- Social Patterns — 10–15% (~10–15 questions): Culture, demography, human ecology, rural/urban
- Social Processes — 25–30% (~25–30 questions): Socialization, groups, deviance, social change, collective behavior
- Social Stratification — 20–25% (~20–25 questions): Class, race, gender, aging, inequality
- The Sociological Perspective — 20–25% (~20–25 questions): Theory, research methods, key concepts
The Sociological Perspective
20–25%The Sociological Imagination
Coined by C. Wright Mills, the sociological imagination is the ability to see the connection between personal troubles and larger social forces. For example, unemployment isn't just a personal failure — it's connected to economic structures, trade policy, and social class.
Society is like an organism — each part (institution) serves a function that contributes to stability. When all parts work together, society is in equilibrium. Focuses on consensus and social order.
Society is characterized by inequality and conflict between groups competing for power and resources. The dominant class maintains control through economic, political, and cultural means. Focuses on power and inequality.
Society is constructed through everyday interactions and shared symbols. People act based on the meanings they attach to things, and meanings emerge from social interaction. Focuses on micro-level face-to-face behavior.
Merton's Functions
- Manifest functions — Intended, recognized consequences of a social institution (e.g., schools teach academic skills)
- Latent functions — Unintended, unrecognized consequences (e.g., schools provide childcare, facilitate peer socialization)
- Dysfunctions — Elements that may disrupt social stability (e.g., high dropout rates reducing social mobility)
Research Methods
- Survey — Questionnaires or interviews with a sample; good for large populations; may have response bias
- Experiment — Controls variables to test cause and effect; independent variable is manipulated, dependent variable is measured; uses control and experimental groups
- Participant Observation / Ethnography — Researcher immerses in a group; rich qualitative data; risk of "going native" (losing objectivity)
- Secondary Analysis — Using existing data (census, historical records)
- Content Analysis — Systematic examination of cultural artifacts (media, texts)
Core Sociological Concepts
- Norms — Shared rules of behavior. Folkways: informal norms (table manners). Mores: norms with moral weight (no cheating). Taboos: strongest prohibitions (incest).
- Values — Culturally shared standards of desirability (freedom, success)
- Status — A social position. Ascribed: assigned at birth (race, sex). Achieved: earned through effort (doctor, criminal). Master status: overrides all others.
- Role — Behavior expected of someone in a given status. Role conflict: competing roles. Role strain: tension within a single role.
- Social control — Mechanisms that regulate behavior. Formal: laws, police. Informal: gossip, ostracism.
Social Patterns
10–15%Culture
The sum of a group's way of life — beliefs, values, norms, artifacts, and language. Culture has two components:
- Material culture — Physical objects (tools, buildings, technology)
- Non-material culture — Abstract ideas (beliefs, values, language, norms)
Key concepts:
- Ethnocentrism — Judging another culture by the standards of your own (leads to bias)
- Cultural relativism — Understanding a culture on its own terms
- Subculture — A group within a larger culture with distinct norms/values (goths, surfers)
- Counterculture — A subculture that actively opposes the dominant culture (1960s hippies)
- Cultural diffusion — The spread of cultural elements from one group to another
- Cultural lag — When non-material culture fails to keep pace with material/technological change (William Ogburn)
Demography
The scientific study of human population characteristics.
- Birthrate (CBR) — Births per 1,000 people per year
- Death rate (CDR) — Deaths per 1,000 people per year
- Fertility rate — Average number of children per woman
- Infant mortality rate — Deaths of infants under 1 per 1,000 live births; key indicator of development
- Migration — Immigration: moving into an area. Emigration: leaving.
- Population growth = Births − Deaths + Net migration
- Demographic transition — Societies move from high birth/death rates to low birth/death rates as they industrialize
- Malthus — Argued population grows geometrically while food grows arithmetically → potential for famine
- Zero population growth — When births equal deaths
Human Ecology & Urbanization
- Human ecology — The study of the relationship between humans and their physical/social environment (Park, Burgess, McKenzie — Chicago School)
- Concentric zone model — Burgess: cities expand in rings outward from a central business district
- Gemeinschaft (Tönnies) — Traditional community bonds; close-knit, personal (rural village)
- Gesellschaft (Tönnies) — Modern, impersonal, contractual relationships (urban society)
- Urbanization — Movement of populations from rural to urban areas
- Suburbanization — Movement from cities to surrounding suburbs
- Gentrification — Wealthier people move into poor urban neighborhoods, raising costs and often displacing residents
Social Processes
25–30%Socialization
The lifelong process by which people learn cultural norms, values, and roles. Agents of socialization: family (most important early on), peers, school, media, religion.
- Primary socialization — Early childhood; foundational personality formation
- Secondary socialization — Later in life; learning roles in specific institutions
- Anticipatory socialization — Preparing for a future role
- Resocialization — Discarding old norms and learning new ones (e.g., military training, prison)
- Total institutions (Goffman) — Institutions that control all aspects of life: military, prison, monasteries
- Cooley's Looking-Glass Self — We develop our sense of self based on how we think others perceive us (three components: imagining how we appear, imagining others' judgment, developing a self-concept)
- Mead's "I" and "Me" — The "I" is the spontaneous, creative self; the "Me" is the socialized, internalized social expectations
- Mead's stages — Preparatory → Play stage → Game stage → Generalized other
- Freud's stages — Id (instincts), Ego (rational), Superego (moral conscience)
Groups and Organizations
- Primary group — Small, intimate, long-lasting (family, close friends)
- Secondary group — Larger, formal, goal-oriented (coworkers, a sociology class)
- In-group — Group you belong to and identify with
- Out-group — Group you don't belong to; often viewed negatively
- Reference group — A group you compare yourself to when evaluating yourself
- Dyad — Two-person group (most fragile); Triad — Three-person group
- Formal organizations — Deliberately structured for specific goals
- Bureaucracy (Weber) — Rational, hierarchical organization with written rules, specialization, and impersonality. Features: hierarchy, specialization, written rules, impersonality, technical qualifications
- Groupthink (Janis) — Group prioritizes conformity and cohesion over critical thinking
- Oligarchy (Michels' "Iron Law") — Organizations inevitably come to be ruled by a small elite
Deviance and Social Control
Deviance — Behavior that violates social norms. Deviance is relative — what counts as deviant varies by culture, time, and place.
- Strain theory (Merton) — Deviance results when people cannot achieve culturally valued goals (success) through legitimate means. Five adaptations: conformity, innovation, ritualism, retreatism, rebellion
- Labeling theory (Becker, Lemert) — Deviance is not inherent; it's a label applied by society. Primary deviance: initial act. Secondary deviance: when someone internalizes the deviant label.
- Differential association (Sutherland) — Deviance is learned through interaction with others who have deviant attitudes
- Social bond theory (Hirschi) — People conform when they have strong bonds to society: attachment, commitment, involvement, belief
- Conflict perspective on deviance — Laws reflect the interests of the powerful; the powerless are more likely to be labeled deviant
- Stigma (Goffman) — A deeply discrediting attribute that reduces a person to a spoiled identity
- White-collar crime (Sutherland) — Crimes committed by people of high social status in the course of their occupation
Social Interaction
- Dramaturgy (Goffman) — Social life is like a theatrical performance. Front stage: behavior when others are watching. Back stage: behavior when we relax our performance.
