Worth noting that this was written before Eliezer's "Toolbox-thinking and Law-thinking"; several LW commenters seem to feel that that the T-T & L-T post addresses the criticisms in this post (based on the comments at https://www.lesswrong.com/posts/gsQjde3qeZw36arYE/nostalgebraist-bayes-a-kinda-sorta-masterpost … ).

I disagree that this answers my criticisms. In particular, my section 7 argues that it's practically unfeasible to even write down most belief/decision problems in the form that the Bayesian laws require, so "were the laws followed" is generally not even *well-defined*.

To be a bit more precise, the framework with a complete hypothesis space is a bad model for the problems of interest, where the inability to work in such a space is part of the problem statement.

It's sort of like quoting an optimality result given access to some oracle, when talking about a problem without access to that oracle. If the preconditions of a theorem are not met in a given decision problem, "meet those preconditions" cannot be part of a strategy for it.

And also this. In conclusion,
@nostalgebraist’s write-up is excellent, and afaict the LW commenters have missed his point.pic.twitter.com/fTZmD4Sg0f

The only sense I can make of EY’s post is that it’s a reiteration of the Dutch Book argument: “yeah, whatever, but if you play a fair betting game using some other math, you’ll lose.” Which is true. Fortunately, the Count of Flanders. Unfortunately, nihilistic depression.pic.twitter.com/RNXMSbeHrZ

I wish you guys posted these comments at the LW thread not Twitter, so that the people disagreeing with you could answer and I could follow the conversation. :-)

I care about you. I don’t care about LW :)
