In the mid-70’s there was a shift in view surrounding psi phenomena due to the dismantlement of the classical view (classical physics) of psi because of quantum mechanics (quantum physics).
This new view of psi proposed greater importance to psychokinesis, suggesting it to be a “fundamental” or “primary” psi process that could subsume extrasensory perception, rendering extrasensory perception an assumed direct result of psychokinetic functions (i.e. the movement of information e.g. “thoughts” or packets of information).
I postulate that thought, despite the current incapability of bringing a thought “to rest,” which is required to submit a single thought to examination, does have measurable mass as thought is capable of moving in waves in which implies mass. The motion of implied mass therefore suggests psychokinesis as a primary psi process.
Such a shift in the view of psi also changed the view of psychokinesis from a psychic mechanism (e.g. a psychic lever) to a force-like function, and then to a view of psychokinesis as the ability to shift probabilities of events, to bias probability distributions.