- Impression management — Efforts to control how others perceive us
- Thomas theorem — "If men define situations as real, they are real in their consequences" (W.I. Thomas)
- Non-verbal communication — Body language, personal space (proxemics), eye contact, tone
Social Change & Collective Behavior
- Social movement — Organized collective effort to promote or resist change. Types: reformative, revolutionary, redemptive, alternative
- Resource mobilization theory — Social movements succeed based on their ability to mobilize resources (money, people, organization)
- Collective behavior — Relatively spontaneous group behavior: crowds, riots, panics, fads, fashions, rumors, mass hysteria
- Crowd types (Blumer): casual, conventional, expressive, acting
- Social change drivers: technology, environment, cultural diffusion, social movements, war, economic change
- Modernization — Process by which societies move from traditional to modern (industrial/post-industrial)
Social Stratification
20–25%Social Class
Stratification = a hierarchical ranking of groups. It is social (not individual), reproduced across generations, universal but variable, and involves both inequality and beliefs that justify it.
- Marx's two classes — Bourgeoisie (own means of production) vs. Proletariat (sell labor). False consciousness: workers accept their own oppression. Class consciousness: awareness of shared interests.
- Weber's three dimensions — Class (economic), Status (prestige), Party (political power)
- Socioeconomic status (SES) — Combined measure of income, education, and occupational prestige
- Intergenerational mobility — Change in class between generations
- Intragenerational mobility — Change in class within a single lifetime
- Horizontal mobility — Change in position at the same level
- Vertical mobility — Upward or downward movement in the stratification system
- Structural mobility — Mobility caused by changes in the economy, not individual effort
- Life chances (Weber) — Opportunities available to people based on their class position
Systems of Stratification
- Slavery — Ownership of people; most extreme form
- Caste system — Rigid, hereditary stratification (e.g., India's traditional caste system); ascribed status; endogamy enforced
- Estate system — Medieval Europe: clergy, nobility, commoners (serfs)
- Class system — Based on achieved status; most fluid; characteristic of modern societies
- Meritocracy — Ideal where position is based purely on ability and effort
Race and Ethnicity
- Race — A socially constructed category based on perceived physical differences. Has no biological validity as a natural category.
- Ethnicity — Shared cultural heritage (language, religion, customs, ancestry)
- Minority group (Wirth) — A group that experiences disadvantage and has a strong sense of group solidarity; does not have to be numerical minority
- Prejudice — Rigid, irrational attitude toward a group
- Discrimination — Unequal treatment based on group membership
- Racism — Prejudice + power; systemic disadvantage based on race
- Scapegoating — Blaming a group for problems caused by others/broader forces
- Patterns of intergroup relations: pluralism, assimilation, segregation, genocide
- Institutional discrimination — Discrimination built into social institutions, not just individual actions
Sex and Gender
- Sex — Biological distinction (male/female/intersex)
- Gender — Socially constructed roles, behaviors, and identities associated with sex
- Gender socialization — Learning gender-appropriate behavior through family, media, and peers
- Patriarchy — A system in which men hold primary power and women are systematically subordinated
- Glass ceiling — Invisible barriers that prevent women from advancing to top positions
- Pay gap — Women earn less than men on average; explained partly by occupational segregation and discrimination
- Feminism — Movement advocating for women's rights and gender equality. Liberal, radical, socialist/Marxist, intersectional branches.
- Intersectionality (Crenshaw) — Race, class, gender, and other identities overlap and interact to create unique experiences of privilege or oppression
Aging
- Ageism — Prejudice and discrimination based on age
- Disengagement theory — As people age, they and society mutually withdraw from each other
- Activity theory — People who remain active and engaged are more satisfied in old age
- Dependency ratio — Ratio of non-working (young + old) to working population; rising in aging societies
- Gerontology — Scientific study of aging
Institutions
15–20%Family
A social institution that serves to regulate sexuality, socialize children, provide economic cooperation, and offer emotional support.
- Nuclear family — Married couple and their children
- Extended family — Nuclear family plus additional relatives
- Endogamy — Marriage within one's social group
- Exogamy — Marriage outside one's social group
- Monogamy — One spouse; Polygamy: multiple spouses; Polygyny: one man, multiple wives; Polyandry: one woman, multiple husbands
- Patrilineal/Matrilineal — Tracing descent through father/mother
- Patrilocal/Matrilocal — Where couples reside after marriage
- Functionalist view — Family provides sexual regulation, reproduction, socialization, economic cooperation, emotional support
- Conflict view — Family reproduces class and gender inequality
- Trends: rising divorce rates, delayed marriage, cohabitation, blended families, single-parent households
Education
- Manifest functions — Transmitting knowledge, socialization, preparing for workforce
- Latent functions — Childcare, social networking, gatekeeping
- Conflict view — Education reproduces inequality; hidden curriculum teaches submission to authority and class norms
- Credentialism — Overemphasis on educational credentials relative to the actual skills needed for a job
- Tracking — Grouping students by ability; tends to reinforce class and race stratification
- Cultural capital (Bourdieu) — Non-financial social assets (knowledge, behaviors, skills) that promote social mobility
- Symbolic interactionist view — Self-fulfilling prophecy: teacher expectations affect student performance (Pygmalion effect / Rosenthal)
Religion
- Durkheim — Religion divides world into sacred and profane. Functions to create social cohesion and collective conscience. Identified totemism as the most basic religion.
- Marx — Religion is the "opiate of the masses" — an ideological tool that pacifies the working class
- Weber — Protestantism (especially Calvinism) fostered the "Protestant ethic" — work, thrift, self-discipline — which contributed to the rise of capitalism
- Church — Large, formal, bureaucratic religious organization aligned with the state
- Sect — Small, fervent, often breakaway group that rejects mainstream religion
- Cult / New Religious Movement — Novel or unconventional belief system, often led by a charismatic figure
- Secularization — The declining influence of religion in public life as societies modernize

- Sick role (Parsons) — Social expectations for ill people: exempt from duties, must want to get well, must seek medical care
- Medicalization — The process by which non-medical problems become defined as medical issues
- Social epidemiology — Study of how social factors (class, race, gender) influence health and disease distribution

Mills coined this term to describe the ability to see how personal troubles are rooted in broader social structures. Verstehen is Weber's concept of empathic understanding; the looking-glass self is Cooley's theory of self-development.
Functionalism views society like an organism where each part serves a purpose. Key theorists: Durkheim, Parsons, Merton. Conflict theory focuses on power and inequality; symbolic interactionism focuses on micro-level interaction.
Goffman's dramaturgy sees social interaction as a performance. We manage impressions on the "front stage" and relax on the "back stage." This falls under symbolic interactionism.
Participant observation (ethnography) involves immersing in a group to gather rich qualitative data. A risk is "going native" — losing objectivity by becoming too involved.
Cooley's looking-glass self has three components: (1) imagining how we appear to others, (2) imagining their judgment, and (3) developing feelings about ourselves based on that imagined judgment.
Manifest = intended, recognized (e.g., school teaches academics). Latent = unintended, unrecognized (e.g., school provides childcare, creates friendships). Dysfunctions are elements that disrupt stability.
Durkheim's four types: Egoistic (too little integration), Altruistic (too much integration — dying for the group), Anomic (too little regulation/normlessness), Fatalistic (too much regulation, like in slavery).
Socialization is the lifelong process of learning culture. The primary agents are family, peers, school, media, and religion. Primary socialization occurs in early childhood; secondary socialization occurs later in life.
Altruistic suicide results from excessive social integration — the individual's life is subordinated to the group's needs. Examples: a soldier dying for the unit, a person in an honor-bound culture.
Weber's three types: Traditional (kings, customs), Charismatic (personal magnetism — MLK, Gandhi), Rational-legal (written rules and laws — elected presidents, bureaucracies).
Merton's adaptations: Conformist (accepts goals + means), Innovator (accepts goals, rejects means — crime), Ritualist (rejects goals, keeps means — bureaucratic worker), Retreatist (rejects both — dropout, homeless), Rebel (rejects both, proposes new ones).
Primary deviance: the initial rule-breaking act. Secondary deviance: when a person accepts and acts on the deviant label applied by others. This distinction comes from Edwin Lemert and was built upon by Becker.
