I've never heard a credible explanation of free will or what someone means by that. Can you offer a description of what free will means, within known science?
I think it through several layers. At a personality layer most of the time you make decisions that are consistent with your personality. But occasionally you do something out of character.
At a lower level, a mind logic level, your mind / brain makes decisions based on weights. Should I have a coffee now - do I want one, do I enjoy it, am I trying to avoid caffeine because I felt a bit fuzzy yesterday etc. The bigger the decision the more weights go into it, but if you re-ran the same mind with the same weights then it makes the same decision every time, and if it didn't then er why? So where is the freedom there? To make a free choice at this level is to make a choice inconsistent with the experience + inputs of the mind.
Then at the lowest level, the brain is processes in the physical universe. Quantum probabilistic effects, as I understand it, don't have much effect on outcomes. And where they do, it's not like your brain controls that, it just happens. We have a physical state, time goes forward and we have a new state. And that's all there is, no concept of will, free or otherwise.
And you know, I think it's perfectly fine to feel like you have free will and not consider it often. Live your life as if you do. It's only if you focus on it that you can be like "ah, probably not then" but does it matter?
