James T. Kirk under hypnosis.

Hypnosis was a psychological technique. It produced a trance-like state in which one was relaxed and more susceptible to suggestion. One who hypnotizes was called a hypnotist.

Hisory and specifics

Hypnosis relaxed a person's inhibitions and was a delicate process. (TOS - Mudd's Angels short story: "The Business, As Usual, During Altercations")

Alpha hypnosis would not force someone to break their own morals, but could alter their perception or understanding of an event. (TOS novel: The Prometheus Design)

It is a popular method of restoring repressed memories. (VOY novel: Cybersong, TLE novel: Deny Thy Father)

It could be used to verify the truth of reported statements. (TNG - A Time to... novel: A Time to Die)

In the 20th century, hypnosis was used to examine people reporting to have been abducted by extraterrestrials. (TOS novel: The Prometheus Design)

In 2270, Leonard McCoy performed hypnosis on Pavel Chekov as a means to help him imagine being Harry Mudd, to help track down Mudd's Superstella. McCoy was uneasy tampering with the officer's inhibitions, but Chekov said he trusted the doctor not to harm him. It worked – Chekov suggested the planet Sarai, and Mudd was located in that sector. (TOS - Mudd's Angels short story: "The Business, As Usual, During Altercations")

In February 2274, Captain Morgan Avery suspected that the armed mobilization of Husians on Hus-24 against Starfleet was a result of hypnotism by their spiritual leader, Edrem. (TOS comic: "Husian Gambit")

In 2375, Beverly Crusher used hypnotism to treat Colin Blakeney's temporal shock. Hypnosis allowed Blakeney to accept Data, Deanna Troi and Crusher as participants in holodeck simulations of his past, in order to help him reintegrate his memories. (TNG comic: "Forgiveness")

In 2376, The Doctor was susceptible to hypnosis. (VOY episode: "Spirit Folk")


While he was in stasis, 20th century Doctor Alfred Bleikoff was surgically altered: his brain was replaced with an electronic brain capable of generating a mass hypnotic effect.

In 2267, Kor thought that the Organian phenomena of weapons radiating at high temperatures was an affect of hypnosis.

(TOS - Star Trek 2 novelization: Errand of Mercy, TOS novel: Spock Must Die!)

Klingon Professor Karkax used a mechano-hypnotiser to perform mass hypnosis on the Lothorian administration, then on the crew of the USS Enterprise. They were ordered to crash the starship into the capital of the Federation, and the ploy would have succeeded except that Spock's Vulcan physiology was able to overcome the hypnotism. (TOS comic: "By Order of the Empire")
