>>511197503 (OP)Hypergamy assumes men and women sleeping promiscuously, as a woman body count gets higher the chance of that woman divorcing gets significantly higher and it scales well.
Intuitively men don't like women with high body counts because the only way of assuring paternity is that woman sleeping with you only.
From the first statement our ancestors would of used their anecdotal evidence and pattern recognition to understand this problem and associated disloyal women with the behavior of being a slut.
Because we have this innate intuition about this particular case, this is our primal instinct in action (disgust with women w/ high body count) trying to assure paternity because paternity tests once upon a time didn't exist.
Your promiscuous sexual history creates a reference for fun in which you'll be competing to achieve again which at the individual level is an incentive not to be dedicated to one person, you can think about this in Freudian terms such as the ego, ID, super ego.
In this respect "ignorance is bliss" is true, because you don't know what your missing out on and that's a good thing.
If you want a society where Stacy isn't fucking you over for Chad and ruining your marriage, disincentivizing promiscuity can mitigate this risk.
