"In the mosaic of America, three groups that have been unusually successful are Asian-Americans, Jews and West Indian blacks — and in that there may be some lessons for the rest of us."

"Do African immigrants make the smartest Americans? The question may sound outlandish, but if you were judging by statistics alone, you could find plenty of evidence to back it up. In a side-by-side comparison of 2000 census data by sociologist John R. Logan at the Mumford Center, State University of New York at Albany, black immigrants from Africa average the highest educational attainment of any population group in the country, including whites and Asians."

I think it is more cultural than genetics.

"black immigrants from Africa average the highest educational attainment of any population group"

-- this is because of selection bias: only the brightest Africans get the chance to immigrate to the US.

So, isn't it also so with Asians?

I don't mean to make any particular assertions about one ethnicity or another. My point is simply that, given the (genetically driven) physical variance between ethnicities, I expect there is a reasonable chance of (genetically driven) mental variance as well. In what way? I have no idea, and no opinion.

Culture is often inherited along with genes.
