It's all about the physical components. Not having free will feels like sleep paralysis; it's a disconnection from your muscles.
Have you ever been playing an immersive video game, for example a story-driven FPS, and become completely used to looking around, moving etc. with the controls; and then hit a point where the developers take that control away to do something narrative? Suddenly your head turns to look at something and you didn't tell it to? The fraction of a second of vertigo and confusion, before you remember you're playing a game? That's no-free-will.
Feeling unable to complete thoughts I would like to think through, as if someone censored them
I can't make sense of this one. How would you even tell? You can't have an endless tower of meta-thoughts monitoring the first thought to see if it halted.
I don't remember that, but I do remember gorging my character on food because I was hungry.
Took me a minute to figure that one out.
Given the spike in free-will debates on LW recently (blame Scott Aaronson), and the usual potentially answerable meta-question "Why do we think we have free will?", I am intrigued by a sub-question, "what would it feel like to have/not have free will?". The positive version of this question is not very interesting, almost everyone feels they have free will most all the time. The negative version is more interesting and I expect the answers to be more diverse. Here are a few off the top of my head, not necessarily mutually exclusive:
Epistemic:
Psychological:
Physical:
For me personally some of these are close to the feeling of "no free will" than others, but I am not sure if any single one crosses the boundary.
I am sure that there are different takes on the answers and on how to categorize them. I think it would be useful to collect some perspectives and maybe have a poll or several after.
