The discrepancy between these results and those obtained by Rhine is due either to uncontrollable factors in experimental procedure or to the difference in the subjects.” Four other psychological departments failed to replicate Rhine’s results. Cox concluded “There is no evidence of extrasensory perception either in the ‘average man’ or of the group investigated or in any particular individual of that group. Cox (1936) from Princeton University with 132 subjects produced 25,064 trials in a playing card ESP experiment. A number of psychological departments attempted to repeat Rhine’s experiments with failure.
The parapsychology experiments at Duke evoked criticism from academics and others who challenged the concepts and evidence of ESP. Later he used dice to test for psychokinesis. To try to observe precognition, the order of the cards is determined after the guesses are made. To try to observe clairvoyance, the pack of cards is hidden from everyone while the receiver guesses.

In a telepathy experiment, the “sender” looks at a series of cards while the “receiver” guesses the symbols. They bear the symbols circle, square, wavy lines, cross, and star there are five cards of each in a pack of 25. A simple set of cards was developed, originally called Zener cards – now called ESP cards. Rhine worked largely in the laboratory, carefully defining terms such as ESP and psi and designing experiments to test them. While Louisa Rhine concentrated on collecting accounts of spontaneous cases, J. Rhine conducted investigation into extrasensory perception. In the 1930s, at Duke University in North Carolina, J. Zener cards were first used in the 1930s for experimental research into ESP. The scientific community rejects ESP due to the absence of an evidence base, the lack of a theory which would explain ESP, and the lack of experimental techniques which can provide reliably positive results and considers ESP to be pseudoscience. Parapsychology has been criticized for continuing investigation despite being unable to provide convincing evidence for the existence of any psychic phenomena after more than a century of research. Parapsychology is the study of paranormal psychic phenomena, including ESP. Rhine to denote psychic abilities such as intuition, telepathy, psychometry, clairaudience, and clairvoyance, and their trans-temporal operation as precognition or retrocognition. The term was adopted by Duke University psychologist J. Extrasensory perception, ESP or Esper, also called sixth sense or second sight, includes claimed reception of information not gained through the recognized physical senses but sensed with the mind.
