When I studied at a university, I was told that I should question everything rather than simply accept things. A good example of critical thinking to me at least is the kind of thinking that led to an explanation of quantized spin (initially called "space quantization"), the first good evidence of which was the Stern-Gerlach experiment the results of which were unexpected. Another experiment was the Einstein-deHass one which was wrong by a factor of two. Critical thinking about the results of experiments, particularly unexpected results, led to revisions of theories and eventually to a more complete quantum theory. Of course, the scientists could have just accepted the results and not thought about them (yeah, right). And, btw this: "There are a minority of pedagogical scholars out there that have temperamentally raised the question of what the hell critical thinking actually is and why we are so convinced that it will solve all our problems?" is a crock. Critical thinking is not something anyone I know is convinced will "solve all our problems". I note there is a grammatical error in the quoted sentence, can you apply some critical thinking and see what it is?
