Why do we fight? It’s a seemingly simple question, but it turns out the answers are surprising, deep and crucial to understanding our world. Considering how costly any conflict is in lives and money, why do wars happen at all? This is one of those episodes that will change how you view some of our most important issues, from the war in Ukraine, to understanding gang fights, and even a possible conflict with China.

We’re taking the week off to work on some truly special episodes coming out in the next few weeks, but thought this was a perfect opportunity to re-share one of our episodes that we think is an absolutely must listen. So please enjoy, and we’ll see you next week for an all new Big Brains.
