Gender Population Distribution v. Traits
Why even an avowedly liberal psychologist, Paul Irwing of the University of Manchester, writing in The Independent, unhappily confessed that there are twice as many men as women with IQs above 120 and 30 times as many over 170.
The lessons of The Bell Curve1 apply to gender equally as they apply to race. If we represent the number of men and women on the vertical axis, and traits on a horizontal axis starting with geniuses and saints on the left and moving to the villains and the drop-outs on the right we would get Gaussian distribution shapes with average traits in the center representing the majority of each sex. The premise being that human traits are random and follow a Gaussian distribution and areas under the curves are equal representing equal numbers of males and females.  See the depiction below contributed to by Eduard Bakalar, Ph.D of the Czech Republic and illustrated by Lloyd Selberg for MDA.
The flatter the curve, the greater the standard deviation from the average. From the shape of the curves we conclude that men have a greater standard deviation than women making the extremes more probable. At both the saints’ end and the sinners’ end men appear in reasonable numbers; women, on the other hand, hardly at all. Professor Camille Paglia put it rather well when she said, “There is no female Mozart because there is no female Jack-the-Ripper.â€Â The Creator and Satan are both widely regarded as males.

This being the case, I often wonder why it is that big media, and particularly female writers and women’s magazines, consider mostly the right end of the men’s line, but concentrate almost exclusively on the left end of the women’s line.
So why it is that maleness and high achievement go so closely hand in hand? Dr. Charles Goodheart at Gonville & Caius College, who has studied the difference in the results between the sexes for 16 years, states quite frankly that it is all a question of testosterone, the male hormone that gives men “forcefulness, aggression, ambition, originality and general push.â€Â Women underachieve because they convert the majority of this hormone to estrogens. The same hormone that produces the yobo also produces the genius. The higher male levels of testosterone with its associated mental effects clearly explain the greater deviations from the norm be it for good or for evil. As both sexes produce testosterone as a precursor to estrogens in females and androgens in males, it should be obvious why gender could become ambiguous in abnormal cases.
