Is the true self truly moral? Identity intuitions across domains of sociomoral reasoning and age

Adults intuit that positive moral characteristics (e.g., being caring, being honest) reflect a person's true self. The current work aimed to extend research on the true self phenomenon (a) by directly comparing how moral and nonmoral norms are implicated in intuitions about the true self and (b) by examining intuitions about the true self across various age groups (children, adolescents, and adults). Participants from three age groups were presented with scenarios describing people undergoing change and reported the impact of that change on identity. The nature of the change varied in the type of characteristic (moral belief, social-conventional belief, or personal preference), the direction (positive change or negative change), and the target (self or other). Children and adolescents, like adults, judged that changes to moral beliefs were more disruptive to identity continuity than changes to social-conventional beliefs or personal preferences. All three age groups shared the intuition that negative moral change was more disruptive to identity than positive moral change, which is consistent with an understanding of the central role that morally good characteristics play in perceptions of the true self. Although these results suggest continuity between late childhood and early adulthood in understanding of the true self, age-related differences did emerge with regard to the target of the change. Children and adolescents reported that moral changes in others were more disruptive to identity than moral changes in themselves, unlike adults, whose intuitions were perspective invariant.
