These two kinds of leadership parallel Harvard political scientist Joseph Nye’s distinction between hard power and soft power. I’ve always thought this extremely useful concept would be more widely adopted under different terms – instead of calling it hard and soft, let’s call it hot power and cool power. We’re moving from an era of hot-power leadership to an era of cool-power leadership. Women don’t have a lock on the new leadership. Because the newly valuable skills can be learned, men can adapt, and many are doing so. But don’t be surprised to see more women on lists of effective leaders. In the era of cool-power leadership, they have an advantage.
