The Power of Strangers

Book summary

Joe Keohane is a journalist who has worked as a senior editor at Medium, Esquire, Entrepreneur, and Hemispheres. His writing – on subjects as diverse as travel, social sciences, business, and tech – has appeared in New York magazine, the Boston Globe, the New Yorker, Wired, Boston magazine, and the New Republic.

Human history has long been shaped by a fear of strangers, a trait that has persisted into modern times, fueling cultural and political divides, isolation, and loneliness. Despite this, humans are inherently social beings, and research shows even brief interactions with strangers can enhance happiness and well-being. While societal shifts like increased mobility, globalization, and technology have distanced us, our evolutionary success depended on cooperation with outsiders. By embracing curiosity and cosmopolitanism—valuing and engaging with differences—we can rebuild connections. Small talk, breaking conversational norms, and showing genuine interest are simple yet powerful tools to foster meaningful interactions, countering the growing disconnection in our increasingly digital and solitary world.
