There are tests, there are classifications, there are skills.  This conversation.... puts all of that into a blender.  <br> I'm of a group of people that surmise testing beyond a certain childhood age distorts the concept of a generalized "i.q. test".  There are too many facets of being a human that can subjectively be given as arbiters of being "smart" that ignores another facet.  Those facets start changing with education and experiences, as you age the initial state becomes hidden.
