I'm going to steal this for the ethics class I teach. Heh heh heh.
Of course, I'm still trying to develop a grading curve based on game theory and economics. Given there are only enough points available for 10% of you to get A's, most of you will get B's, and some of you will get C's. OR all of you can work together to get B+'s.
This probably wouldn't work. BUT I think it has possibilities ... Any ideas?
