As far as I understand the main thing that is missing is a solid theory of logical counterfactuals.The main question is: In the counter-factual scenario in which TDT recommends action X to agent A , what does would another agent B do?How does the thought process of A correlate with the thought process of B?
There are some games mentioned in the FDT and TDT paper which clearly involve multiple TDT agents.The FDT paper mentions that TDTs "form successful voting coalitions in elections",and the TDT paper mentions that TDTs cooperate in Prisoner's Dilemma.In th... (read more)
Yeah, my argument here is not contradicting the paper,because the case of a TDT agent blackmailing a TDT agent is not discussed.I just wanted to know whether the resistance against blackmail extortion still applies in this case,because I think it doesn't.
But in some situations the logic can absolutely be applied to "normal causal blackmail".If a CDT agent sends a completely normal blackmail to a TDT agent,and if the CDT agent is capable of perfectly predicting the TDT agent,then that is precisely the situation in which resisting the extortion makes sense.I...

Would a TDT agent also just always send all possible blackmail to other agents, independently of whether they think it gets accepted or not, and just live with the consequences?They might want to do that, because if they did, then they would encounter less universes in which their blackmails get rejected, because it's known that rejecting their blackmail doesn't disincentivize them from sending it.Like, I don't believe TDT actually recommends that, but it's the same logic that justifies rejecting all blackmail.
In any case, the decision theory of the blackm... (read more)
