• Red Chile, Green Chile
• Surprising dynamics of a very simple social
  system
• We often begin this study of this system with a
  game where students play the role the agents play
  in the computer model.
• Data is collected (secretly) about the
  distribution of red and green chile partisans,
  and plotted on a spreadsheet out of sight of the
  participants in the game.
• People are often poor at guessing the results of
  the game in terms of systems dynamics
• Question What happens when you try to be in the
  minority?

• Rules of the majority game
• Pick a chile color, with the distribution
  determined according to slider setting
• Move randomly
• After you have met five people, choose the
  chile favored by the majority of them
