Is there any onus upon an audience to accept an offer only where the resulting promise satisfies the norms I have already discussed? Should you decline someone’s offer to promise if you know that she is insincere, or incapable of keeping such a promise? In practice, all sorts of considerations will be in play, depending upon your relationship to the promise-offerer, whether she is a child or adult, the costs and benefits of causing her embarrassment either now or later, the interests of any third parties, and so on.
