# What Does the Free Will Theorem Actually Prove

@article{Goldstein2009WhatDT, title={What Does the Free Will Theorem Actually Prove}, author={Sheldon Goldstein and Daniel V. Tausk and Roderich Tumulka and Nino Zangh{\'i}}, journal={arXiv: Quantum Physics}, year={2009} }

Conway and Kochen have presented a "free will theorem" (Notices of the AMS 56, pgs. 226-232 (2009)) which they claim shows that "if indeed we humans have free will, then [so do] elementary particles." In a more precise fashion, they claim it shows that for certain quantum experiments in which the experimenters can choose between several options, no deterministic or stochastic model can account for the observed outcomes without violating a condition "MIN" motivated by relativistic symmetry. We…

Free Will in a Quantum World?

In this paper, I argue that Conway and Kochen’s Free Will Theorem (Conway and Kochen 2006, 2009) to the conclusion that quantum mechanics and relativity entail freedom for the particles, does not…

Systems of random variables and the Free Will Theorem

- Mathematics
- 2020

This work reformulate and generalize the Free Will Theorem theorem in terms of systems of random variables, and shows that the proof is based on two observations: some compound systems are contextual (non-local), and any deterministic system with spacelike separated components is non-signaling.

Are Humans the Only Free Agents in the Universe

In 2006, John Conway and Simon Kochen published their provocatively titled Free Will Theorem. The theorem, it is claimed, proves that if humans are truly free agents, then so too are elementary…

Constraints on Determinism: Bell Versus Conway–Kochen
