I am such a geek - I think it's fun to see applied mathematics in the news. From James Galbraith in the HuffPo, on the subject of "A Few Very Simple Thoughts on Plamegate":
4. If you were Dick Cheney, how would you feel about this? You don't know, you can't know, how Libby's feeling right now; that information is locked up in Libby's head. But you do know that he doesn't know, for sure, whether he can expect help from you. And you can't tell him, can you? At this point, Libby is beyond your control. If you have something to hide that he knows, you have to take it on faith that he won't divulge it. That being so, exactly how do you plan to handle your testimony at Libby's trial? This is, well, the prisoner's dilemma. It's set it up so that if Libby delivers Cheney, he will be better off than if he doesn't. And Cheney knows this now.Brush up on your game theory here.
