Types of crowds
Herbert Blumer-American sociologist whose main scholarly interests were symbolic interactionism
Blumer divided crowds into four categories:
Casual crowds—relatively large gatherings of people who happen to be in the same place at the same time; if they interact at all, it is only briefly
Conventional crowds—people who come together for a scheduled event and thus share a common focus
Expressive crowds—people releasing their pent‑up emotions in conjunction with others who experience similar emotions
3
Types of crowds (cont'd)
Acting crowds—collectivities so intensely focused on a specific purpose or object that they may erupt into violent or destructive behavior. Examples:
A mob—a highly emotional crowd whose members engage in, or are ready to engage in, violence against a specific target which may be a person, a category of people, or physical property
A riot—violent crowd behavior fueled by deep‑seated emotions but not directed at a specific target
A panic—a form of crowd behavior that occurs when a large number of people react with strong emotions and self‑destructive behavior to a real or perceived threat.
4
Types of crowds (cont'd)
To these four types of crowds, Clark McPhail and Ronald T. Wohlstein added protest crowds—crowds that engage in activities intended to achieve specific political goals.
Protest crowds sometimes take the form of civil disobedience— nonviolent action that seeks to change a policy or law by refusing to comply with it.
At the grassroots level, protests often are seen as the only way to call attention to problems or demand social change.

Explanations of Crowd Behavior
According to contagion theory:
People are more likely to engage in antisocial behavior in a crowd because they are anonymous and feel invulnerable.
Gustave Le Bon argued that feelings of fear and hate are contagious in crowds because people experience a decline in personal responsibility.
10
Crowd Theory
According to Robert Park:
Social unrest is transmitted by a process of circular reaction.
The interactive communication between persons in such a way that the discontent of one person is communicated to another who, in turn, reflects the discontent back to the first person.
11
Convergence theory
This focuses on the shared emotions, goals, and beliefs many people bring to crowd behavior.
From this perspective, people with similar attributes find a collectivity of like‑minded persons with whom they can release their underlying personal tendencies.
People may reveal their "true selves" in crowds.

Emergent norm theory
Ralph Turner's and Lewis Killian's emergent norm theory states the following:
Crowds develop their own definition of the situation.
Crowds establish norms for behavior that fit the occasion.
Emergent norms occur when people define a new situation as highly unusual or see a long‑standing situation in a new light.
Emergent norm theory points out that crowds are not irrational.
New norms are developed in a rational way.
New norms are developed to fit the needs of the immediate situation.
