Collective behavior is a term sociologists use to refer to a miscellaneous set of behaviors in which large numbers of people engage. More specifically, collective behavior refers to relatively spontaneous and relatively unstructured behavior by large numbers of individuals acting with or being influenced by other individuals. Relatively spontaneous means that the behavior is somewhat spontaneous but also somewhat planned, while relatively unstructured means that the behavior is somewhat organized and predictable but also somewhat unorganized and unpredictable. As we shall see, some forms of collective behavior are more spontaneous and unstructured than others, and some forms are more likely than others to involve individuals who act together as opposed to merely being influenced by each other. As a whole, though, collective behavior is regarded as less spontaneous and less structured than conventional behavior, such as what happens in a classroom, a workplace, or the other settings for everyday behavior with which we are very familiar.
