Ingroup glorification, moral disengagement, and justice in the context of collective violence

What aspects of ingroup identification can lead people to resist justice for the victims of their ingroup's mistreatment? In three studies carried out in the United States and United Kingdom, in which participants read reports of mistreatment of prisoners and civilians by coalition troops in the Iraq war, ingroup glorification, but not ingroup attachment or other individual-difference variables, was a key predictor of lesser demands for justice, but only when the perpetrators belonged to the ingroup. This effect of glorification was mediated by two moral disengagement mechanisms focusing on the outgroup: minimization of the emotional suffering of the victims' families and explicit dehumanization of the victim group. These findings further reinforce the difference between glorification and other forms of ingroup identification, demonstrating that glorification is problematic in maintaining and fostering intergroup relations because of its connection to moral disengagement.
