When people have conflicting goals, they sometimes use intentional misunderstandings (loopholes) to get around direct defiance. Both adults and children expect exploiting loopholes to be less costly than non-compliance (Bridgers et al., 2021; Bridgers et al., 2023; Qian et al., 2023). However, the mitigating effect of loopholes may not hold if they are used to dodge a moral obligation. Here, we replicated the finding that loopholes are less costly than non-compliance in neutral contexts, but found that loopholes were as bad as non-compliance in moral contexts (Experiment 1, N = 360). We then directly compared the behaviors to see if, in moral contexts, exploiting a loophole might be even worse than non-compliance (Experiment 2, N=150). We replicated the finding that loopholes are more exonerating in neutral than moral contexts, and that moral context has a differential effect, but did not find a reversal (Experiment 2, N=150). Finally, we assessed three negative indirect costs of loopholes (blame, permissibility, and offense) and again found a differential effect of moral context (Experiment 3, N = 453). We discuss why using loopholes in moral violations may be uniquely unacceptable.
