Actually, I want to add something to this. The general vibe in this research area is NOT that you cannot compare IQ with genes. Indeed, its more or less an accepted fact that some portion of IQ and measures like it are indeed heritable. The specific issue this person faced is in the use of race. I'm not suggesting that we accept all the woke orthodoxy whole cloth, but race really is a socially constructed concept. No person out there in the world is "of a given race" as a scientific fact. People have genes, they don't have races. The scientific community recognizes that genes influence intelligence, but has no interest in promulgating the frankly dumb idea that humans have distinct races, probably because the last time people got really into that idea it lead to concentration camps, apartheid, and the pointless destruction of vast swaths of human potential.

The main issue with the research described is that it uses genes to construct a racial narrative. If that is the world you want to live in, you do you, I guess, but I would prefer that people not be pigeon holed on the basis of (for example) arbitrary qualities like "European Ancestry," which the person explicitly states they constructed a sort of genetic fingerprint for. In a meritocratic society people should be judged on their performance, not some inference people make about what genes they have on the basis of their level of melanin, to refer to the study this guy is talking about.
