Seriously.

If a westerner wrote an IQ test for a Kalahari bushman, guess who is going to score higher?

I’ve taken sociology and done comparative culture work. IQ tests across border lines to native cultures who’ve never even done a math problem is a stupid comparison.

But look at twin studies. If you take a new born child out of a native environment and grow that child in the west, the IQ test could have some application. But genetics will also say this is the first generation to be exposed to western intellectual concepts.
