Do Justices telegraph their preferences during oral arguments? We demonstrate that Justices implicitly reveal their leanings during oral arguments, even before arguments and deliberations have concluded. Specifically, we extract the emotional content of over 3,000 hours of audio recordings spanning 30 years of oral arguments before the Court. Using only the level of emotional arousal in each of the Justices’ voices during these arguments, as measured by their vocal pitch, we are able to accurately predict many of their eventual votes, while using none of the text or substantive content. These predictions are statistically and practically significant and robust to including a range of controls. Our findings suggest that mannerisms that may be subconscious, such as vocal pitch, carry information that basic legal, political, and textual information do not, and can be used to predict the decisions of even elite political actors.
We present an approach to investigating causal mechanisms in survey experiments that leverages the provision or withholding of information on potentially important mediating variables. The designs we propose can identify the controlled direct effect of a treatment and also what we call an intervention effect. These quantities can be used to address substantive questions about causal mechanisms, can be identified under weaker assumptions than current approaches to causal mechanisms, and can be estimated with simple estimators using standard statistical software. Furthermore, these methods are compatible with a broad range of experimental designs, including survey vignettes and conjoint designs. We illustrate the approach via two examples, one on evaluations of potential U.S. Supreme Court nominees and the other on public perceptions of the democratic peace.
The standard approach in positive political theory posits that action choices are the consequences of preferences. Social psychology—in particular, cognitive dissonance theory—suggests the opposite: preferences may themselves be affected by action choices. We present a formal framework that applies this idea to three models of political choice: (1) one in which partisanship emerges naturally in a two party system despite policy being multi-dimensional, (2) one in which interactions with people who express different views can lead to empathetic changes in political positions, and (3) one in which ethnic or racial hostility increases after acts of violence. These examples demonstrate how incorporating the insights of social psychology can expand the scope of formalization in political science.
