Here are a couple of maps showing average IQ’s by region in the world.
The first map is for the native peoples of the region.
The second map is for the majority who currently reside there.
The maps have some inaccuracies.
For instance, Vietnam should be colored the same color as Europe, as Vietnamese IQ is 99, not whatever Richard Lynn says it is.
Botswana has a lower IQ than the rest of Africa as the native peoples are regarded as Khoisan and not Negroids. The Khoisan IQ is estimated at 54, but that seems too low. For instance, an anthropologist who spent years working with them described the Khoisan as “intelligent.” The map for Papua New Guinea masks a few things. The Papuans of the highlands are said to have low IQ’s of around 64 or so, around the same as Aborigines. Nevertheless, Jared Diamond, who worked extensively with Papuans, felt that they were “intelligent, not stupid.”
So we see once again primitive groups that are regarded as retarded on IQ tests, yet anthropologists who have spent years in the field with them say that they seem intelligent, and not retarded. IQ tests do not appear to be accurately measuring the intelligence of primitive peoples.
While the Papuans of the highlands of New Guinea have an IQ of 64, that of the Melanesians on the coast is much higher, around 84. This is curious as the Melanesians go back almost as far as Papuans, a good 30,000 years. However, they did receive an infusion of Taiwanese genes a few thousand years ago. To what extent this accounts for their higher IQ’s is not known.
The IQ of Native Americans is surprisingly uniform at around 87 or so. It would be nice if we could break it down further by native group per nation and see what we can get out of it. Some say that the Canadian Natives of the far north have higher IQ’s than the Indians of the SW US. And Mexican Indians are said to have IQ’s around 82, which may rise to 92 with the next generation if they come to the US.
African IQ appears low, but that says little to nothing about African-Americans, whose IQ’s may exceed those of Africans by up to 20 points. The higher US Black IQ certainly cannot be explained by White admixture as the racists and hard hereditarians tend to do.
The reasons why US Blacks have become so much more intelligent in the US is as yet unknown. Improved environment, selective (eugenic) breeding and other factors may be involved. Massive increases in US Black skull size along with changes from a more archaic to a more progressive phenotype in the past 100 years were said to be only partly due to nutrition.
Part of the changes were also thought to be genetic. This indicates that US Blacks have been genetically evolving towards a more progressive phenotype and larger heads in the past 100 years. Perhaps US Blacks with higher intelligence and more progressive phenotype have been preferentially selected since 1900. Theories about dysgenic trends in the US Black community are unwarranted and unsupported by the science.
