Oh this is quite simple really.

First I would build a simple room that had no exits.  Inside of that room I would place 3 pizzas, a feral cat, a bucket, and 1 die.

I would then select 10 random players from the league and place them in the room where they would be forced to live out the rest of their lives, aside from the final survivor.  How would they determine who gets to eat the pizza?  Would they choose to eat the cat eventually or would the cat find a way to eat one of them?  What creative uses would they find for the bucket?  What about the die?  Would they allow for chance to take a role in the survival of one another, or would the die end up being used merely for entertainment of some sort?

By running this simulator over and over, and by selecting different personality types and team mates, I could get a very good idea of how human beings react to one another when placed into very difficult circumstances.  I would like find out how many of them would rather starve than eat pineapple on pizza.
