And I mean this, you notice the advantage of reading Slashdot with a +6 troll and flamebait modifier.
Oh, and my opinion: IQ testing is an interesting subject. The method of developing a test actually depends on the predictability of its result, in a way: You have a bunch of people with "known" and different levels of "intelligence", and develop the tests from how well they are able to sort the participants out. Do a search for Alfred Binet if you want to know more.
There may be many reasons for why women are found to be less intelligent than men. One thing is that the tests necessarily are skewed, since they are supposed to measure something we don't know what is, can't define, but still somehow believe we can recognize. If IQ tests show that men are more intelligent than women, then it's also caused by men being perceived as more intelligent than women, and the tests being created with a bias to show this. The science behind IQ tests is rather good, but never objective, since there's no object to measure.
Anyway. If some dork thinks he can be proud of himself, as a man, because the tests show men to be more intelligent than women, or whites more than black, or whatever, he should remind himself that there's probably some black women out there who are more intelligent, and bigger and stronger, than him.
And that's really all there is to say about this.
