I ask because a lot of discourse here inevitably runs into questions about free will, without explicitly acknowledging it.
I can imagine a lot of people here admit to some degree of physical realism as well as to some degree of causal determinism. That however only solves how things work in the physical world, it does not explain why humans feel they are causal agents (whether or not they actually are; this notion of "actually are" being admitted by realists). Even if you have managed to personally convince yourself that "you have no free will", you can't deny the existence of millions of people whose conscious experience is one where they "feel" they are in control. You can't also can't deny that this feeling is usually partial - most people feel they are in control of some portions of their mental process and not in control of some other parts.
There is a lot of discourse on this site that implicitly assumes that people have partial control over their thoughts and actions. I'm not sure pointing at examples would provide an exhaustive list. But I do feel a lot of debates here on LessWrong would be clarified if we had a common understanding of this topic, so I thought it'd be a useful topic to bring up.
