I am at a loss here. I will admit I never read into Libet and his studies but how did no one notice the lack of control?
"In a new study under review for publication in the Proceedings of the National Academy of Sciences, Schurger and two Princeton researchers repeated a version of Libet’s experiment. To avoid unintentionally cherry-picking brain noise, they included a control condition in which people didn’t move at all"
I am at loss how is this connected to free will at all. I always though of it this way: If I was born with the exact same DNA and if I had the exact same experience as another person, given the exact same options, would I always make the same choice. If yes, then there is no free will. But it seems impossible to reproduce the exact same situation.
The idea is that the signals in the brain before the tapping of the finger were like a preparatory moment before the action so something ongoing in the brain prior to the decision to act hence there being the ability to determine action and thus free will.
