Well, you understood it at the time I made it. After reading Eliezer_Yudkowsky’s deeper exposition of TDT with better understanding of Pearl causality, here’s what I think:
Psy_Kosh is right that in any practical situation, you have to be aware of post-decision interference by your innards. However, I think EY’s TDT causal network for the problem, as shown in AnnaSalamon’s post, is a fair representation of Newcomb’s problem as given. There, you can assume that there’s no interference between you and your box choice because the problem definition allows it.
And with that interpretation, the TDT algorithm is quite brilliant.
Sorry for extreme delay in getting around to replying. Anyways, yeah, I agree that TDT is nice and solves various things. I don’t want to completely toss it out. My point was simply “I think it’s very very important that we modify the original form of it to be able to deal with this issue. Here’s what I think would be one way of doing so that fits with the same sort of principle that that TDT is based on.”
