What Is Game Theory in Layman’s Terms?
Game theory is a branch of mathematics that deals with the study of decision-making in strategic situations, where two or more individuals or groups are involved. It is commonly used in economics, political science, psychology, biology, and other fields to analyze social interactions.
The Basic Components of Game Theory
In game theory, there are four basic components:
- Players: Individuals or groups who are involved in the game
- Actions: The choices that each player can make
- Payoffs: The outcome of the game for each player based on their actions
- Information: What each player knows about the other players’ actions and payoffs
The goal of game theory is to predict how individuals or groups will behave in a given strategic situation. By analyzing the players’ actions and payoffs, game theorists can determine the optimal strategy for each player.
Types of Games
There are several types of games in game theory:
The prisoner’s dilemma is a classic example of a non-zero-sum game. In this game, two individuals are arrested for a crime but cannot communicate with each other. Each individual has two choices: to cooperate with the other person by remaining silent or to betray the other person by confessing to the crime.
If both individuals remain silent (cooperate), they both receive a light sentence. If both individuals confess (betray), they both receive a heavy sentence. However, if one individual betrays while the other remains silent, the betrayer receives no punishment while the other person receives a very heavy sentence.
In this game, the optimal strategy depends on what the other player does. If the other player cooperates, it is best to betray.
If the other player betrays, it is still best to betray. This results in both players betraying each other and receiving a heavy sentence.
The chicken game is another classic example of a non-zero-sum game. In this game, two individuals are driving towards each other on a narrow road and must decide whether to swerve or continue driving straight ahead.
If both individuals swerve (cooperate), they both avoid an accident. If one individual swerves while the other continues driving straight ahead (defects), the one who continues driving straight ahead wins and the swerver loses.
In this game, the optimal strategy also depends on what the other player does. If you think the other player will swerve, it is best to continue driving straight ahead. If you think the other player will continue driving straight ahead, it is best to swerve.
Game theory is a fascinating area of study that has applications in many different fields. By analyzing strategic situations and predicting how individuals or groups will behave, game theorists can determine optimal strategies for each player.
