Jeremy Bornstein proposes a party game/Prisoners' Dilemma variant called "I Eat Poo," in which the players pass their phones to their left and invite the player there to type (but not send) an embarrassing message into their own Twitter account. Phones are handed back and each player gets to decide whether to allow the message to be posted, or to forfeit $20 to the message-writer; the phones are handed back to the message-writer, and the hand-over may also include a covert $20 payoff. The climax comes when the final accounting is made: if everyone has paid $20, or no one has paid $20, then nothing happens (the messages aren't posted). Otherwise, the paid-up don't get posted, the unpaid do, and the pot is split among the message-writers. Read the rest
