womens are smarter than men
First article.
Any college teacher (at least in the social sciences and life sciences) who has ever paid attention to their own stats know that women do better than men in college classes.
There are all kinds of post hoc explanations given for this like "Girls get better grades because professors are men, nod nod wink wink" and so on. What a load of crap. Women are smarter than men on average, among the smartest people there is no emperical evidence that women are underrepresented, and among the dumbest people in the world .... well, those are mostly guys.
The reasons are obvious and straight forward. The hormones that give some men an evolutionary advantage over some other men also make you stoopid. Any questions? Ask a girl, she'll explain it to you.
And now, finally (or shall I say, "once again") there's proof:
Female students are ahead of men in almost every measure of UK university achievement, according to a report from higher education researchers.
A Higher Education Policy Institute report shows that women are more likely to get places in the top universities and go on to get better grades.
Women also outnumber men in high status subjects, such as law and medicine.
Second article.
Men are smarter than women, according to a controversial new study that adds another cinder to the fiery debate over whether gender impacts general intelligence.
"For 100 years there's been a consensus among psychologists that there is no sex difference in intelligence," said J. Philippe Rushton, a psychologist at the University of Western Ontario, Canada.
Recent studies, however, have raised questions about the validity of this claim, he said. One such study showed that men have larger brains than women, a 100 gram difference after correcting for body size. Rushton found similar results in a study of gender and brain size.
To determine if there was a link between gender and intelligence, and perhaps between brain size and intelligence, Rushton and a colleague analyzed the Scholastic Aptitude Test (SAT) scores from 100,000 17- and 18-year-olds.
G-factor
When Rushton and colleagues weighted each SAT question by an established general intelligence factor called the g-factor, they discovered that males surpassed females by an average of 3.6 IQ points.

The g-factor works like this. "If I tell you the last four digits of my telephone number and ask you to repeat them back to me, that's a low g-loaded memory test," Rushton explained. "But if I then ask you to repeat them back to me in the reverse order, that suddenly requires a tremendous amount more cognitive processing. It is a very high loaded g-item.”
So the g-factor "is really the active ingredient of the test," Rushton said. "It's the single best, most predictive part of the test."
Rushton suspects that the results are due to males having more brain tissue than females on average. "It's a very reasonable hypothesis that you just need more brain tissue dedicated to processing high ‘g' information," Rushton said.
The study, which Rushton co-wrote with Douglas Jackson, also of the University of Western Ontario, is detailed in the current issue of the journal Intelligence.
What do you think about it ?....
