You guys are wayyyyyy over thinking this critical thinking bit.
Critical thinking is being critical of your thinking.
Not just willy-nilly choosing something, but actually being critical of each and every aspect of the decision making process.
All critical thinking is not created equal as the critic could be a imbecile.
"You were not there for the beginning. You will not be there for the end. Your knowledge of what is going on can only be superficial and relative" William S. Burroughs
