Episodic simulation reduces intergroup bias in prosocial intentions and behavior.

People frequently feel less empathy for and offer less aid to out-groups in need relative to their in-groups. Most attempts aimed at reducing intergroup bias in helping emphasize group-focused cognitions and emotions. However, little is known about how the sensory properties of intergroup episodes informs intergroup decisions. Here we investigate whether episodic simulation (i.e., the ability to imagine events in a specific time and place) (a) increases participants' general willingness to help, and (b) decreases the difference in prosocial intentions and behavior toward in-group versus out-group targets. Experiment 1 revealed that imagining a helping episode significantly increased self-reported intention to help in-group and out-group targets, and eliminated the gap between groups relative to a control manipulation. Path modeling analyses indicated that the effect of episodic simulation was mediated by the vividness of the imagined episode and heightened perspective-taking for the target. Experiment 2 replicated these findings and ruled out reduced encoding of group membership as an explanation for the effect. Experiment 3 demonstrated that the effect of episodic simulation on prosocial intentions was distinct from the effects of imagining people (or contact with them). Experiments 4 and 5 replicated previous experiments with helping behaviors (i.e., writing in a letter of support to the victim of a misfortune; monetary donation to the person in need). These results shed light on a previously unexplored channel of group debasing and conflict reduction. We close by considering implications for future research at the intersection of episodic and intergroup processes. (PsycINFO Database Record (c) 2020 APA, all rights reserved).
