According to Schein, a Crowd Is Merely a Large Group

According to Schein, a crowd is merely a large group.
E. H. Schein helps make the distinction clear:
The size of a group is . . . limited by the possibilities of mutual interaction and mutual awareness. Mere aggregates of people do not fit this definition because they do not interact and do not perceive themselves to be a group even if they are aware of each other as, for instance, a crowd on a street corner watching some event.
