Short Stuff: Dunbar's Number

This episode explores the fascinating concept of "Dunbar's Number" — the idea that there's a cognitive limit to how many meaningful relationships we can maintain, supposedly around 150 people. Josh and Chuck dive into British anthropologist Robin Dunbar's research on primate social groups and how he extrapolated those findings to humans, discovering a surprising pattern of concentric social circles based on multiples of five. They discuss how this number has held up (or hasn't) in various studies, what it means in our social media age, and why understanding social network limits actually matters for fields like demographics and economics.
