Beyond the ψ‑Ontic and ψ‑Epistemic Divide: TMD as a Third Option

The Pusey–Barrett–Rudolph (PBR) theorem is widely regarded as one of the most important results in the foundations of quantum mechanics. It shows that, under broad and physically reasonable assumptions, the quantum wave function cannot be interpreted as a purely epistemic object. This conclusion has traditionally been taken to force a binary choice: either accept the wave function as ontic, or reject one of the theorem’s assumptions. This work presents a third option. Triadic Mesh Dynamics (TMD) provides an ontological framework in which the wave function ψ is not a fundamental physical entity, but an emergent statistical quantity summarizing the behaviour of a deeper, deterministic, and local triadic dynamics. In TMD, the ontic objects are the orientations of triads and their local flip dynamics, while ψ arises as a macroscopic description of orientational statistics, analogous to temperature in thermodynamics. Within this framework, distinct wave functions correspond to distinct statistical configurations of the triadic network, and TMD therefore automatically satisfies the empirical conclusion of the PBR theorem—without requiring ψ to be ontic. The result is a consistent third path: ψ is neither ontic nor epistemic, but emergent. This paper outlines the formal mapping between triadic orientation statistics and the emergent amplitude ψ, shows how the Schrödinger equation arises as the continuous limit of flip‑field dynamics, and argues that the PBR theorem naturally supports—rather than excludes—emergent ontologies such as TMD.
