Independence of distance and barriers. A repeatable feature of psi is that it is unaffected by distance from the acting mind or physical barriers around it. Independence of complexity. A repeatable feature of telekinesis is that its rate of success is unaffected by the complexity of the target. Independence of time.
Telekinesis can affect physical events that nominally occurred in the past.
Telecognition is able to locate targets that are defined by abstract concepts. For example, a specified side of one page of a magazine. Telecognition is able to find targets given non-unique semantic characteristics but a unique intended reference. In the Berkeleian model of psi, there is no distance. There is no space.
