Not revenge, but change is sweet: Experimental evidence of how offender change and punishment play independent roles in victims' sense of justice

Abstract

What positive effects do victims gain by punishing their offenders? Previous research suggests that punishment increases victims' justice-related satisfaction only when the offender indicates that they changed their moral attitude and behaviour. However, offender change may increase justice-related satisfaction independently of punishment. So far, it is empirically unclear whether punishment affects satisfaction beyond offender change (e.g. by producing the change), and whether punishment has positive effects on victims that are independent of offender change, specifically how it empowers victims. In two studies, we use a full experimental design to test the unique influence of punishment and offender change on victims' justice-related satisfaction and empowerment. In a third study, we extend the design and additionally test for the effects of assigned versus self-selected punishment. Across three studies (N = 824) with different methodological approaches, we consistently found that offender change alone increased victims' justice-related satisfaction—and this effect was not moderated by punishment. Study 2, but not Study 3, showed that punishment alone empowered victim—and this effect was not moderated by offender change. This indicates that offender change and punishment have independent roles in producing positive effects on victims. Overall, it was offender change and not punishment that made victims feel that justice has been done.
