Group Psychology and the Analysis of the Ego

by Sigmund Freud

The most careful investigations seem to prove that an individual immersed for some length of time in a group in action soon finds himself—either in consequence of the magnetic influence given out by the group, or from some other cause of which we are ignorant—in a special state, which much resembles the state of fascination in which the hypnotised individual finds himself in the hands of the hypnotiser.... The conscious personality has entirely vanished; will and discernment are lost. All feelings and thoughts are bent in the direction determined by the hypnotiser. 'Such also is approximately the state of the individual forming part of a psychological group. He is no longer conscious of his acts. In his case, as in the case of the hypnotised subject, at the same time that certain faculties are destroyed, others may be brought to a high degree of exaltation. Under the influence of a suggestion, he will undertake the accomplishment of certain acts with irresistible impetuosity. This impetuosity is the more irresistible in the case of groups than in that of the hypnotised subject, from the fact that, the suggestion being the same for all the individuals of the group, it gains in strength by reciprocity.'
