Psychologists have proposed various systems for categorizing the characteristics that make up an individual’s unique personality; one of the most widely accepted is the Big Five model, which rates an individual according to openness to experience, conscientiousness, extraversion, agreeableness, and Neuroticism. Several of the Big Five personality traits have been related to leadership emergence (whether someone is viewed as a leader by others) and leadership effectiveness.

For example, extraversion is related to leadership. extraverts are sociable, assertive, and energetic people. They enjoy interacting with others in their environment and demonstrate self-confidence. Because they are both dominant and sociable in their environment, they emerge as leaders in a wide variety of situations. Out of all personality traits, extraversion has the strongest relationship to both leader emergence and leader effectiveness. Research shows that conscientious people are also more likely to be leaders. This is not to say that all effective leaders are extraverts, but you are more likely to find extraverts in leadership positions. An example of an introverted leader is Jim Buckmaster, the CEO of Craigslist. He is known as an introvert, and he admits to not having meetings because he does not like them.

Another personality trait related to leadership is conscientiousness. Conscientious people are organized, take initiative, and demonstrate persistence in their endeavors. Conscientious people are more likely to emerge as leaders and be effective as leaders. Finally, people who have openness to experience—those who demonstrate originality, creativity, and are open to trying new things—tend to emerge as leaders and tend to be effective as leaders.

There are also some traits that are negatively related to emerging as a leader and being successful as a leader. For example, agreeable people who are modest, good natured, and avoid conflict are less likely to be perceived as leaders. The key to benefiting from the findings of trait researchers is to be aware that not all traits are equally effective in predicting leadership potential across all circumstances. Some organizational situations allow leader traits to make a greater difference. For example, in small, entrepreneurial organizations where leaders have a lot of leeway to determine their own behavior, the type of traits leaders have may make a difference in leadership potential. In large, bureaucratic, and rule-bound organizations, such as the government and the military, a leader’s traits may have less to do with how the person behaves and whether the person is a successful leader.J Moreover, some traits become relevant in specific circumstances. For example, bravery is likely to be a key characteristic in military leaders but not necessarily in business leaders. Scholars now conclude that instead of trying to identify a few traits that distinguish leaders from nonleaders, it is important to identify the conditions under which different traits affect a leader’s performance, as well as whether a person emerges as a leader.
