Is there a tendency to act more dishonestly when feeling committed to others? Recent studies have pointed at a so-called group dishonesty shift, with dyads or groups behaving more dishonestly than individuals. However, there is reduced knowledge on the boundary conditions of this shift and effect sizes seem to vary across designs. In order to provide a systematic and comprehensive overview of the nature of this effect and to investigate whether and when commitment indeed results in more dishonest behavior we performed a quantitative review of the literature. Starting with 14116 articles, we identified an overall small to medium effect of commitment on dishonest behavior. We observed that effects varied based on the type of commitment manipulation or how dishonesty was measured. In addition, we found evidence of publication bias in our meta-analyses. The findings suggest that the group dishonesty shift is highly dependent on situational constraints and that more systematic investigations are needed.
