The importance of transference and countertransference is becoming increasingly evident in all kinds of human relationships, including international relations. Group therapy facilitates the demonstration of these factors, for transferences are more multiple, labile, fragmented, and variable than those seen in individual treatment, while the therapist's actions may be caused as much by his need to control the anxiety stemming from his countertransference as by the patient's real need. Hard as it may be for him to do so, the group psychotherapist can often greatly benefit by accepting the interpretations of the group members made upon himself.
