The Influence of Descriptive Representation on Support for Judicial Nominees and the US Supreme Court

Abstract

We argue that characteristics of unelected officials directly influence individuals’ perceptions and evaluations of them. These evaluations then have indirect, downstream consequences on evaluations of the institution. To test this, we fielded a unique survey with an oversample of Black Americans after the nomination of Justice Ketanji Brown Jackson to the Supreme Court. Using a conjoint experimental design to randomize nominee race, we find that increased racial descriptive representation elicits more favorable views of the nominee and Court among Black respondents. Causal mediation analysis confirms our theoretical expectation that descriptive representation indirectly influences views of the Court through its effects on views of nominees. The effects we uncover are not confined to co-partisan nominees, indicating that descriptive representation may matter for more than policy reasons alone. Finally, our external validity test suggests these effects generalize beyond our experimental setting, with Black (but not white) respondents equally as supportive of an anonymous profile matching Justice Jackson’s characteristics as they are of Jackson herself.
