People were talking earlier about how diverse Africa is. Well this also applies to cognitive ability. Africa has a massive population, and much of what we know about the mean IQ of large sections of the continent is inaccurate because the scores come from estimates and not direct testing. For those areas directly tested, poor health and infrastructure, and poorly conducted tests that are several decades old at this point, obviously depress scores.
The problem with using the mean score is also that it wipes out all understanding of nuance. Breaking things down by ethnicity might be a little more helpful. Lumping in all of black Africa causes one to miss the fact that there are groups whose mean IQs have already surpassed the white mean. http://www.unz.com/article/the-iq-gap-is-no-longer-a-black-and-white-issue/
I know you're not likely to read all of this, but the main takeaways are:
-- There are differences in mean IQ between individual African ethnic groups that are as large as the difference in European and African means.
-- African and Carribean immigrants score higher than African Americans, so clearly having white admixture isn't helping the latter as racists claim it should.
-- Nigerians in particular are some of the highest achieving people in the UK and US. They score 21.8% higher on the GCSEs than the white mean and have some of the highest levels of educational attainment of all groups. There is a 0.81 correlation between GCSE scores and IQ (where 1 is a perfect correlation and 0 is none).
-- When you break it down ethnically, Igbo Nigerians score higher than even the Chinese. Non-emigrant Igbo also outperform other ethnic groups even in their own country, so their high performance can't be chalked up entirely to selective immigration policies in the UK. Some groups from elsewhere, like Krio and Luganda (among others), also score higher than the Chinese.
-- Racists suggest these are statistical flukes from the far end of the bell curve and that the children of intelligent blacks see their scores regress from the highs of their parents, but that is not what is happening with these ethnic groups.
-- The Yoruba and Igbo (who collectively number nearly 100 million, so they can't each be dismissed as being some random isolated tribe whose success has no larger implications) have lived in the most urbanized part of Africa since the 1100s. Obviously their scores are going to be very different from a mostly rural tribe in, say, central Africa. But the test scores and estimates that form the basis of our present understanding (largely from the 1960s and 1970s) don't really take any of this into account.
-- London schools over the past 15 years have come to outperform other cities around Britain in the GCSEs largely on the backs of the scores of three groups: Chinese, Indians, and Black Africans.
