There is something wrong with your argument...first you say its statistically proven that white persons have a higher IQ than black persons (which i seriously doubt it was proven unless you got a link to prove it). But yet you dont bring up the statistic of the majority of black people in professional sports compared to white people. And the "black people tend to be raised with a more physical physiology, whereas whites tend to have a more emotional physiology" part doesnt make much sense.
I think that the average black person is more athletic than the average white person from personnal experiences and from watching professional sports. That doesnt mean that its true in all cases.
I didn't bring up a statistic for the majority of black people in professional sports, but I did say that they had a much higher proportion, read the post, also my arguement is on the dot. Have you ever studied psychology. African American studies touches on this subject as well. As do biology courses... As for the studies... any major textbook would do. The average black person is a little stronger and a little faster than the average white person, my arguement doesn't refute this, my arguement states that the reason doesn't lie in the actual race its self. In lamens terms, if it hasn't already been lamens enough, if a million white and black people were raised the same way, trained the same way as they got older, and always ate the same stuff there would be no statistical difference between them on average between the statistics of IQ, Bench, Squat, Mile Times, 40 times, whatever... of course this study could never be done, and so in all actuallity this is a hypothesis. But I'm not on EF to argue theory, I'm here to learn more about how to see the results I'm looking for.
This is a study's results, I don't agree with the claim that the race diferential is largely genetic based, but this shows evidence of the drastic differenc between black and white IQ scores....

This one is fairly interesting...

"The Worldwide Pattern of IQ Scores. East Asians average higher on IQ tests than Whites, both in the U. S. and in Asia, even though IQ tests were developed for use in the Euro-American culture. Around the world, the average IQ for East Asians centers around 106; for Whites, about 100; and for Blacks about 85 in the U.S. and 70 in sub-Saharan Africa." -
