Spin and Wind Directions I: Identifying Entanglement in Nature and Cognition

Area of Science:

• Cognitive Psychology
• Quantum Mechanics
• Foundations of Science

Background:

• Bell's inequality, specifically the CHSH version, is a cornerstone in testing quantum mechanics.
• Entangled quantum systems exhibit correlations that defy classical explanations.
• The application of quantum principles to cognitive phenomena is an emerging interdisciplinary field.

Purpose of the Study:

• To investigate whether human cognition of conceptual entities, like wind directions, exhibits quantum-like correlations.
• To compare the structure of cognitive associations with the phenomenon of quantum entanglement.
• To explore the potential for quantum modeling in understanding human decision-making processes.

Main Methods:

• A cognitive psychology experiment was designed where participants selected pairs of spatial directions representing distinct wind directions.
• The collected data were analyzed for violations of the Clauser-Horne-Shimony-Holt (CHSH) inequality.
• The magnitude of the observed violation was compared to typical Bell-test experiments using entangled spins.

Main Results:

• The experimental data demonstrated a violation of the CHSH inequality.
• The magnitude of this violation was comparable to that observed in physical experiments with entangled spins.
• This suggests that conceptual entities, such as wind directions, are linked through meaning in human cognition in a manner analogous to quantum entanglement.

Conclusions:

• Human cognition of conceptual entities can exhibit correlations analogous to quantum entanglement.
• The findings suggest a potential framework for applying quantum mechanics to understand cognitive processes.
• This study provides foundational insights for further quantum modeling of cognitive data, as detailed in subsequent work.
