Can you really reach anyone in 6 steps?
This Veritasium video unpacks the magic of six degrees of separation, showing how a few clever shortcuts and weak ties in our networks make the world surprisingly small. Building on Duncan Watts’ small-world model, Steve Strogatz’s storytelling and Barabási’s hub theory, it uses interactive simulations to reveal how quickly diseases (or ideas) can spread and how preferential attachment gives rise to those “rich-get-richer” hubs.
Along the way you’ll get a taste of the prisoner’s dilemma, see how your own behavior can tweak global connectivity, and find handy sponsor codes (Incogni, Snatoms), chapter timestamps, reference links, and a big shout-out to the Veritasium team and scientific collaborators.
