It also sounds like you mean that, in math, we can work out that each model prediction is "ackshually" a probability, like the mean of a normal distribution, or whatever. What my question boils down to is this: "all other things being equal, is it better to believe an assertion that is provable but not testable, or an assertion that is testable but not provable?" Why?
