Dienekes has posted a study that shows that males have an average IQ that is 3.6 points than for females. For years, I have adopted Arthur Jensen's view, as expressed in g Factor, that the sexes have the same general intelligence. But as someone who has taught college students at several institutions over a decade, this view is at variance with my experience. And, of course, most of the intellectual leaders in my field are men. This graph closely matches what I have seen: you can't detect a gender difference among average students, but it becomes more noticeable at higher levels. The ratio of guys to girls at the highest level appears to be perhaps 4 to 1. La Griffe du Lion has documented the considerable gender difference in math, but I have sensed a general intelligence gap in the classroom. I thought maybe it was just bias on my part, but I am beginning to think it is real, and very important at the highest levels. Just take a look at Charles Murray's Human Accomplishment to see how much it matters.
