Data: Are lighter-skinned Asian Indians smarter than their darker counterparts?

As I've done in the last couple posts, I correlated the skin tone of General Social Survey participants with IQ scores -- this time for people whose ancestors are from India.

The sample is small, only 39, but the correlation is impressive: -.40. In plain English, the tendency for lighter Indians to be smarter is fairly strong.

This is the third group in a row (Hispanics, whites, now Indians) that has showed the same positive lightness/IQ correlation.
