Honesty-Humility and unethical behavior in adolescents: The mediating role of moral disengagement and the moderating role of system justification

Abstract

Introduction: Honesty-Humility represents the tendency to be fair, genuine, and cooperative in social interactions. Although previous evidence has demonstrated that Honesty-Humility is related to decreased unethical behavior, little is known about the mediating and moderating mechanisms underlying this relationship, especially among adolescents. Based on social cognitive theory and system justification theory, the present study aims to examine the mediating role of moral disengagement and the moderating role of system justification in the relationship between Honesty-Humility and unethical behavior among Chinese adolescents.

Methods: A large sample of Chinese adolescents (N = 2,576, 47% boys; M_age = 17.00 years, SD = 1.07) was recruited from four senior high schools. The participants completed questionnaires regarding Honesty-Humility, moral disengagement, system justification, and unethical behavior.

Results: The findings suggested that Honesty-Humility was negatively associated with adolescents' unethical behavior, and moral disengagement partially mediated this negative association. Furthermore, system justification moderated the mediation model. Specifically, the negative relationships between Honesty-Humility and moral disengagement/unethical behavior were stronger among adolescents who perceive the society as fair.

Conclusion: These findings advance the understanding of when and how Honesty-Humility prevents adolescents from unethical behavior. The theoretical and practical implications of the current study as well as future research directions are discussed.
