Say, you are trying to figure out what the mass on an electron is. As you develop your experimental techniques, there will be better or worse approximate answers along the way. It makes sense to characterize the approximations to the mass you seek to measure as more or less accurate, and characterize someone else's wild guesses about this value as correct or not correct at all.

On the other hand, it doesn't make sense so similarly characterize the actual mass of an electron. The actual mass of an electron can't be correct or incorrect, can't be more or less... (Read more)(Click to expand thread. ⌘F to Expand All)Cmd/Ctrl F to expand all comments on this post

I follow you up until you conclude that priors cannot be correct or incorrect. An agent with more accurate priors will converge toward the actual answer more quickly - I'll grant that's not a binary distinction, but it's a useful one.
