Critical thinking as defined by this website is, “the ability to think clearly and rationally.” It also includes the ability to engage in reflective and independent thinking: The understanding of logical connections between ideas, identifying and evaluating arguments, or solving problems systematically.
What is critical thinking, not? It’s not a matter of accumulating information. It is not being overly critical of people, or argumentative for the sake of being hostile, or disagreeable.
People seem to often get the two confused and it leads to headaches, ill feelings, and sometimes even violence depending on the situation. I think the most telling thing is that to have a good critical statement, both parties must be one who are able to critically think themselves. This way, the processes involved are on the same page and thus, can lead to a better conclusion or theory.
