This paper develops a unified framework linking subjective preferences, stock
market behavior, and quantum neuroscience, arguing that financial
decision-making originates in quantum cognitive processes rather than
classical neural determinism. Preferences, judgments, and ideas are modeled as
quantum states evolving within a cognitive Hilbert space, governed by a
preference Hamiltonian. These quantum states—subject to superposition,
tunneling, entanglement, and uncertainty—explain why investor behavior is
inherently probabilistic, context-dependent, and often non-rational. Market
prices emerge as observable outcomes of wavefunction collapse across
interacting agents, while crashes and bubbles are modeled through quantum
tunneling and collective decoherence. We derive a quantum uncertainty
principle showing that evaluation volatility and risk perception are
fundamentally bounded. Anomalies observed in behavioral and experimental
economics, including framing effects and preference reversals, are explained
through non-commuting cognitive operators and dynamic, operator-valued
utilities. This framework reinterprets market irrationality as a natural
consequence of quantum consciousness and provides a rigorous, empirically
consistent theory of financial behavior. |
