Replication Data for: No Compromise: Political Consequences of Moralized Attitudes

Evolutionary, neuroscientific, and cognitive perspectives in psychology have converged on the idea that some attitudes are moralized---a distinctive characteristic. Moralized attitudes reorient behavior from maximizing gains to adhering to rules. Here, I examine a political consequence of this tendency. In three studies, I measure attitude moralization and examine how it relates to approval of political compromise. I find that moralized attitudes lead citizens to oppose compromises, punish compromising politicians, and forsake material gains. These patterns emerge on economic and noneconomic issues alike and identify a psychological phenomenon that contributes to intractable political disputes.
