Scholars have long sought to resolve whether and to what degree political actor diversity influences the outputs of political institutions like legislatures, administrative agencies, and courts. When it comes to the judiciary, diverse judges may greatly affect outcomes. Despite this potential, no consensus exists for whether judicial diversity affects behavior in trial courts—that is, the stage where the vast majority of litigants interact with the judicial branch. After addressing the research design limitations in previous trial court-diversity studies, the results here indicate that a trial judge’s sex and race have very large effects on his or her decision making. These results have important implications for how we view diversity throughout the judiciary and are particularly timely given the Obama Administration’s over 200 female and minority appointments to the federal trial courts.
