I say that free will is not a scientific issue.
I have criticized Free will in the multiverse.
On the physics side, the Free will theorem claims that human free will is linked to quantum indeterminism.
The theorem states that, given the axioms, if the two experimenters in question are free to make choices about what measurements to take, then the results of the measurements cannot be determined by anything previous to the experiments.I don't see how this theorem says anything about free will. The theorem has three plausible sounding axioms, but it also assumes a deterministic model for producing photon pairs. According to the model, the photon seem to have some random aspects that observers can see if they are allowed to make their own random choices. So the theorem shows that the models are really indeterministic.
This is all just a fancy way of saying that there are quantum experiments that look random. This doesn't mean much as coin tosses look random also, but could be deterministic if you knew more about the coin.
