An exploration of why we don't talk to strangers, and the wonderful things that would happen if we did.

'In a thrilling, immersive journey across time and continents, Keohane upends everything we thought we knew about the people we don't know' Will Storr, author of The Science of Storytelling

When was the last time you spoke to a stranger?

In cities, we stand in silent buses and train carriages, ignoring each other.
Online, we retreat into silos and carefully curate who we interact with.
In our politics, we are increasingly consumed by a fear of people we've never met.

But what if strangers, long believed to be the cause of our problems, were actually the solution?

With the help of sociologists, psychologists, philosophers, political scientists and more, Joe Keohane sets out to investigate why we don't talk to strangers, and what happens when we do. From enhancing empathy, happiness and cognitive development to easing loneliness and isolation, passing encounters can root us in the world, deepening our sense of belonging.

Warm, witty and profound, this book will make you reconsider how you see others, and in doing so show us how talking to strangers is not just a way to live, it's a way to survive.
