Final answer:
The statement that trait theories of leadership suggest leaders have certain traits more than non-leaders is true. The Five Factor Model, which includes traits like openness and extraversion, is a well-accepted theory in understanding leadership traits, which are also known to be stable and heritable.
Step-by-step explanation:
Trait theories of leadership indeed suggest that certain personality, social, physical, or intellectual traits are more predominant in leaders than in non-leaders. This statement is true. Trait theorists have attempted to categorize and measure these traits to understand leadership better and predict leadership effectiveness.
Among the various trait theories, the Five Factor Model or Big Five is widely accepted today and consists of openness, conscientiousness, extraversion, agreeableness, and neuroticism. Researchers have found these trait dimensions to be relatively stable throughout a person's life and influenced by genetic factors.
Leadership research has evolved over time, identifying the importance of both the traits individual leaders possess and the contexts in which these leaders operate. Furthermore, the compatibility between leadership style and follower characteristics can influence the efficacy of the leader-follower relationship.
