If probabilistic outcomes are the same as having a free will, then elementary particles also have free will. That doesn't fit the intuitive fuzzy definition of free will.
Some readers may object to our use of the
term “free will” to describe the indeterminism of
particle responses. Our provocative ascription of
free will to elementary particles is deliberate, since
our theorem asserts that if experimenters have a
certain freedom, then particles have exactly the
same kind of freedom. Indeed, it is natural to
suppose that this latter freedom is the ultimate
explanation of our own.
