What Is Game Theory? Explained In 4 Minutes

Game theory is the study of strategic decision-making, where your best move depends on what everyone else chooses. You’ll learn how the prisoner’s dilemma works, what a dominant strategy is, and how a Nash equilibrium can lock two rational players into an outcome that’s worse for both. I walk through the classic prisoner’s dilemma with actual payoffs, then show the exact same trap in an airline price war and OPEC’s oil quotas. I also cover the real limits of game theory — why people cooperate more than the math predicts, why fairness matters, and why it’s a lens, not a crystal ball. Whether you’re a student, an investor, or just curious how strategy really works, this video gives you everything you need to understand game theory.
