Good points even though I have problems with both of the tests done on reaction time, based on the difference between decisions, preparing to decide, becoming willing to act and actually acting. I also take Martin Heisenberg's point about two step free will, the personality points us toward a group of choices and then we have a secondary social layer that actually makes the choice.

In the final analysis free will is "real enough", as a species we have learned that acting as if we, and others, have free will works. Punishment and reward works, encouragements work, peer pressure works, because free will seems to be real enough.
