Yeah 99% of the work is figuring out how a human, with a messy human brain, can approximate the normative model. What heuristics work well, in what contexts? When is following explicit rules useful vs. just training your intuition through experience? etc. Lots of diff. ideas here
Priors are an epistemological matter, not an ontological one. A utility function is ontological, I guess… but not at all what I have in mind. Rather: what is the right vocabulary for describing this sort of situation? Where “right” means not “ultimately correct,” but “helpful.”

I've been holding back from saying anything like the following, because it is indeed an obnoxious move, but I keep wondering what "helpful" grounds out to, for you, if anything - How do you know what's "helpful"? (And yes, it's epistemics again; feel free to throw ontology back)

I think all categories (outside math) are necessarily somewhat vague, and that this is not generally a problem. That includes “helpful.” There’s no general criteria. In particular domains, one can make cogent arguments about whether a particular thing is helpful or not.
