Professor Suzanne Rab Takes a Critical Look at Critical Thinking

By Professor Suzanne Rab

Critical thinking is a vital skill at university, and in life.  Despite its frequent endorsement in education, there is no clear consensus about what it means in practice.  Rather like the elusive search for a definition of obscenity[1], “we know it when we see it”. But it can be hard to define what critical thinking is and even harder to nurture this  skill.  I will focus on some reflections from the 2021 Level One Law Conference where I presented this topic to students transitioning to level two law studies.

The term ‘critical’ comes from the Greek word ‘kritikos’ meaning discerning.  So, critical thinking is a deeper kind of thinking in which we do not take things for granted but where we question, analyse and evaluate what we read, hear, say or write.  It is a general term used to identify mindsets, skills and behaviours that contribute to effective decision-making.

Before looking at a definition of critical thinking, it is helpful to emphasise what it is not.  It is not an automatic response; it is not attained overnight (it requires practice and hard work) and it is not simply being (highly) critical of everyone else’s thinking but your own.

However, it is useful to try to define it (if only to illustrate the limitations of definitions which are not ends in themselves).  I find helpful the working definition that: “Critical thinking is, in short, self-directed, self-disciplined, self-monitored, and self-corrective thinking.  It presupposes assent to rigorous standards of excellence and mindful command of their use. It entails effective communication and problem solving abilities and a commitment to overcome our native egocentrism and sociocentrism.” (Paul and Elder, 2008).

I try to encourage students not to trust your first response by using an easy puzzle that invites an answer that is intuitive, appealing and wrong:

A bat and a ball cost £1.10

The bat costs £1 more than the ball

How much does the ball cost?

The intuitive answer that immediately springs to mind is “10p”   About 80% of university students give the answer “10p”.  BUT it is wrong!

If the ball were to cost 10p, the bat would cost £1.10 (i.e. £1 more), and then the total cost would be £1.20, rather than the required £1.10.  The correct response is “5p” (i.e. the bat costs £1.05).  The explanation for the widespread “10p” bias is that people substitute the critical relational “more than” statement by a simpler absolute statement.  That is, “the bat costs £1 more than the ball” is read as “the bat costs £1”.  Hence, rather than working out the sum, people naturally separate £1.10, into £1 and 10p, which is easier to do.  People are over-confident and it takes time and effort to think and check.

The puzzle is taken from Kahneman in Thinking, Fast and Slow adapted for a UK audience where the bat and ball problem is used as an introduction to the major theme of the book: the distinction between fluent, spontaneous, fast ‘System 1’ mental processes, and effortful, reflective and slow ‘System 2’ ones.  The explicit lesson is that we are too willing to lean on System 1, and this gets us into trouble.

Critical thinking done well meets high standards of reasoning.  Universal intellectual standards are standards which when applied to thinking provides a means of checking the quality of reasoning about a problem, issue, situation, or question.  Thinking critically entails knowledge and application of the standards: clarity, accuracy, precision, relevance, depth, breadth, logic, significance, and fairness.

If students are ambivalent about critical thinking, it can be helpful to anchor its value in the world beyond academic study.  Critical reasoning tests, also known as critical thinking tests (CTTs), are psychometric tests commonly used in graduate, professional and managerial recruitment.  These high-level analytical tests are most commonly encountered in the legal sector, but other organisations such as the Bank of England also use them as part of their selection process.  I have found it useful to explain the relevance of critical thinking beyond university studies, in terms of employment opportunities in law and elsewhere and in life more generally where critical thinking is indispensable to thrive.

  1. What happens to outcomes if the high standards of reasoning are met? It looks like the standard’s measures are all subjective, for example “fairness”. Are there examples of the ‘so what’?
