Can pride be a vice <i>and</i> virtue at work? Associations between authentic and hubristic pride and leadership behaviors Open
Summary Pride , a discrete emotion that drives the pursuits of achievement and status, is crucial to consider in leadership contexts. Across three studies, we explored how leaders' experiences of authentic and hubristic pride were associat…
Pride: Implications for Leader Behaviors and Effectiveness Open
Although scholars have increasingly recognized the role of affect in leadership processes, research to date has mostly focused on generalized affect rather than discrete emotions. In the current study, we focus on the emotion of pride. Spe…
