Critical thinking is that mode of thinking - about any subject, content, or problem - in which the thinker improves the quality of his or her thinking by skillfully taking charge of the structures inherent in thinking and imposing intellectual standards upon them.
This includes analyzing and evaluating information that is provided, whether that information is through observation, experience or communication. The core of critical thinking is being responsive to information and not just accepting it. Questioning is the most important part of critical thinking. It is a part of scientific, mathematical, historical, economic and philosophical thinking, all of which are necessary for the future development of our society.
