AssassinateB : "Did he not attempt to say why men do that and women don't?"
"That" being "work crazy hours with crazy stress to scrabble to the top of the heap. And yes, he does give his explanation in his lectures and I also gave an explanation earlier in the thread.
In substance it's related to his lobster story. There's a male dominance hierarchy in all social animals. In lobsters (and most animals) it's essentially about size, power and fighting strength. In humans there's a bit of that pure power thing, but since we're complicated cretaures with big brains, the male human dominance hierarchy is multifaceted. You can scrabble to the top of the heap as a political dictator, by force. Or you can be Bill Gates, or a top corporate manager. Or banker. Or lawyer. Or you can be Picasso. Or Mick Jagger. Or Woody Allen. Or Michael Jordan. Or Niels Bohr. Or Pasteur. Or Tolstoy. Or Sartre. And so on. There are lots of human heaps you can scrabble to the top of - if you are very intelligent, very conscientious, possibly creative, very hard working, very single minded, and very willing to sacrifice the rest of your life to scrabbling to the top. Or as near the top as you can manage.
If you get near the top you win status. Like the lobster who wins his fights. And with status comes extra nookie. In animals where it's just a fight, you get extra nookie because you chase off the little guys, and the gals have no choice but to mate with you. In humans, where the gals get a choice of who they're going to mate with gals - on average - go for men who are equal to them in status, or higher. Hence the higher up the status pole you are, the more gals will be interested in you. So if you're a man, the reward for sacrificing your life to scrabble up the pole is extra gals who are interested in you, extra nookie, and so extra descendants.
So why do a small percentage of men spend their lives scrabbling to the top ? Evolution. In the past, human males who scrabbled to the top left more children than men who didn't scrabble to the top. There is no corresponding dynamic for females, because the number of children a woman has is not affected by how many mates she has. Her chances of leaving more descendants are increased not by more mates, but by having a mate with high status - one who can provide her with resources and protect her. Hence evolution wasn't telling her female ancestors to hunt for more mates, it was telling her ancestors to hunt for a mate with status. Or if she's going to have a bit on the side, and mate with a man who isn't going to provide any resources or protection, it's better to mate with a high status male than a low status one. Because your male descendants will then acquire better genes and so will get higher status and pass your genes on through their mating success.
Evolution, of course, does not have to plant its instructions in our conscious minds. Very able men can scrabble to the top just thinking " I wanna be on top" without explicitly calculating the nookie reward. And women have always fancied the top dog without consciously calculating that there's a pay off in terms of protection for them and their children.
btw this is not an idiosyncratic Peterson flight of fancy. It's evolutionary biology 101.
- I throw in Woody Allen and Sartre as illustrations of the fact that if you have high status, you can pull a lot of really good looking birds without being an oil painting. I could have mentioned Henry Kissinger but I didn't want to cause any seizures. .
