Wdym?free will is a double-edged sword
The introduction of probabilities into mathematical models at the quantum scale is indeed a consequence of the inherent uncertainty and limitations in our ability to measure. Quantum mechanics relies on probabilities to describe the behavior of particles because, at that scale, traditional concepts of determinism break down. While there is no hard evidence suggesting that things are inherently random at the quantum level, the probabilistic nature of quantum mechanics has been extensively validated through experimental observations and predictive power. However, interpretations of this probabilistic behavior vary, with some interpretations suggesting underlying deterministic processes masked by our current understanding and measurement limitations.@DarkRange55 I strongly disagree with the "quantum mechanics" argument for free will. My understanding is that our scientific instruments aren't precise enough to accurately measure things at that scale, so we have to introduce probabilities into our mathematical models of subatomic particles to account for our own uncertainty. As far as I'm aware there's no hard evidence that things are actually random or probabilistic at a quantum level.
But, for the sake of argument, let's say there is true randomness at the quantum level. Randomness at a quantum level does not mean there's randomness at a macroscopic level. I can't remember the last time I was eating an apple and it randomly vanished from my hand and appeared half-way across the room as a mango. Can you? Most of our technology wouldn't work if things like this happened, and so quantum randomness, if it exists, does not affect things at the macroscopic level, like apples, mangos, and human brains.
But, for the sake of argument, let's get really crazy and say quantum randomness affects things at the macroscopic scale, that's still not an argument for free will, it's an argument for random will, and random will is not free.
At this point, we have to completely abandon reality and fabricate supernatural explanations to make free will work. It's not enough for consciousness to be an emergent property of our physical brains, we now have to make up a "soul" that drives our consciousness independently of our physical brains and the main mechanism it uses to accomplish this is "quantum randomness." Great. We did it. We found "free will." All it took was lying to ourselves and making up complete nonsense.
However, for the randomness, one example would be with quantum tunneling, that the probability of an object passing through a barrier, decreases in likeliness, as the scale increases, but is not equal to zero - Quantum mechanics theoretically works on every scale – it just becomes much much much much less likely for particle tunnel through a macroscopic barrier, but there is no dividing line.@DarkRange55 I strongly disagree with the "quantum mechanics" argument for free will.

I do not believe in the immortal soul personally. We do not know if consciousness is an emergent property or not yet. And as I said, in the beginning, I'm not sure if free will exists or not.@DarkRange55 I strongly disagree with the "quantum mechanics" argument for free will.

Also, the stochastic features of QM could leave, in principle, a "trace" at the macroscopic level.@DarkRange55 I strongly disagree with the "quantum mechanics" argument for free will.

In other words, in the classical limit the quantum non-commutative probabilities (states) become, in general, classical probabilities in the phase space (statistical states). There are quantum states that in the limit become points of the phase space (not surprisingly, this is the case for the squeezed coherent states of minimal uncertainty), but these are only special cases.Every possible classical phase-space probability distribution can be obtained from some suitable quantum configuration, in the classical limit.
