Plenty of research has shown that some stereotypes are not only offensive, they can also have a detrimental effect on people's behaviour.
For example, women's maths performance suffers after they are reminded of the stereotype that men are better than women at maths.
Now Armand Chatard and colleagues have taken this line of research a step further by demonstrating that being reminded of gender stereotypes can distort students' memories of their prior exam performance.
An initial study with 73 high school students (34 boys) showed that those students who more strongly endorsed gender stereotypes in relation to maths and the arts, subsequently showed more biased recall of their past exam performance. That is, girls who endorsed the stereotypes underestimated their past maths performance, while boys who endorsed the stereotypes tended to underestimate their past arts performance.
A second study with 64 high school students gave some a highly salient reminder of gender stereotypes - that is, they rated their agreement with statements like "Men are gifted in mathematics" and "Women are gifted in the arts", before rating their own abilities. Others were given what was considered a weaker reminder of gender stereotypes - they rated their own performance first, before evaluating men and women in general. Finally, all the students recalled their past exam performance.
Girls given a more salient reminder of gender stereotypes underestimated their actual past maths exam performance while boys in this condition overestimated their maths performance. No such difference was observed in the weak reminder condition. Regarding the arts, all students overestimated their performance, but among those given a salient reminder of stereotypes, the girls overestimated their arts performance more, and the boys far less.
The researchers said these findings could have real world implications: "It is possible that women are less likely to embrace scientific careers than men because gender stereotypes lead them to underestimate their past achievement."
