A Proof of Bell’s Inequality in Quantum Mechanics Using Causal Interactions
Talkat Quantum Physics and Statistical Causal Models (Simons Institute workshop, 2022) · 2022-04-27..04-29
summary
A compact, concrete proof shows that Bell inequalities follow from standard counterfactual (Neyman) causal-interaction logic and that experimentally observed sine-squared correlations (confirmed by randomized angle choices) force a contradiction with local realism. The argument constructs the binary indicator M_ij (same-spin) and proves a specific mean contrast > 0 implies the existence of a unit with pattern 1,0,0,0, which is impossible under no-interference/local-hidden-variable assumptions. The proof borrows causal-inference tools and maps to epistatic interaction tests; no-signaling remains intact.
