Impacts of Unethical Behavior on Self-Esteem: A Contingent Dual-Process Model.

Abstract

Previous studies have reported mixed findings on how and why unethical behavior affects self-esteem. To address this issue, a contingent dual-process model is proposed and tested. The model postulates a negative impact of unethical behavior on self-esteem through decreased morality, a positive effect through increased competence, and the relative strength of these two paths depending on system-justifying motives. Studies using unethical behavior for self-interest (Studies 1 and 2), involving ingroup interest (Study 3), and measuring (Studies 1 and 3) and manipulating general system justification (Study 2) provide support for the model. By identifying the effects of system-justifying motives and linking the two competing paths, the model reconciles inconsistencies in previous research regarding how self-esteem is influenced by unethical behavior and reveals the underlying mechanism of this association. Accordingly, the current research constructs a motivational and superordinate framework to clarify the dynamic consequences of unethical behavior.
