Theories
of Crowd
Behavior
Sociologists seek to understand why people
behave in certain ways when they are a
part of a larger crowd
Comparisons
Contagion and Emergent Norm theories view behaviors as a
response to those around them, whereas Convergence theory
believes that crowds form as a result of seeking out like-minded people
Convergence Theory
In Contagion theory, people
participate in the crowd behavior based
on an emotional response
In Emergent Norm theory, people
participate in the crowd behavior
based on a rational response
Definition
Crowds are formed by people who deliberately
congregate with like-minded others
Focused on the desire of the people within
the crowd to come together based on a
common interest
Emergent Norm
Theory
Definition
Norms develop within a crowd to guide the member's behavior
Within crowds, rules develop (emergent norms)
People within the crowd are present for
various reasons, so they don't
all behave in the same way
(different than Contagion Theory)
Three of the most common theories are...
Contagion Theory
Definition
Members of a crowd stimulate each other to higher and higher levels of emotion and irrational behavior
As emotions within the crowd intensify, people
will temporarily lose their individuality
to the "will" of the crowd
(Deindividualism)
