Doesn't the choice of measurement prove free will

Click For Summary
SUMMARY

The forum discussion centers on the Free Will Theorem proposed by Conway and Kochen, which asserts that if two experimenters can freely choose their measurements, the outcomes cannot be predetermined. The theorem relies on three axioms: Fin, Spin, and Twin, with later modifications introducing the Min axiom to strengthen the argument. The discussion highlights the implications of the theorem on the concept of free will, suggesting that the choices made by observers in quantum experiments create reality. Participants debate the appropriateness of the term "free will" in this context, emphasizing its scientific rather than metaphysical significance.

PREREQUISITES
  • Understanding of quantum mechanics principles, particularly quantum entanglement.
  • Familiarity with the Free Will Theorem and its axioms: Fin, Spin, Twin, and Min.
  • Knowledge of experimental physics and measurement theory.
  • Basic comprehension of philosophical debates surrounding determinism and free will.
NEXT STEPS
  • Read Conway and Kochen's original paper on the Free Will Theorem.
  • Explore the implications of quantum entanglement on measurement choices in physics.
  • Investigate the Strong Free Will Theorem and its modifications to the original theorem.
  • Study the philosophical implications of free will versus determinism in scientific discourse.
USEFUL FOR

Physicists, philosophers, and anyone interested in the intersection of quantum mechanics and the concept of free will, particularly those exploring the implications of measurement choices in experimental settings.

That's their opinion. They haven't proved it. "Discarding" determinism as a "serious view" is an opinion, not a proof.

bhobba already said this mechanism is too complex for us to know. That's like saying U.F.O.'s are Alien spacecraft but it's too complex for us to know.

Once again: so all of chaos theory isn't science? It's no different from saying UFOs are alien spacecraft ?

hi, this is slightly off topic, but can someone clarify wat free will is?

obviously determinism means no free will, but non determinism doesn't imply free will. u might then say free will is behaviour that's not deterministic nor conforming to the calculated probability distributions of the system (a human in this case), but that still doesn't capture the meaning of free will. I am not sure free will makes any sense...

This paper by Scott Aaronson is a good starting point.

They say determinism can't be disproved therefore it's logically possible

To me, "refute" and "disprove" mean the same thing, so I don't know how they refuted determinism without disproving it.

Again, you're debating semantics just like you didn't like the term free will. I try to stay away from semantic debates and stick to the merits but here we go.

Conway is smart to say disproved because to disprove something is to show that it's false. You can refute an argument without showing that it's false. They have crippled determinism and made it essentially hard to accept while acknowledging it's still logically possible because the free will theorem doesn't disprove determinism.

Here's a recent article on the strong cosmic censorship conjecture.

Mathematicians Disprove Conjecture Made to Save Black Holes

Nearly 40 years after it was proposed, mathematicians have settled one of the most profound questions in the study of general relativity. In a paper posted online last fall, mathematicians Mihalis Dafermos and Jonathan Luk have proven that the strong cosmic censorship conjecture, which concerns the strange inner workings of black holes, is false.

Again, there's a difference between showing something is false Mathematically or through observed evidence and refuting something in a debate.

I don't see how, any more than @stevendaryl does.

No, there's a difference between actually refuting something--proving it false--and just stating your opinion that you think it's false.
