Let’s consider (2). Suppose someone was in the process of getting Dutch Booked like this. It would not go on ad infinitum. They would quickly learn better. Right? So even if this happened, I think it would not be a big deal.
So the argument is now not that that suboptimal issues don’t exist but that they aren’t a big deal? Are you aware that the primary reason that this involves small amounts of ice cream is for convenience of the example? There’s no reason these couldn’t happen with far more serious issues (such as what medicine to use).
I know. I thought it was strange that you said “ad infinitum” when it would not go on forever. And that you presented this as dire but made your example non-dire.
But OK. You say we must consider probabilities, or this will happen. Well, suppose that if I do something it will happen. I could notice that, criticize it, and thus avoid it.
How can I notice? I imagine you will say that involves probabilities. But in your ice cream example I don’t see the probabilities. It’s just preferences for different ice creams, and an explanation of how you get a loop.
And what I definitely don’t see is probabilities that various theories are true (as opposed to probabilities about events which are ok).

Yes, but the Bayesian avoids having this step. For any step you can construct a “criticism” that will duplicate what the Bayesian will do. This is connected to a number of issues, including the fact that what constitutes valid criticism in a Popperian framework is far from clear.

Ice cream is an analogy. It might not be a great one since it is connected to preferences (which sometimes gets confused with Bayesianism). The analogy isn’t a great one. It might make more sense to just go read Cox’s theorem and translate to yourself what the assumptions mean about an approach.

Anything which is not itself criticized.

Could you pick any real world example you like, where the probabilities needed to avoid dutch book aren’t obvious, and point them out? To help concretize the idea for me.

Well, I’m not sure, in that I’m not convinced that Dutch Booking really does occur much in real life other than in the obvious contexts. But there are a lot of contexts it does occur in. For example, a fair number of complicated stock maneuvers can be thought of essentially as attempts to dutch book other players in the stock market.

I didn’t say that (I’m not endoself).

OK, my bad. So many people. I lose track.

Koth already had an amusing response to that.
Someone here told me it does. Maybe you can go argue with him for me ;-)
I agree.
