Viewers of popular television series like Numbers and Sherlock are probably familiar with how logic is used to resolve mysteries. The protagonists of the series use a form of game theory to describe, explain and predict behaviour, usually, of socially deviant people.
Game theory has been described as the science of strategy. A relatively new discipline, it deals with human transactions. It assumes that everyone who comes to a transaction is a rational actor who puts their interests first before others and that the transaction is utility maximising. Game theory can be used to improve strategic decision making.
