Many social interactions are founded on trust, even though a selfish untrustworthy behaviour often provides a larger payoff. Thus, an implicit or explicit reward is often offered as an incentive for fair behaviour. We show that the existence of such an offer is not enough to promote trustworthiness. In fact, counterintuitively, too large rewards may suppress trust, and lowering the intrinsic cost of offering a reward is not sufficient to boost honesty.
