Experimental violations of Bell's inequality provide decisive empirical tests that can definitively falsify entire classes of theoretical explanations.

Evidence for

Conclusions the firm has recorded that cite this principle or sit in its supporting cluster.

• Bell's inequality provides a falsifiable test between hidden variable theories and quantum mechanics: if the inequality is satisfied, hidden variables are consistent with the data; if violated, no hidden variable theory can explain the correlations.

• When Bell's inequality is experimentally violated, hidden variable theories of quantum mechanics are falsified — the violation constitutes a decisive test between local realism and quantum mechanics.

Evidence against

Open-tier conclusions in the same cluster — claims the firm has not yet promoted to firm or founder confidence, and which would weaken this principle if they hold up.

• Einstein proposed that there are hidden variables in quantum mechanics.

• Bell's theorem demonstrates that no local hidden variable theory can reproduce the predictions of quantum mechanics, ruling out deterministic explanations that preserve locality.

Decisions this informs

Example decisions the firm would consult this principle for. Each links to the conclusion that registered the example.

• Reject local hidden variable interpretation if experimental S > 2 in CHSH test.
• Design Bell test protocol to close detection loophole before claiming quantum nonlocality.
• Use Bell violation as criterion for certifying quantum entanglement in device-independent protocols.
• Reject local realism interpretations when CHSH inequality shows S > 2.8 with p < 0.001.
• Accept quantum mechanics over classical theories when aspect-type experiments close detection and locality loopholes.
• Route superdeterministic theories to separate evaluation since Bell violation doesn't directly falsify them.
• Reject any quantum interpretation proposal that relies on local hidden variables as inconsistent with Bell test results.
• Design quantum cryptography protocols assuming no local realistic explanation for entangled state correlations.
• Evaluate quantum computing architectures based on non-local correlation exploitation rather than classical deterministic models.
