Decision theory


UDT one-boxes on Newcomb’s problem and pays the $100 in the counterfactual mugging problem.

6.c.  What kind of a CSA are you?  What are you really asking, when you ask what you “should” do in Newcomb’s problem?  What algorithm do you actually run, and want to run, there?


After all, Joe is a deterministic physical system; his current state (together with the state of his future self's past light-cone) fully determines what Joe's future action will be.  There is no Physically Irreducible Moment of Choice, where this same Joe, with his own exact actual past, "can" go one way or the other.
