Can Interparty Contact Reduce Affective Polarization? A Systematic Test of Different Forms of Intergroup Contact

We advance interparty contact as a remedy to affective polarization and examine the processes through which interparty contact attenuates the hostility between Democrats and Republicans. We present results from three studies: (1) a survey examining the association between outparty friendships and affective polarization (cross-validated with a representative data from Pew Research Center), and two experiments, testing the effects of (2) vicarious and (3) imagined contact on affective polarization. We find that interparty contact attenuates outparty hostility primarily indirectly, through perceived commonality between the self and the outgroup, and not through the common mediators of contact, anxiety and empathy. We also show that cooperative interparty interactions – whether imagined or vicarious – have limited advantage over simple positive contact (studies 2 and 3), that negative interparty contact exacerbates outgroup hostility by enhancing anxiety and reducing empathy (study 2), and that interactions with one’s political in group are not necessarily polarizing (study 3). These results underscore the differences between partisanship and other social group identities, and have important theoretical implications for the intergroup contact literature.
