Notes: Societies to Social Networks (6.1–6.3)
6.1 Societies and Their Transformations
Key idea: Society is the largest and most complex group that sociologists study; it consists of people who share a culture and a territory. The type of society we live in shapes who we become and how we think and feel. Technology is central to sweeping changes across societies.
Major historical sequence (as shown in Figure 6.1–6.2):
Hunting and gathering societies
Pastoral and horticultural societies
Agricultural societies
Industrial societies
Postindustrial (information) societies
Biotech societies (emerging?).
The revolutions that drive change:
First Social Revolution: Domestication (animals and plants) → pastoral and horticultural societies.
Second Social Revolution: Agricultural (invention of the plow) → agricultural society.
Third Social Revolution: Industrial (steam engine) → industrial society.
Fourth Social Revolution: Information (microchip) → postindustrial information society.
Fifth Social Revolution?: Biotech (genetic engineering, decoding the genome) → biotech society (emerging).
Landscape of change (core idea): technology, especially the plow, steam engine, microchip, and DNA/genomics, reorganizes production, trade, power, and social structure.
Hunting and Gathering Societies (characteristics):
Small groups, few social divisions, little inequality; nomadic; rely on hunting and gathering for survival.
Food supply perishes quickly; men tend to be hunters, women gatherers contribute about 3/4 of total food (in many groups).
Surplus is minimal, leading to egalitarian social relations; no formal rulers; decision-making often by discussion.
Group size typically 25–40 people; leisure relatively high; significant sharing of food.
Life expectancy is affected by disease, drought, pestilence; many groups now endangered or extinct due to external pressures.
Shamans (spiritual healers) often play a role; belief systems tied to survival strategies.
Pastoral and Horticultural Societies (characteristics):
Domestication led to two branches:
Pastoral (animal herding): nomadic, following pastures; social roles shift with animal husbandry; leadership often linked to wealth from livestock.
Horticultural (plant cultivation with hand tools): permanent settlements due to reliable plant food supply.
Consequences: more complex division of labor; surplus enables trade and accumulation of goods; early forms of social inequality and wealth accumulation; emergence of chiefs and formal leadership structures.
Female status and gender roles debated; theories (e.g., Elise Boulding) connect plowing and cattle care with male dominance in later agricultural transitions; questions about why men came to dominate certain forms of agriculture.
Figure 6.2 (illustrative) shows how domestication and plant cultivation ripple into larger surplus, trade, inequality, and the emergence of wealth and power, including inherited wealth and organized leadership.
Agricultural Societies (characteristics):
Invention of the plow (roughly 5–6 thousand years ago) dramatically increases productivity; larger surpluses support cities and a broader culture (philosophy, art, music, literature, architecture).
Inventions such as the wheel, writing, and numbers underpin civilization.
Surpluses intensify inequality: control of resources (land, animals, jewelry, taxes/tribute) concentrates wealth and power; emergence of states and coercive institutions to protect privileges.
Gender dynamics: shifting roles with new technological demands; debate about when and how women’s status shifts occurred (e.g., Boulding’s theory of male control of plowing and cattle).
Industrial Societies (characteristics):
Industrial Revolution (Britain, 1765 onward) marks shift to machine production powered by fuels (e.g., steam); “goods produced by machines” rather than by human/animal labor.
Rapid urbanization; large labor force; poor working conditions; early resistance: no rights to unionize, unsafe conditions, and private security suppression.
Over time, labor movements win basic rights: union rights, safer conditions, and collective bargaining.
Industrialization brings abundant goods and rising living standards for many; expansion of civil rights, abolition of slavery, expansion of political rights, and broader social equality movements (women, minorities).
Social inequality persists and evolves, but improvements in some indicators (ownership, healthcare, education) accompany industrial growth.
Postindustrial (Information) Societies (characteristics):
A new era dominated by information and services rather than raw materials and manufacturing.
The hallmark is information and services: teachers, lawyers, doctors, bankers, interior designers provide knowledge-based services rather than producing tangible goods.
The United States and other Western nations shift toward service industries; social transformations include driverless cars, global communication, and pervasive information technologies.
This shift leads to the “postindustrial” or information society; a new economy centered on applying and transmitting information.
Biotech Societies (Emerging?):
A potential new form of society in which economy emphasizes modifying genetics to produce food, medicine, and materials.
Examples discussed (some speculative, some real):
Tobacco and health claims; corn that blocks herpes and pregnancy; spider silk in goats; transgenic animals producing medicines; bacteria excreting diesel fuel; biotransgenics and cloning implications.
Debates about cloning and genetic modification raise ethical and social questions about what constitutes family, parenthood, and human identity.
Possible starting points for biotech: identification of DNA structure in 1953 by Crick and Watson, and the decoding of the human genome in 2001.
