This article investigates one causal mechanism that may explain why female judges on the federal appellate courts are more likely than men to side with plaintiffs in sex discrimination cases. To test whether personal experiences with inequality are related to empathetic responses to the claims of female plaintiffs, we focus on the first wave of female judges, who attended law school during a time of severe gender inequality. We find that female judges are more likely than their male colleagues to support plaintiffs in sex discrimination cases, but that this difference is seen only in judges who graduated law school between 1954 and 1975 and disappears when more recent law school cohorts of men and women judges are compared. These results suggest that the effect of gender as a trait is tied to the role of formative experiences with discrimination.You know, the young women today can't possibly . . . understand the pressures of being first . . . Nothing was good enough, and it took me an awful lot of years to realize how good many of the women really were in relationship to the men's talents. I mean, when I think of it, men that were hundreds of places below us in class were getting great jobs and there were no jobs for us.-Judge Ilana Rovner 1
