Early twin studies of adult individuals have found a heritability of IQ between 57% and 73%, with some recent studies showing heritability for IQ as high as 80% - https://en.wikipedia.org/wiki/Heritability_of_IQ

> Are you staring aghast at the latest cluster of immigrants in this country, are you fretting that they're breeding like rabbits? That generation of children will be the people your kids grow up with, go to school with, date, and marry. It may take a while, but eventually, your line will merge with theirs.

Please don't spread the great replacement conspiracy theory.

> There are no grounds to argue that there are distinct subpopulations of people with different potentials for intelligence. Genes flow fluidly

I don't see why we need to talk about "distinct subpopulations" at all, when individuals suffice. Besides, if you think "gene flow" means intelligence is immune to evolution, doesn't that apply to every other trait as well? What you're arguing is that evolution doesn't happen.

He's literally describing what the believers of that dumb "theory" believe; he isn't "spreading it".

Do you also accuse the Wikipedia page documenting Eugenics of supporting it?

what? did you even read the article?

as for the twin experiment, he's not talking about heredity of iq, he's talking about heredity of perceived/expressed iq. there's an important difference that gets lost in the noise.

I did. It's using a lot of words to obfuscate its central thesis: That even if you select against a trait, that trait won't diminish. It may as well be arguing that antibiotic resistance cannot develop, or that corn can't be selectively bred to increase yield.

It's sad that even 163 years after On the Origin of Species, people are still trying to deny it.