Key terms to know:
social group: people who interact with one another and share a sense of belonging.
society: large, complex group that shares a culture and a territory.
domestication revolution: first social revolution, based on domestication of plants/animals; leads to pastoral/horticultural societies.
agricultural revolution: second social revolution, based on the plow; leads to agricultural societies.
industrial revolution: third social revolution, powered by machines; leads to industrial society.
postindustrial (information) society: fourth revolution, driven by information technology and services.
biotech society: potential fifth revolution, based on genetic modification;
aggregate: individuals in the same space but not as a group with shared identity.
category: a statistical grouping of people or things with similar characteristics.
hunting and gathering: earliest, simplest form of society relying on hunting and gathering food; characterized by egalitarianism and nomadism.
primary group: intimate, face-to-face, long-term interactions (e.g., family).
secondary group: larger, more anonymous, formal groups based on shared interests or activities.
in-group/out-group: groups toward which one feels loyalty vs. groups toward which one feels antagonism; important for perception and morality.
reference group: groups we compare ourselves to when evaluating our behavior and life choices.
social network: web of social ties that connects people.
The opening vignette (Monster Cody) is used to illustrate how groups influence individuals, especially how an in-group can in-group identity and member loyalty can become entwined with violent gang life. It also frames the broader discussion of how group affiliation shapes beliefs and behavior.
Summary takeaway: As society evolves through different technological stages, groups within society (primary/secondary; in-groups/out-groups; reference groups; social networks) influence our self-concept, opportunities, and behavior. The shift toward information and biotech economies introduces new ethical, moral, and social questions about identity, family, and governance.
6.1 Key concepts and numerical references
Major societies and transformations:
Hunting and gathering
Pastoral and horticultural
Agricultural
Industrial
Postindustrial (information)
Biotech (emerging)
First to Fifth revolutions (terminology and sequence):
Domestication revolution → pastoral & horticultural
Agricultural revolution → agricultural society
Industrial Revolution → industrial society
Information revolution → postindustrial society
Biotech evolution → biotech society (emerging)
Figures and relationships:
Dyad: 2 people; Triad: 3; larger groups: 4, 5, etc.
Number of inter-person relationships in a fully connected group of size n:R(n)=inom{n}{2}= rac{n(n-1)}{2}. For example: two people have 1 relationship (1); three people have 3 relationships (3); four people have 6 relationships (6); five people have 10 relationships (10); six people have 15 relationships (15); seven people have 21 relationships (21); eight people have 28 relationships (28); nine people have 36 relationships (36); ten people have 45 relationships (45).
Milestone statistics in social networks:
Milgram’s small-world experiment: average path length ≈ 6 steps; concept of “six degrees of separation.”
Replications and critiques:
Judith Kleinfeld (2002b) replicated Milgram; findings varied; one replication showed only about 30% of letters reached the target; general replication outcomes depend on samples and methods.
Later research on large-scale networks shows shorter paths in some networks: roughly less than 7 steps in 250 million chat exchanges; less than 5 steps in Facebook networks, highlighting variation by data source and method. See sources cited in the text (Dodds et al. 2003; Muhamad 2010; Markoff & Sengupta 2011; Mehrabian 2017).
Asch and Milgram experiments (classic tests of group influence):
Asch (1952): about 33% of participants conformed to the group at least half the time; 40% conformed some of the time; 25% remained independent (stood firm and gave correct answers). These results illustrate strong peer pressure even among strangers.
Milgram (1963, 1965): level of obedience to authority tested via shocks; outcomes varied with setup; overall, many participants continued to obey orders even when the learner appeared to suffer; later variants showed that diminishing authority or adding a dissenting peer dramatically reduced obedience (5% in certain two-teacher conditions; 65% under no feedback; 40% with visible learner in distress; 80% in a “Game of Death” variant).
Groupthink (Irving Janis): a phenomenon where the desire for group harmony leads to faulty decision-making; key characteristics include collective tunnel vision, suppression of dissent, and failure to examine alternatives; historical examples include Pearl Harbor misinterpretations, Vietnam-era decisions, and post-9/11 interrogation practices (e.g., waterboarding) that illustrate the danger of organizational conformity.
Thinking critically prompts:
How would orientations to life differ in various ancient societies?
How do in-groups and out-groups shape perception and morality?
How has peer pressure operated in your life? Give a personal example.
6.2 Groups within Society
Anomie (Durkheim): sense of normlessness; small groups help prevent anomie by buffering individuals from the vastness and impersonal nature of larger society.
Aggregates vs. categories:
Aggregate: individuals temporarily sharing the same space but not viewing themselves as a group (e.g., shoppers in a checkout line).
Category: a statistic grouping based on shared characteristics (e.g., all college women wearing glasses); members don’t see themselves as belonging to a group and do not interact.
