Admixture study in US blacks: the more African, the lower the score. we do this on many traits of medical interest - works fine.

That's bunk. Way too many non-genetic factors involved. Just as African-American men have a high rate of kidney disease, but the effect is not genetic, it's entirely due to lower socioeconomic status.

So controlling for SES there's no difference in rates of kidney disease? I hadn't heard that. Is the same true of hypertension?

I read that in an old paper but it appears to be wrong, since the APOL-1 gene is a risk factor with higher freq from African ancestry.

Are you starting to notice a pattern of Greg turning out to be right? Does that reduce your confidence in other areas where he claims something you think is wrong?

I think the evidence for the existence of different cognitive adaptations is weak, and that culture and environment are sufficient explanations for the data.

Is there evidence that culture is MORE important than adaptations? A reasonable person might be agnostic between explanations in the absence of evidence, rather than assuming it must be entirely one or the other.

So Occam's Razor points to culture alone. But I grant that brain adaptation *could* have happened. I just don't see clear evidence of brain differences between populations.

> I just don't see clear evidence of brain differences between populations. So differences in brain volume and neuron count just don't count? Or are those caused by "culture"?

"Ha! You can disprove my case by using a primitive measuring device!" This is supposed to be an argument? Calipers *measure* the same underlying phenomenon as a whole host of other measures - MRIs, weighing brains from cadavers, measuring skull volume through other means, etc.
