Critical thinking is a more in-depth way of thinking about questions. Rather than assuming an answer is correct, critical thinking forces you to look at other possible explanations. Some people refer to critical thinking as "thinking about thinking". This means that when you think critically you need to analyze and evaluation information that is obtained from a variety of sources, including observation, experimentation, evidence, reasoning, and communication. Critical thinking is not just about coming up with conclusions. It is about putting these conclusions to test in order to prove that they are correct or incorrect.
