"The probabilities are what they are, no matter what we want, no matter what we visualize, no matter what we meditate upon while imbibing inspirational substances. It doesn’t matter how much you want that electron to be spin up, it doesn’t matter how many good “vibes” you give the electron about being spin up, it always has exactly a 1/2 chance of being spin up, a 1/2 chance of being spin down."

Even if the evolution rule is deterministic, it's still epistemically/indexically nondeterministic from the perspective of the observer.

Quantum events in the brain would decohere almost immediately, leading to effectively nondeterministic behavior at any scale above the cellular. The philosophical determinism of wavefunction realism (which is the LW argument) is irrelevant to the actual behavior.
