No Your Self.

      Know what you know, then figure the rest out. If you answer the questions you know for sure, then you can use logic or intuition for the rest. Logic is simply taking something you don't know and using facts about it you do know to deduce the answer. Associations of things..... 7 degrees of Bacon! Intuition is that inner logic that associates things on a subkevel, and it generally gets it right. You don't have to know, you just have to reason.
