Who Gets the Credit for Success and the Blame for Failure? On the Links Between Narcissism and Self- and Group-Serving Biases

People often attribute success to themselves and failure to others. Past research indicates that this tendency toward self-serving attributions is pronounced among individuals high in trait narcissism. The aim of this registered report was to re-visit the link between narcissism and self-serving attributions by studying attributions in a group context and by distinguishing between two major dimensions of grandiose narcissism, admiration, and rivalry. We conducted a group study, ( N = 422 participants nested in 54 groups), in which participants of each group were randomly assigned to one of two teams which then engaged in an intergroup competition. In line with our hypotheses, admiration predicted the tendency to take personal credit for success. Contrary to our hypotheses, rivalry did not uniquely predict the tendency to blame others for failure. Instead, admiration uniquely predicted the tendency to attribute negative team outcomes to unfairness of the competing outgroup. Explorative analyses further revealed that both admiration and rivalry were associated with the tendency to attribute negative, rather than positive, team outcomes to chance. Taken together, the findings indicate that narcissism goes along with an increased propensity for self-serving attributions in competitive intergroup settings and that this tendency is mainly driven by the admiration dimension.
