(Since I will be sharing studies, this will be my last reply on the absence of free will, at least if there is no understanding)
Studies won't help you here. The question of if the will needs an internal reason to choose is a philosophical one, not an empirical once because the will is a conceptual faculty, not a material or bodily one
In our scenario, you can't move toward the button unless the proper signals in your brain are created in order for you to move. This means that physical signals precedes movement
You may not be able to move towards the button, but the question of the hypothetical isn't if your choice could come true, but if you could make a choice.
I may not be able to fly my flapping my wings, but I can still choose to want to do that even if my choice is unable to be fully realized due to me not being a bird
We also know that those physical phenomenons preceed the consciousness of our choices and our experience of will
This presumes the will is something physical and visible to us, a baseless assumption you will now have to prove for the sake of argument
All of your studies presume this as well. It's a baseless assumption. I reject it
This means that your movement of pushing the button could be predicted to happen exactly as predicted in around 99% of the tests
You haven't demonstrated anything.
Studies only show that in every particular observed instance, it follows a particular pattern or does so in a particular way
Your argument is that because the will
tends to move on account of some internalized reason, it
must
But again...with the swan example.
Just because only swans 3ft tall have been found, doesn't mean it's impossible for there to be a 3.2ft tall swan.
Just because the will has only ever been
observed to move due to some internalized reason, does not mean it's
impossible for it to move without one