Deviance is socially defined and varies across cultures, time periods, and social contexts. What counts as deviant is not inherent to the act itself but depends on the norms of the group making the judgment.
Secondary groups are large, formal, and goal-oriented with impersonal relationships. Primary groups are small, intimate, and long-lasting (family, close friends). Secondary groups are characteristic of Gesellschaft society.
Bourdieu identified three forms of capital: economic (money), social (networks), and cultural (knowledge, education, tastes). Cultural capital is used to reproduce class inequality across generations.
Weber argued that the Calvinist doctrine of predestination led believers to seek signs of God's favor through hard work, frugality, and reinvestment of profit — values that aligned with capitalist development.
Parsons' sick role has four components: (1) exemption from normal duties, (2) not held responsible for illness, (3) obligated to want to recover, (4) obligated to seek competent medical help.
The glass ceiling is a metaphor for invisible, informal barriers (not laws) that prevent women and minorities from rising to the highest positions in organizations, even when they are qualified.
White-collar crime (Edwin Sutherland) refers to crimes committed by people of high social status in the course of their professional activities. Examples: embezzlement, insider trading, corporate fraud.
In a caste system, a person's rank is determined by birth and cannot be changed through individual effort. Endogamy (marrying within one's caste) enforces boundaries. India's traditional varna system is the classic example.
Cultural lag: when technology or material culture changes faster than the norms, values, and laws that govern its use. Example: the internet existed long before laws and social norms about online privacy were established.
Intersectionality recognizes that people have multiple identities (race, gender, class, sexuality, disability) that interact. A Black woman's experience of discrimination is not simply "Black discrimination + women's discrimination" — it is a unique combination.
Goffman identified three types of stigma: (1) physical deformities, (2) blemishes of character (mental illness, addiction, criminal record), (3) tribal stigma (race, ethnicity, religion). The stigmatized person has a "spoiled identity."
Qualitative data is non-numerical, rich in description and meaning — gathered through interviews, observation, and textual analysis. Quantitative data uses numbers and statistics (surveys, experiments). Both are valid; the choice depends on the research question.
Marx identified four types of alienation under capitalism: from the product of labor, from the act of production, from fellow workers, and from one's human potential (species-being). False consciousness is the worker's acceptance of the dominant ideology that serves the ruling class.
Gemeinschaft (community): intimate, personal, traditional — like a small rural village. Gesellschaft (society): impersonal, contractual, goal-oriented — like a modern city. Tönnies saw modernization as a shift from Gemeinschaft to Gesellschaft.
From the conflict perspective, schools don't just teach academic content. They also teach children to obey authority, follow schedules, accept hierarchy, and internalize class-based norms — reinforcing existing social inequalities.
Mead's stages: Preparatory (imitation) → Play stage (taking the role of specific others) → Game stage (understanding multiple roles simultaneously) → Generalized other (internalizing society's expectations). The generalized other is the final stage of full social development.
Role conflict = tension between two different roles one occupies (parent vs. nurse). Role strain = tension within a single role (e.g., a police officer's duty to enforce laws conflicts with community relations). Status inconsistency = holding different ranks on different dimensions.
A wide base means many young people (high birth rate). A rapidly narrowing pyramid indicates high mortality in younger/middle age groups. This is characteristic of developing nations. An inverted or rectangular pyramid suggests low birth rates and an aging population.
Social epidemiology examines how social factors — class, race, gender, neighborhood — affect patterns of health and disease. It consistently finds that lower socioeconomic status is associated with worse health outcomes across nearly all measures.
In The Power Elite (1956), Mills argued that a small, interconnected group of leaders from the military, corporations, and government make the major decisions that shape American society, undermining democratic pluralism.
Anomie (Durkheim, later Merton) refers to a condition where social norms are weakened or absent. Durkheim linked it to rapid industrialization and high suicide rates. Merton adapted it to explain deviance when cultural goals can't be achieved through legitimate means.
The independent variable (IV) is the cause — what the researcher manipulates. The dependent variable (DV) is the effect — what is measured. The control group is not exposed to the IV; the experimental group is. Confounding variables can distort results.
Wirth's sociological definition of minority group emphasizes subordinate status and group consciousness, not numerical size. Women, for example, are a majority numerically but have historically been a "minority group" sociologically.
Disengagement theory (Cumming and Henry) argues that the elderly and society gradually withdraw from each other — a natural and functional process. Contrasted with Activity theory, which argues that remaining active leads to greater life satisfaction.
The Thomas theorem reflects the symbolic interactionist idea that subjective meanings shape social reality. People act on their perceptions, and those actions have real consequences — even if the perceptions are objectively false (e.g., a bank run based on false rumors).
Resocialization involves stripping away an old identity and replacing it with a new one. Boot camp is a classic example — recruits shed civilian identity and adopt military identity. It often occurs in total institutions (Goffman): prison, military, psychiatric facilities.
The Pygmalion Effect (Rosenthal and Jacobson): when teachers expected students to bloom academically, those students performed better. This is a self-fulfilling prophecy — a false belief that, because it's acted upon, becomes true. Rooted in the Thomas theorem and symbolic interactionism.
Patterns of intergroup relations: Pluralism (groups coexist while maintaining distinct identities), Assimilation (minority adopts dominant culture), Segregation (physical/social separation), Amalgamation (biological/cultural blending), Genocide (systematic elimination).
Michels observed that as organizations grow, leadership becomes concentrated in the hands of a few who develop interests in maintaining their power. Even socialist and labor organizations, founded on democratic principles, eventually develop oligarchic structures.
Durkheim (functionalist): religion serves to unite communities through shared rituals and beliefs, creating social solidarity. He saw totemism as the most basic form. Contrast with Marx (opiate of the masses) and Weber (cultural driver of capitalism).
Weber's bureaucracy features: (1) division of labor/specialization, (2) hierarchy of authority, (3) written rules and procedures, (4) impersonality (decisions based on rules, not personal relationships), (5) employment based on technical qualifications — NOT personal loyalty.
Urbanization = rural-to-urban population movement. Suburbanization = city-to-suburb movement. Gentrification = wealthier people move into poorer urban areas, raising property values and often displacing existing residents. Demographic transition = the shift from high to low birth/death rates with industrialization.
Correlation does not imply causation. A spurious relationship exists when a third variable (e.g., poverty) causes both the increase in fast food restaurants and the rise in obesity rates, making the two appear correlated when there is no direct causal link.
Relative deprivation: feeling disadvantaged compared to a reference group, even if one's absolute conditions are adequate. A person earning $50k may feel deprived if their peers earn $100k. Used to explain social movements — people mobilize when they feel they deserve more relative to others.
Endogamy = marriage within your social group (same religion, caste, ethnicity). Exogamy = marriage outside your group. Caste systems typically enforce endogamy. Patrilocal = living with husband's family; matrilocal = living with wife's family.
Medicalization: the expansion of medical jurisdiction into areas previously seen as moral, religious, or legal issues. Examples: alcoholism (once a moral failure, now an addiction disorder), ADHD, obesity. Critics argue this depoliticizes social problems and increases pharmaceutical industry influence.
Intragenerational mobility = change in class position within one's own lifetime. Intergenerational mobility = change between parent and child. Upward vs. downward refers to direction. Horizontal mobility = moving to a similar-status position. Structural mobility = caused by economic shifts, not individual effort.
Conflict theory (Marx, Weber, Mills) sees stratification as the result of struggle between groups with competing interests. The powerful maintain their position through economic control, laws, ideology, and force. Option A is the functionalist view (Davis-Moore thesis). Options B and D reflect individualist perspectives.
