      Definition of “rationalism” from the Eggplant book draft. If you identify as a rationalist, I’m curious whether you find this accurate, and if not, why not?pic.twitter.com/2cvo7478fj

      IME with CFAR rationality, "ultimate" is giving the wrong impression - it sounds too universal. I'd argue that CFAR endorses a criterion *schema* around "what you personally want", but it's intended for everyone to substitute x=(you personally), after which it's highly subjective

      To put it another way, in this view there's an ultimate *meta*-criterion for one's own personal criterion for optimality. Ideal rationality means conforming to a criterion drawn from that family of criteria. But you get to set all the free variables to whatever you want.

      Interesting… What is the ultimate meta-criterion?

      A raw attempt at scaffolding, then answer: You're a human. You're not an abstract mathematical agent, but if you were, you'd have a single goal and you'd maximize it to the best of your ability. You sometimes act like you have goals. Other times, you act inconsistently.

      Of course, any sequence of actions can be modeled as maximizing some latent goal: for example, "output those actions in that order". Nailed it! But... you, human, you have an intuition that you really want something (or somethings!) more than that. What is it, I wonder?

      Let's pretend you actually do have just one goal, X- could be whatever, up to you. To the extent your actions are not actually the ones that would maximize X, you're leaving value on the table. You could have more X if you acted differently. Instead, sometimes you act to reduce X

      Acting *more* rationally in this framework is to act in ways that more consistently bring you to maximize/optimize some X="the stuff you really want". You can fill in X. Economics at that level is the meta-criterion.

      Is there some ultimate, universal X? Heck no. That's up to *you*. Sure, some are more likely for a human to want. If you were to assert that "no, no really, the highest goal I have is to perform the actions I perform in the order I perform them" then I would be really skeptical.

      So, then, would you take my definition as accurate, with the variable bindings: Criterion = maximize whatever you want Method = take whatever action has the highest value of probability * desirability of outcome?

          Yes to criterion. Method... not quite? If you as a human were to run the algorithm "take whatever action you compute to have the highest value of probability * desirability" you're gonna have problems. CFAR's method is like ... introspect? write stuff down? remember to sleep?

          Why those methods? *because* when you use them, you tend to satisfy the criterion. But they're a grab bag of methods, not one weird trick, because you are a human, not AIXI (https://en.wikipedia.org/wiki/AIXI ). If you try to act like AIXI you'll have a bad time.
