When we are surrounded by people why do we tend to shun them? Why do we refuse to make eye contact or say hello? And, why do tempers flare on busy city streets?



More and more of the world’s population are moving to cities. As they swell in size our behaviour changes and not always for the better. It is a familiar scene, a busy metro carriage with people pushing and shoving but never saying hello or even making eye contact. Why do cities make us act this way?



To find out we speak to social psychologist Dr Elle Boag about what is happening inside our heads. We ask Marten Sims of the organisation Happy City Lab if buildings can make us rude. We perform the Lost Tourist test to find out just how rude London is.

Olivier Giraud tells us why Parisians never give up their seat to pregnant women on the metro. And, Manhattan manners expert, Thomas Farley defends the city and explains the reason we often have to act the way we do.
