Flim-Flam! Psychics, ESP, Unicorns, and Other Delusions is a 1982 book by magician and skeptic James Randi about paranormal, occult, and pseudoscience claims. The foreword is by author and biochemist Isaac Asimov.
Randi explores topics which he says that scientists and the media are too willing to promote without skepticism and proper expertise. A New York Times review said it is "a healthy and often hilarious book.
Currently the book is available in English, Norwegian, Polish, Spanish, Italian, and Chinese.
Although unicorns are prominently mentioned in this book's subtitle, the one and only reference to these mythical beasts in the book's text is in Randi's brief and dismissive preface on the first page. Possibly they were included to give the title an undertoned example of mythological fortitude that promotes itself into the global atmosphere of beliefs that are represented as psychological fakery.
