Passage: "The 'prisoner's dilemma,' a foundational concept in game theory, illustrates why two purely rational individuals might not cooperate, even if it appears that it is in their best interest to do so. The classic scenario involves two suspects arrested for a crime, held in separate cells, unable to communicate. Each is offered a deal: betray the other and go free if the other remains silent, or receive a reduced sentence if both betray each other. If both remain silent, they both receive a minor sentence. The dilemma arises because from each individual's self-interested perspective, regardless of what the other does, betraying is always the dominant strategy, leading to a suboptimal outcome where both betray and receive a moderate sentence, rather than the optimal outcome where both remain silent and receive a minor sentence. This model has broad applications, explaining phenomena from arms races to environmental degradation." Which of the following situations is LEAST analogous to the 'prisoner's dilemma' as described in the passage?
- ATwo fishermen independently decide to overfish a common resource, leading to the collapse of the fish stock for both.
- BTwo nations decide whether to build up their military, resulting in an expensive arms race where neither gains an advantage.
- CTwo rival companies independently decide whether to lower prices, leading to a price war that reduces profits for both.
- DTwo friends deciding whether to pool their money for a lottery ticket, where only one ticket is purchased, and they split winnings if any.
Show answer & explanationAnswer & explanation
Correct answer: D. Two friends deciding whether to pool their money for a lottery ticket, where only one ticket is purchased, and they split winnings if any.
The prisoner's dilemma involves a situation where individual rational self-interest leads to a collectively suboptimal outcome. Options A, B, and D all fit this pattern: individual decisions (lower prices, build military, overfish) lead to worse outcomes for both parties than if they had cooperated. Option C describes a cooperative venture where two friends agree to share, and while there's risk, their individual decision to pool resources doesn't inherently lead to a worse outcome for both due to a conflict of self-interest in the same way as the dilemma.
Why the other options are wrong
- A. This is analogous: individual self-interest (overfishing) leads to a worse collective outcome (resource collapse).
- B. This is analogous: individual self-interest (building military) leads to a worse collective outcome (arms race).
- C. This is analogous: individual self-interest (lowering prices) leads to a worse collective outcome (price war).
