Summary

1. Social groups are the building blocks of social life, and it is virtually impossible to imagine a society without groups and difficult to imagine individuals not being involved with many types of groups. They are distinguished from social categories and social aggregates by the degree of interaction among their members and the identification of their members with the group.
2. Primary groups are small and involve strong emotional attachments, while secondary groups are larger and more impersonal. Some groups become in-groups and vie, sometimes hostilely, with people they identify as belonging to out-groups. Reference groups provide standards by which we judge our attitudes and behavior and can influence how we think and act.
3. Social networks connect us through the people we know to other people they know. They are increasingly influential for successful employment but are also helpful for high-quality health care and other social advantages.
4. The size of groups is a critical variable for their internal dynamics. Compared to large groups, small groups involve more intense emotional bonds but are also more unstable. These differences stem from the larger number of relationships that can exist in a larger group than in a smaller one.
5. Instrumental and expressive leaders take different approaches in exercising leadership. Instrumental leaders focus more on solving tasks, even at the risk of alienating group members, while expressive leaders focus more on group relations. Of the three major styles of leadership—authoritarian, democratic, and laissez-faire—laissez-faire leadership seems the least effective in helping a group achieve its goals.
6. Women and men are equally effective as leaders but exhibit different leadership styles. Women tend to be expressive leaders, while men tend to be more authoritarian leaders. Women leaders still face problems in securing the respect of the group members they seek to lead.
7. Processes of group conformity are essential for any society and for the well-being of its many individuals but also can lead to reprehensible norms and values. People can be influenced by their group membership and the roles they’re expected to play to engage in behaviors most of us would condemn. Laboratory experiments by Asch, Milgram, and Zimbardo illustrate how this can happen, while a real-life classroom experiment called the Third Wave dramatized how a fascist atmosphere could develop from everyday group processes.
8. Formal organizations are commonly delineated according to the motivations of the people who join them. According to Etzioni’s popular typology, three types of formal organizations exist: utilitarian, normative, and coercive.
9. Max Weber outlined several characteristics of bureaucracy that he felt make them the most efficient and effective type of large formal organization possible. At the same time, other scholars have pointed to several disadvantages of bureaucracies that limit their efficiency and effectiveness and thus thwart organizational goals.
10. Robert Michels hypothesized that the development of oligarchies in formal organizations and political structures is inevitable. History shows that such “oligarchization” does occur but that society remains more democratic than Michels foresaw.
11. Women and people of color have long been involved in normative organizations and continue to expand their numbers in utilitarian organizations, but in the latter they lag behind white men in rank and salary. In a major type of coercive organization, prisons, people of color and men are overrepresented. The chapter closes with the question of whether the reason for this overrepresentation is the offending rates of these two groups or, instead, discrimination against them in criminal justice processing.
