You need to improve your communication skills, Corny.  This?  That?  WTF are you trying to say?  Critical thinking is a skill that is indeed learned.  Schools today don't teach it.  The chart I posted is but a tool to help learn that skill, and it's by no means complete.  Each topic requires a set of relevant techniques for evaluating (thinking about) it.  One size does not fit all and the kind of vague generalizations you're making do not help further understanding.
