Traditionally, leaders of organizations have tried to gain a competitive advantage by focusing on talent, experience, and incentives, assuming that if they attract the most gifted and experienced individuals and incentivize them properly, the organizations they lead will succeed at the highest level. However, as Harker observes, these assumptions have not stood the test of time. Effort regularly trumps talent; experience, at times, is nothing more than more of the same; and, surprisingly, incentives may actually reduce performance. Citing new developments in psychology and organizational research, Harker proposes an exciting new alternative, claiming everyone has the capacity to lead well. A leader's legacy is not predicated on how much he does or how smart she is; rather, it is determined by his or her leadership insight-the capacity to develop others. Leadership Insight shares Harker's vision for a better world-a vision catalyzed by leaders who focus their efforts on creating a positive climate that inspires grit, success, and well-being.
