Abstract

Describes the current crisis of confidence in the results of psi experiments as a problem of poor replicability. The fact that a few experimenters are more successful than others suggests the possibility that the psi measured may be coming from them, rather than from the Ss. Review papers by J. E. Kennedy and J. L. Taddonio (1976) have suggested the possibility of experimenter (E) and observer effects that cannot be explained by R. Rosenthal's (1966) model and may be due to an E's psi ability in combination with or in place of that of his or her Ss. Observational theories that for there to be psi effects, the source of the psi must get feedback, are applied to the problem and are seen as a first step toward a more inclusive model of psi function.
