Have you ever broken up a fight? Or pushed someone out the way of an oncoming vehicle, only to be hit by it yourself? Most of us probably haven’t taken as many risks as listener Alix, who has put herself in peril to save strangers on several occasions, and she wants Crowdscience to investigate why. At a time when medical professionals have to weigh up the personal dangers of working on the frontline of the Coronavirus crisis, it’s a particularly timely question. Marnie Chesterton finds out why it’s a good thing that children push the boundaries of what’s safe during playtime, because it makes them less anxious adults. And she questions the existence of the so-called bystander effect, discovering how evolution has ensured we’re a much braver species than we sometimes give ourselves credit for. But she hears from some social scientists who say there’s no such thing as a ‘hero’, however likely they are to intervene to help others.
