Welcome to my web site about ethics decision theory, ethics game theory, ethics simulation, ethical dilemmas, and evolutionary ethics. With you, I would like to explore how ethical rules can be used to make decisions about our encounters with other people, and the consequences of those decisions. I present a brief summary of the field, the unique niches that I am exploring, and the results of some of my simulations.

There are three threads to this site, with each thread assuming that you are minimally acquainted with the previous thread:

1) The Prisoner's Dilemma. This is the standard 4-outcome model on which almost all current ethical game theory is based. 2 players have but 2 choices each in playing this game.

2) My research simulating individual decisions. Players may have anywhere from 2 to 4 choices per encounter. The number of possible outcomes is far greater, and we can statistically examine non-linear effects.

3) My research involving group membership. Players are now members of groups, and the structures of these groups influence the choices they make.
