A Study of Encounter Group Casualties

Irvin D. Yalom and Morton A. Lieberman · 1971

Of 170 students who finished a 30-hour encounter group, 16 were left with lasting harm. Harm clustered under forceful, charismatic leaders who pressed individuals hard instead of working with the group.

Stanford undergraduates signed up for a course and were assigned to one of 18 groups. Each followed one of ten approaches, among them T-groups, Gestalt, psychodrama, transactional analysis and Synanon; one approach replaced the leader with tape-recorded instructions. The researchers counted a casualty when a student came away seriously and lastingly worse off because of the group. The full study appeared as Encounter Groups: First Facts (Lieberman, Yalom & Miles, 1973).

Two findings matter for Circling. The label a leader worked under said little about how they led: Yalom later noted that the two Gestalt leaders were no more alike in practice than any other pair. And the leaders were poor judges of who had been hurt; the other members judged it best.

What it doesn’t show

1960s groups with charismatic leaders, not Circling. A critic argued that the comparison with students outside the groups used a different measure, so how much extra risk the groups carried is disputed. Lieberman, Yalom and Miles (1972) report the same study’s wider outcomes. The students had asked for an encounter-group experience.

Summary based on the abstract and on Yalom’s later account of the study.
