Using game‑theory models to explain real‑world politics, economics, and social behavior. Jiang strips away the abstract math and applies concepts like the prisoner’s dilemma, zero‑sum games, and Nash equilibria to everything from dating to nuclear brinkmanship. The idea is that if you can figure out the “payoff matrix” of any situation, you can predict—and even manipulate—the choices of the players. It’s strategy for geeks who want to rule the world.
“Applied Game Theory explains why the U.S. and China are stuck in an arms race: it’s a classic ‘security dilemma’ where neither side can back down without looking weak. Spoiler: the only winning move is to change the game.”

It moves beyond the textbook “Prisoner’s Dilemma” to design auctions, negotiate treaties, price products, or even schedule airport security checks. Practitioners don’t just predict what players will do; they design the rules of the “game” itself to incentivize better outcomes, like creating a market that naturally reduces pollution or a contract that aligns an employee’s interests with the company’s.
Example: “The city used applied game theory to fix traffic. Instead of just adding lights, they made each traffic signal an ‘agent’ in a game, rewarded for keeping cars moving on its road but penalized for creating gridlock on intersecting streets. The signals started cooperating, learning to form ‘green waves.’ They didn’t just react to traffic; they played a city-sized game of optimization and won.”
