Shared suffering predicts prosocial commitment among Turkish earthquake survivors

Previous research suggests that the perception of shared emotion associated with personally transformative events can foster a strong form of social bonding known as 'identity fusion', which motivates pro-group action. Here we test predictions from this model among Turkish citizens and Syrian refugees following the catastrophic earthquakes in Turkey on February 6th, 2023. The lead researcher administered surveys in person to 120 Turkish earthquake survivors in the most heavily affected areas. In line with our predictions, mean levels of identity fusion significantly increased with perceived shared suffering for both Turkish and Syrian groups. Further, identity fusion predicted prosocial commitment, measured by the expressed willingness of earthquake survivors to volunteer assistance to disaster victims. Remarkably, participants were as likely to pledge help to other Turkish earthquake survivors as they were to their own families. This study contributes to a growing understanding of how shared suffering facilitates group bonding and cooperation, both within and across social groups.
