If your complaint now is that the article on quantum tunneling is not "how-y" enough, please note that I am not asking for a description of free will at that level. A description at the level of a Turing machine would be just fine. My problem is not that I don't understand the physics of free will. My problem is simply that I do not understand the high-level repertoire of decision-making methods that are available to the free agent.
