When the body's chemical balance is disturbed, the physical world perceived by an individual changes accordingly, because sensory data become distorted.

当身体化学平衡被扰乱时，个体感知到的物理世界会相应改变，因为感官数据会出现扭曲。

This program treats the Seth Material as a source of hypotheses, not as doctrine to be validated. Lead dossiers are AI-compiled from the corpus with a book-and-session citation after every statement; literature reviews are AI web-search summaries whose references were all DOI-verified against Crossref; the agenda draft is an AI synthesis. None of it is Seth's original text, and none of it represents scientific consensus. English fields are machine-translated; the Chinese text is authoritative.

Adjudicating experiment

For issue 2, under approved clinical research conditions, pre-register a randomized crossover trial with about 80–120 participants, comparing placebo, 5-HT2A agonist, antagonist, and combined conditions, with adequate washout. Measure contrast and motion discrimination thresholds, illusion susceptibility, d′, and decision criterion; simultaneously collect blood for drug exposure and record EEG; 4 sessions per person, over 18–24 months. Use receptor blockade to test causal specificity; dopamine manipulation should be tested in a separate trial.

What it would overturn

No mainstream hypothesis needs overturning; the influence of neurotransmitter receptor activity on sensory processing and perceptual experience is already an established conclusion in neuropharmacology.

Specificity of Seth's formulation

The directional claim is compatible with science, but it specifies no transmitter, receptor, dose, perceptual dimension, or time course, making it less specific than existing pharmacological hypotheses.

Note

The 'supported' rating is limited to 'specific neurochemical changes can alter perception'; it does not mean any chemical change necessarily causes distortion. Plasma 5-HT or dopamine cannot directly serve as measures of brain neurotransmitter levels.
