consistent missing

in parapsychology experiments using Zener cards or similar targets, the phenomenon in which a participant’s “calls,” or guesses, are consistently wrong or significantly below chance expectations. Some people attribute such systematic failure to processing error or a conscious or nonconscious reluctance to confirm psychic ability. See also psi-missing.
