kappa: Could those test inherit some sort of bias as probably most of them are written by men? If women reason differently than men, couldnt it be said they will test differently? A test showing different score for women than men would only be biased if women though the same as men despite disparity in results. More generally, a test biased against women would
underpredict women's real-life performance.
The intelligence tests are scientifically created and calibrated to test for abilities that are fundamental for success in many areas of human endeavor (business, science, technolgy) - math, logic, association and classification, spacio-visual manipulations, etc.
There is no question that women think "differently" than men in many areas and in those those areas they are inferior.
In fact there was found a strong corellation between estrogen/testosteron balance and math/spacio-visual abilities in both men and women. There are plenty of other biological differences documented between brains of men and women that could explain the difference in thinking.
There are no plausible biases that can be offered to explain the difference as an artificial fluke. Women share the same language and culture as men. Women study the same exact subjects. Women in fact have greater motivation and concentration and do better in math and physics and everything else untill subjects get really complex.
One thing to remember though is that not absolute but relative intelligence that is inherited. A normal woman 2 standard deviations from average would have children with average intelligence also 2 standard deviations from average (setting aside regression to the mean) - same as a man.
It's just that in men 2 standard deviations correspond to an IQ of 130 while in women it may be only 125.
So for a man above average marrying a woman as smart as he is means "marrying up" in genetic sense. Especially if she is very feminine (high estrogen/testosteron ratio) - that means her intelligence is more fundamentally genetic rather than a fluke.
Sandman_SBM: Right, wrong... whatever... the perspective is as fascinating as the reactions to it. And that's all that matters here.
