Freakonomics y el dilema del prisionero (2)

.
Hace unas semanas comenté que el blog Freakonomics organizó un "concurso" referido a cómo "solucionar" el dilema del prisionero. Si no vieron el post, léanlo, el dilema del prisionero es un concepto central de la teoría de juegos, que a su vez es central en la ciencia política y en las ciencias sociales en general.

Pues bien, ahora, nos comentan los resultados: la pregunta ganadora es "What is the name and address of your most cherished family member?”

Mis respuestas favoritas fueron:

Given that I’m in the Mafia do you realize what my business associates would do to you if you betrayed me? (48)

Do you want to be friends in six months, or have me kill you in 10 years? (234)

Enfoques más "directos" en el mismo sentido. Y otras dos, más crueles:

I’d ask “do you mind if I stay silent?”, pick whoever answers “no”, and then defect (313)

I like the subtle humour of enquiring whether they are economists. But I fail to see how that would change “defecting” being my dominant strategy. Referring to Hitmen, the Mafia or their families seems more helpful, because it essentially changes the game from a one-shot game to a situation where their decision in this game will somehow build their reputation for further games. But true to my Hippie-nature my “question” would begin with discrediting economists (outlining problems with common knowledge, transitivity, second order preferences, …). I would explain how, through convention and trust, our everyday, social interactions are prisoner’s dilemmas and bring up the basically Kantian idea of universalizability, that all games should be played as infinitely long games and that “defecting” puts everything in jeopardy (think Hobbes).Ah, and my question: would you rather live in a world of humans or homi oeconomici? - And then: I’d defect. No, just kidding; I’m really a Hippie (237).

Esta última, si la dejaba en "I'd defect" hubiera quedado perfectamente cruel. Pero, ¿podemos confiar en que de verdad es un hippie?
