Br J Soc Psychol. 2026 Apr;65(2):e70048. doi: 10.1111/bjso.70048.

ABSTRACT

This study examines motivations for participating in the understudied Indonesian riots of May 1998 targeting the ethnic Chinese minority, using an integrative framework addressing intergroup, intragroup and individual factors. Semi-structured interviews were conducted with 31 participants (26 male, 5 female), all aged over 35 and involved in violent acts during the riots, in which thousands of homes and businesses were looted or destroyed, and hundreds of people were raped or murdered. Thematic analysis revealed motivations at three levels: intergroup (ethnic prejudice, animosity towards security forces), intragroup (conformity, fear of missing out) and individual (thrill-seeking, need for significance, greed, impulsivity). Narratives illustrate how these factors interact within a context of socio-political and economic upheaval. Most participants cited motivations at the intragroup and individual levels, with fewer referencing intergroup factors or reporting a single level of motivation. Conformity (an intragroup factor) was reported by all participants. This research highlights the complex interplay of psychological and social dynamics driving collective ethnic violence.
