There are documented gender disparities in the legal field. We examined whether gender representation on civil trial teams varied on the basis of (a) the degree of regional gender bias "in the air" and (b) time. We hypothesized that women were underrepresented both on trial teams and in leadership roles within those teams. We predicted that these gender disparities were exacerbated in regions with stronger regional gender bias and that these gender disparities attenuated over time. We coded attorney gender and case outcomes in real civil trials (N = 655). We created regional implicit and explicit gender bias scores based on the year and region of the case using Project Implicit data. Finally, we used order-constrained inference and Bayesian modeling to identify the best-performing models. Overall, women represented only 17% of attorneys at trial and 13% in leadership roles-indicating vast gender disparities. Gender disparities on teams and in leadership roles were more extreme in regions with high (vs. low) regional gender bias (teams: Bayes factor [BF] = 9,182; leadership: BF = 91,667) and improved over time (teams: BF = 6,420; leadership: BF = 3,495). Gender alone best predicted the likelihood of serving in a leadership role (BF = 1,197,397). Female attorneys were grossly underrepresented on civil trial teams. Gender representation on teams, but not leadership roles, has improved slightly over time. Culture may also contribute; women were less represented on trial teams in regions with greater gender bias in the air-particularly in leadership roles. Despite these slight improvements in representation on trial teams over time and in low-bias regions, gender disparities in leadership roles persist over time and levels of regional bias.
