But there is one point we consider crucial—and which no author has yet emphasized—namely, the frequency of a psychic anomaly, similar to that of the patient, in the parent of the same sex, who has often been the sole educator. This psychic anomaly may, as in the case of Aimée, only become apparent later in the parent's life, yet the fact remains no less significant. Our attention had long been drawn to the frequency of this occurrence. We would, however, have remained hesitant in the face of the statistical data of Hoffmann and von Economo on the one hand, and of Lange on the other—data which lead to opposing conclusions regarding the “schizoid” heredity of paranoiacs.

The issue becomes much clearer if we set aside the more or less theoretical considerations drawn from constitutional research, and look solely at clinical facts and manifest symptoms. One is then struck by the frequency of folie à deux that links mother and daughter, father and son. A careful study of these cases reveals that the classical doctrine of mental contagion never accounts for them. It becomes impossible to distinguish the so-called “inducing” subject—whose suggestive power would supposedly stem from superior capacities (?) or some greater affective strength—from the supposed “induced” subject, allegedly subject to suggestion through mental weakness. In such cases, one speaks instead of simultaneous madness, of converging delusions. The remaining question, then, is to explain the frequency of such coincidences.
