Societies occasionally experience a phenomenon in which a group of people begin to act in unpredicted ways. This is referred to as collective behavior, “the relatively spontaneous and unstructured behavior of a group of people who are reacting to a common influence in an ambiguous situation” (Schaefer, 2018). 

Crowds, actions of disaster victims, and rumors are considered some forms of collective behavior.
