The Paradox of Group Conflict: How Stress Influences Bonds and Rivalries

July 15, 2025 - 23:24

Why do violent conflicts between groups persist—even when all sides suffer as a result? Researchers from psychology and medicine at Heinrich Heine University Düsseldorf (HHU) have explored this complex issue, revealing that stress can both strengthen group bonds and exacerbate intergroup conflicts.

The study highlights that when individuals experience stress, they often seek solace and support within their own groups. This phenomenon can lead to increased solidarity among group members, fostering a sense of belonging and shared identity. However, this heightened in-group cohesion can simultaneously intensify feelings of animosity toward out-groups, perpetuating cycles of conflict.

The researchers conducted experiments to observe how stress affects group dynamics, finding that the emotional responses elicited during stressful situations can drive groups to rally together while simultaneously reinforcing negative perceptions of rival groups. This dual effect creates a challenging environment for conflict resolution, as the very stress that unites individuals can also deepen divisions, making it difficult to break the cycle of violence and hostility. Understanding this intricate relationship is crucial for developing strategies aimed at fostering peace and cooperation among conflicting groups.
