About a year ago I posted a link to a YouTube video of the Golden Balls “Split or Steal” game, hailing it as a godsend for teachers of game theory and the Prisoners’ Dilemma. That video has made its way around the web in the year since and I sat down to prepare my introductory game theory lecture yesterday looking for something new.
Well, it turns out that now there are many, many new videos of Split or Steal on YouTube and you can spend hours watching these. Here is my favorite and the one I used in class today.
I also heard from Seamus Coffey who has analyzed the data from Split or Steal games and finds:
- Women are more cooperative than men, non-whites more than whites, the old more cooperative than the young.
- There is more cooperation between opposite-sex players than when the players are of the same sex.
- The young don’t cooperate with the old, and the old discriminate even more against the young.
- Blonde women cooperate a lot. Men cooperate less with blondes than with brunettes.
Here is a link to a paper by John List who looks at similar patterns in the game Friend or Foe.

I’d be terrible at this kind of game because I’d always choose split.
If the other person chooses split, I’m happy with half. If the other person chooses steal, it doesn’t matter what I choose, because I go home with nothing (whether or not I chose steal myself).
I wouldn’t be happy choosing steal if the other person chose split. It would literally haunt me.
Similarly, it wouldn’t bother me that much if the other person got the money and I didn’t. I figure his or her karma will balance that account in the long run anyway…

How about this strategy: “I promise I will choose STEAL but I’ll split it with you after the game.” Insist that you’re choosing STEAL no matter what they say. If your opponent believes you’ll really do that — and why wouldn’t they? — then their choice is to let you have the money or to let the show have it. They might as well let you have it in case your offer to split it afterwards is genuine.
Then for a twist, choose SPLIT, contrary to your promise. If they were outraged by your strategy and decided to STEAL then they might feel bad enough that you actually chose SPLIT that *they’ll* split the winnings with you afterwards.
