There is no doubt that social distancing is the best way to slow the spread of the coronavirus. But the efficacy of social distancing (or really any other public health measure) relies on something much deeper and harder to measure: social solidarity.

“Solidarity,” writes Eric Klinenberg, “motivates us to promote public health, not just our own personal security. It keeps us from hoarding medicine, toughing out a cold in the workplace or sending a sick child to school. It compels us to let a ship of stranded people dock in our safe harbors, to knock on our older neighbor’s door.”

Klinenberg, a sociologist by trade, is the director of the Institute for Public Knowledge at New York University. His first book, Heat Wave, found that social connection was, at times, literally the difference between life and death during Chicago's 1995 heat wave. Since then, he’s spent his career studying trends in American social life, from the rise of adults living alone to the importance of “social infrastructure” in holding together our civic bonds.

This conversation is about what happens when a country mired in a mythos of individualism collides with a pandemic that demands social solidarity and collective sacrifice. It’s about preventing an epidemic of loneliness and social isolation from overwhelming the most vulnerable among us. We discuss the underlying social trends that predated coronavirus, what kind of leadership it takes to actually bring people together, the irony of asking young people and essential workers to sacrifice for the rest of us, whether there’s an opportunity to build a different kind of society in the aftermath of Covid-19, and much more.
