2373 | The first performer in a contract is handing himself over to an enemy [Hobbes] |
Full Idea: He which performeth first in a contract, does but betray himself to his enemy. | |
From: Thomas Hobbes (Leviathan [1651], 1.14) |
22720 | Two prisoners get the best result by being loyal, not by selfish betrayal [Poundstone] |
Full Idea: Prisoners A and B can support or betray one another. If both support, they each get 1 year in prison. If one betrays, the betrayer gets 0 and the betrayed gets 3. If they both betray they get 2 each. The common good is to support each other. | |
From: William Poundstone (Prisoner's Dilemma [1992], 06 'Tucker's') | |
A reaction: [by Albert Tucker, highly compressed] The classic Prisoner's Dilemma. It is artificial, but demonstrates that selfish behaviour gets a bad result (total of four years imprisonment), but the common good gets only two years. Every child should study this! |
22721 | The tragedy in prisoner's dilemma is when two 'nice' players misread each other [Poundstone] |
Full Idea: The tragedy is when two 'nice' players defect because they misread the other's intentions. The puzzle of the prisoner's dilemma is how such good intentions pave the road to hell. | |
From: William Poundstone (Prisoner's Dilemma [1992], 11 'Howard's') | |
A reaction: I really wish these simple ideas were better known. They more or less encapsulate the tragedy of the human race, with its inability to prioritise the common good. |
