Overview

Sabine Hossenfelder explains superdeterminism as an interpretation of quantum mechanics, addressing common objections and misconceptions, including the worry that it kills free will or science. She ties it to Bell's theorem and hidden variables.

On Hacker News

HN commenters point to it as a clear explanation of Bell's theorem and superdeterminism, though some criticize it as knocking down strawmen.

Randomly found a link to this video on super determinism from his blog and found it super interesting. 100% agree, what is 'free will' anyways? A concept with no scientific definition. Why is it even used to explain anything in quantum mechanics? [VIDEO]

Wow. I actually just saw [a video from Sabine Hossenfelder]( [VIDEO] ) about exactly this. Long story short, we don't know if quantum nonlocality is real. Bell's Theoreom doesn't prove nonlocality. It proves that locality is impossible with statistical independence, that is, the measurement itself affects the quantum system. We can preserve locality if we also accept superdeterminism, which Sabine succinctly puts as, "what the quantum particle does depends on what measurement will take place." We can accept nonlocality and statistical independence or locality and dependence. The former is taken for granted by Bell and many (most?) physicists today but only because the latter "feels" more spooky to a quantum physicist. The video does the subject justice much better than I can, but the point is that it's not cut and dry!

Some say that it has not been fully proved there are no hidden variables. [VIDEO] (Sabine Hossenfelder on Superdeterminism)
