The term psychokinesis (from the Greek ψυχή, "psyche", meaning mind, soul, heart, or breath; and κίνησις, "kinesis", meaning motion; literally "movement from the mind"), also known as telekinesis (Greek τῆλε + κίνησις, literally "distant-movement"), sometimes abbreviated PK and TK respectively, is a term coined by publisher Henry Holt to refer to the direct influence of mind on a physical system that cannot be entirely accounted for by the mediation of any known physical energy. Examples of psychokinesis could include distorting or moving an object, and influencing the output of a random number generator. The study of phenomena said to be psychokinetic is part of parapsychology. Some paranormal researchers believe that psychokinesis exists and deserves further study, although the focus of research has shifted away from large-scale phenomena to attempts to influence dice and then to random number generators. There is no convincing scientific evidence that psychokinesis exists. A meta-analysis of 380 studies in 2006 found a "very small" effect which could be explained by publication bias. PK experiments have historically been criticised for lack of proper controls and repeatability.
