I mean, if you’re articulate, conniving, but not creative, and unburdened with moral intuition, then it’s deterministic that you will specialize in parasitism by false promise or moral hazard – and it’s rather obvious that you would develop a group evolutionary strategy that takes advantage of your ability to create exception. Take your average woman’s intuition and means of competition by gossip and undue compliment, remove all fear, and that’s what you get. Reversal of dimorphism seems to have been an effective strategy.
