I... am not sure that I understand what you mean ?

That after shuffling you know less about the stack of cards (that used to be at least partially revealed) is a fact that our model must follow or fail at being relevant.

It's been hard to find out more information about this, but I did find some :

https://www.preposterousuniverse.com/blog/2015/08/11/the-bay...

Same thing : "And the Bayesian Second Law (BSL) tells us that this lack of knowledge — the amount we would learn on average by being told the exact state of the system, given that we were using the un-updated distribution — is always larger at the end of the experiment than at the beginning (up to corrections because the system may be emitting heat)."

Though I also did find another interesting thing :

http://jakevdp.github.io/blog/2014/03/11/frequentism-and-bay...

"in a strict frequentist view, it is meaningless to talk about the probability of the true flux of the star: the true flux is (by definition) a single fixed value, and to talk about a frequency distribution for a fixed value is nonsense"

But that's pretty much the case in statistical physics ! A macrostate is actually NOT a state (=microstate), but a probability distribution !

"For Bayesians, probabilities are fundamentally related to our own knowledge about an event. This means, for example, that in a Bayesian view, we can meaningfully talk about the probability that the true flux of a star lies in a given range."

So looks like statistical physics are already at least part-way between Frequentist and Bayesian ??

Also, this one sounds potentially interesting, but sadly, paywalled...
