Abstract
Politically heterogeneous social networks have long been considered as a safeguard against political division. However, in today’s polarized political climate, the effectiveness of cross-partisan interactions in mitigating animosity is increasingly questioned. Prior research emphasizes the importance of hearing-the-other-side through cross-partisan discussions with close ties. We confirm that these discussions still take place and are related to lower inter-partisan animosity. Moreover, we propose a complementary mechanism, seeing-the-other-side, according to which even brief interactions with out-partisan acquaintances serve to reduce distorted views of out-partisans, thereby lowering inter-partisan hostility. Using original data from the United States, we find that both close tie and acquaintance networks display significant political heterogeneity and this heterogeneity is associated with lower partisan animosity. Experimentally, we show that reducing misperceptions by increasing the salience of similarities between in-partisan and out-partisan acquaintances further reduces hostility. These findings highlight the continued relevance of everyday political diversity in tempering partisan divisions and nuance worries about partisan echo chambers.
