Critical thinking is a type of clear, reasoned thinking. According to Beyer (1995) Critical thinking means making clear, reasoned judgements. While in the process of critical thinking, ideas should be reasoned and well thought out/judged.

The National Council for Excellence in Critical Thinking defines critical thinking as the intellectually disciplined process of actively and skillfully conceptualizing, applying, analyzing, synthesizing, and/or evaluating information gathered from, or generated by, observation, experience, reflection, reasoning, or communication, as a guide to belief and action.
