The Core Definition of Collective Behavior
The concept of Collective Behavior refers to social processes and events that arise spontaneously, operating outside the established framework of existing social norms, conventions, and institutions. Coined initially by Robert E. Park and later formally defined and systematized by Herbert Blumer, this sociological domain focuses on actions that are neither strictly conforming, where actors follow prevailing norms, nor strictly deviant, where actors explicitly violate those norms. Instead, collective actions emerge in situations where established behavioral guidelines are absent, contradictory, or unclear, necessitating the participants to generate new, temporary forms of social order.
The fundamental principle underpinning collective behavior is its fluidity and lack of institutionalization. Unlike highly predictable interactions governed by formal social structure, collective actions represent a dynamic, emergent third category of human activity. While scholars have historically dedicated extensive research to understanding conformity and deviance, the spontaneous and often ephemeral nature of collective processes meant they received comparatively less rigorous attention until the mid-twentieth century. Understanding how large groups act when the rulebook is missing or being rewritten is crucial for interpreting rapid social change, social disturbances, and the formation of new cultural trends.
Historical Foundations and Theoretical Origins
The definitive intellectual foundation for the study of collective behavior was laid by sociologist Herbert Blumer, particularly through his seminal essay, “An Outline of Collective Behavior.” Blumer, working within the Chicago School tradition alongside Robert Park, provided the core delineation of the field, establishing a proto-paradigm that organized diverse spontaneous social episodes—from crowds and panics to social movements—into a coherent area of sociological inquiry. This early work was crucial because it moved the study beyond mere anecdotal description toward a framework suitable for empirical investigation, even though the field itself remained relatively data-scarce for many years.
Early, influential, though often criticized, treatments of one key form of collective behavior—the crowd—date back to the late 19th and early 20th centuries. The classic text here is Gustave Le Bon‘s 1896 work, The Crowd: A Study of the Popular Mind. Le Bon, writing from the perspective of a fearful aristocrat observing the tumults of the French Revolution, characterized crowd behavior as an irrational reversion to primal, animalistic emotion. Sigmund Freud echoed a similar sentiment in Group Psychology and the Analysis of the Ego (1922). However, scholars at the University of Chicago, including Park and Blumer, while agreeing that crowds are highly emotional, offered a more nuanced view, asserting that a crowd is capable of expressing the full spectrum of human emotions, including joy and fear, not just negative ones like anger and irrationality.
Blumer’s Proto-Paradigm: An Interpretive Approach
Blumer’s conceptualization of collective behavior is deeply rooted in his broader interpretive sociology, which offered a radical critique of prevailing sociological schemes. He argued that many theories erroneously treated the social actor as passive, suggesting that individuals were merely controlled by external social forces acting upon them like physical stimuli on an organism. In Blumer’s view, social “forces” are not truly forces in the physical sense. Instead, the actor is fundamentally active: individuals constantly create interpretations of the acts of others and subsequently base their own actions on these interpretations. This emphasis on interpretation and shared meaning is fundamental to understanding how spontaneous collective action takes shape.
Blumer’s theoretical framework functions as a “proto-paradigm,” a concept analogous to Thomas Kuhn’s idea of a paradigm in mature sciences. While sociology lacks the decisive empirical evidence and unified theoretical guidance of a true scientific paradigm, Blumer’s scheme provides a set of core propositions and techniques that both summarize existing knowledge and offer direction for future empirical studies. This framework contrasts sharply with those offered by structural functionalists like Talcott Parsons, positioning collective behavior not as a mere breakdown of the system, but as a critical, interpretive process through which new social meanings and actions emerge.
Primary Forms of Collective Behavior
Blumer identified four fundamental forms of collective behavior, though not all sociologists agree that such disparate phenomena belong to a single field. These forms illustrate the range of spontaneous social interaction, from temporary gatherings to enduring organized efforts.
The Crowd is the only form universally accepted as collective behavior by all scholars. Crowds are characterized by the expression of a common emotion. Scholars like Clark McPhail have moved beyond early speculation to conduct pioneering empirical studies, identifying crowds as complex phenomena forming elaborate sets of types. Furthermore, Turner and Killian expanded the common-sense notion of the compact crowd to include the “diffuse crowd,” where participants are geographically dispersed but unified by a common focus, such as during mass religious revivals or widespread panics about social perils. Sociologists have proposed corresponding forms of crowds based on fundamental emotions: the panic (fear), the craze (joy, often seen in economic bubbles like the 1637 tulip mania), and the hostile outburst (anger).
The Public is distinguished from the crowd because it engages in the discussion of a single, specific issue, rather than expressing a shared emotion. For Park and Blumer, a public is not synonymous with the entire society; rather, publics emerge when a discussion begins and cease to exist when a decision is reached on the issue at hand. Blumer was highly critical of academic practices like sample surveys and public opinion polling, arguing that they falsely assume each participant has equal weight. He emphasized that participants enter discussions with differing degrees of engagement and influence, pointing out that in the real-world resolution of an issue, a highly influential figure, such as an archbishop, carries significantly more weight than a less influential citizen.
