prisoners dilemma

Betray or trust?

A scenario in game theory where two people acting in pure self-interest produce a worse outcome for both than if they had cooperated.

The classic setup: two suspects interrogated separately could minimize total punishment by staying silent, but each has incentive to betray the other, so both confess and receive harsher sentences.

The dilemma illustrates why rational individual choices can lead to collectively irrational results—applicable to arms races, price wars, and environmental problems where mutual restraint benefits everyone but unilateral restraint invites exploitation.
