This site claims:
Let me get this strait, the race = speed question is being based, in part, on a non-white sample size of 44+ people?
BTW, Allan Wells and Marian Woronin run so damn slow.
It’s not credible to claim that whites simply “aren’t trying”, once your at the Olympic level, it’s pretty much given that you try as hard as you can. The popularity argument doesn’t work either, blacks aren’t running at over 100 times the rate of whites which is what would be necessary to produce that sort of result. How is it that there are hundreds of white sprinters at the high school and college level, yet not one has managed to break the 10 second barrier? Is it that sprinting is simply unpopular with white people? Is it that it’s more popular with black people?
Someone remind me what’s the population of the planet again.
Oh yeah, 6 billion+, and of this number, how many go out for track and field, and train to an Olympic level?
Hundreds? out of 6 billion+.
The sample size is too small to tell you anything meaningful.
How many of the greatest sprinters just didn’t know that they were capable of it?
It’s part self selection, part, running, don’t put food on the table.
Sweet Jebus, if had only known that a science geek could run the 100 metres in 9 flat! To think that I wasted all those hours in the science lab in high school, damn you Einstein!
Holy Mao, do you really think I’d be making clothes for Wallmart
in this stinking sweatshop if I knew I could do it in 8.7.
Bill Gates, what a putz, could of been the fastest man in the world, instead of the richest.
Is there any way to explain this apart from racial differences? How else do you explain it? Even if every black person in the world were to train as an Olympic sprinter, such a situation could not occur unless you posit genetic difference.
IF every person in the world were to train as an Olympic sprinter,
we pretty certainly would find the genetic difference.
And I guarantee, it would have NOTHING to do with melanin!
You guys would make lousy horse breeders.

I tell ya Chestnut & Sorrel are the fastest.
Wrong, everybody KNOWS Red Dun’s are statistically the fastest in the world. :wally

Me I’m going to the realraces!
Buy all the winners, hire all the top trainers, let the horses and trainers do what they do best for a decade or two…
Buy myself an island in the pacific, Australia might be nice, and retire!
