As far as average IQ scores go, this is what the world looks like. But there are two relevant tests: the Stanford-Binet, and life itself. If a country scored low on IQ but at the same time led the world in Cavorite production, or cured cancer, or built spindizzies, we would say “screw Stanford-Binet”, and we would be right to do so.
Does that happen? Are there countries with low average scores that tear up the technological track? Mostly not – generally, fairly high average IQ seems to be a prerequisite for creativity in science and mathematics. Necessary, although not sufficient: bad choices (Communism), having the world kick you in the crotch (Mongols), or toxic intellectual fads can all make smart peoples unproductive…
Diasporas track. The populations that scored low at home score low in new lands: those that scored high continue to score high. Chinese that entered Malaysia as illiterate tin miners end up doing well in a few generations: Japanese that moved to Brazil to pick coffee are high achievers now.
Is it easy to notice such differences? Well, for ordinary people, it’s real easy. Herero would ask Henry why Europeans were so smart – he said he didn’t know. But with the right education, it apparently becomes impossible to see. Few anthropologists know that such differences exist and even fewer admit it. I’m sure that most have never even read any psychometrics – more importantly, they ignore their lying eyes. Economists generally reject such explanations, which is one reason that they find most of the Third World impossible to understand. I must give credit to Garret Jones, who is actually aware of this general pattern. Sure, he stepped on the dick of his own argument there at the end of his book, but he was probably lying, because he had to. Sociologists? It is to laugh.
Generally, you could say that the major job of social science is making sure that people do not know this map. Not knowing has its attractions: practically every headline is a surprise.
