Prelims level: Prisoner's Dilemma
Mains level: Read the attached story
Central Idea
- Defence Minister invoked the concept of the “Prisoner’s Dilemma” to emphasize the importance of international collaboration over competing interests.
- He highlighted the need for countries to find solutions that promote cooperation, trust-building, and risk mitigation in international relations.
What is the Prisoner’s Dilemma?
- Game Theory Basis: The Prisoner’s Dilemma is a renowned concept in Game Theory, a scientific branch that studies decision-making in various scenarios.
- Complex Decision-Making: It illustrates that real-life decisions involve complexity and uncertainty, and outcomes depend on the actions of others.
- Paradox of Conflict: When applied to international relations, it reveals situations where countries engage in actions, such as arms races, driven by mutual fear and mistrust.
Prisoner’s Dilemma Scenario
- Crime Investigation: Imagine two individuals, A and B, facing questioning for a crime without strong evidence.
- Police Offer: The police offer them a choice:
- If one implicates the other, the informant goes free, while the implicated receives a 15-year jail term.
- If both stay silent, both serve one year in prison.
- If both confess, they each get 10 years.
Prisoner’s Dilemma Matrix:
A Stays Silent | A Confesses | |
B Stays Silent | A: 1 year, B: 1 year | A: 15 years, B: 0 years |
B Confesses | A: 0 years, B: 15 years | A: 10 years, B: 10 years |
Dilemma and Decision
- Optimal Outcome: On the surface, staying silent seems best, resulting in both serving just one year in prison.
- Uncertainty: However, if one stays silent, they risk a 15-year sentence if the other implicates them.
- Paradox: To avoid the maximum penalty, confessing becomes the rational choice if trust in the other’s silence is uncertain.
- Cooperation Ideal: The best outcome lies in cooperation, where both prisoners stay silent, serving only one year.
Real-Life Applications
- Business Strategy: Similar dilemmas occur in business, such as price wars between companies selling identical products. Cooperation to maintain sustainable pricing can lead to healthier profits.
- Geopolitical Agreements: Countries can avoid ruinous arms races and protect their economies by establishing ground rules in geopolitics, fostering cooperation over competition.
