Evolution doesn't favor high IQ. Women select based upon the hunter/warrior criteria. Don't you remember high school?
If evolution didn't favor intelligence, why did brain size triple in the last 2 million years?

It’s like owning a boat. Much downside maintaining a high IQ brain. It’s best to have access to someone with a high IQ when needed. Culturally I’m descended from viking raiders... so I implied this earlier,https://twitter.com/russ_erickson/status/1079074062159265792?s=21 …

It has, of course. I was just in the mood to point out that it doesn't seem to be the top criterion for men or women. It's the football team that gets the girls, not the math club. And guys don't have posters of women with big brains on their walls.

It favored something that 'IQ' is just an indicator of. Note: 'Intelligence' as favored by evolution ≠ IQ. I think IQ captures just part of it and is an indicator of something else.
