The Prisoner's Dilemma
You and your accomplice have been arrested for vandalism (you were stealing bricks from the wall of the Second National Bank).
The prosecutor knows you have already robbed the First National Bank, but lacks evidence to convict, so he locks you in sepa rate cells and offers you the following deal if you confess to robbing the First National Bank. (If neither of you confess, you will get the maximum sentence for vandalism, two years.)

Hobbes: If you confess the Godfather will see to it that the Mob rubs you out.

Gauthier: If you confess, nobody who finds out about it will ever rob a bank with you again. If fact, if you even look like the sort of person who would confess, you'll have trouble finding accomplices.
