Psychic Four was very motherly, constantly calling me "darling" and telling me how sorry she was for my loss. Her method of Emily-contact was a mix of prayer and coffee-dregs reading. She made me a small cup of Turkish coffee and when I finished the liquid, she placed the saucer on top of the cup, had me hold it with both hands while moving my arms in a circle three times and then flip the cup and saucer over and put it on the table. She put a blue glass cube with white circles on all six sides on top of the overturned cup and had me to put my finger on the cube and make a wish. I did, and she asked me for the photo. I handed her my phone. She put a small statue of a Turkish philosopher and an angel snow globe in front of me and told me to hold on to both and praying while she turned on her laptop and started playing weird reverb-heavy New Age music featuring a man and woman speaking about being intoxicated on love (not Beyonce style, unfortunately). She was going to ask Emily to make herself known to me.
In 1966 the son of Bishop Pike committed suicide. After his death, Pike contacted the British medium Ena Twigg for a series of séances and she claimed to have communicated with his son. Although Twigg denied formerly knowing anything about Pike and his son, the magician John Booth discovered that Twigg had already known information about the Pike family before the séances. Twigg had belonged to the same denomination of Bishop Pike, he had preached at a cathedral in Kent and she had known information about him and his deceased son from newspapers.
Cold reading also explains why psychics have consistently failed scientific tests of their powers. By isolating them from their clients, psychics are unable to pick up information from the way those clients dress or behave. By presenting all of the volunteers involved in the test with all of the readings, they are prevented from attributing meaning to their own reading, and therefore can't identify it from readings made for others. As a result, the type of highly successful hit rate that psychics enjoy on a daily basis comes crashing down and the truth emerges – their success depends on a fascinating application of psychology and not the existence of paranormal abilities.
In 1880 the American stage mentalist Washington Irving Bishop published a book revealing how mediums would use secret codes as the trick for their clairvoyant readings. The Seybert Commission was a group of faculty at the University of Pennsylvania who in 1884–1887 exposed fraudulent mediums such as Pierre L. O. A. Keeler and Henry Slade. The Fox sisters confessed to fraud in 1888. Margaret Fox revealed that she and her sister had produced the "spirit" rappings by cracking their toe joints.
