MERLIN SCIENCE — Quantum Interference in Social Decision-Making: A Quantum Cognition Mo — E8 Intelligence Research

The finding is this: human decisions under uncertainty and social conflict can be modeled not with classical Bayesian probabilities, but with quantum probability amplitudes, where interference terms capture the effect of social interaction on choice. That's the one clean sentence. For context, this sits in quantum cognition, a field that has spent two decades showing that people violate the sure-thing principle and other classical axioms in predictable ways. The standard response has been to patch classical models with extra parameters. This work takes a different route, borrowing the Hilbert-space machinery from physics and applying it to cognitive states. Here's the mechanism you can evaluate. Instead of assigning a probability to an event, you assign a complex amplitude. The probability is the squared magnitude of that amplitude after projection onto a subspace. When you have two possible answers, A or B, the classical sum of their separate probabilities is not what you observe. Y Author: Andrew Stewart Caldin, Independent Researcher, UK.
