The Trait definition of Leadership is centered on qualities, characteristics, and virtues that great leaders have and share. Stogdill contributed remarkably to leadership studies; in the first study (1948), he uncovered the leadership traits after scores (124) on how particular individuals became leaders over a forty-four-year span. The eight leadership traits he unpacked in his first study were: 1. Intelligence 2. Alertness 3. Insight 4. Responsibility 5. Initiative 6. Persistence 7. Self-confidence 8. Sociability. With time, it became clear that an individual does not become a leader merely because they passively possess these traits, i.e., Leadership is not a resource to be had; instead, Leadership is the result of an active dynamic relationship between a leader and the constituency, i.e., the group members, body or the people the leader serves.
