Psychics, ESP, Unicorns, and Other Delusions is a 1980 book by magician and skeptic James Randi about paranormal, occult, and pseudoscience claims.

"will enlighten any reader who does not clearly understand that not one shard of evidence exists to prove that the Bermuda Triangle poses any special menace to ships and planes, that earth is being visited by alien spacecraft, that the unassisted power of the mind can read closed books, predict our future or induce levitation, or that the 'psychic surgeons' of the Philippines have relieved their patients of any burden more troublesome than their money.

"[1] Randi levels criticism at the sloppy study designs and faulty controls of the investigations into remote viewing by Russell Targ and Harold Puthoff.

[4][5] Randi writes the public is badly served by scientists investigating the paranormal who don't adhere to the standards of their profession and shows how sloppy research was followed with rationalization of their failures.

[8] The Transcendental Meditation movement and Edgar Cayce's mystic medical practice are subjected to Randi's skeptical scrutiny.

[12] In these anecdotes the reader learns some of the methods used by charlatans including how to guess cards, tilt tables, read while blindfolded and produce photographs.

[1] Ferris cited Randi's "penchant for sarcasm and overemphasis" as a drawback and considered this "heavy-handedness" appropriate for charlatans who profit from fraud but less so for sincere if gullible true-believers.

"[2] The magazine describes the anecdotes about cases Randi was involved in as a judge or expert as absorbing and states they go far to make the point, "if you design the experiment adequately, no extraordinary powers are demonstrated."

concluding, "By the end of the book, Randi's personal offer of $10,000 to be paid to anyone who successfully demonstrates paranormal abilities under proper test conditions seems safe beyond a doubt.

is an excellent overview of paranormal claims that analyzes medical humbugs, psychic photography, Transcendental Meditation, ancient astronauts, UFOs, etc.

"[15] In a review of the audiotape edition in the Journal of College Science Teaching George Kauffman wrote of Randi's analysis of the failures of paranormal "researchers", "In clearly pointing out their errors and misrepresentations, he provides a compelling and convincing case that will startle and enlighten the listener, especially one unable to distinguish between genuine scientific research and the pseudoscientific nonsense that results in fantastic theories and fallacies.

[23] The publication run by Harper & Row was planned to be 17,500 but was reduced to about 6,000 and the book was declared out of print by the publisher despite outstanding paid orders.
