Race and Sex Differences in Intelligence and Personality: A Tribute to Richard Lynn at 80
Helmuth Nyborg (ed.)
Two of the articles are especially illuminating. In one, a North African discusses intelligence tests that were administered among Libyans. It is a beautifully written article on the way that they structured the tests. How do you compile a representative sample of the population? How do you construct the test instrument? Then, having assembled the test results, how do you handle outliers, and ensure that results of the tests represent a normal distribution? How do you demonstrate that they are statistically valid, meeting all of the standard tests for statistical acceptability, and that they are significant - that they represent something real? This is an illuminating tour through the world of statistics in the social sciences. I cannot recall other articles that adhered so closely to the rigorous standards of good practice, and so clearly explained why and what they were doing. The conclusion, incidentally, resulted in no new knowledge. It amounts to no more than a rigorous confirmation of what had long been established, that the average IQ of North Africans is around 81, comparable to the tenth percentile of the British population.
The second one that attracted my attention was the article on sex differences in intelligence. This one involved a lot of structured equation modeling, and confirmatory and exploratory factor analysis. In this one I learned something. The hypothesis is that boys' and girls' intelligences are quite evenly matched up to about the age of 16, but that male IQs continue to grow after that point, ultimately being somewhere around 3 to 5 points above that of females. It is associated with physical maturity. Women achieve their adult growth earlier, while men continue to grow, in cranial capacity among other dimensions. Performance by sex on the different subtests of the Wechsler Adult Intelligence Survey varies, with women leading men on two of the 11 tests. There was quite a bit of discussion about methodology, the ways in which the
