I feel as if the answer to this is, by general consensus, yes. You have free will.

Like, does Evil exist? Scientifically? No, absolutely not, but the word still has meaning. If I say, "that man is evil!" And you look at him and recognize his terribleness, then, sure: he is IS evil.

Just because something isn't objectively, physically quantifiable, doesn't mean that it's not a valid rational construct.

I think the actual argument which has been making the rounds recently, is not, "do humans have free will?" But, Rather is, "are humans accountable for their actions, given that thier will is significantly biased by factors outside of their control / awareness?"

It's just that doesn't get people's attention.

Ps, I believe that fundamentally, all physical interactions are deterministic in practice. Any conscious or rational being is fundamentally set in motion with the arrow of time, and if you could develop a fuzzy quantum state based intelligence, you'd only succeed in creating a person with slightly more random ideas. There would be no meaningful uplift in "free will." However, I also Believe that this is an absurd deconstruction of heady topics. It's akin to telling someone that a table doesn't exist because it's just a decomposing tree. Free will is a rational idea for human animals, and judged by that standard, fulfills it's purpose in describing the experience of conscious decision making.
