Game theory is the study of strategic interactions between individuals or groups. It provides mathematical models to analyze competition, cooperation, negotiation, and conflicts. Game theory is also a useful framework for predicting behaviors of individuals where everyone is trying to outsmart each other. For example: In blackjack, players share a common opponent (the dealer) but make individual decisions. Inexperienced players often make suboptimal choices, such as flipping another card despite a mathematically strong hand. These “sub-optimal” decisions alter card flow for all the other players which can be frustrating. Dating back to President Trump’s first term, game theory is often cited when trying to explain or understand his unpredictable, sharp departures from established norms.
