Dr.K, thank you for an intelligent reply.
I have not seen data on the difference not existing in blacks in England.
I have seen data on the difference being decreased here in the United States.
When you take blacks out of the ghetto, give them a stable home life, and high incomes, they perform better, but still well below their white suburban neighnors.
The gap becomes the smallest among blacks who are adopted and raised in white families.
I forget the numbers.
I think the reasons are an all of the above answer.
The social and cultural reasons are undeniable, but they don't make up all the lost ground when completely eliminated.
If English blacks score very close to the natives of that island than my theory is shot and I'll be forced to change my mind.
