A good lot of women are stupid!

The gaussian distribution of gender-based differences in human intelligence as extrapolated from both child and adult versions of Weschler’s intelligence scale is just a small amount of the substantial psychometric evidence pointing in the direction of tremendous sexual dimorphism in human intelligence. Only somebody possessing the limited intelligence of a lesser evolved and more primitive female central nervous system would assume that the bell curve itself is dimorphic; what the gaussian distribution demonstrates is that the disparity between male and female levels of intelligence can be mathematically substantiated through the rigorous application of non-overlapping analytic geometrical co-ordinates.

Gender-based differences in mental capacity are obviously sexually dimorphic because both traits are unevenly distributed between both genders. There are substantial neuro-endocrinological and psycho-physiological factors, such as higher levels of circulating androgens and greater relative brain size in males, which are responsible for the sexual differentiation in human cognition that leads to men having significantly higher levels of intelligence than females. Just because gender-based differences in human intelligence demonstrate some degree of overlap in no way invalidates the accepted scientific fact that the average male is significantly more intelligent than the average female. For example, male and female levels of aggression also show some degree of overlap, but this in no way invalidates the fact that there is considerable sexual dimorphism in levels of human aggression; gender differences in aggression gravitate around certain statistical polarities which indicate that, regardless of the degree of overlap, men are considerably more aggressive than women. It is the very universality of both higher levels of male aggression and intelligence, within all societies and across all cultures, as well as the substantial body of both neuro-endocrinological and psycho-physiological evidence, which makes them both sexually differentiated traits just as dimorphic as gender differences in genitalia (which also demonstrate some degree of overlap, if one takes such intersexual phenomena as hermaphroditism into consideration).

Expressed another way, one could say that the higher levels of male aggression and intelligence, as well as the male reproductive organs, are all sexually dimorphic traits because the expression of all three is the result of higher levels of circulating androgens within the male body; in contrast, the lower levels of intelligence and aggression in the human female, as well as the female reproductive organs, are sexually dimorphic traits because of the presence of higher levels of circulating estrogens within the female bloodstream.

To assume that gender-based differences in native mental ability do not exist is really an act of Orwellian doublethink; those who do so willfully contradict a large body of scientific evidence to the contrary. Taking the data accumulated by Stumpf and Jackson (1994), if 65% of men are more intelligent than 100% of the female population demographic and 35% of women are more intelligent than the average male, then it is obvious that the average male is considerably more intelligent than the average female by a factor of 30% (65% - 35%), a figure which is by no means statistically insignificant. If there is a 30% higher probability that the average man is considerably more intelligent than the average woman, it becomes virtually impossible to assume that there are no sex-based differences in mental capacity. The only way to safely assume that there are no differences in mental capacity would be if the data indicated that there was a 50% probability of both genders being more intelligent than each other. However, this is not the case; the available data reveals otherwise. Men are significantly more intelligent than women because there is a higher probability that the average man (65%) is more intelligent than the average female (35%).

Consistent with these observations, it is furthermore absurd to deny the existence of gender-based differences in intelligence given the fact that both female brain size and mental capacity decreases rapidly throughout the female life cycle as opposed to the male. The researchers Ho et al (1980) actually uncovered a pattern of massive brain shrinkage as the human female ages. This is especially marked from the age of 45 onwards and is a process of nervous degeneration that is almost unparalelled in the life cycle of the human male.

In addition, the team of Ho et al also discovered that the female central nervous system consists of a much higher ratio of cerebrospinal fluid to actual brain tissue, whereas the male has a higher ratio of brain tissue to cerebrospinal fluid. By confirming that men have bigger brains than women, the researchers make it obvious that the human female is mentally inferior to the intellectually dominant male.

In the final analysis, when it comes to cases such as these, it is probably safe to assume that any woman of supposedly high intelligence is considerably dumber than the average man in the street.
