    One study provides evidence for their claims:

    Men Smarter than Women, Scientist Claims

    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.

    Flawed conclusion

    Bruce Bracken, a psychologist at the College of William and Mary in Williamsburg, Virginia, who was not involved in the new study, said he thinks Rushton and Jackson make a convincing argument for the sample they used.

    "The difference appears to be real," Bracken said.

    But he questions the team's conclusions. "I believe that the differences probably lie in the variables they hadn't considered," Bracken said.

    One plausible explanation is that more females than males decide to go to college and thus take the SAT test. The study did in fact include about 10,000 more females than males.

    "This suggests that more males are deciding to do something else," Bracken said. "It may be that the males who would not have scored as high on the SAT chose not to take it, and they chose another route."

    A more reliable study, he said, would be to match each male with a very similar female and then compare the results.

    The debate goes on

    The findings add fuel to a still smoldering debate ignited by former Harvard President Lawrence Summers, who stated early last year that males have a higher intrinsic aptitude in science and engineering.

    In a letter from Summers days after his controversial statements, he wrote: "Despite reports to the contrary, I did not say, and I do not believe, that girls are intellectually less able than boys, or that women lack the ability to succeed at the highest levels of science. As the careers of a great many distinguished women scientists make plain, the human potential to excel in science is not somehow the province of one gender or another.”

    While Rushton called his results significant, he doesn't think they are a basis for uprooting the field of education.

    "I don't think it has any real implications for education policy or schoolwork," he said. "In fact, females actually get better grades than males.”

    Plus, he doesn't think the IQ difference would show up in everyday activities. "For the vast majority of people in the vast majority of jobs, it really doesn't translate into very much," he said.

    But when it comes to Nobel Prize winners, he said that men could outnumber women 10-to-1. "Where it will really show up is at the very high end of the distribution," Rushton said.

    Rushton has left the door open for opposing views and findings that might contradict his new study.

    "I wouldn't say it's the last word. We really do need more research on it before we can be absolutely certain," Rushton said.

    The brains of men and women are wired differently thats for certain.

    As for intelligence there's still room for debate!

    The primary metric for establishing intelligence is brain size vs body size. Humans have the largest proportion of brain size relative to their bodies. An elephant may have a larger brain, but proportionally, it is much smaller than humans.

    Now the interesting thing is, within humans, men are generally larger than women. The researchers have found that even accounting for the difference in size between men and women, men still have brains that are 10% larger proportionally.

    Could this explain why even in western countries where there is no lack of opportunity for women, there are still very few that choose science or engineering as a profession?

    Where does it mention that men have 10% more brain size ?

    From the article,

    Average brain weight is 1.5 kg according to wikipedia, so the above is ~6.7% difference.

    Apologies, I got the figure from another article, also mentioned here:

    Um, brain size by itself is not that important when it comes to measuring intelligence. Neanderthals have bigger brains than modern humans.

    What's really important is the size of the cerebral cortex.

    well till few decades ago the only work women were assigned to do is just maintaining household so there is no need for them to think a lot.
    but due to recent changes in trends, as women too were taking multi-tasking ex. working housewife they too were becoming smarter day by day

    by the way the highest iq ever recorded is of a woman

    Women do better in certain faculties, men do better in others.

    One isn't superior to the other; just that, they complement and complete each other.

    If you think maintaining household is easy, ask any guy living all by himself.

    And I have seen plenty of women who are working women, and the way they handled the home and office was quite impressive.

    But at the same time I do thnik, men are more creative and expert in any form of work or profession. Best cooks are men, best painters and designers are men, I mean most of the work women are supposed to be better ,men are better than them.

    So it comes down to what level of expertness you are considering while making this comparison. If you are on average level of expertness, women are smarter while if you go to extreme level of expertness, men are smarter.

    I thought twas prefrontal cortex that matters the most ?

    In any case intelligence by itself is not an indicator of success.

    Women are smart, they secretly control men.

    Very good explaination! Their brains deal with different types of work, there are fields in which men's brain work better but in others women's brain work better. That's why man tops in engineering and science subjects while woman easily flirts and cheats that topper. :p

    Yeah ! Men can not give birth, while women can, so men always feel incompleteness hence they easily develop affection with the woman as if she is his own kid, while women await for their own kids, men are just means to get those :p hence they dont care for men's feelings and so they always keep backups :heh:

    The simple solution is to sense it and stand up. I make it a point not to spend in girls. I even ask for return auto fare from them.
