This chapter discusses several theories of leadership: 1) Trait theories propose that leaders possess certain innate personality traits, but research has found no universal traits and traits may better predict behavior in weak situations. 2) Behavioral theories focus on specific leader behaviors that differentiate leaders, such as consideration for subordinates and initiating structure. 3) Contingency theories propose that effective leadership depends on matching a leader's style to situational factors, such as the leader-member relationship and task structure. 4) Situational theories like Hersey and Blanchard's suggest leaders should adapt their directive or supportive style based on follower readiness.
