I'll never throw a 2

Dr. Tim Lautzenheiser is a former band director that currently travels the country giving motivational lectures and workshops on education. Check out his bio at www.attitudeconcepts.com/timsbio.php . He is in Louisville this weekend for the Bands of America competition (marching bands), and gave a presentation at U of L this afternoon. Besides being simply amazing, the presentation was terrifically entertaining.

My favourite part of the presentation was a discussion of trust and interest. He presented a game that is basically a derivative of the philosopher’s “inmate dilemma.”

Based on ‘paper, rock, scissors,’ two players decide on the third ‘beat’ whether to throw a 1 or a 2. If A throws 1 and B throws 2, then A loses 3 points and B gains 5. If A throws 2 and B throws 1 the opposite occurs. If both A and B throw 2’s, then both players loose 8 points. If both A and B throw 1’s, then both players gain 1 point.

Since the net gain of the possibilities of throwing a 2 are –3, it never makes sense to throw it. However, this requires that the opponents trust that one is not attempting to deceive the other. The only way to win in this game is by accepting the smallest gain available.

Applications are obvious.
