Extrasensory Perception is a 1934 book written by parapsychologist Joseph Banks Rhine, which discusses his research work at Duke University.

Extrasensory perception is the ability to acquire information shielded from the senses, and the book was "of such a scope and of such promise as to revolutionize psychical research and to make its title literally a household phrase".

[4][5] Rhine's experiments were discredited due to the discovery that sensory leakage or cheating could account for all his results, such as the subject being able to read the symbols from the back of the cards and being able to see and hear the experimenter to note subtle clues.

The psychologist C. E. M. Hansel wrote, "it is now known that each experiment contained serious flaws that escaped notice in the examination made by the authors of Extra-Sensory Perception After Sixty Years".

[14][15] Psychologist Carl Jung referred to Rhine’s work as scientific proof that part of the psyche is not subject to the laws of space and time.
