I think we are missing some context - and that is very important to show if the students could communicate/collaborate (such as a homework question) or a test question. > I would say at best you have a 50/50 chance of a total stranger choosing the option that is better for the common good. It depends on factors such as the student's current grade. I would argue you are more likely to choose 6 if you have a lower grade. > If it were the general public at large I would estimate at least 60% would choose the more personally beneficial option. Here is an related experiment. Choose N random people, and offer 2 choices: $50 or $200 and run the same experiment. Here is an interesting question - are people less "greedy" if the prizes/points have a greater span? Such as instead of 2 points and 6 what about 2 points and 20 points. I think the experiment is interesting any way you think about it.
