Abstract

This study investigates whether and how natural disasters affect intergroup perceptions, particularly focusing on subjective expectations for dependability on other groups in emergencies. We conduct a household survey in Central Sulawesi, Indonesia, which has experienced religious conflicts and was heavily hit by the 2018 Sulawesi earthquake. Our estimation results from the survey data indicate that individuals who suffered from the earthquake exhibit higher expectations for access to emergency support from other religious groups in the future. As a possible mechanism of this change, we show that the direct and indirect experience of actual cooperation between groups after the earthquake contribute to the higher expectations of sufferers. We also find heterogeneity in the effect of the earthquake on intergroup perception, depending on, for example, the types of damage and past experiences.
