Is IQ in the genes? The PC hypocrisy of intelligence studies.

oldbrain

We accept that some people are taller than others, or darker- or lighter-skinned, or better at running. We also accept that these differences are due, at least in part, to genetics. Yet there is one area where we continue to insist that there cannot be any innate biological distinction between different people, or groups of people, and that is in our minds. The merest suggestion that there may be hard-wired disparities in intelligence causes the most terrible wailing and gnashing of teeth, even though such physical and mental variations – dictated by genes and environment – are exactly what you would expect in an abundant species that has adapted to just about every corner of the globe.

That taboo, however, may be breaking down. In his new book, the brilliant psychologist James Flynn, of Otago University in New Zealand, has revealed that, for the first time, women (in some developed countries) are systematically outperforming men in standardised tests of intelligence. This contradicts earlier findings which suggested that, historically, men have had IQs that were a couple of points higher – or rather, have performed marginally better on a whole slew of intelligence metrics, which measure subtly different things.
