a population of mostly TDT/UDT agents and few CDT agents (and nobody knows who the CDT agents are) and they’re randomly paired up to play one-shot PD, then the CDT agents do better. What does this imply?
My current hot take is that this is not a serious problem for TDT/UDT. It’s just a special case of the more general phenomenon that it’s game-theoretically great to be in a position where people think they are correlated/entangled with you when actually you know they aren’t. Analogous to how it’s game-theoretically great to be in a position where you know you can get away with cheating and everyone else thinks they can’t.
