Quantum Interference in Social Decision-Making: A Quantum Cognition Model — E8 Intelligence Research

FINDING: Quantum cognition models human decision-making under uncertainty and conflict using quantum probability amplitudes rather than classical Bayesian logic, with social interaction effects incorporated via quantum interference terms. | MATH: Quantum probability: \( P(A) = |\langle \psi | \hat{P}_A | \psi \rangle|^2 \), where \(\hat{P}_A\) is a projection operator; interference term: \( P(A \lor B) = P(A) + P(B) + 2\sqrt{P(A)P(B)}\cos(\delta) \), with \(\delta\) the phase difference; social agents: density matrix formalism \(\rho \to \sum_i w_i \rho_i\) with Lindblad-type evolution for interaction-induced decoherence (arXiv:1202.4918v2). | CONNECTION: The interference phase \(\delta\) is not fixed by the sources; no explicit golden-ratio or base-60 constants appear in the cited abstracts. However, quantum interference amplitudes naturally produce oscillatory probability patterns — if \(\delta = \pi/5\) (36°) or \(\pi/3\) (60°), the interference term yields ratios involving \(\cos(3
