With the exception of a few fringe idea's like Penrose (Shadows of the mind, Emporers new mind) academic consensus in relation to models of the Physical universe suggest a fundamentallly deterministic universe.

Penrose implicitly suggests that large scale quantum cooherence in the human brain allows for quantum uncertainty to act as an interface for free-will to interact with the physical universe.

Most scientist would agree that this is pseudo-sceintific speculation at best, and more likely misleading nonsense.

None of the widely used physical models of the universe include equations such as E=mc^2+(D) where D is David's next decision.

While the models currently used do place limitations on "predictability", they do not suggest anything other than a fundamentally deterministic universe.

That free-will exists at the level of experience is clear, the rational implication of accepted scientific models is however that experience of free will is simply a phenomenon.

The suggestion is thus that decisions percieved as "free-will" are fundamentally consequential.

Any suggestion to the contrary, indicating that decisions of a "mind" external to the physical system can alter the determistic nature of causal physical relationships, would require a rewriting of accepted scientific models of the physical world.

Your can browse for such attempts on google (quantum consciousness etc.)
I rank them alongside "action flop theory" and "**** poker is rigged".

Good luck
