Followup to:  An Alien God, Adaptation-Executers not Fitness-Maximizers, Evolutionary Psychology

Before the 20th century, not a single human being had an explicit concept of "inclusive genetic fitness", the sole and absolute obsession of the blind idiot god.  We have no instinctive revulsion of condoms or oral sex.  Our brains, those supreme reproductive organs, don't perform a check for reproductive efficacy before granting us sexual pleasure.

Why not?  Why aren't we consciously obsessed with inclusive genetic fitness?  Why did the Evolution-of-Humans Fairy create brains that would invent condoms?  "It would have been so easy," thinks the human, who can design new complex systems in an afternoon.
