Title: Widely Discredited Junk Science
Review: Anybody considering reading anything by Rushton should first read the following article that appeared in the New York times four years ago: (...)Rushton's ideas have been widely discredited by the entire scientific field looking at human variation and human origins. Among many other points in the article refuting Rushton's ideas:* Researchers have found that, on average, 88-90% of human genetic variation occurs within populations, while the remaining 10-12% is between populations.* The genetic traits that show the most variation between groups (including skin pigmentation and other physical appearance features, and susceptibility to sickle-cell disease and tay-sachs disease) are governed by a very small number of genes.* By contrast, traits such as intelligence, social skills, and artistic talent are governed by thousands of genes, and are therefore not going to show significant variation between groups.
