Researching both leader types, Fiedler found that authoritarian (or low LPC) leadership is more effective at two extremes: When the leader is powerful, the task is well defined, and relations are good; or when the leader has little power, the task is poorly structured, and the leader is disliked by the group. Democratic (or high LPC) leadership is more effective when the three conditions are somewhere between the two extremes-when the leader has some power, is moderately liked, and the task is somewhat vague.
