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?

>Note that they are worse than whites on verbal IQ (the type that correlates most with wealth and success).

But also the one most ruled by cultural upbringing - Asian languages are so different from ours that the way their very brains are wired (language is a huge part of the way the mind works) means those tests will not be so suitable for them.
