It’s hard to have a good faith discussion about human intelligence with anyone, especially about the genetics of intelligence. This 2019 blog post by Ewan Birney and others is the best I’ve come across on the subject so far.

For most traits, including IQ, it is not only unclear that genetic variation explains differences between populations, it is also unlikely […] The genetic variants that are most strongly associated with IQ in Europeans are no more population-specific than any other trait. To put it bluntly, the same genetic variants associated with purportedly higher IQ in Europeans are also present in Africans, and have not emerged, or been obviously selected for, in recent evolutionary history outside Africa.

Here are some more questions about intelligence.
