When leaders perform solitary tasks, do they self-regulate to maximize their effort, or do they reduce effort and conserve their resources? Our model suggests that power motivates selfregulation toward effective performance -unless the task is perceived as unworthy of leaders.Our first studies showed that power improves self-regulation and performance, even when resources for self-regulation are low (ego depletion). Additional studies showed that leaders sometimes disdain tasks they deem unworthy, by withholding effort (and therefore performing poorly). Ironically, during ego depletion leaders skip the appraisal and therefore work hard regardless of task suitability, so that depleted leaders sometimes outperform non-depleted ones.Our final studies replicated these patterns with different tasks and even simply manipulating framing and perception of the same task (Experiment 5). Experiment 4 also showed that the continued high exertion of leaders when depleted takes a heavy toll, resulting in larger impairments later. The judicious expenditure of self-control resources among powerful people may help them prioritize their efforts to pursue their goals effectively.3 How Leaders Self-Regulate Their Task Performance:
Evidence that Power Promotes Diligence, Depletion, and DisdainIn most work groups, leaders direct their subordinates to set aside their own individual goals and motives in order to work toward the common good (van Vugt, 2006;van Vugt, Hogan, & Kaiser, 2008). Task leadership is thus essentially interpersonal. Yet leaders often must perform many tasks themselves, including solitary and even mundane chores. Some of these stem from the leadership role directly, whereas others may come in the course of ordinary life and bear no relation to the leadership role. Faced with demands for such performance, leaders may choose to exert themselves to high levels, or they may slack off or even refuse to perform.The decision is often consequential, insofar as the leader's psychological resources of time, energy, and attention are limited and precious. The present research tested two hypotheses about how leaders would respond to such task demands and regulate their solitary performances.Our first hypothesis was that assignment to a position of power or leadership would generally motivate the person to self-regulate effort so as to perform well. Simply occupying a leadership role would thus motivate people to exert energy at many tasks. Self-regulatory efforts would mostly lead to improvements in performance, even on solitary tasks with little apparent connection to the leader's exertion of power. However, this willingness to work hard would be tempered with a broad sense of awareness of limited resources. Hence our second hypothesis predicted that leaders would show reluctance to exert themselves on tasks that they deem as inappropriate uses of their time and effort. We adopted the term disdain to refer to a leader's withdrawal of effort from performance of a task deemed unworthy of a leader's exertions and to the...
