A research framework in cognitive science that uses the mathematical formalisms of quantum theory (like superposition, interference, and entanglement) to model human decision-making and judgment when it's ambiguous, context-dependent, or paradoxical. It doesn't mean the brain is a quantum computer, but that our cognitive uncertainties behave mathematically like quantum probabilities. It explains why your opinion can be in a superposition until you're forced to choose, or how asking a question (measuring) can change the answer.
Example: "I couldn't decide on the vacation. Quantum cognition explains it: my mind was in a superposition of 'beach' and 'mountains' until my wife asked 'Do you want sunscreen?'—collapsing my mental wave function instantly to 'mountains.' The question itself changed the answer."
