Based on the Routine Activity Theory (Cohen & Felson, 1979) and the Social Identity of Deindividuation Effects Model (Postmes et al., 1998), it was hypothesized that perpetrators would be less likely to cheat when there are witnesses present compared to not present, and when the witnesses are part of the in-group compared to the out-group. A third hypothesis postulated public self-awareness as a mediator in the relation between group membership of the witnesses and cheating behavior. The hypotheses were not supported by the data of the current study. It is theorized that the ostensible witnesses in the online experiment were perceived to be insufficiently interactive, resulting in less accountability for the perpetrator. Recommendations are provided for future research to build on these findings.Show less
