The Expiration Date of Object Permanence: Heuristics, Grammar, and Quantum Pseudoproblems

Object permanence is among the earliest and most successful cognitive heuristics acquired in development, enabling agents to navigate a world of occluded objects, stable boundaries, and rapid environmental interaction. While indispensable at macroscopic scales, this heuristic is rarely recognised as provisional. Instead, it is often tacitly promoted into an ontological assumption: that reality itself must consist of persistent, bounded objects with determinate identities across time. This paper argues that many of the apparent paradoxes surrounding quantum superposition, entanglement, and measurement arise not from exotic features of the physical world, but from the uncritical extension of object-based heuristics beyond their domain of validity. Drawing on developmental psychology, philosophy of language, and recent matter-wave interference experiments with increasingly massive nanoparticles, the paper shows that object permanence fails neither mysteriously nor universally, but predictably and quantifiably under conditions where environmental decoherence is deliberately suppressed. By reframing quantum discomfort as a pseudoproblem generated by heuristic overreach and grammatical reification, the paper offers a deflationary account of several longstanding debates. The conclusion is not that common-sense object descriptions are false, but that they are local tools whose limits can now be empirically mapped. The task of philosophy, on this view, is not to repair reality, but to clarify when our descriptive practices cease to apply.
