Researchers have been examining ways to promote reconciliation and reduce prejudice between groups that have been in conflict. This is a challenging task, especially in areas affected by violence. Intergroup tensions can be longstanding and may also affect other marginalized communities.

Efforts to address these issues are often hindered by ongoing hostilities and structural barriers. Researchers such as Alexander Guest and others have been studying this topic. Further details on their findings are available, including information on specific countries such as Bosnia and Herzegovina, Cyprus, Moldova, and Ukraine.
