Two of the authors participated very intensively in a group therapy situation in which the majority of the patients were schizophrenic. They became aware of certain repeated fluctuations in the level of morale in the group and attempted to discover the origin of these fluctuations. It became clear that certain puzzling fluctuations of mood did not depend upon the amount of participation of the doctors or some increase of acting out in the patients, but were traceable rather to unconscious resentment among the physicians themselves or between some leading figure in the group and the rest of the group. The patients behaved, when they sensed this resentment, as children do eavesdropping on a fight between the parents. If the doctors openly discussed these resentments or used drama therapy, the disturbing atmosphere was quickly resolved.
