CORE DEFINITION

Five pirates are to distribute 100 gold coins. The rule is: the oldest pirate proposes a distribution plan; if at least half of the pirates agree, the plan passes; otherwise, the proposer is thrown overboard, and the next oldest pirate proposes. Pirates are rational, greedy, and want to survive.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

A classic case of backward induction. By reasoning backward from the situation with only two pirates left, you find that the oldest pirate can propose a seemingly unfair plan that is bound to pass (e.g., 98, 0, 1, 0, 1). It reveals that in a power structure, seemingly weak groups (pirates with higher numbers) actually hold key 'veto votes' that can be used to gain benefits far exceeding their proportion.

Anchor fast decisions

Classic pirate gold distribution: 5 pirates propose in order of seniority to divide 100 gold coins, requiring more than half (including themselves) to agree; using backward induction from the weakest, the most senior can keep the most while still getting approval, overturning intuition.
