Precommitment can allow decision makers to maintain trust when de-escalating commitment.

= 7,759, all preregistered) reveal an effective communication strategy: precommitment (i.e., a public pledge to change course conditional on a concrete future state of the world). In the presence (vs. absence) of precommitment, observers deemed decision makers who de-escalated commitment as more trustworthy. This effect held across the roles of the decision makers (entrepreneurs vs. established leaders), the relationship with the decision makers (follower vs. third-party observer), contexts (consumer products vs. infrastructure projects), and measures (perceived integrity vs. incentivized behavior). These benefits for integrity were attenuated when the precommitment was to a vague future action or was not conditional on a concrete future state of the world. Finally, results revealed that precommitment can yield a negative externality: undermining perceived confidence and motivation among followers at a project's inception. Altogether, our work provides a nuanced perspective on a communication strategy decision makers can use to align short-term personal incentives (i.e., reputation management) and long-term organizational incentives (i.e., value maximization).
