While searching around I came across this 2006 paper, which provided scores, based on international assessment tests, for 27 African countries, 11 of which L & V (2012) did not have int. test data for (Benin, Burkia Faso, Cameroon, Chad, Madagascar, Mali, Mauritania, Nambia, Niger, Sengal, and Togo), and 6 of which L & V (2012) had neither international data nor IQ data for (Benin, Burkia Faso, Chad, Mauritania, Niger, and Togo).
This allowed me to create the most comprehensive African IQ data set to date (excel file here). Listed are Malloy’s 2008 IQ estimates (N-weighted, international tests excluded),
L & V’s 2012 IQ estimates, Wichert et al.’s 2009 IQ estimates, Altinok & Murseli’s 2006 Int. test estimates, and L & V’s international test estimates. The last column gives the highest score out of the 5 estimates for each country. The average for 40 African nations comes out to 75. It should be noted that the correlations between some of the estimates were pretty low. Interpret that as you will.
While I was at it, I created a global National IQ excel file with Altinok & Murseli’s estimates and others. Here. If you find any mistakes, let me know.
I should add that most of Altinok & Murseli’s and L & V’s international African test data come from fairly recent studies. Here is some background info on the SACMEQ I, SACMEQ II, and PASEC, which supply most of the data points (based on international assessments). They’re from the mid ’90s to mid ’00s. So, it’s not as if we’re dealing with relics here.
