Leadership is both a research area and a practical skill encompassing the ability of an individual or organization to "lead" or guide other individuals, teams, or entire organizations. The literature debates various viewpoints: contrasting Eastern and Western approaches to leadership, and also (within the West) US vs. European approaches. US academic environments define leadership as "a process of social influence in which a person can enlist the aid and support of others in the accomplishment of a common task". Leadership seen from a European and non-academic perspective encompasses a view of a leader who can be moved not only by communitarian goals but also by the search for personal power. Studies of leadership have produced theories involving traits, situational interaction, function, behavior, power, vision and values, charisma, and intelligence, among others ¿¿¿ Lewin's Leadership Styles ¿¿¿ In 1939, a group of researchers led by psychologist Kurt Lewin set out to identify different styles of leadership. While further research has identified more distinct types of leadership, this early study was very influential and established three major leadership styles. In the study, schoolchildren were assigned to one of three groups with an authoritarian, democratic or laissez-faire leader. The children were then led in an arts and crafts project while researchers observed the behavior of children in response to the different styles of leadership. The researchers found that democratic leadership tended to be the most effective at inspiring followers to perform well. Let's take a closer look at the three styles Lewin identified: ¿¿¿ Authoritarian Leadership (Autocratic) ¿¿¿ Authoritarian leaders, also known as autocratic leaders, provide clear expectations for what needs to be done, when it should be done, and how it should be done. This style of leadership is strongly focused on both command by the leader and control of the followers. There is also a clear division between the leader and the members. Authoritarian leaders make decisions independently with little or no input from the rest of the group. Researchers found that decision-making was less creative under authoritarian leadership. Lewin also concluded that it is harder to move from an authoritarian style to a democratic style than vice versa. Abuse of this method is usually viewed as controlling, bossy, and dictatorial. Authoritarian leadership is best applied to situations where there is little time for group decision-making or where the leader is the most knowledgeable member of the group. The autocratic approach can be a good thing when the situation calls for rapid decisions and decisive actions. However, it tends to create dysfunctional and even hostile environments, often pitting followers against the domineering leader. Participative Leadership (Democratic) ¿¿¿ Lewin s study found that participative leadership, also known as democratic leadership, is typically the most effective leadership style. Democratic leaders offer guidance to group members, but they also participate in the group and allow input from other group members. In Lewin s study, children in this group were less productive than the members of the authoritarian group, but their contributions were of a higher quality.
