A group that grieves together stays together: Examining the impact of Holocaust Memorial Day in Israel on affective polarization

Affective polarization is defined as the tendency to dislike, distrust, and maintain hostile attitudes towards supporters of other political parties or ideologies. In its extreme form, affective polarization may pose a severe threat to these groups' cohesion, functionality, and existence. The current study explored the role of sadness, elicited by memorial days, in temporarily reducing affective polarization and protecting societies from its destructive outcomes. In a longitudinal study (517 participants), participants were surveyed prior to Holocaust Memorial Day (HMD), during HMD, and after HMD. The findings suggest that affective polarization declined during HMD. This effect was partially mediated by an increase in sadness. It is argued that one main function of memorial days is to harness the power of sadness to maintain cohesion and integrity among national groups.