The Gini coefficient is derived from the Lorenz curve. A coefficient of 0 means everyone has identical income; a coefficient of 1 means one person has all the income. The United States has a Gini around 0.39–0.41, higher than most other wealthy nations.
Sutherland's theory holds that crime is learned through social interaction, especially in close relationships. Learning includes techniques, motives, rationalizations, and attitudes. The key concept is the ratio of definitions: if a person encounters more pro-criminal than anti-criminal attitudes, criminal behavior is likely.
Ritzer extended Weber's rationalization thesis. McDonaldization's four dimensions are: efficiency (optimal method), calculability (emphasis on quantity), predictability (standardized outcomes), and control (via technology). He argues this leads to an "iron cage" of rationality that strips human creativity and spontaneity.
Resource mobilization theory (McCarthy and Zald) shifts focus from grievances (which are always present) to organizational capacity. Movements need money, labor, media access, and alliances to succeed. This explains why some aggrieved groups form effective movements while others do not.
A reference group is any group used as a standard for self-evaluation, whether or not the person is a member. For example, a working-class student who compares themselves to college-educated professionals uses that group as a reference group. This concept is closely tied to relative deprivation.
Groupthink symptoms include illusion of invulnerability, collective rationalization, belief in the group's morality, stereotyped views of out-groups, pressure on dissenters, and self-censorship. Classic examples: the Bay of Pigs invasion, the Challenger disaster. Prevention includes assigning devil's advocates.
In world-systems theory, core nations (U.S., Western Europe, Japan) exploit peripheral nations (much of Africa, parts of Latin America/Asia) by extracting cheap labor and raw materials. Semi-peripheral nations (Brazil, India, China) occupy an intermediate position. This is a conflict-theory approach to global inequality.
The four stages: (1) pre-industrial: high births, high deaths; (2) early industrial: high births, falling deaths → population explosion; (3) late industrial: falling births, low deaths; (4) post-industrial: low births, low deaths → stable or declining population. This model helps demographers predict population growth.
"They all look the same" is the colloquial expression of this bias. People perceive their own group (in-group) as diverse and complex, but see out-group members as a homogeneous mass. This cognitive bias fuels stereotyping and contributes to prejudice and discrimination.
Framing theory holds that movements must "frame" their cause effectively: diagnosing the problem, proposing solutions, and motivating action. Frames must resonate with the target audience's values. For example, the civil rights movement framed segregation as a violation of core American ideals of equality and justice.
Collective behavior refers to relatively spontaneous, unorganized, and unpredictable social action — crowds, mobs, panics, fads, crazes, and rumors. Social movements, by contrast, are organized, goal-directed, and sustained over time. Smelser's value-added theory identifies structural conduciveness, strain, and precipitating events as conditions for collective behavior.
Goffman identified five types of total institutions: (1) for the incapable and harmless (nursing homes), (2) for those seen as threats (mental hospitals), (3) for those posing intentional threats (prisons), (4) for instrumental tasks (military barracks), (5) for retreats (monasteries). All involve stripping inmates of their prior identity (mortification of self).
Sexism is prejudice and discrimination based on gender, often rooted in beliefs about biological inferiority. Patriarchy refers to a social system of male dominance in institutions and structures. Androcentrism is the centering of male perspectives as the norm. Misogyny is a specific hatred of women. All are related but distinct concepts.
Ageism (Robert Butler) involves stereotypes, prejudice, and discrimination against people based on their age. Like racism and sexism, it can be institutional or individual. Common manifestations: forced retirement, condescending treatment, exclusion from healthcare decisions, and underrepresentation in media. The Age Discrimination in Employment Act (1967) addresses some forms.
The social model (developed by disability rights scholars and activists) distinguishes between impairment (a physical/cognitive difference) and disability (the social barriers that prevent full participation). Stairs disable wheelchair users; the problem is not the wheelchair but the lack of ramps. This model underpins the Americans with Disabilities Act (1990).
Media (television, social media, film) shapes perceptions of what is normal, desirable, and appropriate. It reinforces gender roles, racial stereotypes, consumption values, and political orientations. While it transmits dominant values, audiences also resist and reinterpret messages (Hall's encoding/decoding model).
Polygamy has two forms: polygyny (one husband, multiple wives — the most common form historically and cross-culturally) and polyandry (one wife, multiple husbands — rare). Serial monogamy — marrying, divorcing, and remarrying — is common in contemporary Western societies. Most societies worldwide permit polygyny, though monogamy is most widely practiced.
The rise in divorce reflects multiple structural changes: no-fault divorce laws reduced legal barriers; women's labor force participation gave women financial independence; and cultural norms shifted to prioritize individual fulfillment over marital stability. Sociologists do not view rising divorce as purely negative — it may reflect the deinstitutionalization of marriage (Cherlin).
Credential inflation (Randall Collins) occurs when positions require higher levels of education over time, not because jobs have become more complex, but because employers use credentials as sorting mechanisms. This disadvantages lower-class individuals who face greater barriers to obtaining credentials and reinforces class reproduction.
The treadmill of production theory holds that the logic of capitalism requires constant economic expansion, which continuously draws on natural resources and generates waste. Because economic growth is politically and socially rewarded, actors are locked into patterns of environmental harm even when aware of consequences. This is a foundational concept in environmental sociology.
Mollie Orshansky developed the official U.S. poverty threshold in the 1960s by calculating the minimum cost of a nutritious diet and multiplying by three (since the average family spent about one-third of income on food). Critics note this method is outdated — housing, childcare, and healthcare now consume much larger shares of income.
Structural racism includes historical policies (redlining, exclusion from GI Bill benefits, discriminatory lending) and ongoing institutional practices (disparities in criminal sentencing, school funding tied to property taxes) that maintain racial disparities in wealth, health, education, and political power without requiring individual racist intent.
Secondary data analysis uses existing data — government records, historical documents, prior survey datasets, administrative records — rather than collecting new data. Advantages: cost efficiency, large sample sizes, historical reach. Disadvantages: no control over how data was originally collected, potential measurement issues, and limited variables.
Blended families have become increasingly common with rising divorce and remarriage rates. They present unique sociological dynamics: stepparent-stepchild relationships, half-siblings, competing loyalties, and redefining family boundaries. Sociologists note that family structure is increasingly diverse, with no single "normal" form.
Surveys are the most commonly used method in sociology. Key concepts: population (the group of interest), sample (a subset), random sampling (each member has an equal chance of selection — improves representativeness), and response rate. Surveys excel at reaching large numbers efficiently but are limited by respondents' honesty and recall.
Net migration rate = (immigrants − emigrants) / population × 1,000. A positive rate means more people entering than leaving; a negative rate means more are leaving. Along with birth rate and death rate, net migration is a key component of population change. Many developed nations rely on positive net migration to offset low birth rates.
The social gradient in health shows a consistent, stepwise relationship between socioeconomic status and health. Lower SES is linked to greater exposure to environmental hazards, chronic stress, poorer nutrition, less access to healthcare, and lower health literacy. This relationship persists even in countries with universal healthcare, pointing to fundamental causes beyond access alone (Link and Phelan).
Intergenerational mobility refers to changes in social class position between parent and child (across generations). Option A illustrates intragenerational upward mobility (within a lifetime). Option B illustrates horizontal mobility (same level, different job). Research shows the United States has lower intergenerational mobility than many European nations — meaning parental class strongly predicts children's outcomes.
Secondary deviance (Lemert, elaborated by Becker) occurs when a person accepts and acts upon a deviant label, reorganizing their identity around it. The labeling process itself — criminal record, social stigma, reduced opportunities — can drive people deeper into deviant careers, creating a self-fulfilling prophecy. This critique targets how the criminal justice system may amplify, rather than reduce, deviance.
