From your article, which claims that intelligence is reflected in how "foldy" your ears are:

>Imagine that you know that you aren’t so smart. It’s difficult to do well in class. Then you hear of this theory, go check your ears in the mirror, and find that your ears are not so foldy. Maybe they’d feel relief at understanding why things are the way they are. They could then endeavor to do better for their kids and the next generation armed with the knowledge of prenatal nutrition and its benefits

What kind of crackpottery is this?

>My personal opinion is that only people with these biologies are not Aristotle’s natural slaves, only able to live in the worlds of others.

This is the kind of fatalist intelligence eugenics that makes me recoil.
