in my comment i gave a link to what a fairly large group of university professors, scientists who study, test, and measure intelligence, and what they say they've learned about intelligence. you think you know more, but you don't even investigate or reference what they say, you just think it's the way you think it should be based on ideas you have that you have not tested. not very convincing.

also, cultures don't have iq's, there is no known link to culture.
