"These stereotypes discourage women’s pursuit of many prestigious careers; that is, women are underrepresented in fields whose members cherish brilliance (such as physics and philosophy). Here we show that these stereotypes are endorsed by, and influence the interests of, children as young as 6. Specifically, 6-year-old girls are less likely than boys to believe that members of their gender are 'really, really smart.' Also at age 6, girls begin to avoid activities said to be for children who are 'really, really smart.' These findings suggest that gendered notions of brilliance are acquired early and have an immediate effect on children’s interests."
