Collectivism is a cultural value that is characterized by emphasis on cohesiveness among individuals and prioritization of the group over self. Individuals or groups that ascribe to a collectivistic worldview tend to find common values and goals as particularly salient and demonstrate greater orientation toward in-group than toward out-group. The term “in-group” is thought to be more diffusely defined for collectivistic individuals to include societal units ranging from the nuclear family to a religious or racial/ethnic group. Meta-analytic findings support that collectivism shows a consistent association with discrete values, interpersonal patterns of interaction, cognition, perception and self-construal. Collectivism is often discussed alongside the cultural value of individualism, but these are two distinct concepts and are not considered to be opposites.
Origins and historical perspectives 
The German sociologist Tönnies described an early model of collectivism and individualism using the terms Gemeinschaft (community) and Gesellschaft (society). Gemeinschaft relationships, in which communalism is prioritized, were thought to be characteristic of small, rural village communities. An anthropologist, Redfield (1941) echoed this notion in work contrasting folk society with urban society.
Weber (1930) contrasted collectivism and individualism through the lens of religion, believing that Protestants were more individualistic and self-reliant compared to Catholics, who endorsed hierearchical, interdependent relationships among people.
Hofstede (1980) was highly influential in ushering in an era of cross-cultural research making comparisons along the dimension of collectivism versus individualism. Hofstede conceptualized collectivism and individualism as part of a single continuum, with each cultural construct representing an opposite pole. The author characterized individuals that endorsed a high degree of collectivism as being embedded in their social contexts and prioritizing communal goals over individual goals. The notion that collectivism-individualism is unidimensional has been challenged by contemporary theorists.
Collectivism was an important part of "Marxist–Leninist ideology in the "Soviet Union, where it played a key part in forming the "New Soviet man, willingly sacrificing his or her life for the good of the collective and fully replaceable. Terms such as "collective" and "the masses" were frequently used in the official language and praised in "agitprop literature, for example by "Vladimir Mayakovsky (Who needs a "1") and Bertolt Brecht ("The Decision, "Man Equals Man).
Terminology and measurement
The construct of collectivism is represented in empirical literature under several different names. Most commonly, the term interdependent self-construal is used. Other phrases used to describe the concept of collectivism-individualism include allocentrism-idiocentrism, collective-private self, as well as subtypes of collectivism-individualism (meaning, vertical and horizontal subtypes). Inconsistencies in terminology is thought to account for some of the difficulty in effectively synthesizing the empirical literature on collectivism.
Typically, collectivism is measured via self-report questionnaire. Meta-analytic findings suggest that there are six instruments that have been used to measure collectivism (and the related construct of individualism) in a manner that best reflects current theoretical thinking.
- Gudykunst and colleagues developed a 28-item measurement tool that rates items on a scale from 1-7. Interdependent and independent self-construal subscales are produced. Sample items from the interdependent subscale include, "I maintain harmony in the groups of which I am a member" and "I will sacrifice my self-interest for the benefit of the group."
- Kim and Leung developed the Revised Self-Construal Scale, which is a 28-item measure that produces Interdependent and independent self-construal subscales. Sample items from the interdependent subscale include, "I feel uncomfortable disagreeing with my group" and "My relationships with others in my group are more important than my personal accomplishments."
- Oyserman developed a measure containing 18 items rated on a five point Likert scale which produces collectivism and individualism subscales. An example item from the collectivism subscale include "In order to really understand who I am, you must see me with members of my group."
- Singelis developed the 24-item Self-Construal Scale, which rates items on a scale from 1-7. Items from the interdependent subscale include, "My happiness depends on the happiness of those around me" and "If my brother or sister fails, I feel responsible."
- Takata developed a 20-item measure that was originally published in Japanese. It contains a collectivism and an individualism subscale.
- Triandis developed a 12-item measure that produces collectivism and individualism subscales. The person completing the question is asked "Are you a person who is likely to..." and then asked to rate a number of scenarios. Examples of scenarios that if endorsed would indicate greater adherence to collectivism include "Stay with friends, rather than at a hotel, when you go to another town (even if you have plenty of money)."
In one critical model of collectivism, Markus and Kitayama describe the interdependent (i.e., collectivistic) self as fundamentally connected to the social context. As such, one’s sense of self depends on and is defined in part by those around them and is primarily manifested in public, overt behavior. As such, the organization of the self is guided by using others as a referent. That is, an interdependent individual uses the unexpressed thoughts, feelings, and beliefs of another person with whom they have a relationship with, as well as the other person’s behaviors, to make decisions about their own internal attributes and actions.
Markus and Kitayama also contributed to the literature by challenging Hofstede’s unidimensional model of collectivism-individualism. The authors conceptualized these two constructs bidimensionally, such that both collectivism and individualism can be endorsed independently and potentially to the same degree. This notion has been echoed by other prominent theorists in the field.