Primary groups (Cooley): intimate, face-to-face association; fundamental in shaping social nature and ideals; e.g., family and close friends; primary groups provide emotional support and a sense of self. They function as a mirror within, shaping our self-concept.
Secondary groups: larger, more anonymous, formal, and impersonal; built around shared interests or activities and specific statuses (e.g., classes, professional associations, political parties). Essential for modern life but often insufficient for deep belonging; they’re stabilized by primary-group buffers formed within them.
In-groups and out-groups:
In-group: groups toward which members feel loyalty and belonging.
Out-group: groups toward which members feel antagonism or hostility.
Consequences: in-groups shape perception, morality, and behavior; can foster prejudice and discrimination; can lead to double standards (e.g., different judgments for men vs. women).
Examples: Monster Kody and the Crips (in-group) vs. Bloods (out-group); post-9/11 policies toward out-groups; Nazi-era persecution of Jews.
Reference groups:
Groups we use to evaluate ourselves and our own behavior; can be groups we are not members of (e.g., graduate students in a desired profession).
Influence: can prompt changes in dress, language, major, and other life choices to align with the reference group.
Examples: Amish family’s expectations vs. corporate career goals; tension between pacifist families and military ambitions.
Social networks:
The core of social life; families, friends, coworkers, and acquaintances connected in a web of relationships.
A clique is a cluster within a larger group where interaction is dense and regular.
Networks can influence career outcomes (e.g., job opportunities flowing through trusted connections).
For Your Consideration (inequality):
Social networks can perpetuate social inequality by circulating opportunities through homophilous (similar) networks; the “good old boys” network can bypass women and minorities.
Strategies to break cycles include building diverse networks and expanding cross-cutting connections (professional associations, clubs, online networks).
6.3 Group Dynamics
Small group vs. larger group dynamics:
A small group allows direct interaction among all members (dyad, triad, etc.).
As group size increases, intimacy tends to decline while stability increases and formal structures emerge.
Dyad, triad, and group growth:
Dyad (two members): most intimate, but unstable; if one leaves, the group collapses.
Triad (three): interaction shifts; triads can form coalitions and may need an arbitrator; but triads can still be unstable due to coalitions.
With each new member, the number of possible inter-member connections grows rapidly: for a group of size n, the number of connections is R(n)=inom{n}{2}= rac{n(n-1)}{2}. See the growing pattern in Figure 6.3.
As group size increases beyond three, formal leadership and role differentiation emerge (president, secretary, treasurer).
Effects of group size on attitudes and behavior:
In small groups, informal interaction dominates; as groups grow, members adopt more formal communication and behavior to address the larger audience.
The diffusion of responsibility can occur in larger groups when urgent tasks arise (e.g., helping a person in distress in a staged setting by Darley and Latané).
Leadership types and styles:
Instrumental (task-oriented) leaders keep the group moving toward goals; can create friction and lower popularity because of direct demands.
Expressive (socioemotional) leaders boost harmony, morale, and cohesion; usually more popular but less focused on concrete tasks.
A leader can be instrumental or expressive, but typically not both simultaneously; effective leadership often requires balancing these roles.
Leadership styles:
Authoritarian: gives orders, directs tasks; can lead to dependence and potential resentment when overused.
Democratic: seeks consensus, outlines steps, uses facts to justify decisions; tends to yield higher group satisfaction and ongoing cooperation.
Laissez-faire: highly permissive; can lead to lack of direction and lower achievement in many contexts.
Classic experiments (Lippitt & White): authoritarian leadership led to dependence and aggression; democratic leadership fostered cooperation; laissez-faire led to low achievement. Note: gender/selection biases in the study.
Leadership in changing contexts:
Situational leadership suggests different contexts require different styles (e.g., emergency vs. routine group work; crisis requires authoritative action; routine tasks benefit from democratic collaboration; completely open-ended tasks may suit laissez-faire).
Asch’s conformity experiment (peer pressure):
In a lab with six confederates and one real subject, about 33% conformed to the incorrect majority on at least half of the trials; 40% conformed at least once; 25% never conformed. This demonstrates powerful peer pressure even among strangers.
Milgram’s obedience study (authority):
Participants were instructed to administer increasingly higher shocks to a learner; many continued to obey despite the learner’s apparent distress, especially when an authority figure urged continuation.
Variations show obedience drops when a dissenting teacher or second authority figure reduces pressure; ethics concerns later limited replication.
The findings illuminate how authority and conformity can lead to potentially harmful actions, including historical examples of state-sponsored atrocities.
Groupthink (Janis):
A process by which a group narrows its thinking to a single course of action, suppressing dissenting viewpoints and ignoring risks.
Examples: decisions before Pearl Harbor, Vietnam War decisions, and post-9/11 policies (including interrogation methods) illustrate how groupthink can lead to disastrous outcomes.
