I think it’s the only difference between CDT and TDT: TDT gets a semi-correct causal graph, CDT doesn’t. (Only semi-correct because the way Eliezer deals with Platonic nodes, i.e. straightforward Bayesian updating, doesn’t seem likely to work in general. This is where UDT seems better than TDT.)
That’s the main difference between decision theories like CDT, TDT and UDT.
