PFUSRC-055E: The Ontological Restoration of the Pendulum—From "Ideomotor Effect" and "Probability Theory" to Ψ-Ξ Dual-Anchoring Ontological Reconstruction, with a Discussion on the Projection Mechanism of Human-Cosmos Homology

Pendulum dowsing is a cross-civilizational traditional technique yet has long been labeled pseudoscience by mainstream modern academia. Mainstream scholarship attributes pendulum motion to the ideomotor effect, subconscious reflexes or random probabilistic coincidence. Based on the Ψ-Ξ dual-anchoring theoretical mechanism established in PFUSRC-17, this paper reanalyzes historical records and scientific verification cases of pendulum dowsing to achieve a paradigm reversal: the pendulum is not a mystical ritual tool, but a physical detection medium. Through Ψ-Ξ dual anchoring, the human body leverages the pendulum as a mechanical amplification interface to capture external Ξ-type field targets. The core reason behind the effectiveness of pendulum detection lies in the isomorphic homology between human beings and the cosmos: the human body itself is a three-dimensional projection of the universal rigid topological skeleton, innately containing both Ψ (Noetic) and Ξ (Affective) functional terminals that can be trained and activated. Pendulum dowsing does not create new connections between separate entities, but re-establishes the obscured projection linkage between humans and cosmic ontology. This paper systematically sorts three independent historical case clusters: German comparative contests between dowsers and geologists (1910s–1930s), British archaeological verifications at Durham Cathedral (1980s), and U.S. military dowsing applications during the Vietnam War (1960s). It refutes the interpretative defects of the ideomotor effect and probabilistic coincidence theories, and ultimately restores the primordial scientific identity of pendulum dowsing.
