The Silence Paradigm: A Theoretical Framework and Protocol for Testing the von Neumann–Wigner Interpretation Using Controlled Observer States in Shielded Environments

Abstract

A foundational problem in physics remains unresolved: the role of the conscious observer in quantum measurement. This paper develops a theoretical framework, the Silence Paradigm, that generates testable predictions bearing on that problem. It treats the observer's state of consciousness as a controlled experimental variable rather than as a philosophical assumption, and asks whether the decoherence rate of a nearby quantum system varies with that state. The framework proposes that as a conscious observer approaches minimum cognitive excitation, operationalised by EEG patterns consistent with minimal phenomenal experience and full cessation, the decoherence behaviour of a nearby shielded quantum system changes measurably. The primary prediction is specific and directional: coherence times will exceed the empty-chamber baseline at the two deepest conditions, with the largest effect at cessation. Because the empty-chamber baseline sits inside the comparison group, the prediction commits the framework to a coherence-protective contribution rather than merely to the absence of a decohering one. A reversed sign is pre-registered disconfirmation. The paper surveys the interpretive landscape it is positioned against, including the von Neumann-Wigner interpretation, orchestrated objective reduction, QBism, the decoherence programme, and the objective-collapse bound-setting tradition, and states plainly where the framework has a mechanism gap rather than a mechanism. It addresses seven standing objections directly, including unfalsifiability, thermal decoherence in warm wet tissue, the shielding paradox, and the somatic-stillness confound. It sets out the outcome scenarios in advance, including the suppression pattern, which is a distinct result and not a confirmation. The expected outcome is a null. That is the prediction of environmental decoherence theory, it is pre-registered as publishable, and it yields the first point on an exclusion plot rather than a filed-away negative. The scientific value of the work does not depend on the hypothesis being correct. This is the theoretical paper of a four-document programme. The experimental protocol is set out in The Silence Experiment, the chamber specification in the companion engineering blueprint, and the statistical basis in the companion power analysis and study design table. The protocol is pre-registered at OSF. This work is not peer reviewed, no chamber has been built, and no data have been collected. Changes in this version. The previously proposed Phase 1, a superconducting transmon in an underground laboratory conditional on a positive Phase 0 result, is withdrawn, and the reasoning is given in the text rather than removed silently: the sensitivity argument was mistaken, and gating a second experiment on the first succeeding makes the expected outcome terminal. Phase 1 is redefined as an isotopically purified sample in the same chamber, not conditional on any Phase 0 result. Budget figures are corrected following an arithmetic audit of the bill of materials. Session structure is revised to chained conditions. No repository identifiers appear in the document.
