What seems oddest to me about the claim that black dominance of certain sports at the professional level can be significantly and confidently attributed to genetic differences is how drastically the disproportionality jumps between the college and pro levels.
Frinstance: Blacks comprise only about 12% of the US male population, but 52% of NCAA Division I football teams and nearly 68% of NFL players. The NFL recruits less than 2% of the college players every year.
If we assume that at the elite levels of NCAA Div I and the NFL, competition ensures that teams will overwhelmingly consist of the absolute best players available who all strive equally hard to be chosen, and the different outcomes are therefore due to inter-racial genetic differences in innate ability, then the stats look rather peculiar.
First off, given that there are about seven white males for every black male in the US, then under our assumptions, the nearly even 52/48% racial split at the NCAA level implies that blacks are innately on average about seven times as likely as whites to be capable of top-college football play. That’s a pretty hefty genetic advantage.
With a disparity like this, it seems clear that the only reason there are even as many white college footballers as there are is because the absolute number of blacks is so much smaller. If the US had equal numbers of black and white males, we would expect to see only about one out of every eight of the top college football players being white, rather than four out of every eight as at present.
That implies that on average, three-quarters of the present white NCAA players are inferior in football skills to their black counterparts. If there were equal-sized pools of blacks and whites for the colleges to choose from, three-fourths of today’s white players would be off the team.
But wait a minute. That suggests that the ratio of the really top-level college players on the existing teams ought to be about 4:1 black:white, rather than about 1:1. After all, the NFL is selecting only about 2% of all college players: they can afford to pick the very best rather than having to fill up with makeweights as the college teams do. When the NFL chooses the creme de la creme for the pros, they ought to end up with about four black players for every white one.
But the actual split is more like 67/33%, or about two black players for every white one. Under our assumptions of true meritocracy and innate ability differences, white players are actually vastly and inexplicably overrepresented in the NFL for their average ability level.
Something ain’t right here. The naive assumption of differences in performance outcomes being due to innate genetic ability differences between racial categories is not leading to a statistically consistent conclusion.
