Jason Malloy has noted (as has Steve Sailer) that the white admixture of genes into the black American population can not explain the discrepancy between the average West African IQ (~70) and that of American blacks (~85). On a tantalizing note, Lynn did some work in England that seemed to show that the South Asian IQ was about 95 [1]-about 15 points higher than the mean in India. The IQ that Lynn gives for Fiji Indians though is about 85. This does not take into account the different streams of migration (I would not be surprised if South Asians in the United States had mean IQs of 110 at least because of the nature of that migration) and possible dysgenic effects. But an optimist can hope that if Third World nations modernize their IQs will rise. I would like to see how the “Celtic Tiger” now fares after 10 years of economic development (Ireland had the lowest IQ in Western Europe at ~90).
[1] The Indians were higher, Pakistanis and Bangaldeshis somewhat lower. Lynn attributed this to the fact that latter groups were more likely to be recent arrivals with a less fluent command of the language. But the East African exile population probably has more social and genetic capital than typical of South Asia.
