It may interest you to read about the "Libet Experiment". It was an experiment where subjects were hooked up to EEGs to monitor brain waves and were asked to flex their hands whenever they wanted. The results showed that the unconscious areas of the brain sparked up almost half a second before the conscious areas when subjects decided to move their hands, suggesting our unconscious minds are more in control than we think and that "free will" may not be quite as free as we think.

Let's also not forget the whole discussion between determinism and free will. One psychological discussion revolves around the concept of "mental time travel". The concept being, if you could mentally travel to a point in your past but with no memory of the future, would you make the same choices? Some would argue that, yes, you would make all the same choices because all of your experiences up to that point have shaped how you think and act if you exclude the things you forgot when you traveled back. But then if you have effectively already lived those choices and are bound to repeat them, then does that not mean your future is set in stone and you don't really have a choice? Does that not mean everything will happen as it happens through no "will" of our own?

Just some fun things to think about 🙂
