On social norms and observability in (dis)honest behavior

Transparency and observability have been shown to foster ethical decision-making as people tend to comply with an underlying norm for honesty. However, in situations implying a social norm for dishonesty, this might be different. In a die-rolling experiment, we investigate whether observability can also have detrimental effects. We thus introduce a norm nudge toward honesty or dishonesty and make participants’ decisions observable and open to the judgement of other participants in order to manipulate the observability of people's decisions as well as the underlying social norm. We find that a nudge toward honesty indeed increases the level of honesty, suggesting that such a norm nudge can successfully induce behavioral change. Our introduction of social image concerns via observability, however, does not affect honesty and does not interact with our norm nudge.
