How to Change Your Mind: The New Science of Psychedelics

by Michael Pollan

And yet, successful as the new therapy seemed to be, there was a nagging little problem with the theoretical model on which it was based. When the therapists began to analyze the reports of volunteers, their subjective experiences while on LSD bore little if any resemblance to the horrors of the DTs, or to madness of any kind. To the contrary, their experiences were, for the most part, incredibly—and bafflingly—positive. When Osmond and Hoffer began to catalog their volunteers’ session reports, “psychotic changes”—hallucinations, paranoia, anxiety—sometimes occurred, but there were also descriptions of, say, “a transcendental feeling of being united with the world,” one of the most common feelings reported. Rather than madness, most volunteers described sensations such as a new ability “to see oneself objectively”; “enhancement in the sensory fields”; profound new understandings “in the field of philosophy or religion”; and “increased sensitivity to the feelings of others.”fn3 In spite of the powerful expectancy effect, symptoms that looked nothing like those of insanity were busting through the researchers’ preconceptions.
