I don’t think it’s useful to think about constructing priors in the abstract. If you think about concrete examples, you see lots of cases where a reasonable prior is easy to find (eg coin-tossing, and the typical breast-cancer diagnostic test example). That must leave some concrete examples where good priors are hard to find. What are they?