Prevention strategies: promote diverse opinions, encourage critical evaluation, and facilitate the circulation of independent research and external viewpoints.
Thinking critically about group dynamics:
How do small-group dynamics translate to real-world leadership and policy decisions?
What are the ethical implications of experiments like Asch and Milgram, and how have debates about research ethics evolved?
How can organizations mitigate groupthink while maintaining effective decision-making?
Applications and real-world implications:
The New World of Work: globalization, outsourcing, and subcontracting alter job stability and how paychecks are earned.
Social networks as career assets: building diverse and broad networks can help in job searches and career advancement; many opportunities are filled through personal connections before public announcements.
The Small World Phenomenon remains debated; recent data from online networks show shorter path lengths in some platforms but may depend on sampling and measurement.
For Your Consideration (discussion prompts):
How do in-groups, reference groups, and social networks perpetuate social inequality? What strategies could reduce inequality within networks?
How might you diversify your network to broaden opportunities?
What leadership style would you use in a given scenario (emergency vs. routine task) and why?
Connecting to broader themes:
The chapter links micro-level group processes to macro-level societal transformation, showing how small groups and large-scale structures interact in shaping life chances, values, and identities.
Ethical, philosophical, and practical implications arise in technology (cloning, genomics), social organization (leadership and conformity), and public policy (groupthink and state decisions).
6.2–6.3 Connections to earlier material
Anomie and social integration: Durkheim’s concept of anomie helps explain why small groups function as buffers against normlessness, reinforcing the need for intimate social ties in modern life.
Social reproduction of inequality: The structure of in-groups, reference groups, and social networks helps explain why opportunities often flow to those with similar backgrounds; this aligns with broader themes of social stratification and mobility.
The role of technology in group dynamics: As technology reshapes how we connect (social networks, Milgram-style studies on connectivity, and the rise of the biotech economy), our understanding of group processes and leadership must adapt to new social landscapes.
6.2–6.3 Key formulas and data
Group connections: For a group of size n, the number of direct interpersonal connections is
R(n)=inom{n}{2}= rac{n(n-1)}{2}.Asch’s conformity outcomes (classic results):
About 33% conformed to the group at least half the time.
About 40% conformed some of the time.
About 25% never conformed to the group.
Milgram’s obedience outcomes (classic variations):
When the learner’s feedback was not available, 65% pushed the lever to the maximum (450 volts).
When the learner’s feedback was visible, 40% reached 450 volts.
With a second dissenting teacher, only 5% reached the maximum.
Small-world benchmarks:
Milgram: average path length ≈ 6 steps.
Modern large-scale network studies suggest much shorter paths in some platforms (e.g., under 7 steps in large email/chat networks; under 5 steps in Facebook networks), highlighting methodological differences across studies.
Evolutionary social changes (core chain):
Domestication → pastoral/horticultural societies.
Plow invention → agricultural society, larger surpluses, cities, culture, writing, numbers.
Steam engine → industrial society, mass production, urbanization, class-based conflict and labor movements.
Microchip → postindustrial/information society, service and knowledge economy.
Biotech developments → potential biotech society, with genetics-driven economy and new ethical questions.
For Your Consideration / Applying Sociology to Your Life (highlights)
Social networks and inequality: Your in-groups, reference groups, and networks tend to be similar to you; this can perpetuate social inequality unless deliberate cross-cutting ties are built (diversity in networks).
Building career resilience: In the postindustrial era, cultivate a broad, diverse network across organizations and sectors; participate in professional associations, attend meetings, and volunteer for committees; leverage online networks to maintain connections.
Cloning and biotechnology thought experiments: Explore ethical questions about identity, parenthood, and social relationships in biotech futures; think about how new technologies might reframe human relationships and societal norms.
Leadership and crisis: In emergency contexts, authoritative leadership can be effective; in routine contexts, democratic leadership tends to produce sustainable engagement; avoid extremes of laissez-faire when safety/stability are at risk.
Groupthink and governance: Recognize signs of groupthink in organizations and governments; advocate for diverse viewpoints and independent research to prevent policy missteps or ethical compromises.
6.2–6.3 Summary takeaways
Societies transform via intertwined technological revolutions that reshape production, inequality, leadership, and social roles.
Groups within society—from intimate primary groups to large secondary groups and networks—shape our sense of self, opportunities, and behavior.
Group dynamics reveal that size, leadership style, conformity, obedience to authority, and the risk of groupthink can profoundly affect individual and collective outcomes.
Real-world implications span labor markets, politics, law, and bioethics; analyzing these phenomena requires leveraging theory (anomie, in/out-groups, reference groups) alongside empirical studies (Asch, Milgram, Milgram’s successors, small-world research).
