Gertrude Schmeidler named an effect in studies of this phenomenon the “sheep-goat effect.” Ray Hyman argued that statistical flaws ruined Charles Honorton’s attempts to use a kind of mild sensory deprivation called ganzfeld (“GAHNTS-fehld”) experiments to measure this phenomenon. (15[1])Daryl Bem’s studies of this phenomenon helped spur social psychology’s replication crisis. J.B. Rhine co-created a deck of cards with a circle, a plus sign, wavy lines, a star, and a square to test for this phenomenon, although (*) “leakage” may have occurred in those experiments. The Zener (“ZEE-ner”) cards test this phenomenon, which is the most common form of psi (“sigh”) studied by parapsychologists. For 10 points, name this pseudoscientific phenomenon, in which people allegedly gain information without using any of their physical abilities. ■END■ (10[1])
