Collective punishment depends on collective responsibility and political organization of the target group

What factors determine the willingness to inflict collective punishment upon a group for a misdeed committed by individual group members? This research investigates the effect of collective responsibility shared among group members and the moderating effect of the groupʹs political organization (democratic vs. nondemocratic). Hypothesizing that moral accountability should be greater for democratic offender groups compared to nondemocratic groups, five experiments showed that the positive effect of collective responsibility on support for collective punishment (Experiment 1) was stronger for democratic groups than for nondemocratic groups (Experiments 2–5). A sixth experiment revealed that the moral and social value ascribed to democracy led to higher expectations towards democratic groups, resulting in negative perceptions of the democratic offender group and ultimately in increased collective punishment. The results are discussed in terms of defense strategies of democratic values.
