So, apparently Lawrence Summers was correct:
Wall Street Journal -- Girls
and boys have roughly the same average scores on state math tests, but
boys more often excelled or failed, researchers reported. The fresh
research adds to the debate about gender difference in aptitude for
mathematics, including efforts to explain the relative scarcity of
women among professors of science, math and engineering.The
latest study, in this week's journal Science, examined scores from
seven million students who took statewide mathematics tests from grades
two through 11 in 10 states between 2005 and 2007.The
researchers, from the University of Wisconsin and the University of
California, Berkeley, didn't find a significant overall difference
between girls' and boys' scores. But the study also found that boys'
scores were more variable than those of girls. More boys scored
extremely well -- or extremely poorly -- than girls, who were more
likely to earn scores closer to the average for all students. The study found that boys are consistently more variable than girls, in every grade and in every state studied
(see crude diagram above - showing distributions where mean
intelligence is the same, but the standard deviation of male
intelligence is greater than female intelligence).
In Minnesota, for example, 1.85% of white boys in the 11th grade hit the 99th percentile, compared with 0.9% of girls -- meaning there were more than twice as many boys among the top scorers than girls.
Of course, Summers did not get in trouble for being incorrect. He got in trouble for saying something he was not supposed to say. And it seems that the media are trying to avoid the same mistake, reporting what they want to believe, and not what the study actually says.
As I write in a post at Climate Skeptic, this is part and parcel of a new post-modernist science, where (as MaxedOutMamma writes) "If a
research finding could harm a class of persons, the theory is that
scientists should change the way they talk about that finding".
