I never really undestood African American culture, their greiviances and pain.... now I am begining to. I found this conversation to be deeply hurtful. The facetious attempt to seem unbiased was threadbare. In my mind I could easily imagine these gentlemen in the 18th and  19th century calmly discussing this topic at a slave market.  As an educated African surrounded by other educated, high achieving Africans the idea that race determines intelligence and that somehow my race is in some way  intellectually inferior is insulting. As the number of high achieving and educated Africans grows.... and it is growing I wonder how the conversation will evolve. How will such people attempt to prove themselves superior then?,(reply>), It is based on group averages, not highest IQ cap attainable from birth... Meaning (This is not real data but an example) that for every 1 in 10 East Asian born, 1 will be highly intelligent, for every 1 in 15 Europeans born, 1 will be highly intelligent, for every 1 in 30 Hispanics born, 1 will be highly intelligent, for every 1 in 45 Africans born, 1 will be highly intelligent.<br>And thats what the G-factor and bell curve shows. So of course there will be African geniuses making big contributions to society. But the overall population of them doing that will be smaller as you go down the IQ ladder.
