TED-Ed: The sibling rivalry that divided a town | Jay Van Bavel and Dominic Packer

The transcript discusses a family feud in Kanoka that divided the town over shoe brands, illustrating how minor differences can lead to significant social divides. It introduces the minimal group paradigm by Henry Tajfel, which shows that even arbitrary group distinctions can cause ingroup bias. The experiments reveal that social identity plays a crucial role in group bias, as people link group membership to their sense of self. Despite the absence of stereotypes or resource conflicts, individuals still favor their group, highlighting the deep-rooted nature of group bias. The findings suggest that while group identity can foster division, it can also be used to overcome biases if managed inclusively.
