Affective polarization, the extent to which political actors treat each other as disliked outgroups, is challenging political exchange and deliberation, e.g. via mistrust of the ‘political enemy’ and unwillingness to discuss political topics with them. The present experiments address this problem and study what makes people approach, and not avoid, potential discussion partners in the context of polarized political topics in Germany. We hypothesized that intellectual humility, the recognition of one’s intellectual limitations, would predict both less affective polarization and higher approach and lower avoidance tendencies toward contrary minded-others. Across four pre-registered online survey experiments (N = 1668), we manipulated how intellectually humble a target person was perceived and measured participants’ self-reported (topic-specific) intellectual humility. Results revealed that participants’ intellectual humility was consistently negatively correlated with affective polarization. Additionally, intellectual humility of both the target person and the participants was beneficial, and sometimes even necessary, to make participants approach, and not avoid, the target person. Intellectual humility was more important than moral conviction, opinion, and opinion strength. Furthermore, the effects on approach and avoidance were mediated by more positive expectations regarding the debate, and the effects on future willingness for contact by higher target liking. Our findings suggest that intellectual humility is an important characteristic to enable political exchange as it leads to seeing political outgroups more positively and to a higher willingness to engage in intergroup contact. Implications for intergroup contact of political groups as well as ideas for future research are discussed.
