The Math of Strategic Decision Making

Game theory is the study of how rational players make decisions when their success depends on others. It proves that what is best for an individual often leads to a worse outcome for everyone involved.

Originally used to analyze zero-sum games where one person's win is another's loss, this field now models everything from animal behavior to complex computer algorithms. It famously reveals that cooperation can be difficult even when it is logical. By mapping out potential choices, researchers can predict how people will react in high-stakes situations like economics or diplomacy. It is truly the science of why we act the way we do when life becomes a game.
