Psi & Anomalous evidence.
Lab-tested claims of telepathy, precognition, remote viewing, and PK. This hub collects the relevant claims, strongest and weakest evidence positions, source records, and map/library views for the cluster.
What Psi evidence actually supports
Psi is strongest when treated as a contested anomaly literature rather than as proof of consumer psychic powers. The best pages compare small statistical effects, spontaneous reports, and methodological objections in one place.
- Ganzfeld and free-response studies provide the most developed lab tradition for telepathy-style information transfer.
- Precognition and presentiment claims have modern experimental and meta-analytic sources, especially Bem-style and Mossbridge-style work.
- Remote-viewing evidence is most useful where it uses formal protocols, independent judging, and the Stargate-era Utts/Hyman evaluation split.
- Micro-PK research on random-number generators has meta-analytic evidence for tiny effects, but practical meaning is highly contested.
- Effect sizes are usually small and replication is uneven.
- Sensory leakage, file-drawer effects, optional stopping, multiple comparisons, and flexible analysis remain serious concerns.
- Macro-PK claims such as levitation or object movement have not survived the same level of scrutiny.
- Commercial psychic claims often overstate a literature that, at best, supports weak and contested anomalies.
Psi evidence does not prove reliable psychic powers, a known mechanism, spirit communication, or practical forecasting ability. It does support careful study of a small set of contested anomaly claims.

Strongest claims in this topic
Remote viewing
The CIA's declassified Stargate program ran for two decades and reported above-chance results. The official 1995 review judged the operational utility insufficient.
Telepathy
Decades of ganzfeld and card studies report small effects at meta-analytic level. Critics argue methodological flaws explain them.
Precognition
The reported experience of knowing, sensing, dreaming, or picturing a future event before it happens — sometimes called premonition, presentiment, future sensing, or anomalous anticipation. Real as a common human report; controversial as evidence the future is being directly perceived.
Clairvoyance
Often subsumed under remote viewing in modern parapsychology. As an everyday claim, very poorly supported.
Intuition can exceed normal inference
Most 'intuition' is unconscious inference. A small subset of presentiment studies suggests something else may also be in play.
Animals can sense distant events
Anecdotes of dogs anticipating their owner's return or sensing distant trauma are common. Controlled video studies show some signal, contested.
Weakest or most speculative claims
Humans can physically levitate
A tradition rich in reports — Joseph of Cupertino, Daniel Dunglas Home, TM 'yogic flying' — but zero reproductions under controlled conditions. The investigated cases reduce to fraud or illusion.
Animals can sense distant events
Anecdotes of dogs anticipating their owner's return or sensing distant trauma are common. Controlled video studies show some signal, contested.
Precognitive dreams
Given how many dreams we have, occasional 'matches' are statistically inevitable and powerfully memorable.
Psychokinesis
Famous macro demonstrations have collapsed under scrutiny. Lab work on random event generators shows very small effects, hotly disputed.
Key verified sources
Classic pro-ganzfeld anchor; strongest historical source for telepathy-style lab evidence.
Direct replication challenge to the ganzfeld literature; must sit beside Bem/Honorton.
Later positive meta-analysis; useful only when paired with Hyman's critique.
Methodological counter-anchor for the Storm meta-analysis and broader psi inference.
Positive Stargate-era assessment; best read against Hyman's same-program critique.
Modern statistical objection source for Bem-style precognition claims.
Does psi exist? Replicable evidence for an anomalous process of information transfer
A central pro-psi anchor for ganzfeld/free-response claims, especially telepathy-style information transfer under sensory-reduction conditions.
Does psi exist? Lack of replication of an anomalous process of information transfer
The classic skeptical replication counterpoint to Bem and Honorton, useful for keeping ganzfeld pages from presenting a one-sided meta-analytic story.
