It's a three-value range voting (-1, 0, 1), right? Or am I supposed to choose only one? (I've downvoted three and upvoted two plus the karma sink.)
Yes, with this many options I think three-range voting is better than approval (0, 1) voting. We don't want to settle on one that 2/3 of people love and 1/3 of people hate, rather than one that 1/2 of people love and 1/2 of people are indifferent toward.
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!
