Critical thinking is reasonable reflective thinking focused on deciding what to believe or do. Critical thinkers are intellectually curious, seek answers to various questions and problems, are open-minded and accept a variety of positions if valid, know how to handle confusion by avoiding quick decisions, avoid irrelevant information, are able to control their emotions, are sensitive to others, and know when to admit they don't know something. Critical thinking is a learned skill essential for making decisions and can be improved through education.
