WHEN we think of the qualities we seek in visionary leaders, we think of intelligence, creativity, wisdom and charisma, but also the drive to succeed, a hunger for innovation, a willingness to challenge established ideas and practices. But in fact, the psychological profile of a compelling leader — think of tech pioneers like Jeff Bezos, Larry Ellison and Steven P. Jobs — is also that of the compulsive risk-taker, someone with a high degree of novelty-seeking behavior.  In short, what we seek in leaders is often the same kind of personality type that is found in addicts, whether they are dependent on gambling, alcohol, sex or drugs.
