Trustworthiness and Ideological Similarity (But Not Ideology) Promote Empathy.

The current highly polarized U.S. political culture impedes people's ability to live and work together effectively. Here we examine one factor that may play a role: selective empathy based on shared political ideology. Across seven studies ( = 3,476), participants read about a hypothetical politician and his political ideology, trustworthiness, or both. Participants reported their empathy for the politician after learning he was fined (Studies 1-6) or injured (Study 7). When trustworthiness alone was manipulated, liberals and conservatives expressed similar levels of empathy, with greater empathy for the more trustworthy politician. However, when the politician's ideology alone was manipulated, participants reported greater empathy for the politician who shared their ideology. When trustworthiness and ideology were manipulated, selective empathy was observed when the politician was trustworthy. Participant ideology alone had little effect on empathy. The results suggest that empathy is sensitive to both trustworthiness and ideological match, but not ideology itself.
