http://www.washingtonpost.com/wp-dyn/content/article/2006/10/19/AR2006101901862.html?referrer=emailTelling women they cannot do well in math may turn out to be a self-fulfilling statement.
In tests in Canada, women who were told that men and women do math equally well did much better than those who were told there is a genetic difference in math ability. And women who heard there were differences caused by environment -- such as math teachers giving more attention to boys -- outperformed those who were simply reminded they were female.
The women who did better in the tests got nearly twice as many right answers as those in the other groups, said Steven J. Heine, a psychology professor at the University of British Columbia in Vancouver. "The findings suggest that people tend to accept genetic explanations as if they're more powerful or irrevocable, which can lead to self-fulfilling prophecies," Heine said.
Heine and doctoral student Ilan Dar-Nimrod divided more than 220 women into four groups and administered math, along with reading, comprehension tests conveying different messages about women's math aptitudes. Their findings are in today's issue of Science.
