Hmmm, I think there are some things in modern dense societies which influence selection.
-- defensive driving
-- fertility which is influenced by chemicals (either self administered or pollutants)
-- violent crime
Not all of those things require intelligence, but I think most intelligent people make better lifestyle choices.
