As someone who dislikes crowds, listener Graham is curious about them. Crowds gather in all sorts of places, from train stations and football matches, to religious events and protest marches. Many of these events are celebratory, but occasionally – such as in Seoul this year – they can become horrific. Is there a science behind how crowds form, move and behave?
To find out, CrowdScience presenter Anand Jagatia speaks to some actual crowd scientists. He learns about the psychology of social identity, which influences everything from how close we stand to others to how we react in emergencies. He hears about the algorithm behind the biggest marathons in the world, and how they ensure 50,000 runners move smoothly through a city on race day. And he explores how research into the spread of rioting can help to stop crowds from becoming a mob or a crush, helping us to navigate crowded spaces as safely as possible.
