(1). There are certain careers that require truly superior intelligence, not just being "smart." Math or engineering professor. Actuary. Patent attorney. Certain IT design fields. (2). The dispersion of male intelligence is wider than the dispersion of female intelligence. So you will find more men with IQ's over 150 than women, and you will find more men with IQ's under 60 than women. Women's variability is not as widely distributed. (3). So you will find that men dominate in those careers where superior intelligence is required. IT IS NOT THE RESULT OF DISCRIMINATION AGAINST QUALIFIED WOMEN. Policy makers who try to craft the "rules" so that women will be represented equally at all levels of success end up making bizarre concessions and allowances to force an unnatural result. Since women dominate the population of colleges and universities, "they" have concluded that their dearth in the aforesaid areas MUST BE THE RESULT OF DISCRIMINATION, and any research that implies that it is natural and not discrimination...well, that research must be suppressed. And what this has to do with housewives eludes me. There are genius car mechanics (men) and there are genius housewives (women) but those people have nothing to do with this discussion.
