 * George P. Hansen, "Deception by Subjects in Psi Research" (tricksterbook.com) &mdash; "The issue of subject deception must be considered when evaluating most parapsychological studies; however, in certain research programs, attempted trickery is virtually certain, whereas in others it is unthinkable. When evaluating a report, a reader must consider the likelihood that deception may have been attempted, along with the effect this might have on the legitimacy of conclusions."
