ObjectiveAt U.S. Supreme Court oral arguments, female attorneys are more likely to be interrupted than their male counterparts under some conditions. This makes it difficult for women to effectively construct a narrative and substantively impact case law. While existing work conceptualizes gender as a binary, I draw on recent work stressing gender is performative to deesentialize gender and explore how attorneys’ compliance with gender norms and subtle expectations about men's and women's behavior in a host of contexts, predicts interruptions at oral arguments.MethodsVia quantitative textual analysis of all oral arguments from 2004 to 2019 where one attorney argues for the petitioner and one for the respondent, I examine the extent to which gender norm compliance predicts interruptions.ResultsI find both male and female attorneys are interrupted more frequently when their oral arguments are not gender normative. Thus, an argument that is successful for a male attorney is not necessarily successful for a female attorney, and vice versa.ConclusionMy results underscore female attorneys are not less successful as a matter of course; attorney success is driven by attorney compliance with gender norms. This work also raises a number of normative questions I encourage future scholars to explore.
