What is Critical thinking? 

There are many definitions of Critical thinking. Some of them very long and comprehensive in coverage of everything critical thinking includes, while others are short definitions but  very succintly summarize what Critical thinking is and what leads to becoming a critical thinker. Here are three of them.

1. "Critical thinking is the process of making clear reasoned judgments" ...Beyer, 1995

2. “Critical thinking is the ability to look at a situation and clearly understand it from multiple perspectives while separating facts from opinions, myths, prejudices, hunches (intuition) and assumptions”….. Pearsons

3. "It involves the ability to questions assumptions etc. in order to make logical decisions based on consideration of the options and evaluation of all facts". … Pearsons

What do you need to learn to become a critical thinker? 

All of us know critical thinking by its absence or critical thinking traits that we see in a person. When someone makes a foolish decision or applies the first solution that comes to their mind in problem-solving, we know that critical thinking has not been exercised. But critical thinking itself has not been defined for most of us -either in our education or later in the workplace.

Maybe we see Critical thinking as applied common sense. Critical thinking may also be defined as the process of making clear reasoned judgments about any claim, issue, or solution to a problem. Some also define it as the process of determining whether a claim is true or false. There are more complex definitions such as Critical thinking is skilled and active participation and evaluation of observations and communications, information, and argumentation (Fisher and Scriven). 

None of the academic definitions manage to communicate what Critical thinking is, its elements, and how it could be useful in the workplace, education, or life. To better understand what Critical thinking is, it is useful to look at the actual elements that go into Critical thinking, and see how they apply in various situations at work and in life.

Critical thinking is the process of making clear reasoned judgements. 

Elements of critical thinking

There are three elements that aid in critical thinking, and another three that obstruct critical thinking.

Logical reasoning: You would not expect an accountant to draw up a balance sheet without the knowledge of the debit/credit system. However, we are expected to be absolutely logical in our reasoning about problems and decision making. The absence of a formal introduction to logical reasoning results in even the most intelligent people miss a few steps in their reasoning. There are three main types of reasoning: Deductive reasoning, Inductive reasoning, and Causal reasoning. Of these, Inductive reasoning and Causal reasoning as the most commonly applied systems of logic in the workplace, education, and our daily life.

Clear thinking and communication: Discussions often end up at cross-purposes and pointless due to a lack of clear communication, and this lack of clarity is often due to a lack of definition of terms, ambiguity, and deliberated or unintended use of vague language.

Credibility: We are often required to evaluate suppliers and people to decide whether to work with them or not. We also rely on the opinions of others to make a varying range of decisions for the business, in education and life. How do we know how much credibility we should attach to the advice we get from these people, or how do we determine whether a supplier will be dependable or not? There are some simple principles that we can use to help us in our process of making judgments about credibility.

Elements that obstruct 

 Rhetoric: In the context of Critical thinking, rhetoric is the use of language to evoke emotions in us and persuade us into belief or action. Words have the power to express, elicit images, and evoke emotions in us. They have tremendous persuasive power or what can be called rhetoric force or emotive force. When a leader calls on soldiers to sacrifice lives for the sake of their country, or when citizens are passionately asked to join a protest to protect freedom, these are appeals to our emotions and not our logical reasoning. Rhetorical language and devices can cloud our ability to reason logically. 

Cognitive biases: A cognitive bias is a systematic error in our thinking and judgment and can be due to a number of different reasons such as faulty memory or perception and processing errors of our brains. There could be a number of other reasons, and scientists are still researching the causes of these cognitive biases. A cognitive bias is different from Fallacies in the sense that these errors are based on our incorrect perception and processing of information by our brains, whereas fallacies are simple errors in reasoning. Knowledge of fallacies can help us avoid reasoning errors, but cognitive biases may arise even if we have knowledge of these biases. Often the only way to mitigate errors due to cognitive biases is to rely on data or seek third party opinions.
