Actually, black Africans have similar average IQs to African/Americans. (Actually, slightly lower, as would be expected from a low-income country.) Those few who come here are fairly obviously the cream of the African crop.
What about black Brits...at least they can speak properly.
Isn't there a culture in the world where there is a black demographic that thrives in an education-rich environment, and whose "average IQ" can be more fairly assessed?
You see plenty of blacks on the floor of the NY Stock Exchange, they can't be dummies doing that, and they probably shouldn't have their "average IQ" unfairly downgraded by the gang-banger/ghetto-rat "mentality".
