Simply, I feel like he's coming at the issue from the perspective that men-women relationships are transactional. I think that's wrong, and that it is an incel view of the problem. With no disrespect to incels, because I also grew up thinking like that.
Also I'd say the definition the article uses for "intelligence" is reductive. There's more to intelligence than pure logic.
Romantic relationships aren't that different from friendships. And you wouldn't try to be friends with someone just because they have a nice car or score well at IQ tests. It's all about being a good/fun person. And that can be pretty subjective, compatibility plays a big part. People with similar interests and values are more likely to get together.
