The trance medium Leonora Piper was investigated by psychical researchers and psychologists in the late 19th and early 20th century. In an experiment to test if Piper's "spirit" controls were purely fictitious the psychologist G. Stanley Hall invented a niece called Bessie Beals and asked Piper's 'control' to get in touch with it. Bessie appeared, answered questions and accepted Hall as her uncle. The psychologist Joseph Jastrow wrote that Piper pretended to be controlled by spirits and fell into simple and logical traps from her comments. Science writer Martin Gardner concluded Piper was a cold reader that would "fish" for information from her séance sitters. The physiologist Ivor Lloyd Tuckett who examined Piper's mediumship in detail wrote it could be explained by "muscle-reading, fishing, guessing, hints obtained in the sitting, knowledge surreptitiously obtained, knowledge acquired in the interval between sittings and lastly, facts already within Mrs. Piper's knowledge."
Another important distinction is that while psychic readings often focus on predicting future events, mediums primarily tune into past and present issues. It's my opinion that predicting the future, while sometimes helpful, runs the risk of disempowering people. Always remember that you do have a say in how your future unfolds. Despite what any psychic or medium may "see" in your future, it is important to remember you were given the gift of free will when you came into this world, and at any moment in time you can absolutely redirect your course and create the life you want by changing your thoughts and actions. Psychic information is often just insight into what potentially could happen based on the road you are currently traveling—and it should be used only as a guideline to help you make the best choices for yourself.
The VERITAS Research Program of the Laboratory for Advances in Consciousness and Health in the Department of Psychology at the University of Arizona, run by the parapsychologist Gary Schwartz, was created primarily to test the hypothesis that the consciousness (or identity) of a person survives physical death. Schwartz claimed his experiments were indicative of survival, but do not yet provide conclusive proof. The experiments described by Schwartz have received criticism from the scientific community for being inadequately designed and using poor controls.

"Mental mediumship" is communication of spirits with a medium by telepathy. The medium mentally "hears" (clairaudience), "sees" (clairvoyance), and/or feels (clairsentience) messages from spirits. Directly or with the help of a spirit guide, the medium passes the information on to the message's recipient(s). When a medium is doing a "reading" for a particular person, that person is known as the "sitter".
Surprisingly, tarot is a relatively modern craft. Though tarot decks date back to the 1400s, pictorial cards were originally used for games rather than prediction. Cartomancy, or fortune-telling through the use of playing cards, actually wasn't developed until 1785, when French occultist Jean-Baptiste Alliette — known by his pseudonym, Etteilla, the inversion of his surname — created comprehensive links between illustrated cards, astrology, and ancient Egyptian lore.
The British direct-voice medium Frederick Tansley Munnings was exposed as a fraud when one of his séance sitters turned the lights on which revealed him to be holding a trumpet by means of a telescopic extension piece and using an angle piece to change the auditory effect of his voice. Richard Hodgson held six sittings with the medium Rosina Thompson and came to the conclusion she was a fraud as he discovered Thompson had access to documents and information about her séance sitters.
Between 8 November and 31 December 1920 Gustav Geley of the Institute Metapsychique International attended fourteen séances with the medium Franek Kluski in Paris. A bowl of hot paraffin was placed in the room and according to Kluski spirits dipped their limbs into the paraffin and then into a bath of water to materialize. Three other series of séances were held in Warsaw in Kluski's own apartment, these took place over a period of three years. Kluski was not searched in any of the séances. Photographs of the molds were obtained during the four series of experiments and were published by Geley in 1924. Harry Houdini replicated the Kluski materialization moulds by using his hands and a bowl of hot paraffin.
"Have a little fun with friends," she told INSIDER. "Before going out one night, pull three cards with the intention of the cards giving you some forewarning about the evening. Let it be fun and easy and involve everyone! You can even ask, 'what happens if we go to this spot or this one?' Let the cards decide your night and see if they gave good advice!"
