Every Mind a Universe: Quantum Decoherence, Cognitive Geometry, and the Moiré Structure of Intuition

We propose that the diversity of human cognitive experience—the fact that different minds do not merely hold different opinions about the same world, but appear to inhabit qualitatively different experiential realities—can be understood through the lens of quantum decoherence and its role in selecting classical pointer bases. Drawing on the Semantic Physics (SP) framework, we argue that genetics, accumulated experience, and transformative events (Folds) jointly determine the decoherence regime of each cognitive system, thereby instantiating distinct cognitive geometries: unique sets of robust basis states in the semantic Hilbert space. Intuition, on this account, is not a mysterious faculty but an interference phenomenon—a Moiré pattern that emerges when two distinct cognitive geometries are superimposed. Communication between minds becomes the temporary coupling of different decoherence regimes, generating a shared pointer basis that exists in neither alone. We formalize these ideas using the SP apparatus (Proto-∇, the Fold Principle, the MEMBRAN hypothesis) and outline empirical predictions that distinguish this framework from classical accounts of cognitive diversity.
