My new feature for The Atlantic magazine is called "The Anti-Social Century." It's a long article that revolves around a simple point: Americans are now spending more time alone than ever. This surging solitude is changing our personalities, our politics, our culture, and our relationships. On this episode, University of Chicago psychologist Nick Epley joins the show to talk about why aloneness matters. We talk about his research on relationships and solitude, on why we need people in our lives, and why sometimes we disregard or misunderstand that need, and why "social fitness" is so critical to a good life.
