Of course if we just want some space of possible values, and where each value has an opinion of each value, then that’s just a continuous function from a product of the space with itself, which isn’t any problem.
Yeah, I just meant this simple thing that you can mathematically model as $$f : V \times V \to \mathbb R$$. I suppose it makes sense to consider special cases of this that would have better mathematical properties. But I don’t have high-confidence intuitions on which special cases are the right ones to consider.
I mostly meant this as a tool that would allow people with different opinions to move their disagreements from “your model doesn’t make sense” to “both of our models make sense in theory; the disagreement is an empirical one”. (E.g., the value-drift situation from Figure 6 is definitely possible, but that doesn’t necessarily mean that this is what is happening to us.)
