Many studies searched for a limited set of personal attributes, or traits, which would make someone be viewed as a leader and be successful as a leader. Some traits that are consistently related to leadership include intelligence (both mental ability and emotional intelligence), personality (extraversion, conscientiousness, openness to experience, self-esteem), and integrity. The main limitation of the trait approach was that it ignored the situation in which leadership occurred. Therefore, it is more useful to specify the conditions under which different traits are needed.

When researchers failed to identify a set of traits that would distinguish effective from ineffective leaders, research attention turned to the study of leader behaviors. Leaders may demonstrate task-oriented and people-oriented behaviors. Both seem to be related to important outcomes, with task-oriented behaviors more strongly relating to leader effectiveness and people-oriented behaviors leading to employee satisfaction. Leaders can also make decisions using authoritarian, democratic, or laissez-faire styles. While laissez-faire has certain downsides, there is no best style, and the effectiveness of each style seems to vary across situations. Because of the inconsistency of results, researchers realized the importance of the context in which leadership occurs, which paved the way to contingency theories of leadership.

The contingency approaches to leadership describe the role the situation would have in choosing the most effective leadership style. Fiedler’s contingency theory argued that task-oriented leaders would be most effective when the situation was the most and the least favorable, whereas people-oriented leaders would be effective when situational favorableness was moderate. Situational Leadership Theory takes the maturity level of followers into account. House’s path-goal theory states that the leader’s job is to ensure that employees view their effort as leading to performance, and to increase the belief that performance would be rewarded. For this purpose, leaders would use directive-, supportive-, participative-, and achievement-oriented leadership styles depending on what employees needed to feel motivated. Vroom and Yetton’s normative model is a guide leaders can use to decide how participative they should be given decision environment characteristics.
