Summary
Reference overview of the demarcation problem, common pseudoscience markers, and fields often classified as pseudoscientific by scientific bodies.
Why it matters here
General classificatory reference for weak-evidence claims such as crystals, numerology, and astrology. It should support caution and framing, not replace claim-specific tests.
Linked claims
Studies comparing real crystals to fake plastic ones consistently show identical (placebo) results.
A vast cross-cultural family of practices. Massive harm record (European witch trials, modern witch-killing); strict claim of supernatural causation has zero controlled evidence.
An ancient and modern system. No demonstrated accuracy beyond cold reading and Barnum effects.
Recurring geometric forms in nature and religious art are real and well-explained by physics, biology, and aesthetics. The metaphysical reading — that these forms encode universal truths — is the speculative part.
