Group Psychology and the Analysis of the Ego

by Sigmund Freud

Let us make the matter clear once again. If a Psychology, concerned with exploring the predispositions, the instincts, the motives and the aims of an individual man down to his actions and his relations with those who are nearest to him, had completely achieved its task, and had cleared up the whole of these matters with their inter-connections, it would then suddenly find itself confronted by a new task which would lie before it unachieved. It would be obliged to explain the surprising fact that under a certain condition this individual whom it had come to understand thought, felt, and acted in quite a different way from what would have been expected. And this condition is his insertion into a collection of people which has acquired the characteristic of a 'psychological group'. What, then, is a 'group'? How does it acquire the capacity for exercising such a decisive influence over the mental life of the individual? And what is the nature of the mental change which it forces upon the individual? It is the task of a theoretical Group Psychology to answer these three questions.
