In his paper, Freud referred to the contagious and regressive nature of groups described by LeBon and McDougall, but he added the dimension of intrapsychic cathectic shifts that could occur in groups. Freud described the similarity of such groups as the Catholic Church and the army with the hypnotic situation. In all of these situations, there is a leader and one or more followers. The follower obeys the leader and gives up his own superego and ego ideal as he identifies with the leader's superego.
