I thought "Schelling point" was used by the decision theory workshop folk, I may be wrong.

Relevance? (That people in group Y use a word doesn't obviously clarify why you used it.)

I mistakenly thought that Will Sawin was in said group and was thus expressing confusion that he wasn't already familiar with its broader not-quite-game-theoretic usage, or at least what I perceived to be a broader usage. Our interaction is a lot more easily interpreted in that light.

(I didn't understand what you meant either when I wrote that comment, now I see the intuition, but not a more technical referent.)

And if you meant that you don't see a more technical referent for my use of Schelling point then there almost certainly isn't one, and thus it could be claimed that I was sneaking in technical connotations with my naive intuitions. Honestly I thought I was referring to a standard term or at least concept, though.

The term is standard, it was unclear how it applies, the intuition I referred to is about how it applies.

Can you explain that intuition to me or point me to a place where it is explained or something?

Or, alternately, tell me that the intuition is not important?

Two agents in a PD can find a reason to cooperate in proving (deciding) that their decision algorithms are equivalent to some third algorithm that is the same for both agents (in which case they can see that their decision is the same, and so (C,C) is better than (D,D)). This common algorithm could be seen as a kind of focal point that both agents want to arrive at.

I don't think it matters much, but the specific agents I had in mind were perhaps two subagents/subalgorithms (contingent instantiations? non-Platonic instantiations?) both "derived" (logically/acausally) from some class of variably probable unknown-to-them but less-contingent creator agents/algorithms (and the subagents have a decision theory that 'cares' about creator/creation symmetry or summat, e.g., causally speaking, there should be no arbitrary discontinuous decision policy timestamping). There may be multiple possible focal points and it may be tricky to correctly treat the logical uncertainty.

All of that to imply that the focus shouldn't be determining some focal point for the universe, if that means anything, but focal points in algorithmspace, which is probably way more important.

Ah, I see.

(I, on the other hand, don't.)

The intuition that "Schelling points" are an at all reasonable or non-bastardized way of thinking about this, or the intuition behind the "this" I just mentioned? If the latter, I did preface it with "naively", and I fully disclaim that I do not have a grasp of the technical aspects, just aesthetics which are hard to justify or falsify, and the only information I pass on that might be of practical utility to folk like you or Sawin will be ideas haphazardly stolen from others and subsequently half-garbled. If you weren't looking closely, you wouldn't see anything, and you have little reason to look at all. Unfortunately there is no way for me to disclaim that generally.
