw conclusions and generally understand things better.

This may sound like a pretty broad definition, and that's because critical thinking is a broad skill that can be applied to so many different situations. You can use it to prepare for a job interview, manage your time better, make decisions about purchasing things, and so much more.

The process

As humans, we are constantly thinking . It's something we can't turn off. But not all of it is critical thinking. No one thinks critically 100% of the time... that would be pretty exhausting! Instead, it's an intentional process , something that we consciously use when we're presented with difficult problems or important decisions.

Improving your critical thinking

In order to become a better critical thinker, it's important to ask questions when you're presented with a problem or decision, before jumping to any conclusions. You can start with simple ones like What do I currently know? and How do I know this? These can help to give you a better idea of what you're working with and, in some cases, simplify more complex issues.  

Real-world applications

Let's take a look at how we can use critical thinking to evaluate online information . Say a friend of yours posts a news article on social media and you're drawn to its headline. If you were to use your everyday automatic thinking, you might accept it as fact and move on. But if you were thinking critically, you would first analyze the available information and ask some questions :

• What's the source of this article?
• Is the headline potentially misleading?
• What are my friend's general beliefs?
• Do their beliefs inform why they might have shared this?

After analyzing all of this information, you can draw a conclusion about whether or not you think the article is trustworthy.

Critical thinking has a wide range of real-world applications . It can help you to make better decisions, become more hireable, and generally better understand the world around you.

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.

Figure 3.2 Types of Thinking Skills

All of these thinking skills are important for college work (and life in the “real world,” too). You’ve likely had a great deal of experience with the lower-level thinking skills (yellow section). The midlevel skills are skills you will get a lot of practice with in college, and you may be well on your way to mastering them already. The higher-level thinking skills (red section) are the most demanding, and you will need to invest focused effort to develop them.

Exercise: Thought Inventory

Think about Figure 3.2 “Types of Thinking Skills”. Are you using all six thinking skills? Reflect on your schoolwork in the past three weeks and identify specific examples where you used each of the thinking skills. Use the comment column to write notes about the skills that are second nature to you and those you would like to develop further.

Look at the lists of things you actually did in each case. Notice that there are certain verbs that apply to each skill set. When you see those verbs as a prompt in an assignment or an exam, you will know what kind of thinking the instructor expects from you. Table 3.1 “Thinking Verbs” lists some of the most common verbs associated with each thinking skill.

Table 3.1 Thinking Verbs

Throughout this book, we give tips that will help you develop your thinking skills. You have read about the learning cycle and the importance of applying your knowledge. You will learn tips for remembering information from your notes and classes. Preparing for class requires you to analyze what you know and what you need to learn. The sections on listening and reading will help you develop your understanding skills. Look for those tips and practice them.

In this chapter, we will focus on critical thinking (evaluating) and creative thinking. They deserve specific focus because they are likely to be the skills you have least practice with. These are the skills most helpful for success in college and in “real life.” Creative thinking will help you come up with possible solutions for problems and new ideas. Critical thinking will help you decide which of those ideas have most merit and deserve to be implemented.

Three Types of Thinking and Why They’re All Important

By Krista Gerhard

How often do you think about thinking ?  For most of us, the answer would probably be, “not very.”  As we manage our lives and do our jobs, we tend to employ different approaches to thinking without really being aware of it.  For the most part, that works. 

However, the times keep on changing and it’s becoming increasingly important for us to be more conscious of how we think, and to develop our thinking skills.  This is especially important if you work in a Learning & Development (L&D) role because you’re also responsible for developing those skills in others and helping them succeed in this changing world. 

In this article, we will define three very important types of thinking:  Critical, Strategic, and Entrepreneurial.  In subsequent articles, we will go into more detail about how L&D can use—and teach—all three forms of thinking.

Multiple types of thinking skills are becoming more important

In its Future of Jobs Report, the World Economic Forum shares its 2022 Skills Outlook .  This is a listing of the top skills that employers will demand in the global economy of 2022.  Let’s take a look at the top 10 growing skills:

• Analytical thinking and innovation
• Active learning and learning strategies
• Creativity, originality and initiative
• Technology design and programming
• Critical thinking and analysis
• Complex problem-solving
• Leadership and social influence
• Emotional intelligence
• Reasoning, problem-solving and ideation
• Systems analysis and evaluation

It’s interesting that at least 7 of the top 10 hinge on one or more forms of thinking mentioned above.  For many roles, individuals will need to be proficient critical, strategic, and entrepreneurial thinkers.

Critical, strategic, and entrepreneurial thinking:  What’s the difference?

Critical thinking.

We’ve written before about critical thinking , including the link between critical thinking and confidence.  However, we didn’t offer a definition.  Well, here it goes: 

Critical thinking is an effortful and continuous analysis and revision of one’s thinking processes and output for reasoning and logic and to eliminate bias in order to increase the probability of a desirable outcome. 1

Wow!  That’s a mouthful.  It basically means that critical thinkers actively think about how they think! They gather, synthesize, and evaluate information in order to make decisions; however, they do so in a way that uses logic and reason.  Plus, they consciously work to avoid falling prey to various cognitive biases that can cloud their judgement.  At its heart, critical thinking is analytical and logical.

Strategic Thinking

Strategic thinking is a mental process that is applied when one is trying to achieve some goal or set of goals.  Whereas critical thinking is all about analysis, logic and reason, strategic thinking is about planning.  It involves being able to understand cause and effect and seeing several steps ahead in order to achieve some desired outcome. 

Strategic thinking does not exist in a vacuum.  Strategic thinkers typically must employ solid critical thinking skills to analyze and understand their current situations, then layer in strategic thinking to forge a path forward.  When thinking strategically, a person should also use critical thinking to discern the likely outcomes of one planned action versus another.

Entrepreneurial Thinking

Entrepreneurial thinking can also be called creative thinking.  It involves seeing things differently than most other people.  Entrepreneurial thinkers are able to identify opportunities that others may miss.  They’re also able to see problems and develop solutions that others might consider “outside the box.” 

Entrepreneurial thinking also doesn’t exist in a vacuum.  An entrepreneurial thinker must think critically about the ideas that he or she generates.  Otherwise, they run the risk of developing “flashy” ideas that are unworkable in the real world.  They must also think strategically when working to bring the best entrepreneurial ideas to reality.

Here’s another important point:  critical, strategic, and entrepreneurial thinking skills can be taught.  Sure, most people will have differing natural aptitudes for various types of thinking. For example, Person A might naturally be more “entrepreneurial” in their thinking whereas Person B might be more inclined to think critically.  However, people can learn to use all three types of thinking.

Coming next…

In upcoming articles, we’ll explore two different aspects of all this that will be relevant to L&D professionals.  First, we’ll take a look at how L&D can use critical, strategic, and entrepreneurial thinking to improve the way L&D engages with its stakeholders and increase its effectiveness.  Second, we’ll dive into how L&D can help improve its learners’ critical, strategic, and entrepreneurial thinking skills.

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. Political and business leaders endorse its importance.

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. Morevoer, 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 line 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. She forms a plan to consult her regular physician on her return about the blood pressure medication.

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), others on the resulting judgment (Facione 1990a), and still others on the subsequent emotive response (Siegel 1988).

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 frequency 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 frequency 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 2016) 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.

Critical thinking dispositions can usefully be divided 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) (Facione 1990a: 25). 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.
• 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), and Black (2012).

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.

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? Abrami et al. (2015) found that in the experimental and quasi-experimental studies that they analyzed 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), and Bailin et al. (1999b).

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.
