Home Jobs & Education What is Critical Thinking and How to Improve It?

What is critical thinking if not thinking smart? Simply put, the concept refers to the ability to think clearly. It involves systematic analysis or what it’s more pretentiously called critique. As the intellectual capacity of making precise judgments, it also implies evaluating and reasoning.

Critical thinking is exemplary of how the left hemisphere of the brain works. Its counterpart, creative thinking, is typical, of course, of how the right hemisphere of the brain functions.


What Is Critical Thinking as Defined by Theorists?

For a more informed answer to the question, let’s see how experts define the concept of critical thinking, and here we refer first to the representatives of the National Council for Excellence in Critical Thinking, Michael Scriven and Richard Paul.

Critical thinking is the intellectually disciplined process of actively and skillfully conceptualizing, applying, analyzing, synthesizing, and/or evaluating information gathered from, or generated by, observation, experience, reflection, reasoning, or communication, as a guide to belief and action.
