Across five studies (N = 2,408), we demonstrate the role that perceptions of predictability play in judgments of moral character, finding that people demonstrate a moral preference for predictable, as opposed to unpredictable, immoral actors. Participants judged agents performing an immoral action (e.g., assault) for an unintelligible reason as less predictable and less moral than agents performing the same immoral action, along with an additional immoral action (e.g., theft), for a well-understood immoral reason (Studies 1-4). Additionally, agents performing immoral actions in an unusual way were judged as less predictable and less moral than those performing the same immoral actions in a more common manner (Study 5). The current study demonstrates how immoral actions performed without a clear motive or in an unpredictable way are perceived to be especially indicative of poor moral character. In revealing peoples’ moral preference for predictable immoral actors, we propose that perceptions of predictability play an important, yet overlooked, role in judgments of moral character. Furthermore, we propose that predictability influences judgments of moral character for its ultimate role in reducing social uncertainty and facilitating cooperation with trustworthy individuals and discuss how these findings may be accommodated by person-centered theories of moral judgment and theories of morality-as-cooperation.
