There has been much talk here about Chanda Chisala's article "The IQ gap is no longer a black and white issue." Much of the article focuses on the Igbo (known also as Ibo), a people who live in the Niger Delta and "are well known to be high academic achievers within Nigeria." In the United... Read More

Great at reading or recognizing faces? You might not do so well on an IQ test.
The English psychologist Charles Spearman was the first to argue that a single factor, called "g," explains most of the variability in human intelligence. When observing the performance of children at school, he noticed that a child who did well in math would also do well in geography or Latin. There seemed to be a... Read More
When geneticist Davide Piffer examined IQ-enhancing alleles at seven different genes, he found that their average prevalence differed among human populations, being highest in East Asians and lowest in Mbuti Pygmies (photo used with author\
My weekly posts are now appearing on The Unz Review( By accepting Ron's invitation, I hope to reach a bigger audience and bring myself closer to other writers in the area of human biodiversity. When people work together, or simply alongside each other, minor differences can be ironed out and major differences narrowed or at... Read More
Robert Plomin on the genetics of various mental traits (source) A Chinese research team is looking for genes that explain why IQ is higher in some people and lower in others: The head of the team, Zhao Bowen, believes this question has not be
The latest issue of Evolution and Human Behavior has an article on paternal investment and IQ. Using a longitudinal dataset of children born in Britain in 1958, Nettle (2008) found a significant positive correlation between a child’s IQ at age 11 and the father’s degree of family involvement. The less a father cared for his... Read More
The October issue of Scientific American has an article on the search for genes that influence intelligence. Twin studies suggest that such genes exist, yet efforts to date have been disappointing for Robert Plomin, a behavioral geneticist at the Institute of Psychiatry in London. That means that there must be hundreds—perhaps thousands—of genes that together... Read More
The New York Times has run an article on genetic research by Dr. David Goldstein of Duke University. His main finding is that most human diseases with a genetic basis are not due to common alleles. They are apparently due to rare alleles that have not been eliminated by natural selection. This seems to argue... Read More
G is general intelligence, a common property we see in the similar test scores that people show for different cognitive tasks. But just what is this common property that makes some people generally smarter than others? There have been attempts to identify g with a specific brain characteristic. Unfortunately, as Anderson (1995) notes: Whatever g... Read More
