Ingroup norms shape understanding of outgroup prosocial behaviors

This research investigated whether ingroup norm moderates the effect of positive or prosocial interactions on the understanding of intergroup prosocial behaviors. Among four experiments in three different cultural samples (U.S. Americans, Kosovan Serbs, and Kosovan Albanians; N = 808), results showed that participants attributed fewer prosocial motives and reported less willingness to accept help when the helper was an outgroup than an ingroup member. However, these effects were weaker or nonsignificant in the tolerant norm condition, as compared to the intolerant norm or control conditions. In addition, participants were more willing to interact with the outgroup (vs. ingroup) helper in the tolerant norm condition, as compared to the intolerant norm or control conditions. Finally, normative expectations, the attribution of prosocial motives to the helper, and the anticipated quality of the interaction with the helper sequentially explained the observed effects. The theoretical and practical implications of these results for intergroup help and intergroup contact literature are discussed.
