“Physics shows that humans do not truly control their choices, so free will is probably not real, though believing in it helps self-efficacy.”

“Physics raises deep questions, but it does not settle your agency so neatly.”
The classical deterministic thought experiment is a recognizable argument: if the complete past and laws fixed one future, some definitions of free will would be threatened. It is also reasonable to say that mere randomness would not automatically create deliberate personal control. The post correctly identifies emergence as a serious way of discussing higher-level properties such as cognition.
The video treats the incompatibility between determinism and free will as settled, but compatibilist accounts explicitly argue that agency can consist in acting from one’s own reasons, values, and capacities even if events have causes. It also presents quantum mechanics too simply: standard quantum measurements can have probabilistic outcomes, but quantum theory has competing interpretations and does not establish that brain-level choices are simply random. Knowing every particle’s initial position is not an accepted route to predicting everything in our actual universe.
Yes. A reasonable viewer could leave believing physics has demonstrated that they have no control over action. The omitted philosophical disagreement and unsettled interpretation of quantum theory materially change that conclusion.
Why Clear says this
The post’s core argument is philosophically plausible as one route to skepticism about a particular, libertarian version of free will. But science does not currently decide whether meaningful human agency exists, because that depends on contested definitions of control and on unresolved interpretive questions. Evidence that belief in free will improves self-efficacy or behavior is also mixed and does not justify a broad practical prescription.
Evidence
- Classical causal determinism would create a challenge for free will only under incompatibilist definitions that require genuinely open alternative futures.
- Compatibilism is a major position holding that free will can be compatible with determinism.
- Quantum experiments support probabilistic measurement outcomes in standard quantum mechanics, but this alone does not resolve the metaphysical free-will debate.
- Research on experimentally weakening free-will belief has had replication and measurement disputes; it cannot establish that believing in free will is necessary for self-efficacy.
