Among human races numerous studies have been made of the comparative weight of White and Negro brains with results that fell within the range of about an 8-12 percent lower weight for the Negro brain.Such studies have been conducted by Bean, Pearl, Vint, Tilney, Gordon, Todd,and others. (23) (27)

In addition to the difference in brain weight, the Negro brain grows less after puberty than the white. Though the Negro brain and nervous system mature faster than the white brain, its development is arrested at an earlier age which limits further intellectual advancement. (22) (27)

The thickness of the supragranular layer (the outside layer)of the Negro brain is about 15 percent thinner, and its convolutions arefewer and more simple, on average, than that of the White brain. (9)

The frontal lobes of the Negro brain, responsible for abstract conceptional reasoning, are smaller relative to body weight, less fissured,and less complex than those of the White brain. (9) (27) (23) (22)

Studies conducted with identical twins raised apart inradically different environments provide conclusive evidence that over-all influence of heredity exceeds that of environment in a ratio of about 3to 1. (41)

Even when Blacks and Whites have the same backgrounds,in terms of family income and childhood advantages, Blacks still have average I.Q. scores 12 to 15 points lower than comparable Whites. This includes cases where Black children have been adopted by White parents. Their I.Q.s may be improved by environment, but they are still closer to their biological parents than their adoptive parents. (3) (15) (26)

Equalitarian ideologists often discount I.Q. test results with the excuse that they are culturally biased. Nonetheless, NO ONE, not the NAACP nor the United Negro College Fund, nor NEA had been able to develop an intelligence test which shows Blacks and Whites scoring equally. (15)(42) (3)

I kept the source markers if anyone needs to see the documentation

The black stats... they have what to do with the OP? Maybe this would best make a new thread titled: If you believe in NAACP intelligence tests, your[sic] an idiot?
