When the future feels increasingly out of our control, how can leaders and organizations make progress? University of Pennsylvania psychologist Martin Seligman, a pioneer in the study of optimism, resilience, and human flourishing, argues that the answer is agency: the belief that we can influence outcomes and create positive change. He defines agency as a combination of three capabilities: efficacy—the belief that you can achieve a goal now; optimism—the belief that you can achieve it in the future; and imagination—the ability to envision possibilities that don’t yet exist. And he explains how leaders can cultivate these qualities in themselves and their organizations, how managers can help employees overcome catastrophizing, and what AI can—and can’t—do when it comes to one of the most important human capabilities: imagination. Seligman is the author of Agency: The Psychological History of Human Progress.
