Many self-help books and corporate coaches extol the virtues of the extroverted personality as a desirable quality for business leaders. Bold, outspoken, and charismatic, the extrovert is the stereotypical CEO or board chair. However, recent studies and literature show that this may not necessarily be the only personality type capable of leadership. In fact, some studies suggest that up to 40% of executives have what could be called introverted personalities. Warren Buffett, Bill Gates, and Google’s Larry Page are prominent examples of introverted leaders who have experienced great success.
