“[When testing psychic abilities of normal people who claimed no psychic powers, J.B Rhine found that] success rate deteriorates if you undertake prolonged experimentation. As with telepathy, clairvoyance and precognition experiments, J.B Rhine observed that this decline effect reflected the subject's loss of interest. [...] And as with other ESP experiments, the degree of belief in your powers can prove significant. Rhine found that sceptics again scored below what you would expect from chance alone.” ParanormalSupernaturalPsychic AbilitiesPsychic PowersEspParapsychologyPsychic AbilityRhinePsychic Power Book:Your Psychic Powers: A Beginner's Guide Source: Your Psychic Powers: A Beginner's Guide
