Consciousness and psi concerns alleged capacities of mind that exceed established sensory, cognitive, or motor processes. Psi is an umbrella term for telepathy, clairvoyance, precognition, psychokinesis, and related effects. The subject differs from consciousness science, which studies measurable relations among brain states, behavior, and experience; psi adds a proposed transfer of information or influence without a known conventional channel. That additional claim is what makes controlled blinding, preregistration, and replication especially important. Experimental claims therefore depend heavily on excluding unnoticed conventional cues.

Laboratory parapsychology has used card guessing, ganzfeld telepathy, random-number generators, presentiment measures, and remote-viewing targets. Some meta-analyses report small statistical effects, while critics identify selective reporting, methodological flexibility, sensory leakage, and difficulty reproducing results under tighter controls. The dispute persists because effect sizes are generally small and no accepted mechanism links the claims to physics or neuroscience.

Government interest gave the topic unusual institutional history. U.S. intelligence agencies funded Remote Viewing research under programs eventually grouped as Stargate. A 1995 evaluation found that laboratory results warranted further study by one reviewer but that operational intelligence value had not been demonstrated, and the program ended. The records prove investigation of psi, not a settled finding that it worked reliably.

UAP communities connect psi to contact, “summoning,” downloads, and altered states reported by witnesses. The Immaculate Constellation Report is sometimes read through that lens, though its core claims concern intelligence collection rather than proof of psychic causation. Consciousness-and-psi remains a disputed research domain whose historical programs and subjective reports are documented more securely than the proposed abilities themselves.
