This paper explores the influences of a heterogeneous psychoanalytic training setting, such as the Israel Psychoanalytic Institute, on the individual supervision of trainees. While this kind of institute reduces the dangers of submission, uniformity and indoctrination, it creates its own difficulties, “the perils of diversity.” The examples offered include the impact of divergent views of analyzability; aspirations encouraged by certain theoretical models, which may be frustrated in a supervision guided by different views; and controversies regarding psychoanalytic technique, which may confuse a candidate and create inconsistency vis-à-vis the analysand. The open joint exploration of such issues, and of their influence on the supervisory process, is strongly recommended.
