The prisoner’s dilemma is a great example of game theory.  In figure 1 you can see the generalized form of the payout structure for 2 individuals (vertical and horizontal) either cooperating and telling the truth (C) or defecting and not confessing (D).  If you are interested in learning more about the prisoner’s dilemma, the wiki on the subject is a great place to start!  http://en.wikipedia.org/wiki/Prisoner’s_dilemma

The Survivor example is one of my favorites ever.  I doubt Richard had any idea exactly how accurate his decisions were on a purely statistical level.  This is a great way to show how naturally we all process this data.  A Good Guy To Know should realize how powerful this kind of thinking can be!  This chart was taken from the game theory textbook Games of Strategy (Dixit, Skeath, Reily Jr., 2009).
