In the most important theory in physics, Quantum Mechanics, no such assumption is made, and despite a century of trying no experiment has ever been performed that even hinted such a deterministic assumption should be added in.

What?

Everett = SWE. The wave evolves deterministically.

It was only when confronted to the explosion of realities that QM entails that physicists admitted a (unintelligible) wave reduction which introduced indeterminism in the picture, and Einstein never bought it at the start.

I bought it, but that was an error of youth, not helped by the textbook which dare to add the collapse as an axiom.

Everett is just a coming back to the old but venerable tenant of physics: 3p determinacy. Everett indeterminacy is typically 1p indeterminacies.

It is not that QM assumes determinacy, it is that Everett shows we don't need to assume indeterminacy (which for a logician is a much more stronger assumption, even insanity for Einstein).

Somehow Everett shows that Einstein was constantly right on QM. His critics was on QM+collapse, if you look close.
