  Cognitive skills are an important personal attribute that affects career
success. However, colleagues' support is also vital as most works are done in
groups, and the degree of their support is influenced by their generosity.
Social norms enter in groups, and gender may interact with cognitive skills
through gender norms in society. Because these gender norms penalize women with
high potential, they can reduce colleagues' generosity towards these women.
Using a novel experimental design where I exogenously vary gender and cognitive
skills and sufficiently powered analysis, I find neither the two attributes nor
their interactions affect other people's generosity; if anything, people are
more generous to women with high potential. I argue that my findings have
implications for the role of gender norms in labor markets.
