Anomalous Phenomena and Consciousness: A Diagnostic Stress Test of Explanatory Frameworks

Abstract: Contested phenomena — from psychedelics to mediumship — have resisted clean integration into physicalist frameworks for decades. The resistance is not coincidental; it is diagnostic. This essay tests both physicalism and analytic idealism against ten such phenomena, organized by evidential maturity (Tiers 1–3) and argumentative role (Groups A–C). The central conceptual move is the distinction between mechanistic explanation — a constrained causal pathway specifying why this experience, this content, this timing — and dismissive labeling — "hallucination," "coincidence," "noise" — that classifies a phenomenon as unreal without explaining it. Where physicalism has genuine mechanisms, the essay credits them; where it relies on labels masquerading as explanations, the essay names what the labels do not do. The constraint theory enabled by analytic idealism — that the brain shapes consciousness rather than producing it — makes falsifiable predictions, and the essay states what would break the model. Group C phenomena (psi, mediumship, reincarnation) are the test case for whether the project's central diagnosis — that asymmetric restraint produces evidential gaps which are then cited as evidence of unreality — applies where prejudice is strongest. The argument does not establish idealism; it establishes that physicalism's apparent explanatory coverage often conceals refusal to explain.
