ABSTRACT
The aspect of the personality engrossed in group processes is the ego. To the convinced Freudian, therefore, group psychology is simply applied ego psychology. Of course, it is more than that. We knew this 40 years ago while I was taking my doctorate in social psychology among the followers of Kurt Lewin (1951), the founder of the field called group dynamics (Cartwright and Zander 1953). One cannot simply reduce all group regularities to the principles encountered in ego psychology.
