I see that you didn’t learn anything about the pre-split world, but I don’t see why that matters. Again, the epistemic rule that you can only learn from evidence that is causally related to the thing it is evidence of....doesn’t obviously apply to action. Learning has a world->mind arrow, action has a mind->world arrow.
The same thing is true about Eliezer post “What is evidence?”: namely, for any organism or system to use beliefs to maintain homeostasis, to survive or to steer reality at all requires mutual information between the organism and its environment.
Again, action does not destroy mutual information. If an indetrministic event occurs, you gain at least subjective infuriation about it. If the event happens to be your own undetermined decision...the same applies. If your decision was determined, no objective information is gained or lost. If your decision was predictable to yourself, no sujective information is gained or lost.
