At its core, game theory assumes players are rational and seek to maximize their "utility" (gain). Every "game" consists of three elements: , strategies , and payoffs .

Interaction in game theory is often defined by the . Named after John Nash, this occurs when no player can improve their outcome by changing their strategy while others keep theirs fixed. It is a state of "no regrets." In complex interactions, players must consider: At its core, game theory assumes players are
The most famous model, the , illustrates the tension between individual and collective rationality. Two suspects are interrogated separately. If both stay silent, they get light sentences. If one betrays the other, the "snitch" goes free while the other gets a heavy sentence. If both betray each other, both get moderate sentences. Rationally, each individual is better off betraying the other, leading to a worse outcome for both than if they had cooperated. This highlights why cooperation is difficult to maintain even when it is mutually beneficial. 2. Interaction and Equilibrium Named after John Nash, this occurs when no
Do players know each other’s payoffs (Symmetric vs. Asymmetric)?
