Dr. Bee Pushes Superdeterminism Again

I have defended Dr. Bee, as she often gives nice summaries of science outside her expertise. But not when she gets Physics in her own expertise wrong. She explains:
7:20 And then let me finally say some words about how superdeterminism 7:24 explains the quantum mechanical result. Superdeterminism is an unfortunate 7:29 term that John Bell used to describe what he thought was an implausible explanation. What 7:36 it really means is just that the probability of a measurement outcome depends on what you 7:41 measure. In the GHZ table this means that for example the result for the side of the second 7:48 coin in the third measurement can differ from the one in the first measurement, 7:53 because the measurements on the other coins are different. The result depends on the context. 7:59 The benefit of superdeterminism, and the reason why I am convinced it’s the correct explanation, 8:06 is that it is local and therefore compatible with Einstein’s theory. Superdeterminism has 8:13 no “spooky action at a distance.” Indeed, we know from Bell’s theorem that it’s 8:18 the *only way to make the results of quantum mechanics compatible with Einstein’s locality. 8:25 People don’t like this explanation because they think it’s constraining 8:29 their free will or something. But the way that I think about it is just that it’s 8:35 a consistency requirement. And yes I am working on a few more papers about this,
She is writing wrong papers. In quantum mechanics, the measurement outcome depends on what you measure. That has been accepted wisdom for a century. It is not superdeterminism, which nearly everyone rejects as not only implausible, but crazy.

Bell's theorem says that superdeterminism is the only way to make a local hidden variable theory compatible with known Physics. But again, mainstream physicists and textbooks have rejected hidden variable theories for a century.

Textbook quantum field theory is local, and compatible with relativity.

People do not like superdeterminism not just because it eliminates free will, but that it any possibility of doing a scientific experiment. It is part of The Existential Crisis Iceberg. If you accept it, there is no returning to rational thought.
