From a traditional moral point of view, business practitioners often seem overly concerned about the behavior of their peers in deciding how they ought to act. We propose to account for this concern by introducing a mutual trust perspective, where moral obligations are grounded in a sense of trust that others will abide by the same rules. When grounds for trust are absent, the obligation is weakened. We illustrate this perspective by examining the widespread ambivalence with regard to deception about one’s settlement preferences in negotiation. On an abstract level, such deception generally seems undesirable, though in many individual cases it is condoned, even admired as shrewd bargaining. Because of the difficulty in verifying someone’s settlement preferences, it is hard to establish a basis for trusting the revelations of the other party, especially in competitive negotiations with relative strangers.
