> The findings by Pope and Sydnor (in this issue) are very much in line with stereotypes influencing test performance at the tail. Looking at U.S. data, they find large variation in the gender ratios of 8th graders scoring in the top 75 graders scoring in the top 75th and 95th percentiles of the National Assessment of Educational Progress (NAEP). The test is taken by a sample of children in public schools. Consistent with beliefs influencing behavior, they show that in regions where men and women are viewed as more equal there are smaller gender disparities in stereotypically male-dominated tests of math and science and in stereotypically female-dominated tests of reading.
