Psychokinesis

Psychokinesis (Greek ψυχή κίνησις, "mind movement"), or telekinesis, is an alleged psychic ability allowing a person to influence a physical system without physical interaction. Psychokinesis and telekinesis are sometimes abbreviated as PK and TK respectively. Examples of psychokinesis could include moving an object, levitating and teleporting.

The study of supposed psychokinetic phenomena is part of parapsychology. Some parapsychologists claim psychokinesis exists and deserves further study. Current research has shifted focus away from large-scale phenomena to attempts to influence dice and random number generators.

There is no scientific evidence that psychokinesis or telekinesis are real phenomena. PK experiments have historically been criticized for lack of proper controls and repeatability. Furthermore, some experiments have created illusions of PK where none exists, and these illusions depend to an extent on the subject's prior belief in PK.
