You think that is due to one's DNA? I'd love to see that study.
Again, you think this is due to DNA?
I'm sure that you don't think you are racist...or maybe you'll just admit it. In reality, I'll be generous and suggest that you have about a middle-school level of understanding of correlation and causation and it results in you making blatantly racist statements.
"controlling for SES only reduces the mean Black–White group difference in IQ by about a third, around 5 IQ points. The genetic perspective does not regard this control for SES as being entirely environmental. It holds that the parents’ socioeconomic level in part reflects their genetic differences in intelligence. Moreover, according to the culture-only theory, as Black groups advance up the socioeconomic ladder, their children should be less exposed to environmental deficits and therefore should do better and, by extension, close the distance separating the Black mean with the White. In fact, the magnitude of the mean Black–White group difference in IQ for higher SES levels, when measured in standard deviations, is larger (Herrnstein & Murray, 1994, pp. 286–289). Other nongenetic hypotheses are that standard IQ tests are culturally biased because the test items are not equally familiar and motivating to all groups or that they only measure familiarity with middle-class language or culture. However, despite attempts to equate items for familiarity and culture-fairness, no “culturefair” test has eliminated the mean group difference. American Blacks actually have higher average scores on culturally loaded tests than on culturally reduced tests, which is the opposite to what is found for some other groups such as Mexican Indians and East Asians. (The mean Black–White group differences are greatest on the g factor, regardless of the type of test from which g is extracted; see Section 4.) Moreover, the three-way pattern of mean Black–White–East Asian group differences occurs worldwide on culture-fair reaction time measures, which all children can do in less than 1 s (see Sect"

There are other differences as well. Have you ever noticed blacks are more heavily muscled with lower voices? Blacks also have much higher numbers of prostate issues, wonder why and how it might relate to other issues?
We're all human, diversity means difference though. Why do you people that think you're more accepting of diversity reject difference.
