I feel again as if I do not understand what Timeless Decision Theory or Updateless Decision Theory is (or what it's for; what it adds to ordinary decision theory). Can anyone help me? For example, by providing the simplest possible example of one of these "decision theories" in action?
Suppose we have an agent that cares about something extremely simple, like number of paperclips in the world. More paperclips is a better world. Can someone provide an example of how TDT or UDT would matter, or would make a difference, or would be applied, by an entity which made its decisions using that criterion?
TDT and UDT are intended to solve Newcomb's problem and the prisoner's dilemma and those are surely the simplest examples of their strengths. It is fairly widely believed that, say, causal decision theory two-boxes and defects, but I would rather say that CDT simply doesn't understand the statements of the problems. Either way, one-boxing and arranging mutual cooperation are improvements.
