And the name UDT is just STUPID!
I hope you don't blame me too much for that, because it was Eliezer who gave it that name, and I was only complicit to the extent that I didn't object.
It only makes sense by redefining 'update'.
I think "updateless" was meant to refer to the fact that UDT doesn't do explicit Bayesian updating, which doesn't seem unreasonable to me...
(BTW I remember you once said you also didn't like the language I used to describe UDT, but didn't say why when I asked. I'm still curious about that.)

Not at all, and your work on the theory was excellent. I just hope that by the time the descendent decision theories evolve to a stable state that they have picked up a new moniker. The reflexive term sounds much more significant!

I think I would put less emphasis on subtracting updates and more on just which kind of information should be used. After all, not doing updates isn't the importa...
In my recent post, I outlined 5 conditions that I'd like a decision theory to pass; TDT, UDT and ADT pass them, while CDT and EDT don't. I called decision theories that passed those conditions "advanced decision theories", but that's probably not an optimal name. Can I ask you to brainstorm some other suggestions for me? (I may be writing a follow-up soon.)
As usual, it's best to brainstorm on your own before reading any of the comments. You can write down your ideas, then check if any have already been suggested, then comment with the new ones.
Thanks!
