Power of Strangers

In our cities, we stand in silent buses and tube carriages, barely acknowledging one another. Online, we retreat into silos and carefully curate who we interact with. But while we often fear strangers, or blame them for the ills of society, history and science show us that they are actually our solution. Throughout human history, our attitude to the stranger has determined the fate and wellbeing of both nations and individuals. A raft of new science confirms that the more we open ourselves up to encounters with those we don't know, the healthier we are.
