Replication Data for: Congenial messages from politicians reduce affective polarization among citizens

Affective polarization among citizens is often attributed to the harsh rhetoric and personal attacks that politicians direct at one another. However, the influence of elite rhetoric on affective polarization may work in both directions. We theorize that politicians can reduce affective polarization by making positive or respectful statements about their political opponents. A preregistered survey experiment with 2,000 citizens provides strong support for this expectation. Politicians’ congenial messages about their opponents significantly reduce affective polarization on two distinct measures. Specifically, the experimental treatments reduce citizens’ negative emotions towards out-partisans, as well as their desire to socially distance themselves from such out-partisans. The depolarizing effect of such messages does not depend on the political alignment of either the politician or the citizen, nor does it necessarily require high levels of political trust.
