This question already has an answer here:
I think that QM does not favor free will, any more than Classical Mechanics does, and here is my reasoning:
QM predicts odds, but that doesn't mean we are free, right? To be free, we will have to change the odds in our favor, so to speak. Maybe I don't understand probability well, but it seems to me that fixed odds still mean no free will.
The laws of QM have been shown (somewhat) to give the same results as Classical Mechanics at macroscopic scales. So all the previous arguments about whether there is free will or not can continue to be valid (I suppose).
So, what is wrong with this reasoning?
