Strongest claims in this topic
Astrology as psychological reflection
As a reflective prompt, astrology can function like any structured personality framework. Its value comes from the reflection, not the celestial mechanics.
Dream interpretation
Dreams reflect waking concerns. Universal dream-symbol dictionaries are mostly cultural; personal associations can carry meaning.
Tarot as reflection tool
Like astrology used psychologically, tarot can function as a structured reflection prompt with no claim to literal divination.
Sacred geometry encodes universal spiritual truths
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.
Angel numbers
A modern social-media phenomenon driven by selective attention. The brain finds patterns it is told to find.
Astrology determines literal life events

Curses — supernatural harm directed at a person or place
Believed in everywhere, supported by zero controlled evidence. Documented effects (illness, death after being cursed) are well-explained by nocebo, social ostracism, and chronic stress.
The evil eye — harm transmitted by envious gaze
A cross-cultural belief from Mediterranean to South Asian traditions, with elaborate protective practices. No evidence that the gaze itself does anything; the harm comes from the believing.
Key verified sources
Supports a limited evidence-based version of dream meaning: dreams can reveal recurring concerns and patterns without requiring prophetic or supernatural interpretation.
Useful companion to Carlson's Nature test because it surveys a broader evidence base rather than one double-blind experiment.
Foundational source for the Barnum/Forer effect, a central ordinary-cognition explanation for astrology, tarot, numerology, and psychic readings feeling personally accurate.
Useful skeptical source for sacred geometry because golden-ratio myths are a major pathway from real mathematics to metaphysical overclaim.
