Things are moving so fast in genetic research on intelligence that one cannot take a coffee break without missing important announcements. By way of small compensation, even the biggest breakthroughs are based on previous breakthroughs, so most stories in science are about a pattern of results rather than a single paper, and that pattern eventually...

In my last post “Even more genes for intelligence”, I alluded to the mysterious Hsu Boundary, and I encourage you to use this phrase as often as possible. Why should other researchers have a monopoly of jargon? The phrase should help you impress friends, and also to curtail tedious conversations with persons who have limited... Read More

In my last post I said: I had no idea that my thesis would receive instant support the following day in a paper which begins with a stirring paragraph, worth quoting in full: Since its discovery in 1904, hundreds of studies have replicated the finding that around 40% of the variance in people’s test scores...

Jim Flynn once observed that no-one was funding research into the genetics of racial differences in intelligence because they feared they would find something. Here is my psychologist’s summary of where we are as regards the genetics of intelligence in general: 10%. That is to say, by poking about in the genetic code researchers can... Read More
