(This post assumes that the reader is fairly familiar with the decision theory of Newcomb-like problems. Schwarz makes many of the same points in his post “On Functional Decision Theory” (though I disagree with him on other things, such as whether to one-box or two-box in Newcomb’s problem). (ETA: Also see Bales (2018) (thanks to Sylvester Kollin for pointing out this reference).) Similar points have also been made many times about the concept of updatelessness in particular, e.g., see Section 7.3.3 of Arif Ahmed’s book “Evidence, Decision and Causality”, my post on updatelessness from a long time ago, or Sylvester Kollin’s “Understanding updatelessness in the context of EDT and CDT”. Preston Greene, on the other hand, argues explicitly for a view opposite of the one in this post in his paper “Success-First Decision Theories”.) I sometimes read the claim that one decision theory “outperforms” some other decision theory (in general or in a particular problem). For example, Yudkowsky and