The Mass constitutes a third form, defined not by interaction but by the efforts of those using mass media to address an audience. Starting with printing and accelerating with modern technologies, the impact of the mass media has grown exponentially. The mass acts when its members choose among a set of options offered by the media, such as selecting a brand of consumer product or choosing a television program. This collective choice can have unexpected societal impacts; for instance, widespread viewing of a popular show might lead viewers to use facilities during commercial breaks, creating a surge in demand for municipal sewage disposal. However, some scholars, following Max Weber, suggest the mass is best understood as an “ideal type,” recognizing that consumers rarely act in complete isolation and often discuss their choices.
Finally, the Social Movement represents a significant shift in intellectual gears. Unlike the other fluid forms, social movements are less spontaneous and more organized. Blumer distinguished between active social movements, which strive to change society (e.g., the French Revolution), and expressive social movements, which aim to change their own members (e.g., Alcoholics Anonymous). Because social movements often begin as collective behavior but can evolve into firmly established social institutions, they satisfy the core definition of collective behavior least well. Consequently, the study of social movements has often been treated as a separate, highly detailed field of sociology, garnering far more research attention than the study of crowds or masses combined.
Real-World Examples of Collective Action
The scope of collective behavior is vast and encompasses seemingly disparate events, demonstrating the theoretical assertion that these phenomena share a common underlying mechanism of spontaneity and non-institutionalized action. Examples range from subtle shifts in linguistic trends, such as the frequent and widespread use of the word “like” among adolescent girls, to major political and economic shifts.
A clear example of collective debate and decision-making by a public involves international policy, such as the national discussions and disagreements in countries like Canada and the United States regarding whether to ratify environmental agreements like the Kyoto protocols. Similarly, technological shifts illustrate collective action in the mass: the rapid change from 50% market saturation by older software like WordPerfect 5.1 for DOS to the even more widespread collective adoption and use of Microsoft Word represents a mass choice among consumer options, driven by factors beyond formal mandates. Furthermore, organized, expressive efforts, such as the Esperanto movement to establish a neutral international language, also fall under this broad umbrella, showcasing how collective energy can be channeled into specific, long-term goals outside existing national structures.
Major Theories Explaining Crowd Dynamics
To move beyond mere description, social scientists have developed specific theories to explain the mechanisms driving crowd behavior, a subfield that belongs broadly to the domain of social psychology. These models attempt to account for the speed, intensity, and perceived irrationality often associated with large group gatherings.
The Contagion Theory was formulated by Gustave Le Bon. This theory posits that crowds exert a powerful, almost hypnotic influence over their members, leading individuals to abandon personal responsibility in favor of the collective emotion. Shielded by anonymity, participants surrender to the contagious feelings of the crowd, which assumes a life of its own, driving people toward potentially irrational or violent action. While foundational, critics often argue that the concept of a singular “collective mind” has not been systematically documented and that collective emotions are not necessarily irrational, even if intense.
The Convergence Theory offers a contrasting view, suggesting that crowds do not cause people to act in a certain way; rather, people who already share a desire to act in a specific manner congregate to form the crowd. This theory asserts that individuals with similar underlying attributes or tendencies seek out like-minded persons with whom they can collectively express or release those tendencies. The crowd environment facilitates this release by diffusing individual responsibility and intensifying shared sentiment, effectively creating a critical mass of pre-disposed participants.
The Emergent-Norm Theory, developed by Ralph Turner and Lewis Killian, posits that crowds begin as collectivities composed of individuals with mixed interests and motives. Particularly in less stable crowds (such as acting or protest crowds), established norms are vague or rapidly changing. As the event unfolds, participants collectively develop new, temporary rules of behavior. For example, if one individual spontaneously begins looting during a protest, and others follow suit, a new, albeit temporary, norm of action has emerged. This theory emphasizes the role of decision-making, where individuals take on different roles—leaders, followers, bystanders, or opponents—as the collective rules are created in real time.
Significance, Impact, and Rationality
The study of collective behavior has proven vital to psychology and sociology because it addresses the gap between individual action and formalized social structures, providing tools to analyze rapid social change, social movements, and instances of mass hysteria or enthusiasm. The field struggled for many years but achieved significant progress with the publication of Neil Smelser’s 1962 work, Theory of Collective Behavior, which is considered a landmark text of the 20th century. The social disturbances of the late 1960s and early 1970s further fueled interest, inspiring empirical research that challenged the purely “armchair sociology” of earlier students of the subject.
A significant modern challenge to the traditional view of collective behavior, especially regarding panics, comes from game theory. Panics, often cited as the purest form of irrational collective behavior, are re-examined through a rational choice lens. Game theory suggests that even during a panic, such as in a burning theater, actors may be conducting themselves rationally based on their perception of immediate risk and limited resources (like exits). If audience members collectively decide that running, rather than walking, offers a better probability of survival, the resulting stampede, while appearing animalistic, is in fact the rational outcome of individual utility maximization under extreme duress.
Today, the principles derived from the study of collective behavior are applied across various domains. In marketing, understanding the dynamics of the mass helps predict consumer crazes and rapid shifts in brand loyalty. In political science, these theories help analyze the formation and mobilization of publics and the success or failure of social movements. Furthermore, in disaster management, recognizing the mechanisms of panic and emergent norms is crucial for developing effective communication and evacuation strategies, ensuring that collective action enhances, rather than hinders, safety.
