Pahnke’s “Good Friday Experiment”: A Long-Term Follow-Up and Methodological Critique
In 1991, Rick Doblin published a long-term follow-up to Walter Pahnke’s landmark 1962 “Good Friday Experiment,” in which psilocybin was administered to divinity students in a religious setting. Doblin’s study, conducted 24 to 27 years after the original experiment, re-interviewed the subjects, re-administered the follow-up questionnaire, and offered a methodological critique of Pahnke’s original design. The paper was published in The Journal of Transpersonal Psychology, Vol. 23, No. 1.