Conflict theorists (Marx, Quinney) argue that laws are made by the powerful to protect their interests. The criminal justice system selectively enforces laws in ways that disadvantage the poor and racial minorities. Evidence includes disparities in drug sentencing (crack vs. powder cocaine), racially biased policing (stop-and-frisk), and white-collar crime receiving lighter penalties than street crime.
Cohen's moral panic concept (from Folk Devils and Moral Panics, 1972) identifies a cycle: media exaggerates a threat, public anxiety rises, authorities respond with crackdowns, often targeting a vulnerable group. Historic examples: fear of "dangerous" youth subcultures, satanic panic in the 1980s, recent panics about immigration. Media amplification and expert "moral entrepreneurs" are key to the process.
The nuclear family (also called the conjugal family) became the normative American family form in the post-WWII era. Functionalists (Parsons) argued it serves society through socialization of children (expressive role) and earning income (instrumental role). However, the nuclear family is now less dominant as cohabitation, single-parent households, and same-sex families have become more prevalent.
Durkheim's most fundamental religious concept is the division between the sacred (set apart, commanding reverence, connected to the collective) and the profane (the ordinary world). Religion consists of beliefs and practices relating to sacred things that unite believers into a moral community (church). Collective effervescence refers to the emotional energy generated during group rituals.
The secularization thesis holds that as societies modernize, religion loses influence over public institutions (law, education, politics) and private belief. Evidence includes declining church attendance in Western Europe. However, the United States and much of the Global South remain highly religious, leading some scholars (Berger) to revise or reject the thesis in favor of religious pluralism models.
A ritualist abandons the cultural goal of success but continues to follow the rules mechanically (e.g., a bureaucrat who follows procedures even when it serves no purpose). This is different from a retreatist who abandons both goals and means, and from an innovator who accepts goals but uses illegitimate means. The ritualist represents a kind of "going through the motions."
Double-blind designs prevent both demand characteristics (participants behave according to expectations) and researcher bias (researchers unconsciously influence results). Common in medical trials (neither patient nor clinician knows if patient received drug or placebo). Single-blind = only participants are unaware. This method strengthens internal validity.
Diana Pearce coined the term in 1978 to describe how women — especially female-headed single-parent households — are overrepresented among the poor. Explanations include the gender wage gap, occupational segregation, the unpaid labor of caregiving, inadequate childcare, and the breakdown of the breadwinner-homemaker family model.
Mills' sociological imagination requires seeing personal troubles (one person unemployed) as connected to public issues (millions unemployed due to economic recession). The distinction reframes individual suffering as symptoms of larger social structures. This perspective is foundational to sociological analysis and shapes how sociologists define social problems.
Davis and Moore argued stratification is a universal mechanism ensuring the most talented fill the most important roles by offering high rewards. Critics (Tumin) note: (1) we cannot objectively measure "functional importance"; (2) the system does not ensure the most talented reach top positions — wealth, connections, and inheritance determine access; (3) dysfunctions of inequality (wasted talent, resentment) are ignored.
Status inconsistency refers to the gap between different stratification dimensions. Example: a highly educated professor who earns a modest salary (high education, low income) or a wealthy drug dealer (high income, low occupational prestige). Lenski argued that status inconsistency creates psychological stress and is associated with political liberalism as affected individuals seek systemic change.
The extended family is the predominant family form in many non-Western and less-industrialized societies. In the United States, extended family households are more common among immigrant families, lower-income families (for economic support), and many racial/ethnic minority communities. Extended families provide a broader support network but may also involve complex household dynamics.
Political process theory (McAdam, Tarrow, Tilly) focuses on macropolitical conditions that enable or impede movements: openness of the political system, presence of elite allies, stability of ruling alignments, and state capacity for repression. Unlike resource mobilization (which focuses on internal organizational capacity), this approach emphasizes the external political context.
Fads are a form of collective behavior characterized by rapid adoption, widespread enthusiasm, and equally rapid decline (e.g., fidget spinners, pet rocks, ice bucket challenge). Unlike fashion, which moves in slower cycles, fads are especially intense and short-lived. Like fashions, fads serve social functions — creating group identity and novelty. They are distinct from social trends, which represent more enduring changes.
Media consolidation is the process by which ownership of media outlets becomes concentrated in fewer corporate hands. Critics argue this limits diversity of viewpoints, undermines democratic discourse, and promotes corporate interests over the public good. The FCC regulates media ownership in the U.S., but consolidation has accelerated since the Telecommunications Act of 1996.
Bellah argued that the United States has a civil religion — a shared set of beliefs and practices (the pledge of allegiance, national holidays, monuments, presidential inaugurations invoking God) that function sociologically like religion. It provides transcendent meaning, national solidarity, and moral guidance without being tied to a specific denomination. This is a Durkheimian analysis applied to the American nation-state.
This is a classic illustration of a spurious correlation — a statistical relationship between two variables that is actually caused by a third variable. In sociological research, failing to account for confounding variables leads to false causal claims. Establishing causation requires: (1) correlation, (2) temporal order (cause precedes effect), and (3) elimination of alternative explanations.
"Face" refers to the positive social value a person claims in interaction. Face-work includes tact, apologies, and rituals to prevent embarrassment and protect both one's own and others' self-image. This is part of Goffman's interaction ritual theory and illustrates the micro-level social work required to sustain the fabric of everyday life.
Structural mobility occurs at the macro level when large-scale economic changes create or eliminate job categories. For example, the post-WWII American economic boom created millions of middle-class jobs, enabling upward mobility for many. Conversely, deindustrialization caused structural downward mobility for manufacturing workers. This is distinct from circulation mobility (exchange mobility), which involves individual movement within a stable structure.
Exogamy requires marrying outside a defined group — clan, lineage, or family. The near-universal incest taboo is the most fundamental form of exogamy. Anthropologists have offered multiple explanations: preventing genetic defects (biological), reducing family conflict (psychological), and forcing alliances between groups through marriage exchange (social/structural — Lévi-Strauss). Options A, B, and D are examples of endogamy.
Environmental racism (Robert Bullard, "Dumping in Dixie") documents how communities of color and low-income communities bear a disproportionate burden of pollution, toxic waste sites, and environmental health hazards. This is both a cause and consequence of racial inequality. The environmental justice movement emerged to challenge these disparities and demand equitable enforcement of environmental regulations.
Davis and Moore (1945) argued stratification is a universal and functional necessity: society must fill all positions, some positions are more important and require scarce talent, so higher rewards are offered to attract qualified people. Tumin's critique: it's circular (how do we know which positions are most important?), it ignores ascriptive barriers, and it ignores the dysfunctions of inequality. Conflict theorists argue stratification serves the interests of elites, not society as a whole.
Intergenerational mobility compares the social class of parents to that of their adult children — the classic measure of a society's openness. Intragenerational (career) mobility tracks an individual's own mobility over their lifetime. Research shows the U.S. has less intergenerational mobility than many Western European nations. The correlation between parent and child income (intergenerational earnings elasticity) is higher in the U.S. than in Canada or Scandinavia.
Caste systems are closed stratification systems: position is ascribed by birth, endogamy (marriage within caste) is enforced, and there is minimal opportunity for mobility. Class systems are more open: position is partly achieved, exogamy is permitted, and mobility is possible. India's traditional caste system (Brahmin, Kshatriya, Vaishya, Shudra, Dalits) is the most studied example. The apartheid system in South Africa was another form of rigid racial caste stratification.
Institutional racism (Stokely Carmichael and Charles Hamilton, 1967) operates through organizational policies and practices — not necessarily through the prejudice of individuals. Examples: racially discriminatory lending (redlining), school funding based on property taxes (concentrating resources in wealthier, often whiter, areas), and disparate enforcement of drug laws. This is distinct from individual (interpersonal) racism. The concept is important because it explains racial disparities without requiring individual racist intent.
