I suppose Iraqi detainees are flourishing down at Guantanamo too

Blacks dont have difficulty succeeding in America.

No more difficulty than one would expect when your culture is taken away and you are treated as inferior subhumans for generations and then forced for further generations to live in conditions of poverty, crime, lack of eduction and proper nutrition and the lack of a supportive and well educated two parent environment.

An IQ test does not measure intelligence the way a ruler measures height (absolutely), but rather the way a race measures speed (relatively). For people living in the prevailing conditions of the developed world, IQ is highly heritable; however, a very large percentage of blacks do not live in the "prevailiing conditions".

Alfred Binet and his colleague Theodore Simon created the Binet-Simon scale in 1905, which used testing to identify students who could benefit from extra help in school. Their assumption was that lower scores indicated the need for more teaching, not an inability to learn. This interpretation is still held by some modern experts. Notably, Binet himself made no claim that his test properly measured intelligence.
