Research into the long-lasting effects of administering d-lysergic acid diethylamide LSD to normals is discussed. In addition to its use in psychotherapy, there were some reports of experimental subjects who claim lasting beneficial effects attributable to the LSD experience. In particular, two follow-up questionnaire studies indicated that normal subjects frequently claim changes in personality resulting from only one or two administrations of LSD, and these claims were maintained after periods of a year or more. These results are subject to the weaknesses of the questionnaire method but, when considered along with some of the literature on the use of LSD in psychotherapy, they appear to be sufficiently suggestive to warrant more controlled experiments in this area. An experiment is suggested which would attempt to measure any long-lasting changes in attitudes, values, and communicative ability resulting from the administration of LSD. In particular, the measures would concentrate on changes in closed-mindness as reflected by scales of dogmatism, opinionation, and ethnocentricity.
