-Those who are too unfulfilled with mere survival and silly games want time for artistic hobbies. In a harsh world of endless long work hours they don't prosper. A different sort prospers...
-But being unfulfilled in the first place can manifest itself in more ways than creativity. For most it means wanting to sleep around. Which is a very good quality for successfully spreading your genes far and wide.
-There is an edge in general where intelligence starts going against "prospering." Where a person understands very well Camus' The Myth of Sisphus, the absurdity, the futility of life and starts having less interest in mere survival. And thus doesn't prosper as well.
-Perhaps they can... or at least could go even further. Into rejecting the illogic of emotions and sex and thus "prospering" even less. Of course anything outside the norm doesn't do well as long as the situation is normal.
-Anger was a beneficial mutation in the far past solely because it increased the chance that violence would be successful. Not as useful today although better than indifference still...

-Evolved jealousy in women which can manifest in many ways but ultimately was to stop men from sleeping around.
-evolved mindless conformity

-those who fall in love hard prosper, right up to the edge of killing themselves when the other doesn't feel the same
