Does QM allow "free will"? Some people argue that QM is complete because if there were deterministic hidden variables behind QM, then the determinism would not allow free will. However, such an argument for completeness of QM is completely meaningless for the following reason: If QM is complete, then fundamental laws of nature are purely probabilistic and physical events are fundamentally random. Fundamental randomness does NOT allow free will. For example, if there are 50:50 chances for two different behaviors of a human, then the human cannot decide to behave allways in the same way. Thus, everyone who believes in free will should reject completeness of QM!
