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?

Asians and Indians tend to be slightly smarter when compared to Caucasians, but that's usually because the comparisons that most often take place are done in classrooms in 'caucasian' countries. Asian and Indian families value their children's educations more highly than do caucasians, and push their children harder to succeed.

Also they are genetically a little smarter too. Only on average, and it's hardly noticeable except that we get above-average intelligence Asian students (for instance) attending our schools.
