Hi pwagen. Thanks for your reply. When i wrote "that black people do not have the same opportunities to success." , i meant that because of they live in undeveloped countries, poverty, totalitarian regimes, civil wars, they dont find open doors to prove their abilities. So , i didnt wrote about the blacks in America or EU.
Success is not related to skin colour. Success is not related exclusively to intelligence.
In essence, my question is : Suppose you have 1000 whites and 1000 blacks. All raised in the same environment and have similar levels of knowledge. Are the result going to show that whites have higher IQ?
