Quick dive into the concrete: I think that legalization of marijuana would be a good thing … but that evaluation is based on my current state of knowledge, including several places where my knowledge is ambiguous. By Baye’s Rule, I can’t possibly have a nonzero expectation for the change in my evaluation based on the discovery of new data.
Am I misunderstanding the situation you hypothesize?
You can have a nonzero expectation for the change in someone else’s evaluation, which is what I was talking about. The super-agent and the sub-agent have different beliefs.

I see—that is sensible.
