The story of how and why it was so easy to turn normal boys into bloodthirsty, warring tribes (and how those tribes eventually reconciled and became peaceful) can teach you a lot about a common mental phenomenon known as the illusion of asymmetric insight - something that helps keep you loyal to certain groups and alters the way you see outsiders.

Later experiments revealed that if you imagine people's inner lives as icebergs with some things showing above the surface and some things hidden from view, that you have a tendency to believe most of your iceberg is hidden, while everyone else's is mostly visible. Scaled up, you also believe this about the groups to which you belong - yours are nuanced and complicated, theirs are simple and transparent (and dumb).

This asymmetry of insight colors your interactions and decisions big and small. That's what we explore in this inbetweenisode of the YANSS Podcast.
