This does not really say much about race inasmuch as it does about the aftermath of colonization or the correlation between how developed a region is (a marker of which includes literacy rates which increase with access to education, another mark in determining development indexes) and how that region averages when tested on criteria created, valued, and disseminated by the most developed regions.

Putting all of that aside, the notion that the map in question could be useful for coming to any sort of conclusions about race still do not really make much sense given that several East Asian and South American regions are on-par with or even exceed the scores of several European regions. It does, however, provide a little bit of insight into economics. Personally I reject the notion of IQ as an adequate means of assessing a person or group of people's intelligence and instead find The Basic Laws of Human Stupidity much more adequate. Please be intelligent.
