Do members of a majority group systematically shift punishment onto innocent members of an ethnic minority? We introduce an experimental paradigm, punishing the scapegoat game, to measure how injustice affecting a member of one's own group shapes punishment of an unrelated bystander. When no harm is done, we find no evidence of discrimination against the ethnic minority (Roma people in Slovakia).
In contrast, when a member of one's own group is harmed, the punishment 'passed' onto innocent individuals more than doubles when they are from the minority, as compared to when they are from the dominant group.
