I'm not getting what you're going for here. If these agents actually change their definition of fairness based on other agents definitions then they are trivially exploitable. Are there two separate behaviors here, you want unexploitability in a single encounter, but you still want these agents to be able to adapt their definition of "fairness" based on the population as a whole?

I'm not sure that is trivial. What is trivial is that some kinds of willingness to change their definition of fairness makes them exploitable. However this doesn't hold for all kinds of willingness to change fairness definition. Some agents may change their definition of fairness in their favour for the purpose of exploiting agents vulnerable to this tactic but not willing to change their definition of fairness when it harms them. The only 'exploit' here is 'prevent them from exploiting me and force them to use their default definition of fair'.

Ah, that clears this up a bit. I think I just didn't notice when N' switched from representing an exploitive agent to an exploitable one. Either that, or I have a different association for exploitive agent than what EY intended. (namely, one which attempts to exploit)
