Nice article, but the guy is overthinking the whole thing.
Winston mentioned that in the U.S., smart people are stigmatized as undesirable nerds. (Note that this is not the same as someone with a fancy degree or high status.) This is not the case in many other countries, especially in East Asia! Chinese women will often be turned on by smart guys.
So,
(1) People are supposed to choose mates who will produce and raise the best offspring.
(2) Many Western women avoid smart men as potential mates.
Now what does that say about what future-generation Americans are going to be like?
