What is Superdeterminism? How Is it a Hidden Variable Theory?

This video explains what superdeterminism is and why it is a kind of hidden variable theory like Bohmian mechanics. But it can have local hidden variables and still violate Bell's inequality...because there is no measurement independence, or statistical independence.

This leads to superluminal communication. We've done tests with the polarization of light from stars 600LY distant. So you have to either change the polarization of the light on its way, or assume that everything is already figured out before anyone even thinks they're going to make the measurement.

I'm not sure how you get local hidden variables even with measurement correlation if the measurement device is not local to the source of the thing being measured.

I think i get it. I just gotta watch it two more times lol

Super determinism may imply that the observer and the measuring equipment and the measured objects are in some way in a quantum entangled matrix, possibly in a state of superposition by quantum tunneling.

I consider myself smart, but I watched this shit and had no fucking idea what they said.

"Measurement independence" is inconsistent with the philosophy of Kant. Superdeterminism is consistent with Kant's philosophy, which posits the "filter" of the categories and judgements of the human mind as governing the correlation of experience by "their" rules. In other words the "rules of correlation", such as causation, are not found in Nature but are found in the human mind (brain?) making the correlation of the contents of consciousness.
Ostensibly, therefore, forces and statistical outcomes do not exist independently of mind. The resulting conclusion, therefore must be that Nature is not independent.
According to Kant and superdeterminism there "may" be an independent "world", but, unfortunately, it can never be experienced, much less measured. What is experienced and measured is determined by mind: categories and judgements.
What then is experience? Does observation confirm theory, as is currently accepted by science; or does theory precede observation? Is quantum mechanics the forerunner to a new type of observation, a new consciousness? A new category or judgement? Or is all this just a symptom of delusion?
What is a delusion? A false observation (a trick of light) or a false assumption (a trick of intuition)? An illusion is when a trick of light gives one a false impression. As water in the desert. A delusion is when a false assumption(intuition) gives one a false expectation. As when the Michelson-Morley experiment was contrived to find the "aether"s direction.

Superdeterminism seems to imply you can't actually know what these "measurement dependent" correlations are unless you traced out the whole universe from the initial conditions with certain restrictions applied up until your actual experiment. In practice that is not possible, so in practice you have to just assume that the correlations are already there without a clear reason, that the particles you are going to measure just already "know" how to be correlated with your measurement device, which seems to be the same, at least mathematically, as nonlocality, even if it's philosophically interpreted to be different. I am not a physicist so I would wonder how physicists actually deal with this problem.

[KaliFissure]

It used to be called physics.
Materialism.
And then kids who read too much science fiction, and not enough science fact, invented multiverses and all the other imaginary aspects, which let to string theory which contributed only theory.

The universe is a physical thing.
You can tell when someone hits you with a car.
