The term was coined by classics scholar and psychologist Frederic William Henry Myers in 1882. Sigmund Freud did experiments with his daughter Anna where he attempted to communicate with her telepathically. In 1930 Upton Sinclair wrote a book about his experiments with his wife in telepathic communication entitled Mental Radio.
Professor Hans Eysenck of London University's Institute of Psychiatry stated "Unless there is a gigantic conspiracy involving some thirty university departments all over the world, and several hundred highly respected scientists in various fields, many of them originally skeptical to the claims of the psychical researchers, the only conclusion that the unbiased observer can come to is that there does exist a small number of people who obtain knowledge existing in other people's minds, or in the outer world, by means as yet unknown to science".
A panel commissioned by the United States National Research Council to study paranormal claims concluded that "despite a 130-year record of scientiﬁc research on such matters, our committee could ﬁnd no scientiﬁc justiﬁcation for the existence of phenomena such as extrasensory perception, mental telepathy or 'mind over matter' exercises... Evaluation of a large body of the best available evidence simply does not support the contention that these phenomena exist." The scientific community considers parapsychology a pseudoscience. There is no known mechanism for telepathy. Philosopher and physicist Mario Bunge has written that telepathy would contradict laws of science and the claim that "signals can be transmitted across space without fading with distance is inconsistent with physics".
- taken from the Greek τηλε, tele meaning "distant" and πάθεια, patheia meaning "to be affected by". It follows the model of sympathy and empathy.

PK action-at-a-distance would presumably employ an action-at-a-distance force that is as yet unknown to science... Similarly, there is no known sense (stimulation and receptor) by which thoughts could travel from one person to another by which the mind could project itself elsewhere in the present, future, or past."

- "Precognition violates the principle of antecedence ("causality"), according to which the effect does not happen before the cause. Psychokinesis violates the principle of conservation of energy as well as the postulate that mind cannot act directly on matter. (If it did no experimenter could trust his own readings of his instruments.) Telepathy and precognition are incompatible with the epistemological principle according to which the gaining of factual knowledge requires sense perception at some point."
- "Parapsychology makes no use of any knowledge gained in other fields, such as physics and physiological psychology. Moreover, its hypotheses are inconsistent with some basic assumptions of factual science. In particular, the very idea of a disembodied mental entity is incompatible with physiological psychology; and the claim that signals can be transmitted across space without fading with distance is inconsistent with physics."
