I had the idea last night, based on this post, in fact, to begin teaching my kids the prisoner's dilemma as a way to talk about threat and use of force: if neither kid fights, they both get ahead! if one fights, and the other doesn't, then the aggressor (hopefully) gets a comeuppance BUT the kid who got punched, well, still got punched; if they both fight, they'll probably both wind up getting injured, which does typically spare them additional consequences but is the least desirable of all the options because bleeding and bruises.

I mean it's not an exact map and I'm still working it out, but I'm definitely thinking about this.
