Theories Developed To Explain Crowd Behavior
Social scientists have developed theories to explain crowd behavior.
- Contagion Theory - the Contagion Theory was formulated by Gustave Le Bon. According to him, crowds exert a hypnotic influence over their members. Shielded by their anonymity, large numbers of people abandon personal responsibility and surrender to the contagious emotions of the crowd. A crowd thus assumes a life of its own, stirring up emotions, and driving people toward irrational, even violent action. Le Bon's Theory, although one of the earliest explanations of crowd behavior, is still used by many people. However, critics argue that the "collective mind" has not been documented by systematic studies. Furthermore, although collective behavior may involve strong emotions, such feelings are not necessarily irrational.
- Convergence Theory - whereas the Contagion Theory states that crowds cause people to act in a certain way, Convergence theory states that people who want to act in a certain way come together to form crowds. It asserts that people with similar attributes find other like-minded persons with whom they can release underlying tendencies. People sometimes do things in a crowd that they would not have the courage to do alone because crowds can diffuse responsibility. Crowds, in addition, can intensify a sentiment simply by creating a critical mass of like-minded people.
- Emergent-Norm Theory - according to Ralph Turner and Lewis Killian, crowds begin as collectivities composed of people with mixed interests and motives. Especially in the case of less stable crowds—expressive, acting and protest crowds—norms may be vague and changing, as when one person decides to break the glass windows of a store and others join in and begin looting merchandise. In short, people in crowds make their own rules as they act.
- Complex Adaptive Systems theory - Dutch scholar Jaap van Ginneken claims that contagion, convergence and emergent norms are just instances of the synergy, emergence and autopoiesis or self-creation of patterns and new entities typical for the newly discovered meta-category of complex adaptive systems. This also helps explain the key role of salient details and path-dependence in rapid shifts.
Decision-making plays a major role in crowd behavior, although casual observes of the crowd may not realize it. In emergent-norm theory, people in a crowd take on different roles: some step forward as leaders, others become followers, inactive bystanders, or even opponents.

“Generalisation is necessary to the advancement of knowledge; but particularly is indispensable to the creations of the imagination. In proportion as men know more and think more they look less at individuals and more at classes. They therefore make better theories and worse poems.”
—Thomas Babington Macaulay (1800–1859)
“They are not callow like the young of most birds, but more perfectly developed and precocious even than chickens. The remarkably adult yet innocent expression of their open and serene eyes is very memorable. All intelligence seems reflected in them. They suggest not merely the purity of infancy, but a wisdom clarified by experience. Such an eye was not born when the bird was, but is coeval with the sky it reflects. The woods do not yield another such a gem.”
—Henry David Thoreau (1817–1862)
“Wags try to invent new stories to tell about the legislature, and end by telling the old one about the senator who explained his unaccustomed possession of a large roll of bills by saying that someone pushed it over the transom while he slept. The expression “It came over the transom,” to explain any unusual good fortune, is part of local folklore.”
—For the State of Montana, U.S. public relief program (1935-1943)
“Let him read what is proper to him, and not waste his memory on a crowd of mediocrities.”
—Ralph Waldo Emerson (1803–1882)
“The inability to control our children’s behavior feels the same as not being able to control it in ourselves. And the fact is that primitive behavior in children does unleash primitive behavior in mothers. That’s what frightens mothers most. For young children, even when out of control, do not have the power to destroy their mothers, but mothers who are out of control feel that they may destroy their children.”
—Elaine Heffner (20th century)
