I recall that article advising men not to investigate their ancestry because it's possible they'd find out about how common infidelity is. And just thinking how also most woman don't find most men attractive and that top 10% stuff. And I know that's just for shallow dating judgement. But it's still enabled an explosion of casual sex. Or how even in this day and age, if you can be tricked into signing the birth certificate with false believev you are the father, then you can still be liable for payments. I can't help but feel in a sexually liberated society, there would be a non-organised collective agenda against men for the sake of what is mutually beneficial for woman. And for men, who don't have free easy access to sex as woman have, to not know this information. And increase that safety net of having a provider if you did decide to cheat.
