That’s kind of the attitude I was alluding to.
We have no problem acknowledging that racial differences can lead to physical differences - sickle-cell traits, eyelid shapes, skin color, higher or lower rates of lupus or Type-2 diabetes, stomach cancer, etc.
But somehow we pretend as if the brain cannot be influenced by genetics likewise. The odd thing is, we even acknowledge that the brain can differ on gender/sex, can differ even in political differences (it’s known that conservatives have greater “fear” attributes in brain wiring than liberals,) can change in age, can change or be different based off of a dozen different factors, etc. But somehow the idea that genetics/race could possibly have any differences in brain matter, neuron wiring, etc. is considered taboo. The brain is immune to racial/genetic factors, but is vulnerable to everything else, so goes the logic.
