#43: The Number That Rules Humanity - Robin Dunbar

You only have 150 friends. How do we know that? Because that is Dunbar’s number.

Robin Dunbar is a British anthropologist and evolutionary psychologist at the University of Oxford. His research proved the rule that 150 people is the ‘point beyond which members of any social group lose their ability to function effectively in social relationships.’

Neolithic farming communities, Roman military armies and even global manufacturer Gore-Tex subscribe to Dunbar’s number.

In this episode, we speak to Robin about what his research tells us how about we interact with one another, why maintaining relationships means different things for men and women, and how Dunbar’s number fits in with the law of threes.