De jure (Latin: "by law") segregation is legally mandated separation by race — exemplified by the Jim Crow laws in the American South after Reconstruction. De facto ("in fact") segregation exists in practice without legal requirement, often resulting from residential patterns, economic inequality, and historical discrimination. The Supreme Court struck down de jure school segregation in Brown v. Board of Education (1954), but de facto segregation in schools persists in many areas today.
This distinction is foundational in gender sociology: sex = biological (chromosomes, hormones, reproductive anatomy); gender = social and cultural (roles, norms, identities assigned to sexes). Gender varies across cultures and historical periods — what is "masculine" or "feminine" is not universal. Evidence: Margaret Mead's cross-cultural research on gender roles (Arapesh, Mundugumor, Tchambuli) showed dramatic variation. The constructionist view holds that gender is "performed" (Butler) rather than inherent.
The glass ceiling (first used in a 1986 Wall Street Journal article) describes barriers that are invisible (not explicit policies) but real in effect. Research shows women are underrepresented at the top of organizations across sectors, even controlling for qualifications and experience. Related concepts: the "glass escalator" (men in female-dominated professions rise quickly), the "sticky floor" (women trapped in low-wage jobs), and "maternal wall" (penalties for motherhood). The "glass cliff" is the phenomenon of women being appointed to leadership in organizations in crisis.
Feminist waves: First wave (late 19th–early 20th century) — suffrage, property rights, legal personhood (Seneca Falls 1848, 19th Amendment 1920). Second wave (1960s–1980s) — NOW, ERA, Title IX, Roe v. Wade, Betty Friedan's "Feminine Mystique," Gloria Steinem; addressed workplace discrimination, reproductive rights, domestic violence. Third wave (1990s–2000s) — intersectionality, embracing diversity within feminism, media critique. Fourth wave (2010s–present) — social media activism, #MeToo movement.
Sutherland's differential association theory (1939): criminal behavior is learned, not inherited or invented; learning occurs within intimate personal groups; learning includes techniques of committing crime AND favorable attitudes toward crime; a person becomes criminal when definitions favorable to violation outnumber unfavorable ones. Key implication: hanging out with law-breakers increases the likelihood of becoming one. This theory applies to white-collar crime as well as street crime.
Wilson and Kelling argued that visible signs of disorder (broken windows, graffiti, litter) signal that social control has broken down, inviting more serious crime. Policy implication: "zero-tolerance" policing of minor offenses (famously applied in NYC in the 1990s). Criticisms: the crime drop may have had other causes (demographics, economy, lead removal); zero-tolerance policing has been associated with racial profiling and mass incarceration; empirical support is mixed.
Research consistently shows that marrying at a later age is associated with lower divorce risk. The other three factors all contributed to rising divorce rates: women's labor force participation gave economic independence; no-fault divorce laws (1970 California first) removed legal barriers; and cultural secularization reduced the social stigma of divorce. Since the 1980s, divorce rates have actually declined among the college-educated (who also tend to marry later), while rising among less-educated groups — contributing to growing class divergence in family structure.
Blended families (stepfamilies) have become increasingly common due to high divorce and remarriage rates. They present unique sociological challenges: role ambiguity (what does "stepparent" mean?), loyalty conflicts for children, competing claims on resources, and complex extended kin networks. Research shows children in stepfamilies have somewhat worse outcomes on average than those in intact two-parent families, but family process variables (conflict, warmth, economic resources) matter more than structure alone.
The secularization thesis (Weber, Berger, Wilson) predicts that modernization — science, rationalization, differentiation of social institutions — leads to declining religious belief and practice. Evidence: Europe shows dramatic decline. Counter-evidence: the U.S. remains highly religious despite being modern; global religiosity is not declining overall; Berger himself later revised his thesis. "Desecularization" theorists argue religion is actually reviving globally. The U.S. case is debated as a major exception to the thesis.
Bellah (1967) argued the U.S. has a "civil religion" — a set of beliefs, symbols, and rituals that give America sacred meaning, transcending any particular denomination. Elements: sacred texts (Declaration, Constitution), prophets (Founding Fathers, Lincoln), martyrs (Lincoln, Kennedy), holy days (July 4th, Memorial Day), sacred places (memorials, battlefields). This functions to integrate a religiously diverse nation. Durkheim's insight: all societies need something sacred to bind them; in modern nations, the nation itself can serve this function.
In "The Elementary Forms of Religious Life" (1912), Durkheim argued that religion's ultimate object of worship is society itself — the sacred represents the collective. Religious rituals (totemism, ceremonies) serve to reinforce group identity and solidarity, remind members of their interdependence, and recharge commitment to collective values. When people worship God, they are symbolically worshipping society. Marx by contrast saw religion as ideology masking class interests ("opium of the people"); Weber emphasized religion's role in cultural change (Protestant Ethic).
The hidden curriculum (Philip Jackson, "Life in Classrooms," 1968) refers to what students learn beyond the formal curriculum: punctuality, following instructions, sitting quietly, competition, respect for authority, gender norms. Conflict theorists (Bowles and Gintis) argue the hidden curriculum reproduces capitalist social relations by socializing working-class kids to accept hierarchy and discipline. Related concept: credentialism — the increasing requirement of formal educational credentials for jobs, regardless of whether skills are actually learned.
Tracking assigns students to college-prep, general, or vocational tracks based on perceived ability. Sociological research shows tracking tends to reproduce inequality: lower-track students receive watered-down curricula, less-experienced teachers, and lower teacher expectations. Since track placement correlates with race and class, tracking can perpetuate stratification. Jeannie Oakes ("Keeping Track") documented these effects extensively. Proponents argue tracking allows teachers to calibrate instruction; critics argue it creates self-fulfilling prophecies and denies equal educational opportunity.
Gustave Le Bon ("The Crowd," 1895) argued that in crowds, individuals undergo a transformation: anonymity causes loss of individual identity, emotional contagion spreads feelings rapidly, and suggestibility increases. The result is "group mind" — irrational, emotional, and capable of violence. Critics: empirical research shows crowd behavior is more rational and purposeful than Le Bon suggested. Turner and Killian's emergent norm theory proposes that crowd behavior follows new norms that emerge during collective situations, not mindless contagion.
Resource mobilization theory (McCarthy and Zald, 1977) shifted focus from grievances (which are abundant) to resources: organizations, money, members, media access, and political allies. Key insight: many grievances exist but few produce movements — the difference is organizational capacity. Movements need SMOs (social movement organizations) to coordinate action. Critique: ignores cultural and emotional dimensions; political process/opportunity theory adds the importance of the political context and available openings for change.
Wallerstein's world-systems theory: Core nations (U.S., Western Europe, Japan) control high-skill, capital-intensive production and extract surplus from the periphery. Periphery nations (many in Africa, parts of Asia and Latin America) provide raw materials and cheap labor. Semi-periphery nations (Brazil, India, China) are in between. Core nations dominate international financial institutions. This is a structural theory — it argues poor nations are poor not because of internal failings (as modernization theory suggests) but because the system is structured to keep them that way.
Frank's dependency theory challenged modernization theory: poor nations are not simply at an earlier stage of development. They were actively underdeveloped through colonialism and neo-colonialism — forced to specialize in primary commodities, integrate into a global economy on unfavorable terms, and remain dependent on wealthy "metropole" nations. The profits from periphery labor flow to core nations, leaving the periphery poor. Policy implication: Third World nations should pursue inward-oriented development, not rely on foreign investment and trade with the core.
