Just needed a place to put this:
On Free Will and QM
14 July 2018
The question of free will in the face of deterministic laws of physics sometimes brings up quantum mechanics and the so-called uncertainty principle as a away to escape the strictures of a mechanistic theory. I think such an appeal is not necessary though. In fact, an effective free will can be achieved through information hiding and the limits of computation. First, to say a system, A, has free will means that, at any point in time, there is no observer which can simulate A faster than A can evolve in real time. Note that A can be a classically deterministic system: if the evolution of A's subset of the universe is as fast as possible or if all the observers must lack sufficient information about A to simulate it faster than A can evolve, then A can still have free will.
