Are women excellent leaders, perhaps even better than men, on average or in some circumstances? To address these issues, researchers first have to answer the question of what good leadership is—what behaviors characterize effective leaders? Does effective leadership consist of the resolute execution of authority, the ability to support and inspire others, or skill in motivating teams to engage in collaborative efforts? All such characterizations of good leadership probably have some validity. As situational theorists of leadership contend (see Ayman, 2004), the appropriateness of particular types of leader behaviors depends on the context—features such as societal values, the culture of organizations, the nature of the task, and the characteristics of followers. Yet, despite this situational variability, leadership has historically been depicted primarily in masculine terms, and many theories of leadership have focused mainly on stereotypically masculine qualities (e.g., Miner, 1993). However, given that leaders' effectiveness depends on context, it is reasonable to think that stereotypically feminine qualities of cooperation, mentoring, and collaboration are important to leadership, certainly in some contexts and perhaps increasingly in contemporary organizations. As I show in this article, these issues are critical to understanding women's participation and success as leaders.
