This is such a lazy answer to a complex problem-set. The reason why it always breaks down too this, is that we can not perceive "different". All we have is "similar" to us comparison. Not similar to us is judged by outcome - which is why stupid/godlike flickers. Genius is repeatedly not getting it, judging it stupid, but the outcome is working/superior.

The sad truth is, we cant really see other people behaviour-wise. Aliens could be walking in our midst and we couldn't perceive them.