Modernization theory (Rostow's "Stages of Economic Growth," 1960) argues all societies progress through the same stages: traditional society → preconditions for takeoff → takeoff → drive to maturity → high mass consumption. Developing nations need capital investment, Western technology, and cultural modernization (Protestant-style work ethic, rational institutions). Critics: ethnocentric (assumes Western path is universal), ignores structural barriers, and ignores that colonialism created the conditions it blames on culture. Dependency and world-systems theories emerged as direct critiques.
Malthus ("An Essay on the Principle of Population," 1798): population has a tendency to outrun food supply. "Positive checks" (famine, disease, war) and "preventive checks" (delayed marriage, celibacy) hold population in check. Neo-Malthusians apply this to modern resource scarcity. Critics: the Green Revolution dramatically increased food production; demographic transition theory shows that as nations develop, birth rates fall; technology and social organization can overcome Malthusian limits. Still influential in environmental sociology and sustainability debates.
The demographic transition (Warren Thompson, 1929): Stage 1 (pre-industrial) — high births, high deaths, stable population. Stage 2 (early industrial) — death rates fall (medicine, sanitation) but birth rates remain high → population explosion. Stage 3 (mature industrial) — birth rates fall as urbanization, education, and women's roles change. Stage 4 (post-industrial) — low births, low deaths, stable or declining population. Many developed nations are in Stage 4 or a proposed Stage 5 (sub-replacement fertility). Most developing nations are in Stage 2 or 3.
Urbanization involves both demographic shifts (population moving to cities) and social transformations. Tönnies: rural Gemeinschaft (community — close, personal, traditional) vs. urban Gesellschaft (society — impersonal, contractual, diverse). Simmel ("The Metropolis and Mental Life"): urban life creates a blasé attitude as psychological defense against overstimulation. Wirth's urbanism: city life characterized by size, density, and heterogeneity produces weakened primary ties, anonymity, and formal social control. Today more than half the world's population lives in urban areas.
Operationalization translates abstract theoretical concepts into concrete, measurable variables. Example: "social class" could be operationalized as annual income, or as education level, or as self-identified class — each operationalization captures different aspects. A good operationalization should be both reliable (consistent measurements) and valid (actually measuring what it claims to measure). Different operationalizations of the same concept can yield different findings, which is why replication and conceptual clarity are crucial in social science research.
Reliability = consistency (the same result each time). Validity = accuracy (measuring what you intend). A bathroom scale that always reads 10 pounds too heavy is reliable (consistent) but not valid (inaccurate). A valid measure must be reliable, but a reliable measure need not be valid. In sociology: measuring "intelligence" with a scale that consistently gives the same score is reliable; if that score only reflects test-taking skills, not general cognitive ability, it lacks validity. Construct validity, content validity, and criterion validity are all types of validity.
The Hawthorne effect emerged from studies at the Hawthorne Works factory (1920s–1930s): worker productivity improved regardless of which changes were made to working conditions, apparently because workers knew they were being observed. This became a fundamental concern for social science research — observation itself can alter behavior. Methods to address this: unobtrusive observation, habituation (letting participants get used to the researcher's presence), and using existing data (content analysis, official statistics) rather than direct observation.
Peggy McIntosh's "Invisible Knapsack" (1989) popularized the concept: white privilege consists of daily, unearned advantages that white people take for granted — being able to shop without being followed, seeing one's race positively portrayed in media, not being asked to speak for one's entire race. Important distinction: privilege ≠ having an easy life; it means not facing specific racial barriers. Intersectionality (Crenshaw) notes that privilege and disadvantage can coexist — a Black man may have male privilege but lack white privilege.
Sociologists classify social movements by scope and direction: Reform movements seek partial change within existing institutions (Civil Rights Movement, labor movement, suffrage movement). Revolutionary movements seek complete transformation of the social order (Bolshevik Revolution, Chinese Revolution). Reactionary (counter/regressive) movements seek to reverse change and return to an earlier order. Alternative (redemptive) movements target individuals rather than society (Alcoholics Anonymous, religious conversion movements). Resistance movements oppose specific changes.
Cohabitation (unmarried couples living together) has increased dramatically: from about 450,000 couples in 1960 to over 8 million today. Research shows cohabitation patterns vary by class: for college-educated couples, cohabitation often serves as "trial marriage" leading to marriage; for less-educated couples, cohabitation is less often a precursor to marriage and associated with higher subsequent divorce risk ("cohabitation effect"). Changing social norms, women's economic independence, and delayed marriage all contribute to rising cohabitation rates.
Collins ("The Credential Society," 1979) argues credential inflation occurs independently of actual skill requirements — jobs that once required a high school diploma now require a bachelor's, not because the work changed but because credentials function as social closure (excluding competitors) and status signaling. Evidence: the actual skills used in many jobs are learned on the job, not in school. Credential inflation disadvantages those who cannot afford extended schooling, effectively functioning as a class barrier while appearing meritocratic.
"Global South" is a socioeconomic and political term (not strictly geographic), replacing older terms like "Third World" or "developing world." It encompasses countries that share histories of colonialism, lower per-capita incomes, and less political power in international institutions. Australia and New Zealand are in the Southern Hemisphere but are Global North. It is contrasted with the Global North (wealthy, historically dominant nations). The term avoids the developmental bias of "developing" (implying they are simply "behind") and the Cold War framing of "Third World."
Social institutions are stable clusters of norms, values, statuses, and roles that address fundamental social needs. The major institutions: family (reproduction, socialization), education (transmission of knowledge), religion (meaning, cohesion), economy (production and distribution), polity/government (order, power). Institutions are not buildings or organizations — "the institution of marriage" is the set of norms and expectations around marriage, not City Hall. Functionalists see institutions as meeting social needs; conflict theorists see them as reflecting and reinforcing power inequalities.
Durkheim introduced anomie in "The Division of Labor in Society" and developed it in "Suicide": rapid social change — industrialization, economic booms or busts — can disrupt the normative framework that regulates social life, leaving individuals without clear guidelines (anomie). Anomic suicide results from insufficient social regulation. Merton later adapted the concept differently: for Merton, anomie is the gap between culturally valued goals and the legitimate means to reach them. Both uses are common in sociology; context determines which usage is meant.
Crenshaw (1989, 1991) coined the term to explain why Black women's experiences of discrimination were not captured by either race discrimination law or sex discrimination law — their specific position at the intersection of both categories created unique vulnerabilities. Intersectionality has since been applied broadly: a wealthy white woman and a poor Black woman have very different experiences of gender, making "women" too broad a category for analysis. Similarly with "Black Americans" obscuring class differences. This became foundational to third-wave feminism and contemporary social justice frameworks.
William Graham Sumner coined both terms. Folkways: informal everyday norms — dressing appropriately for occasions, greeting people, table manners. Violations produce mild sanctions (embarrassment, disapproval). Mores: norms tied to core values of right and wrong — prohibitions on murder, incest, betrayal. Violations produce strong sanctions (ostracism, criminal prosecution). Taboos are the most extreme mores. Laws are formalized mores enforced by the state. This hierarchy — folkways → mores → taboos → laws — reflects the intensity of social reactions to violations.
A spurious correlation is a statistical relationship between two variables that is caused by a third variable (the confound), not a direct causal link. Here, population density (urbanization) causes both more Starbucks (more customers) and more lung cancer cases (more people). Correlation ≠ causation — establishing causation requires: correlation, temporal order (cause precedes effect), and elimination of alternative explanations. This is fundamental to research methods: always look for potential confounding variables before claiming a causal relationship.
Simmel's formal sociology analyzed group forms abstractly. The dyad is unique: it depends entirely on both individuals — there is no "group" that can survive either member's departure. The triad changes this fundamentally: a third party can mediate conflicts, form coalitions with either other member against the third, or divide and conquer. This transforms the social dynamic from purely personal to something with a group life of its own. Simmel's point: social forms matter — the same content (friendship, business) feels different in dyad vs. triad.