Some researchers have expanded the collectivism-individualism framework to include a more comprehensive view. Specifically, Triandis and colleagues introduced a theoretical model in which incorporates the notion of relational contexts. The authors argues that the domains of collectivism and individualism can be further described by horizontal and vertical relationships. Horizontal relationships are believed to be status-equal whereas vertical relationships are characterized as hierarchical and status-unequal. As such, horizontal collectivism is manifested as an orientation in which group harmony is highly valued and in-group members are perceived to experience equal standing. Vertical collectivism involves the prioritization of group goals over individual goals, implying a hierarchical positioning of the self in relation to the overarching in-group. The horizontal-vertical individualism-collectivism model has received empirical support and has been used to explore patterns within cultures. 
Originated by W. E. B. DuBois, some researchers have adopted a historical perspective on the emergence of collectivism among some cultural groups. DuBois and others argued that oppressed minority groups contend with internal division, meaning that the development of self-identity for individuals from these groups involves the integration of one’s own perceptions of their group as well as typically negative, societal views of their group. This division is thought to impact goal formation such that people from marginalized groups tend to emphasize collectivistic over individualistic values.
Some organizational research has found different variations of collectivism. These include institutional collectivism and in-group collectivism. Institutional collectivism is the idea that a work environment creates a sense of collectivist nature due to similar statuses and similar rewards, such as earning the same salary. In-group collectivism is the idea that an individual's chosen group of people, such as family or friend groups, create a sense of collectivist nature. In-group collectivism can be referred to as family collectivism.
A number of classic studies have demonstrated that there is a relationship between collectivism and cognition. These studies support the notion that people from collectivistic cultures tend to demonstrate a holistic cognitive style, which is reflected in processes such as memory, visual perception, attributional style, and categorization schemas. This effect has been replicated extensively by independent research groups, supporting its robustness.
- Memory: Masuda and Nisbett showed that Japanese students, who were presumed to hold greater collectivistic views, demonstrated greater attention to the context in which a visual stimulus was embedded and resultantly, exhibited more holistic memory compared to North American students.
- Visual perception: During a “rod and frame” test, in which a person is asked to determine the angle of a rod in relation to a frame, East Asian participants were more likely be “field dependent” than Americans, meaning that they were more biased by the orientation of the frame. Again, these findings suggest that people from more collectivistic cultures tend to be more context dependent in their perception than people from more individualistic cultures.
- Attributional style: Participants were shown a picture of a group of fish and asked to rate the reasons they believed one fish was swimming in front of the group. Chinese participants were more likely to endorse external forces (for example, “the fish is being chased”) compared to Americans, who endorsed more internal forces (for example, “the fish is a leader”).
- Categorization schemas: Collectivism has been shown to influence how people sort and group. Individuals who are more collectivistic tend to think about the relationship of objects and sort on that basis rather than by shared properties. For example, when Chinese children were asked to indicate which two objects were alike from a cow, chicken, and a patch of grass, most selected the cow and the grass. When probed about the reasons for this grouping, it was explained that cows eat grass.
Development of self-concept
An individual’s self-concept can be fundamentally shaped by cultural values. Such processes typically begin in childhood and adolescence and parents are often one of the first critical inputs that shape a child’s sense of self-concept. Parents with more collectivistic world views have been shown to speak and interact with their children in a manner that conveys the core tenets of collectivism, such as emphasis on the relationships between objects and interpersonal connections. As such, youth who are parented in this manner tend to develop a sense of self that is defined in relation to others. This sense of self also has been found to be reflected in patterns of structural and functional connectivity in the brain. For example, generally the medial prefrontal cortex (MPFC) is more active when adults think about themselves compared to when they think about someone else. However, for adults who endorse collectivism, the MPFC actually shows greater response when they think about themselves in the context of their close relationships.
Cultural views are believed to have a reciprocal relationship with macro-level processes such as economics, social change, and politics. Societal changes in China exemplifies this well. Beginning in the early 1980’s, China experienced dramatic expansion of economic and social structures, resulting in greater income inequality between families, less involvement of the government in social welfare programs, and increased competition for employment. Corresponding with these changes was a shift in ideology among Chinese citizens, especially among those who were younger, away from collectivism (the prevailing cultural ideology) toward individualism.  China also saw this shift reflected in educational policies, such that teachers were encouraged to promote the development of their students’ individual opinions and self-efficacy, which prior to the aforementioned economic changes, was not emphasized in Chinese culture.
Attempts to study the association of collectivism and political views and behaviors has largely occurred at the aggregate national level. However, more isolated political movements have also adopted a collectivistic framework. For example, "Collectivist anarchism (also known as anarcho-collectivism) is a revolutionary "anarchist doctrine that advocates the abolition of both the "state and "private ownership of the "means of production. It instead envisions the means of production being owned collectively and controlled and managed by the producers themselves.
