Here are more examples that I do believe that this analog contains an important grain of truth...

In most textbooks on special relativity or electrodynamics, it is mentioned sooner or later that the Lorentz transformations are...

Let me try to rephrase this question for @Morbert. The "branches" being talked about here are branches of the wave function. The...

But it can't be just that, if your other criticism is valid. If it's just statistical conditioning, then there is no actual collapse...

David Albert writes: "It gives us (in particular) probabilities that the configuration of the world will be this or that at any time t...

For a subsystem constantly interacting with its environment, the stochastic dynamics will be divisible. They can be defined in terms of...

Yes, this is the meaning of that product symbol with two subscripts.

Let me verify: I have to admit that the bold parts (bold by me) suggest that Barandes distinguishes between the t' at which the...

But Barandes didn't even clarify this much. And it can make sense not to clarify, because there could be spurious division events. I...

Thanks, now I see what you mean. And based on Barandes' answer (he doesn't want to make any "arbitrary" clarifications beyond what is...

I think the comparison with Everett is pertinent. In Everett's interpretation, if the wavefunction splits into two decoherent branches...

See this timestamp, where he distinguishes the dynamical conditional (transition) probabilities from the epistemic standalone probabilities.

At the timestamp, Barandes remarks on the distinction between standalone probabilities and transition probabilities, the latter of which...

I get your point, it does raise problems! Also in the normal paradigm, we shouldnt confuse them. But here we try to probe deeper I...

That is beside the point. After one has setup a model for a specific physical situation, the roles are fixed. Procrastinating over the...
