The world of data can be cruel to one's ideological conceits.
Thanks to iSteve.
Update: This article in the Independent goes even further in claiming that there are twice as many men with IQ > 120 than women with IQ > 120.
Dr Paul Irwing is a senior lecturer in organisational psychology at Manchester University. He claims that men are more intelligent than women.
All the research I've done points to a gender difference in general cognitive ability. There is a mean difference of about five IQ points. The further you go up the distribution the more and more skewed it becomes. There are twice as many men with an IQ of 120-plus as there are women, there are 30 times the number of men with an IQ of 170-plus as there are women.
I don't know why this is, all I can say is that we have a huge amount of data.
In my 2005 paper in the British Journal of Psychology we looked at 22 surveys sampling 20,000 university students. In 21 out of the 22 studies males always had an advantage.

The above research appears to fit with work by J. Phillippe Rushton, Richard Lynn, and Helmuth Nyborg. In addition, such research should exonerate Larry Summers, if not for the perverse bias caused by radical political correctness in academic circles.
