What does that mean? If I'm not forced by the laws of physics to choose X over Y, then it sounds like I have free will? No. I can't choose to defy the laws of physics but I can choose to defy things like self-preservation. If I'm on a street corner and there is a bus speeding past me, I can choose to defy the feeling to avoid the bus. That seems like free will to me.
What you’re describing isn’t free will in the sense of independence from causality. Your ability to step in front of a speeding bus isn’t some magical override of physics; it’s still a result of the causal chain that led to that moment. Let’s unpack this.
The “choice” to step in front of the bus is shaped by countless prior factors: your mental state, past experiences, and current context. Maybe it’s an impulsive decision, a calculated act of defiance, or even the result of emotional turmoil. Whatever the case, those contributing factors—many of which are outside your conscious control—determine the outcome. Your brain processes the situation and reaches a decision based on its wiring and inputs, all of which follow deterministic principles.
The laws of physics don’t “force” you to act a certain way, but they provide the framework within which all causality operates. Choosing to defy self-preservation doesn’t escape causality; it simply reflects the complex web of prior causes that makes such a decision possible. The feeling of defiance, like all decisions, emerges from deterministic processes.
The sense of “free will” comes from our subjective experience of weighing options,
but neuroscience has shown that decisions are made in the brain before we’re even consciously aware of them. That doesn’t make the choice less real—it’s just not independent of the causal factors that brought it about.
Stepping in front of the bus is still part of a deterministic system. The fact that you could imagine multiple options doesn’t mean the choice you made was free; it means your brain evaluated inputs and arrived at one inevitable outcome based on prior causes. The illusion of freedom is powerful, but it doesn’t mean we’re escaping the deterministic web.
Again, it sounds like you are saying one thing and then contradicting it in the next sentence (see the red highlighted type).
Unless I'm mistaken, I believe there have been various ways of interpreting the results of the experiments. Unless I'm mistaken, the jury is still out among thoughtful people as to whether there is free will or not.

Benjamin Libet's experiments have been interpreted to challenge the idea of free will, but the interpretation is debated:
The experiment
In Libet's experiment, participants flexed their wrists whenever they wanted and reported when they became aware of the intention to flex. The results showed that brain activity associated with the decision to flex preceded the conscious intention to move by several hundred milliseconds.
Interpretation
Some interpret this to mean that the brain makes decisions before we are aware of them, and that unconscious processes determine our decisions. This has led to discussions about whether the brain, rather than free will, initiates voluntary acts.
Debate
However, others argue that the common interpretation of Libet's experiments is questionable. They argue that the brain activity preceding conscious decisions reflects the decision process rather than its outcome.
Meta-analysis
A meta-analysis of Libet-style experiments found that the results were largely consistent with Libet's findings, but there was a high degree of uncertainty. The authors concluded that some of Libet's findings may be more fragile than anticipated

Gary, let’s ground this discussion in the conservation laws and physics to clarify the deterministic framework and address your concerns about contradiction.
The laws of conservation—energy, momentum, charge, etc.—are foundational to all physical interactions. They tell us that every action, including neural activity and decision-making, involves the transfer and transformation of conserved quantities. This means that every process, from a star forming in space to a neuron firing in your brain, is governed by these principles. In a deterministic system, such as the universe described by these laws, every event is causally linked to prior events.
Now, regarding your example of stepping in front of a bus:
1. Determinism and Possibility: The laws of physics do not "force" you to choose X or Y (in this case, stepping into traffic or not). Rather, they provide the framework within which all causes interact. Your decision arises from a web of factors—your experiences, neural patterns, and external stimuli—all of which adhere to the conservation laws. There’s no contradiction here; your choice is simply the inevitable outcome of this interplay.
2. The Illusion of Free Will: It might feel like you’re defying self-preservation, but that feeling is part of the causal process. Your brain, operating under deterministic laws, evaluates options, processes emotions, and arrives at an outcome. The subjective experience of “choosing” is real, but it doesn’t mean the choice is independent of causality.
3. The Libet Experiment Debate: The conservation framework aligns with the findings of Libet and others. If brain activity predicts decisions before conscious awareness, it supports the idea that decisions originate in unconscious processes. These processes are still physical and deterministic, governed by the same conservation principles. Debates about interpretation don’t change this; they merely refine our understanding of the causal mechanisms.
To address your concern about contradiction: when I say the laws of physics don’t “force” you to act, I mean they don’t prescribe specific outcomes like a command. Instead, they govern how outcomes are causally linked. Your "choice" isn’t forced in a coercive sense but is determined by the factors at play, all of which obey these physical laws.
Finally, let’s be clear: if we were to find evidence that decisions could violate the conservation laws or operate independently of prior causes, determinism would be upended. But so far, no such evidence exists. Until then, free will remains a powerful illusion created by the deterministic processes that shape our thoughts and actions.
