You are under the annoyingly common misconception that choice between A and B means that whether A or B is chosen is indeterminate (i. e. either incoherent free will magic or identifying yourself more strongly with your randomness source than your fixed qualities). What it actually means is that whether A or B is chosen depends on your preferences and your decision making process.
All right; I stated that incorrectly. We can regard the actions of deterministic agents as "choices"; we do it all the time in game theory. What I was trying to get at is not the choice of A or B, but the choice to use TDT.
It sounds to me like TDT is not addressing the question, "How do I convince an agent to adopt TDT?" It assumes that you're designing agents, and you design them to implement TDT, so that they can get better results on PD when there are many of them.
But then it's not fundamentally different from designing agents wit...
