The Smartest Race

No, I'm not a racist, nor am I Caucasian, but I've been reading ramblings that tend to suggest that the two "smartest" races on the planet are the Chinese and Indians. From what I've read, this is mostly based on IQ tests and universal academic performance. I believe this goes under genetics, but which group(s) do you guys think has grown to be intellectually superior and why?

Philosophy? Does voodoo count? Go into a library and see how many "ethnic" philosophers you find.
If you think Greeks are the same race as North-American whites you're deluded, and both China and India have much richer philosophical traditions than the West does.
