The power paradox is this: we rise in power and make a difference in the world due to what is best about human nature, but we fall from power due to what is worst. We gain a capacity to make a difference in the world by enhancing the lives of others, but the very experience of having power and privilege leads us to behave, in our worst moments, like impulsive, out-of-control sociopaths. How we handle the power paradox guides our personal and work lives and determines, ultimately, how happy we and the people we care about will be. It determines our empathy, generosity, civility, innovation, intellectual rigor, and the collaborative strength of our communities and social networks. Its ripple effects shape the patterns that make up our families, neighborhoods, and workplaces, as well as the broader patterns of social organization that define societies and our current political struggles.
