  Yeah, this is not the Prisoner's Dilemma! The way they described it the table looks like this: Player 1, Player 2 C D ____ ____ C|1, 1|0, 1| D|1, 0|0, 0| In this case, both cooperate and defect are Nash equilibrium strategies, which is NOT the case for a Prisoner's Dilemma. In order for this to be the Prisoner's Dilemma, only defect must be in NE, see: http://en.wikipedia.org/wiki/Prisoner%27s_dilemma http://en.wikipedia.org/wiki/Prisoner%27s_dilemma

  The actual payoff matrix the experimenters used is here: http://www.plosone.org/article/slideshow.action?uri=info:doi/10.1371/journal.pone.0008483&imageURI=info:doi/10.1371/journal.pone.0008483.t001 http://www.plosone.org/article/slideshow.action?uri=info:doi... It does follow the rules of prisoner's dilemma, as far as I can tell.

  It is, but if both remain silent they get a smaller penalty than if both rat on each other.
