Game Theory: Winning the Game of Life
Summary
This episode defines game theory, distinguishing it from traditional games by focusing on strategic interactions where payoffs depend on others' choices. It covers core concepts like the Prisoner's Dilemma, Nash equilibrium, and the principal-agent problem, illustrating how rationality often leads to suboptimal group outcomes. The discussion extends to real-world applications in business, public goods, and evolutionary biology, while acknowledging the limitations of assuming human rationality in complex, unpredictable scenarios.
