" The individual is considered part of the mass and included in it (and so far as possible systematically integrated into it) because
in that way his psychic defenses are weakened, his reactions are easier to provoke, and the propagandist profits from the process of
diffusion of emotions through the ma*s and, at the same time, from the pressures felt by an individual when in a group. Emotionalism, impulsiveness, excess, etc. — all these characteristics of the individual caught up in a mass are well known and very helpful to propaganda. Therefore, the individual must never be considered as being alone; the listener to a radio broadcast, though actually alone, is nevertheless part of a large group, and he is aware of it. "

― Jacques Ellul , Propaganda: The Formation of Men's Attitudes
