Towards an Understanding of the Dark Triad, Ethical Fading, and Ethicality of Behavior

We investigate the relationship among the Dark Triad personality traits, ethical fading, and unethical behavior. Our findings suggest that Machiavellianism and psychopathy have a significant relationship with ethical fading such that individuals with high Machiavellianism are more likely to exhibit ethical fading, and individuals with high psychopathy are less likely to exhibit ethical fading. We do not find a significant association between narcissism and ethical fading. In the supplemental analyses, we investigate whether ethical fading leads to more unethical behavior (i.e., fraudulent reporting) and if it mediates the effect of Machiavellianism and psychopathy on unethical behavior. Our findings suggest that, while all the dark traits have a direct effect on unethical behavior, only Machiavellianism has an indirect effect that flows through ethical fading.
