I would not rely to much on those IQ statistics. What is an IQ? Just the outcome of a test. Since Alfred Binet started with his ideas about the IQ test it has ben developed (by Lewis Terman, Stanford University). The latest comparing of IQ and races is mainly based on Rushton's studies and research. My question is (I didn't have the time to find that out), who of the different races did he test, where the races of the same educational level? How many did he test?
Anyway, IQ is not the way to succes ipso facto.
