But it's a meaningless decision, more of a random selection than a choice.
Try attaching meaning, something the subject cares about that requires a bit of thought. If pushing the left button means choosing a wife vs the field, a cheaper state school vs a private school, killing ten children vs twenty adults, will the brain scanner reveal my decision before I'm aware?
The researcher becomes conscious of a decision, 6 seconds before his subject becomes conscious of a decision he makes. 6 seconds is a very long time.
I don't see it as proof of anything other than that. Time itself is still mysterious.
It could be interpreted to mean, we act first and then consciousness comes in a later stage, as though we are slaves to our neurons and our consciousness comes along for the ride, which is determinism in a nutshell.
Or, perhaps it's more correct to think our actions and consciousness are intertwined somehow. I know that if touch fire, it's a bad idea because of my consciousness, so my consciousness dictates not to touch fire in future?
Take that with a pinch of salt, I'm just thinking while I'm typing and not sure it's relevant.
As for your question, I'd imagine the scanner would detect in advance those actions in advance yes.
Free will is just what we call, when we are faced with a decision. Whether it's left or right, kill someone or not.
Michio Kaku believes in free will due to Heisenberg's uncertainty principle.
If you rewound the clock to the creation of the earth and then roll forward to now it would not be the same. The nuerons are leaky and messy and have quantum effects. Though the brain is largely deterministic. You can see that a psychopaths brain is wired differently than ours. Ahhh, seems contradictory.
I believe the thoughts that enter my head are random though. I don't feel guilty for any thought that enters my head. It's only when I carry out an action that's harmful I feel guilty. I'm okay with that.
It's whether this whole thread was determined at the big bang, assuming that theory is true, is what I'm not uncomfortable with. How could anyone be?
maybe these age old questions are there to never to be answered.
