Iterated prisoners’ dilemma is used to model the breakdown of reputation. Roughly speaking, when the interaction count is high, there’s plenty of time to realize you’re playing against a defector and to punish them, so defectors don’t do very well—that’s a reputation system in action. But as the interaction count gets lower, defectors can “hit-and-run”, so they flourish, and the reputation system breaks down. The link goes into all of this in much more depth.
Dunbar just comes in as a (very) rough estimate for where the transition point occurs.
Fwiw, I keep bouncing off the Iterated Prisoner’s Dilemma app, because no one really gave it much context and the initial few rounds seemed very much like stuff I already knew. (this is more of a general message to people trying to share the app – I think if this was my first exposure to it I’d have bounced off again, and if people explained how long it took to play and roughly what they got out if I’d have played it sooner)
