Dude, thanks for the link. It appears the big words confused you. From the first link:
"(a) putative genetic racial differences do not account for a major portion of the IQ performance difference between racial groups, and (b) black and interracial children reared in the culture of the tests and the schools perform as well as other adopted children in similar families.""
So, an IQ difference of 18 points between Blacks & Whites in the Transracial adoption study isn't genetic?
That's funny, because that's the same 18 point difference between Whites & Blacks in general USA population.
Of course they have to say that, if they didn't they'd go the way of James Watson.
Of course, you can't think for yourself, I've dealt with enough Western Europeans to realize you're a hopeless, desperate & dumb peoples.
