The Parasite Dilemma
The Traveler's Dilemma has inspired me to create this Parasite Dilemma. I wonder if it's an innovation or if someone else has already invented it. If it's an innovation you saw it first here on SMP.
The Parasite Dilemma -------------------- You are part of a group of 100 people. Each person in the group writes down on a piece of paper their decision whether to be a Contributor to the Group or a Parasite on the Group. The Operator of the experiment will add $100 to the Group's Treasury for every Group Contributor. For every Parasite on the Group, $200 will be subtracted from the Group Treasury, which may go into debt. Each Contibutor gets 1 Share and each Parasite gets 2 Shares in the Treasury. The Treasury is then divided amongst the Contributors and Parasites according to their Shares in the Treasury. If the Treasury is positive each Parasite will recieve twice as much of the proceeds as each Contributor. On the other hand, if the Treasury is in Debt each Parasite must pay out twice as much as each Contributor to pay off the Debt. What is your decision? Do you decide to Contribute to the Group or be a Parasite? There is also a NonDebt version of the Dilemma where the Treasury cannot fall below zero. What is you decision in the NonDebt Version?

For cooperation, altruism, etc. to work in social animals there needs to be a way to detect cheats and Parasites, and to ostracise or eliminate them. But to clarify for posters in this thread, PTB is talking about a kind of multiplayer, but one-off, Prisoner's Dilemma, and I am talking about an iterated version of it. But I won't iterate my comments in case you get iteration irritation.

By removing the easy answer I think the Parasite Dilemma isolates a concept that has been elluding us. PairTheBoard

Re: The Parasite Dilemma
Without having given it much thought, and reserving my right to change my answer later, you can take me down to the Parasite City

If more than 1/3 of the participants decide to be parasites you will end up doing worse than the contributors. You will owe more money than they will. PairTheBoard

PairTheBoard [/ QUOTE ] Im well aware I just dont think, out of 100 random people, enough of them not contribute for this to be relavent Look at the percentage of the population that votes, to see evidence for the "what if everyone else did it?" syndrome
