On the Origins of Gender Gaps in Education: Stereotypes as a Self-fulfilling Prophecy

Using reading performance data from a randomized controlled trial of 5224 fifth-grade students in East China, this paper provides a novel test of the hypothesis that evoking a gender stereotype creates gender gaps in education through self-fulfilling prophecies. We found that without intervention, boys performed worse than girls did in reading tests. Evoking a gender stereotype by indicating the expected outperformance of girls over boys in reading had a significantly negative effect on boys and an insignificant effect on girls. As a result, the net effect on the gender gap in reading performance was economically important but statistically insignificant. We also found evidence that increased anxiety was likely the underlying mechanism. Finally, a heterogeneous analysis showed that boys from environments with biased gender role beliefs were more susceptible to the intervention.
