More Things I’m Unaware Of

In regards to the previous post, it’s cases like the Buraku that are precisely what I’m unaware of.  It certainly sounds like really good evidence–and unsurprising evidence.  In evaluating cross-ethnic group differences in IQ, controlling for the vast early life influences on cognitive development is going to be nearly impossible.  My understanding is that twin studies do that for heritability of IQ, but I’m unaware of cross-cultural studies that show the same thing (not that what I know tells you anything.  See the disclaimer).
