As I have got older (I'm in my early 50's) I have gained the ability to step back from situations and think about them from all sides. Sometimes that makes me more mellow about it, not always.
I'm not much into meditation but I have had experiences that viscerally proved to me that I am not in full control of my actions.
In my late teens and early 20's I developed a social anxiety, paruresis, which made it impossible for me to urinate in the presence of strangers. I could stand at a urinal, I could will myself to go as much as I wanted, nothing would happen. It felt very much like being a passenger in my own body. Happily, I was able to use graduated exposure therapy to make this manageable.
With kids I've also seen a lot of storymaking. A child will have an impulse to do something and when you ask them why, they don't know but they make up a story for it. I strongly believe we all do this. We act on impulse and then tell ourselves stories to explain our motivations and maintain a coherent sense of self.
Back in the early 2000's researchers were doing experiments on rats to remote control them via brain stimulation https://www.scientificamerican.com/article/researchers-guide...
The ethical aspects aside, my intuition is that if you wired up a human being with something similar you could remote control them to go left, right, forward or back. Afterwards you could ask them about their behaviour and they would explain it with a story in terms of their own free choices and decisions.
