The popular media has repeatedly pointed to pride as one of the key factors motivating leaders to behave unethically. However, given the devastating consequences that leader unethical behavior may have, a more scientific account of the role of pride is warranted. The present study differentiates between authentic and hubristic pride and assesses its impact on leader ethical behavior, while taking into consideration the extent to which leaders find it important to their self-concept to be a moral person. In two experiments we found that with higher levels of moral identity, authentically proud leaders are more likely to engage in ethical behavior than hubristically proud leaders, and that this effect is mediated by leaders' motivation to act selflessly. A field survey among organizational leaders corroborated that moral identity may bring the positive effect of authentic pride and the negative effect of hubristic pride on leader ethical behavior to the forefront.Keywords Authentic pride Á Hubristic pride Á Moral identity Á Leader ethical behavior A recurring theme in corporate scandals, such as those at Enron and Olympus, is that leaders were focused on personal gain, while they lost sight of the needs and interests of others (van Gils et al. 2010). This resulted in leader behavior in which the balance of ethics tipped toward egoism at the expense of altruism (e.g., Bass and Steidlmeier 1999). Behavior that demonstrates social responsiveness to the needs and interests of others is generally considered to be ethical (e.g., Eisenberg 2000; Gilligan 1982; Kant 1785/1959), 1 whereas a focus on egocentric needs and a lack of sensitivity to other people's needs is considered to be unethical (Howell and Avolio 1992). Not surprisingly, leaders' unethical behavior is associated with negative outcomes, such as employee workplace deviance (Thau et al. 2009), whereas leaders' ethical behavior is related to positive outcomes, such as increased employee job satisfaction and organizational commitment (Schminke et al. 2005). Given the broad impact that leaders may have on the collective, it is essential to understand the conditions that prompt leaders to behave ethically.Although scientific interest in ethical leader behavior has greatly intensified (e.g., Brown and Treviño 2006;Tenbrunsel and Smith-Crowe 2008;van Knippenberg et al. 2007), ethical behavior has primarily been viewed from a cognitive perspective (Haidt 2003;Reynolds 2006). Unfortunately, this cognitive perspective has been accompanied by a lack of attention to emotive determinants of ethical behavior (Reynolds and Ceranic 2007 In the current paper, we use the term ethical behavior to refer to behaviors in which the needs and interests of others are taken into consideration. As such, we adopt the term ethical behavior in our introduction and discussion section as an umbrella term for the several measures we used in the current paper: selfless behavior, honesty, and ethical leadership.
