Nate says: “The main datapoint that Rob left out: one reason we don’t call it UDT (or cite Wei Dai much) is that Wei Dai doesn’t endorse FDT’s focus on causal-graph-style counterpossible reasoning; IIRC he’s holding out for an approach to counterpossible reasoning that falls out of evidential-style conditioning on a logically uncertain distribution. (FWIW I tried to make the formalization we chose in the paper general enough to technically include that possibility, though Wei and I disagree here and that’s definitely not where the paper put its emphasis. I don’t want to put words in Wei Dai’s mouth, but IIRC, this is also a reason Wei Dai declined to be listed as a co-author.)”
