Why You So Liddat is a show that explores the mind, our behaviour, and why we are the way we are. We humans love being in groups - whether it's a family unit, a football fan club, or even a religion. Groups give us a sense of identity and belonging. But they're also the main actors behind a lot of conflict in this world. This week, we speak to David to find out why we like being in groups, when groups start becoming toxic, and whether it's time we give up the idea of groups.
