“and so this is the really big question of what makes it possible for us to cooperate and the answer here at least my answer is is quite surprising it's the ability to invent and believe fictional stories because underneath every large-scale cooperation at the bottom you always find some kind of fict”

Human cooperation is a primary driver of our species' success, relying on language and common knowledge to synchronize actions.

“But also a bunch of people acting together can do a whole lot more than what any individual can do or or a bunch of individuals each doing their own thing without any kind of coordination.”
