Superdeterminism makes Science Impossible

Superdeterminism has very few adherents, like Sabine Hossenfelder. I would ignore it completely, as too nutty to discuss, except that she has become one of the most prominent expositors of Physics.

Here is a new paper, discussing one of the main problems:

This is one of the longest-standing objections to (naïve) superdeterminist theories, often referred to as the Tobacco Company Syndrome (Hossenfelder and Palmer, 2020). Fundamentally, it is an epistemological concern. In Maudlin’s formulation (2019), the objection draws an analogy with a tobacco industry apologist who first invokes a common cause to deny that smoking produces cancer, and then, when confronted with randomised animal trials, insists that the randomisation procedure itself was somehow biased in favour of placing cancer-prone subjects in the experimental group, a move Maudlin regards as wholly unscientific. It is not difficult to see the risks to scientific practice if this objection were to remain unresolved within superdeterminism. Such a denial of Statistical Independence would imply, for instance, the impossibility of discussing isolated systems or experimental random errors. Moreover, it would pose a significant risk to the empirical coherence of the theory, as defined by Barrett (1996).

That is right, if you believe in superdeterminism then it is impossible to do an experiment to prove that tobacco smoking causes cancer. It is also impossible to do any other experiment, or reach any scientific conclusions.

Many-worlds theory has similar problems. It makes all scientific work impossible.
