Prisoner's dilemma

Prisoner's dilemma illustrates how individual rationality can lead to collectively worse outcomes

The prisoner's dilemma showcases the paradox where two rational agents choosing to defect results in a worse collective outcome compared to mutual cooperation. This paradox highlights the conflict between individual rationality and collective well-being.

Example

In a classic scenario, if both prisoners betray each other, they each receive a moderate sentence. However, if they had both cooperated, they would have received lighter sentences.

Understanding this paradox is crucial for designing systems and policies that encourage cooperation and improve collective outcomes.
