| Abstract: | Individuals higher in narcissism have leader emergent tendencies. The characteristics of their personality suggest, however, that their leadership qualities will decrease over time as a function of group acquaintance. We present data from two studies that provide the first empirical support for this theoretical position within a transformational leadership framework. In Study 1 (N = 112), we tested narcissistic leadership qualities in groups of unacquainted individuals over a 12‐week period. In Study 2 (N = 152), we adopted the same protocol with groups of acquainted individuals. In Study 1, narcissism was positively associated with peer‐rated leadership during initial group formation but not later. In Study 2, narcissism was not significantly associated with peer‐rated leadership during initial group formation and was negatively associated with peer‐rated leadership later. In Study 1, transformational leadership mediated the relationship between narcissism and leadership initially but not later on. In Study 2, transformational leadership failed to mediate the relationship between narcissism and leadership throughout the study. Despite enjoying a honeymoon period of leadership, the appeal and attractiveness of the narcissistic leader rapidly wane. This decline is explained in part by their changing transformational leadership qualities. |
