That's an article apparently from a white nationalist, Jordan Lasker, a collaborator of Emil Kirkegaard's.

Do you have any comments about the article itself?

Thanks! I read the introduction, and will add it to my weekend reading list.

The author objects to treating 'g' as a causal variable, because it doesn't help us understand how the mind works. He doesn't deny that 'g' is useful as a predictive variable.
