War Rewires Moral Values, Study Finds—With Unexpected Group Bonding Effects
Researchers tracking Mosul residents after intense urban combat discovered that exposure to severe violence strengthens both individual fairness concerns and group loyalty—challenging assumptions about how trauma fractures societies. The finding has implications for post-conflict reconstruction, humanitarian aid design, and understanding how populations rebuild after mass violence.
Originaltitel: The Impact of War Exposure on Morality: Evidence From the Battle of Mosul
<p>The Battle of Mosul (2016–2017) was one of the most grueling urban warfare campaigns in recent memory. The fighting quickly concentrated in West Mosul, where civilians prevented by the Islamic State from leaving their homes experienced airstrikes and indiscriminate shelling by government forces. Utilizing the as-if-randomness of severe damage or destruction of people’s homes, this paper examines the impact of war exposure on the endorsement of moral foundations among a large and diverse sample of Mosul residents (<em>N</em> = 1027). Home damage increased binding morality but had a larger impact on individualizing morality, heightening concerns about fairness and protection from harm. A survey experiment in which the sectarian identity of the target was randomly assigned further revealed a strong association between individualizing morality and parochial altruism. Challenging conventional wisdom, both individualizing and binding morality reinforce group cohesion in ways that are functionally adaptive and responsive to the damage wrought by war<em>.</em></p>
