Telepathy (Greek τηλε, tele meaning "distant" and πάθεια, patheia meaning "to be affected by") describes the purported transfer of information on thoughts or feelings between individuals by means other than the five classical senses (See Psi). The term was coined in 1882 by the classical scholar Fredric W. H. Myers, a founder of the Society for Psychical Research, specifically to replace the earlier expression thought-transference. A person who is able to make use of telepathy is said to be able to read the minds of others. Telepathy, along with psychokinesis forms the main branches of parapsychological research, and many studies seeking to detect and understand telepathy have been done within the field.

Telepathy is a common theme in fiction and science fiction, with many superheroes and supervillains having telepathic abilities. Such abilities include sensing the thoughts of others. Some Transhumanists believe that technologically enabled telepathy, called "techlepathy", will exist in the future of humanity, and seek to develop practical machines for this.

Telepathy in popular culture

Literature

Telepathy is commonly used in fiction, with a number of superheroes and supervillains, as well as figures in many science fiction novels, etc., use telepathy. Notable fictional telepaths include the Jedi in Star Wars. The mechanics of telepathy in fiction vary widely. Some fictional telepaths are limited to receiving only thoughts that are deliberately sent by other telepaths, or even to receiving thoughts from a specific other person. For example, in Robert A. Heinlein's 1956 novel Time for the Stars, certain pairs of twins are able to send telepathic messages to each other. Some telepaths can read the thoughts only of those they touch, such as Vulcans in the Star Trek media franchise. At the opposite end of the spectrum, some telepathic characters continuously sense the thoughts of those around them and may control or dampen this ability only with difficulty, or not at all, such as in Scanners. In such cases,telepathy is often portrayed as a mixed blessing or as a curse.

Some writers view telepathy as the evolutionary destiny of humanity. In Tony Vigorito's novel, Just a Couple of Days, telepathy emerges across the entire human species as a result of the Pied Piper Virus, which inadvertently eliminated humanity's symbolic capacity. In this instance, telepathy is seen as a latent ability that emerges only when the distractions of language are bypassed.

Some fictional telepaths possess mind control abilities, which can include "pushing" thoughts, feelings, or hallucinatory visions into the mind of another person, causing pain, paralysis, or unconsciousness, altering or erasing memories, or completely taking over another person's mind and body (similar to spiritual possession). Examples of this type of telepath include the Carpathians from the novels in the Dark Series, the White Queen from Marvel Comics. Characters with this ability may or may not also have the ability to read thoughts. The Urdu novel "Devta" is based on the character of Farhad Ali Taimur, a telepath and involves in the fight of good and evil. Devta is the longest continuously-published novel in history.

Telepathing - same meaning as to telepath, only different verb tense.

Technological Telepathy is also present in science fiction, typically involving the usage of neural implants of some description. A good example is the Conjoiners in the Revelation Space series by Alastair Reynolds. Conjoiners rely on their technological telepathy (referred to by them as "Transenlightenment") to the extent that they no longer actually speak. Certain Conjoiners are able to read, attack and control the minds of other Conjoiners and machines (though not standard humans) using digital attacks, often having similar effects to other telepaths in fiction.

Technologically enabled telepathy
Converging Technologies, a 2002 report exploring the potential for synergy among nano-, bio-, informational and cognitive technologies (NBIC) for enhancing human performance.

Some people, occasionally referred to by themselves or others as "transhumanists", believe that technologically enabled telepathy, coined "techlepathy","synthetic telepathy",or "psychotronics", will be the inevitable future of humanity. Kevin Warwick of the University of Reading, England is one of the leading proponents of this view and has based all of his recent cybernetics research around developing practical, safe technology for directly connecting human nervous systems together with computers and with each other. He believes techno-enabled telepathy will in the future become the primary form of human communication. He predicts that this will happen by means of the principle of natural selection, through which nearly everyone will have the need for such technology for economic and social reasons.

Telepathy in parapsychology
Main articles: Scientific investigation of telepathy, Parapsychology, and Ganzfeld experiment

Within the field of parapsychology, telepathy is considered to be a form of extra-sensory perception (ESP) or anomalous cognition in which information is transferred through Psi. It is often categorized similarly to precognition and clairvoyance.[6] Various experiments have been used to test for telepathic abilities. Among the most well known are the use of Zener cards and the Ganzfeld experiment.
Zener cards

Zener cards are cards marked with five distinctive symbols. When using them, one individual is designated the "sender" and another the "receiver". The sender must select a random card and visualize the symbol on it, while the receiver must attempt to determine that symbol using Psi. Statistically, the receiver has a 20% chance of randomly guessing the correct symbol, so in order to demonstrate telepathy, they must repeatedly score a success rate that is significantly higher than 20%. If not conducted properly, this method can be vulnerable to sensory leakage and card counting.

When using the Ganzfeld experiment to test for telepathy, one individual is designated the receiver and is placed inside a controlled environment where they are deprived of sensory input, and another is designated the sender and is placed in a separate location. The receiver is then required to receive information from the sender. The exact nature of the information may vary between experiments.

Types of telepathy

Parapsychology describes several different forms of telepathy, including latent telepathy and precognitive telepathy.

Latent Telepathy, formerly known as "deferred telepathy", is described as being the transfer of information, through Psi, with an observable time-lag between transmission and receipt.

Precognitive Telepathy is described as being the transfer of information, through Psi, about the future state of an individual's mind

Emotive Telepathy, also known as remote influence or emotional transfer, is the process of transferring kinesthetic sensations through altered states.

Superconscious Telepathy, involves tapping into the superconscious to access the collective wisdom of the human species for knowledge.
