Abstract

Argues that psi as anomaly has been established because conventional science has yet to provide adequate explanations for ostensibly paranormal experiences. However, psi as paranormal process has not been established because no particular paranormal theory has yet achieved adequate empirical verification. Verification of psi in the latter sense requires a shift from a negative research approach, in which the top priority is elimination of conventional hypotheses, to a positive approach, in which the top priorities are to get the anomalies to occur and to uncover their correlates. Nonetheless, experimental psi research can point to important accomplishments, which include demonstrating that the anomalies occur in laboratories, reducing the plausibility of conventional hypotheses, uncovering quasi-lawful correlates, and generating testable models.
