After all **some** people have read the book by Sylvia Nasar and 'ere that (quite good) book was published, the readers of the **Prisoner's Dilemma** by William Poundstone learned about John's most famous mathematical discovery. Although the book deals more with the originator of game theory, Johnny Von Neumann, than the other John, the book explains the concept of the **Nash Equilibrium**. The Nash Equilibrium is a strategy where all players will not regret selecting what they did. Sad to say, it's also been found out that the Nash Equilibrium is often not the strategy that real world people choose. (William, by the way, wrote a previous book **Big Secrets**, where he first revealed the location of the grave of Walt Disney.)

But there are cases where not only do people often **not** act rationally, but it's not always in their best interest to do so. For instance, think about when ...
