Rex, I have three questions, which I couldn't find answers to on the website, though I may have just missed the correct links.

  1. Are the students more likely to reach agreement under lots of pressure, or if someone comes in and relieves the pressure?
  2. Are they more likely to come to agreement if there's no fighting, or if they've bloodied each other a little?
  3. What can we learn from these experiments? (Feel free to point me to someone's thesis. There's no reason you should do all the work.)
