Paper: Information Theory of Action: Reconstructing Quantum Dynamics from Inference over Action Space

What they're saying

The paper claims to derive quantum mechanics from information-theoretic principles.

The Critique

This is philosophical sleight of hand. You can't claim to have explained quantum mechanics when you've baked the formalism into your assumptions. The derivation assumes 'action additivity' and 'probability normalization' as primitive postulates, but these are essentially equivalent to the quantum mechanical principles they're trying to derive.

Why It Matters

If the derivation is circular, it's not a reconstruction of quantum mechanics from information theory but a reformulation. This matters for foundational physics programs seeking to derive quantum mechanics from more primitive principles.

What They Missed

The 'finite resolution scale' that makes action contributions indistinguishable is identified with ℏ empirically—but this is circular: ℏ already contains quantum mechanics.

The Big Question

Can quantum mechanics truly be derived from information-theoretic principles, or will any such derivation necessarily assume what it seeks to prove?
