Getting IT: The Psychology of Est

Getting It: The Psychology of est is a non-fiction book by American psychologist Sheridan Fenwick, first published in 1976, analyzing Werner Erhard's Erhard Seminars Training or est. It is based on Fenwick's own experience of attending a four-day session of the est training, an intensive 60-hour personal development course in the self-help genre. Large groups of up to 250 people took the est training at one time.

In the first section of Fenwick's book, she recounts the est training process and the methods used during the course. Fenwick details the rules or "agreements" laid out by the trainers to the attendees, which include not talking to others or leaving the session to go to the bathroom unless during an announced break period. The second section is analytic: Fenwick analyzes the methods used by the est trainers, evaluates the course's potential effects, and discusses Erhard's background. Fenwick concludes that the program's long-term effects are unknown, and that the est training could harm certain groups of people.

Writing in Library Journal, psychiatrist James Charney describes the book as "the only useful critical look" at the training. Zane Berzins of The New York Times Book Review characterizes the book as a "calm and professionally informed view". Hearings held in 1979 before the United States House of Representatives on a juvenile delinquents program depicted in Scared Straight! cited the book for background on the est training, as did psychologist Gidi Rubinstein in a 2005 study of the Landmark Forum published in the academic journal Psychology and Psychotherapy: Theory, Research and Practice.
