Doubts About the Psychology Game A career in question Leary’s earlier research suggests that conventional psychotherapy may not reliably change outcomes. He arrives at Harvard already skeptical of the field’s methods and institutions. A volatile temperament His charisma and appetite for provocation help him attract students, but they also make colleagues question his scientific judgment before psychedelics enter the story.
The Psilocybin RevelationThe Psilocybin Revelation from "How to Change Your Mind". A Personal Conversion A new view of mind Leary experiences psilocybin in Mexico and returns convinced that consciousness can be systematically expanded.
A Personal Conversion A new view of mind Leary experiences psilocybin in Mexico and returns convinced that consciousness can be systematically expanded. He describes the event as a greater education than years of psychology. Urgency takes hold The experience renews his interest in the mind, but also gives him a prophetic sense of mission. Scientific curiosity begins to share space with evangelism.

Research Becomes a Community A popular project Leary and Richard Alpert establish the Harvard Psilocybin Project and recruit many participants. Naturalistic sessions make the work vivid but methodologically vulnerable. Growing criticism David McClelland and Herbert Kelman raise concerns about controls, supervision, and pressure on students. Leary’s interest in research increasingly competes with his larger cultural ambitions.

Leaving the University Conflict becomes news The Harvard controversy reaches the press, and Leary and Alpert leave the university. Leary declares that the work is too controversial for a university setting. A new role He shifts from psychologist toward public advocate, embracing mass access and social change. The shift makes him influential while alienating researchers who seek institutional protection.
A Legacy of ContradictionA Legacy of Contradiction from "How to Change Your Mind". Influence and Blame Cultural force Leary becomes a symbol of psychedelic counterculture and faces prosecution, imprisonment, escape, and continued publicity.
Influence and Blame Cultural force Leary becomes a symbol of psychedelic counterculture and faces prosecution, imprisonment, escape, and continued publicity. His slogans help bind the drugs to social revolt. Complicated remembrance At the researchers’ reunion, Leary presents himself as playing a necessary role, while others acknowledge the damage his conduct caused. His legacy becomes both obstacle and inheritance for later research.
