Biography
Katherine MacLean is a psychologist who trained at Johns Hopkins under Roland Griffiths and Matthew Johnson, contributing to landmark research on psilocybin's effects on personality and openness to experience. Her 2011 study demonstrated that a single high-dose psilocybin session can produce lasting increases in the personality trait of openness — one of the few known ways to produce permanent personality change in healthy adults. MacLean has also worked extensively with meditation retreat settings and the intersection of contemplative practice with psychedelic experience. She is the author of 'Touched with Fire: A Visionary Account of Life with Bipolar Disorder.'
