What personality type is more likely to succeed in a leadership position? If you go by popular culture — television, movies, and books written by hero CEOs — you might think extroverts are natural leaders. Research summarized in an excellent article published by Wharton suggests a more nuanced answer.
Employees who are proactive and eager to have their ideas considered will be more productive with an introverted leader, who has the humility and patience to accept employee feedback. Extroverted leaders seem able to get more from passive, less group-oriented employees. This may explain part of a common business mistake, promoting a top salesperson into management. The extroversion that made the salesperson so successful may make her an inappropriate leader of other extroverts.
As a leader, know thyself and select followers that complement your style. As a business executive, consider the personalities of the people to be led when selecting their supervisor. If you already have an extrovert in charge of a group of proactive employees consider some executive coaching to help the extrovert become a better listener and more receptive to the ideas of others. If you have an introvert in charge of a department full of passive people you may need to find some other ways to motivate them to exert themselves and bring useful new ideas forward.
