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.[186] Schwartz claimed his experiments were indicative of survival, but do not yet provide conclusive proof.[187][188] The experiments described by Schwartz have received criticism from the scientific community for being inadequately designed and using poor controls.[189][190]
Telephone readings are live readings where both psychic and client hear each other by connecting via premium rate telephone line. In the last years, with restrictions on premium rate numbers, more common are pre-paid callbacks, in which case client leaves his/her credit card details over the phone to an operator, after which gets a call on a specified phone number. Telephone readings became most popular with the growth of live advice TV shows as main means of advertising, and is commonly used by companies rather than individual psychics, due to high setup costs.[citation needed]
The Polish medium Stanisława Tomczyk's levitation of a glass beaker was exposed and replicated in 1910 by the magician William S. Marriott by means of a hidden thread.[114] The Italian medium Lucia Sordi was exposed in 1911, she was bound to a chair by psychical researchers but would free herself during her séances. The tricks of another Italian medium Linda Gazzera were revealed in the same year, she would release her hands and feet from control in her séances and use them. Gazzera would not permit anyone to search her before a séance sitting, as she concealed muslin and other objects in her hair.[115]

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.[50]
In 1918, Joseph Jastrow wrote about the tricks of Eusapia Palladino who was an expert at freeing her hands and feet from the control in the séance room.[118] In the séance room Palladino would move curtains from a distance by releasing a jet of air from a rubber bulb that she had in her hand.[119] According to the psychical researcher Harry Price "Her tricks were usually childish: long hairs attached to small objects in order to produce 'telekinetic movements'; the gradual substitution of one hand for two when being controlled by sitters; the production of 'phenomena' with a foot which had been surreptitiously removed from its shoe and so on."[120]
In September 1878 the British medium Charles Williams and his fellow-medium at the time, A. Rita, were detected in trickery at Amsterdam. During the séance a materialized spirit was seized and found to be Rita and a bottle of phosphorus oil, muslin and a false beard were found amongst the two mediums.[82] In 1882 C. E. Wood was exposed in a séance in Peterborough. Her Indian spirit control "Pocka" was found to be the medium on her knees, covered in muslin.[83]
