Article about the latest in male-female brain differences.

From an alt right source (The Unz Review) - apparently, they're not afraid to contradict the prevailing orthodoxy.

The takeaway is that men have about 1/4 standard deviation - about 4 points - greater in g (general intelligence) than women.

This study supports the minority position of Lynn and Irwing, that men are about 4 IQ points brighter than women, an across-the-board advantage, plus better spatial ability, and that part of this difference may be attributed to brain size. Here is Prof Richard Lynn lecturing about it: http://www.unz.com/jthompson/sex-lies-and-videotaped-lectures

You will see that male advantage shows up in the Wechsler standardisation samples, though Wechsler will not agree to this being acknowledged in print, though they have passed on the results privately. An odd situation, to say the least.

As usual, a small difference in means has larger consequences at the extremes. If one assumes a 4 point difference straddling the mean, then women will be 98 to men’s 102. Keeping the standard deviations to 15 for both sexes, and setting the cutoff point at IQ 130 then 3.1% of men and 1.6% of women pass the threshold, meaning 65% of the brightest people will be men.

Since this sample showed no sex difference in standard deviations (to the author’s and my surprise) that is as far as I will go with the calculations. However, even without putting in the usually found smaller standard deviation for women, the implication is clear: 65% of intellectually demanding occupations will be taken by men, if entry to those occupations is based only on mental ability. If the bar is set higher at IQ 145, then 70.5% of such posts will be taken by men.

Which just shows how stupid it is to keep trying to get more women into stem, or to have fired Lawrence Summers from Harvard when he spoke of this.
