We simulated whether you can really reach anyone in six steps by running network-based models that show how a few random “shortcuts” and weak ties collapse huge social graphs into surprisingly small worlds. Using disease-spread simulations, preferential attachment, and insights from Watts, Strogatz and Barabási, the video unpacks why hubs and random links make six degrees not just a theory but a mathematical inevitability.
Along the way it even ties in the prisoner’s dilemma to show how your own choices ripple through the network—proving that every new connection, however small, can change the game for everyone.
