Norwegian experimental economists ran some social trust experiments on a sample of prisoners. In prison.
You'd think the first thing they'd do would be to try the Prisoner's Dilemma, right?
Alas, they run a dictator game and some variants on a trust game.
Is there no poetry left in the world?

Oh, they found that prisoners weren't much different from non-prisoners. But what a let-down. I'd have wanted to see two treatments on the Prisoner's Dilemma game. One with neutral framing, the other with the complete "Two prisoners, separated..." framing.
