رفتار جمعی رفتاری است عاطفی که بر اثر وضع یا حادثهای از شخص یا اشخاصی سر میزند و بر اثر واگیری اجتماعی به دیگران منتقل میشود و در نتیجه گروه کمابیش متجانسی به وجود میآید.
شکل این انتقال و ارتباط، ممکن است یک مکالمه یا یک ارتباط یکسویه باشد. به همین ترتیب، شیوه بسیج مردم برای کنش نیز یکسان نیست. یک مورد، ممکن است از سوی کنشگری آغاز شود؛ که صرفاً نمونهای را بهوجود میآورد و قصد ندارد گروهی را بهسوی کنشی، رهبری کند و ممکن است از سوی رهبری آغاز شود که بهصورت خودجوش سر برآورده است؛ یا ممکن است از سوی سازمان توطئهگری طراحی شده باشد. شکل ارتباط و تعامل در تعیین زمانبندی، محتوا، اندازه و گسترهٔ یک مورد رفتار جمعی بسیار حائز اهمیت است.
The expression collective behavior was first used by Franklin Henry Giddings (1908) and employed later by Robert E. Park and Burgess (1921), Herbert Blumer (1939), Ralph Turner and Lewis Killian (1957), and Neil Smelser (1962) to refer to social processes and events which do not reflect existing social structure (laws, conventions, and institutions), but which emerge in a "spontaneous" way. Use of the term has been expanded to include reference to cells, social animals like birds and fish, and insects including ants (Gordon 2014). Collective behavior takes many forms but generally violates societal norms (Miller 2000; Locher 2002). Collective behavior can be tremendously destructive, as with riots or mob violence, silly, as with fads, or anywhere in between. Collective behavior is always driven by group dynamics, encouraging people to engage in acts they might consider unthinkable under typical social circumstances (Locher 2002).
Defining the field
Turner and Killian (1957) were the first sociologists to back their theoretical propositions with visual evidence in the form of photographs and motion pictures of collective behavior in action. Prior to that sociologists relied heavily upon eyewitness accounts, which turned out to be far less reliable than one would hope.
Turner and Killian's approach is based largely upon the arguments of Blumer, who argued that social "forces" are not really forces. The actor is active: He creates an interpretation of the acts of others, and acts on the basis of this interpretation.
Here are some instances of collective behavior: the Los Angeles riot of 1992, the hula-hoop fad of 1958, the stock market crashes of 1929, and the "phantom gasser" episodes in Virginia in 1933–34 and Mattoon, IL in 1944 (Locher 2002; Miller 2000). The claim that such diverse episodes all belong to a single field of inquiry is a theoretical assertion, and not all sociologists would agree with it. But Blumer and Neil Smelser did agree, as did others, indicating that the formulation has satisfied some leading sociological thinkers.
Although there are several other schema that may be used to classify forms of collective behavior the following four categories from Blumer (1939) are generally considered useful by most sociologists.
Scholars differ about what classes of social events fall under the rubric of collective behavior. In fact, the only class of events which all authors include is crowds. Clark McPhail is one of those who treats crowds and collective behavior as synonyms. Although some consider McPhail's work (McPhail 1991) overly simplistic (Locher 2002), his important contribution is to have gone beyond the speculations of others to carry out pioneering empirical studies of crowds. He finds them to form an elaborate set of types.
The classic treatment of crowds is Gustave LeBon, The Crowd: A Study of the Popular Mind (LeBon 1896), in which the author interpreted the crowds of the French Revolution as irrational reversions to animal emotion, and inferred from this that such reversion is characteristic of crowds in general. LeBon believed that crowds somehow induced people to lose their ability to think rationally and to somehow recover this ability once they had left the crowd. He speculated, but could not explain how this might occur. Freud expressed a similar view in Group Psychology and the Analysis of the Ego (1922). Such authors have thought that their ideas were confirmed by various kinds of crowds, one of these being the economic bubble. In Holland, during the tulip mania (1637), the prices of tulip bulbs rose to astronomical heights. An array of such crazes and other historical oddities is narrated in Charles MacKay's Extraordinary Popular Delusions and the Madness of Crowds (MacKay 1841).
At the University of Chicago, Robert Park and Herbert Blumer agreed with the speculations of LeBon and other that crowds are indeed emotional. But to them a crowd is capable of any emotion, not only the negative ones of anger and fear.
A number of authors modify the common-sense notion of the crowd to include episodes during which the participants are not assembled in one place but are dispersed over a large area. Turner and Killian refer to such episodes as diffuse crowds, examples being Billy Graham's revivals, panics about sexual perils, witch hunts and Red scares. Their expanded definition of the crowd is justified if propositions which hold true among compact crowds do so for diffuse crowds as well.
Some psychologists have claimed that there are three fundamental human emotions: fear, joy, and anger. Neil Smelser, John Lofland, and others have proposed three corresponding forms of the crowd: the panic (an expression of fear), the craze (an expression of joy), and the hostile outburst (an expression of anger). Each of the three emotions can characterize either a compact or a diffuse crowd, the result being a scheme of six types of crowds. Lofland has offered the most explicit discussion of these types.
Boom distinguishes the crowd, which expresses a common emotion, from a public, which discusses a single issue. Thus, a public is not equivalent to all of the members of a society. Obviously, this is not the usual use of the word, "public." To Park and Blumer, there are as many publics as there are issues. A public comes into being when discussion of an issue begins, and ceases to be when it reaches a decision on it.
To the crowd and the public Blumer adds a third form of collective behavior, the mass. It differs from both the crowd and the public in that it is defined not by a form of interaction but by the efforts of those who use the mass media to address an audience. The first mass medium was printing.
We change intellectual gears when we confront Blumer's final form of collective behavior, the social movement. He identifies several types of these, among which are active social movements such as the French Revolution and expressive ones such as Alcoholics Anonymous. An active movement tries to change society; an expressive one tries to change its own members.
The social movement is the form of collective behavior which satisfies least well the first definition of it which was offered at the beginning of this article. These episodes are less fluid than the other forms, and do not change as often as other forms do. Furthermore, as can be seen in the history of the labor movement and many religious sects, a social movement may begin as collective behavior but over time become firmly established as a social institution.
For this reason, social movements are often considered a separate field of sociology. The books and articles about them are far more numerous than the sum of studies of all the other forms of collective behavior put together. Social movements are considered in many Wikipedia articles, and an article on the field of social movements as a whole would be much longer than this essay.
The study of collective behavior spun its wheels for many years, but began to make progress with the appearance of Turner and Killian's "Collective Behavior" (1957) and Smelser's Theory of Collective Behavior (1962). Both books pushed the topic of collective behavior back into the consciousness of American sociologists and both theories contributed immensely to our understanding of collective behavior (Locher 2002; Miller 2000). Social disturbances in the U. S. and elsewhere in the late '60s and early '70s inspired another surge of interest in crowds and social movements. These studies presented a number of challenges to the armchair sociology of earlier students of collective behavior.
