From The City Journal:
The New York Times is determined to show that women are discriminated against in the sciences; too bad the facts say otherwise. A new study has “found that girls perform as well as boys on standardized math tests,” claims a July 25 article by Tamar Lewin—thus, the underrepresentation of women on science faculties must result from bias. Actually, the study, summarized in the July 25 issue of Science, shows something quite different: while boys’ and girls’ average scores are similar, boys outnumber girls among students in both the highest and the lowest score ranges. Either the Times is deliberately concealing the results of the study or its reporter cannot understand the most basic science reporting.
Science’s analysis of math test scores only confirms the hypothesis that cost Summers his Harvard post: that boys are found more often than girls at the outer reaches of the bell curve of abstract reasoning ability. If you’re hoping to land a job in Harvard’s math department, you’d better not show up with average math scores; in fact, you’d better present scores at the absolute top of the range. And as studies have shown for decades, there are many more boys than girls in that empyrean realm. Unless science and math faculties start practicing the most grotesque and counterproductive gender discrimination, a skew in the sex of their professors will be inevitable, given the distribution of top-level cognitive skills. Likewise, boys will be and are overrepresented among math dunces—though the feminists never complain about the male math failure rate.
Lewin claims that the “researchers looked at the average of the test scores of all students, the performance of the most gifted children and the ability to solve complex math problems. They found, in every category, that girls did as well as boys.” This statement is simply wrong. Among white 11th-graders, there were twice as many boys as girls above the 99th percentile—that is, at the very top of the curve. (Asians, however, showed a very slight skew toward females above the 99th percentile, while there were too few Hispanics and blacks scoring above even the 95th percentile to compute their gender ratios.)
