Reflected thoughts. The groups we are talking about is put together by individuals anyway, and in any of the groups mentioned the smartest one will be a lot smarter than the dumbest of the other group. The smartest person in the "dumbest" group can easily be smarter than the smartest individual in the smartest group as well, so... The idea of this having any practical importance is in at its best absurd, at its worst extremely dangerous. Good post.