Ascribed statuses are assigned without choice: race, sex, age, family of origin, caste. Achieved statuses are earned through actions: college graduate, doctor, criminal, champion. Master status: the status that overrides all others in shaping social interactions (race is often a master status in the U.S.; disability frequently becomes a master status). Modern societies ideally emphasize achieved over ascribed status (meritocracy ideal), but ascribed characteristics continue to strongly shape life chances — as research on racial and gender gaps in hiring, wages, and other outcomes demonstrates.
Zimbardo randomly assigned college students to "guard" or "prisoner" roles in a simulated prison. Within days, guards became abusive and prisoners became submissive/depressed — the experiment was stopped after 6 days (of a planned 2 weeks). Lesson: situations, not just personalities, shape behavior. Connects to Milgram's obedience studies (situational authority) and to Goffman's total institutions. Ethical criticisms: lack of informed consent, physical/psychological harm. Recent critics (Le Texier) argue the study was more scripted than reported — Zimbardo coached the guards.
W.I. Thomas (1928): our subjective definition of a situation shapes our behavior, which then has real consequences — regardless of whether the definition is objectively accurate. Example: if people believe a bank is failing and rush to withdraw (bank run), the bank actually fails. Connects to: the self-fulfilling prophecy (Merton), teacher expectations (Pygmalion effect), and symbolic interactionism's emphasis on subjective meaning. Foundational for understanding how stereotypes, racial classifications, and social labels have real effects even when not "objectively" real.
The sandwich generation (Dorothy Miller, 1981) describes middle-aged adults (typically 40s–50s) squeezed between caring for dependent children and aging parents who need assistance. Women disproportionately bear these dual caregiving burdens. Sociologically relevant to: the feminization of caregiving labor, work-family conflict, the aging of the Baby Boom cohort, and eldercare policy. As life expectancy increases and birth rates decline, the proportion of adults in this position grows. Related to Hochschild's "second shift" — the unpaid domestic and care work that falls primarily to women.
Weber argued that social science must go beyond identifying external regularities (positivism) to understand the subjective meaning actors give to their behavior — Verstehen (German: understanding). Unlike natural science objects, humans act based on meanings, intentions, and interpretations. A funeral and a party may involve the same physical behaviors; only understanding their meaning distinguishes them. Weber combined this interpretive approach with causal explanation — making sociology both humanistic and scientific. This underpins qualitative methods (interviews, ethnography) that seek to understand participants' perspectives.
Prejudice: a negative attitude toward members of a group, based on their group membership (pre-judgment). Discrimination: unequal treatment of individuals based on group membership. They do not always go together: Robert Merton's typology — "active bigot" (prejudiced + discriminates), "timid bigot" (prejudiced, does not discriminate — fear of sanctions), "fair-weather liberal" (not prejudiced, but discriminates — e.g., goes along with discriminatory workplace norms), "all-weather liberal" (neither prejudiced nor discriminating). Structural discrimination can occur without individual prejudice.
The Sapir-Whorf hypothesis: language is not merely a tool for expressing thoughts — it shapes thought itself. Strong version (linguistic determinism): language determines thought; weak version (linguistic relativity): language influences thought and perception. Sociological application: the words available in a culture reflect and reinforce cultural values. George Orwell's "Newspeak" in 1984 dramatizes the political implications. Contemporary research supports the weak version: speakers of languages without spatial terms like "left/right" navigate differently; color vocabulary affects color perception speed.
Robert Merton (1968) coined "Matthew effect" from Matthew 25:29: "For to everyone who has, more will be given, and he will have abundance; but from him who does not have, even what he has will be taken away." In academic citation: famous scientists get disproportionate credit for collaborative discoveries. More broadly: early educational advantages compound through better schools, social networks, and opportunities. Cumulative advantage explains why small early differences (family wealth, school quality) produce large outcome gaps over time — central to understanding persistent inequality.
Goffman ("Asylums," 1961) identified total institutions: prisons, mental hospitals, military boot camps, monasteries, boarding schools. Key features: (1) all activities in one place under one authority, (2) daily activities carried out in the company of others in identical situations, (3) activities tightly scheduled, (4) all activities serve an overarching aim of the institution. Inmates undergo "mortification of self" — stripping of identity, issuing of uniforms, regimentation — and must learn to manage dual identities: official and unofficial selves.
Putnam's social capital (building on Bourdieu and Coleman): bonding social capital (ties within homogeneous groups — strong, but can create in-group/out-group divisions) vs. bridging social capital (ties across diverse groups — weaker but broader reach). Putnam's "Bowling Alone" (2000) argued American social capital declined in late 20th century (less civic participation, fewer social club memberships). High social capital communities show better health outcomes, lower crime, and more effective democratic institutions. Contrast with Bourdieu's cultural capital (tastes, knowledge, credentials that signal class position).
Resocialization involves a fundamental transformation of identity and values — not just learning new things, but replacing a prior self. Examples: military basic training (civilian identity → soldier identity), religious conversion, joining a cult, prison, or recovery programs. Total institutions (Goffman) are primary sites of resocialization because they control the entire environment. The process typically involves stripping away the old identity (mortification) and building a new one through the institution's norms and roles. Voluntary resocialization (joining a monastery) differs from coercive resocialization (imprisonment).
Mead's symbolic interactionist theory of the self (Mind, Self, and Society, 1934): the self is a social product that arises through interaction. The "me" = organized set of attitudes of others which the individual assumes — the internalized generalized other, giving the self its social character and normative constraint. The "I" = the response of the organism to the attitudes of others — the active, novel, creative aspect that can never be fully predicted or controlled. The ongoing conversation between "I" and "me" constitutes the self. Example: you plan what to say at a party (me — anticipating others' expectations) but when you actually speak, something unexpected comes out (I). Social change is possible because the "I" can resist or transform social norms.
Cooley's three-step process (Human Nature and the Social Order, 1902): (1) we imagine how we appear to others in a given situation; (2) we imagine the judgment others make of that appearance; (3) we develop an emotional response (pride if we imagine positive judgment, shame if negative). Crucially, the "mirror" is our imagination of others' perceptions — not necessarily accurate. A person who mistakenly believes others view them positively will develop high self-esteem based on that misperception. This theory contrasts with purely psychological accounts of self that ignore social input. Applied example: a student who believes classmates view them as intelligent (even if not) will develop a confident academic self-concept. Cooley saw society and the individual as inseparable — neither exists without the other.
Goffman's dramaturgical model (The Presentation of Self in Everyday Life, 1959): social life = theatrical performance. Front stage: region where the performance is given to an audience; actors manage impressions using props, costumes, and scripts to present a desired identity. Back stage: region inaccessible to the audience where actors can drop the performance, rehearse, relax, and contradict the front-stage persona. Examples: a restaurant kitchen (backstage) vs. dining room (front stage); a teacher's lounge vs. the classroom; a doctor's private office vs. the exam room. Back-stage behavior often reveals the "real" self or shows preparation efforts that would undermine the front-stage impression if seen. The concept of "audience segregation" (keeping different audiences separate) is related — the same person may present entirely different selves to different audiences.
Granovetter (1973, "The Strength of Weak Ties"): strong ties (close friends, family) tend to know each other and share overlapping information — their networks are dense and redundant. Weak ties (acquaintances) are bridges between otherwise disconnected network clusters — they carry novel, non-redundant information. Job-finding study: people who found jobs through social contacts most often found them through acquaintances, not close friends. Structural holes (Burt, extending Granovetter): positions that bridge otherwise disconnected groups offer "brokerage" advantages. Network density vs. network reach tradeoff: dense networks offer solidarity and trust (bonding capital); sparse, wide networks offer diverse information access (bridging capital). This theory has implications for career mobility, innovation diffusion, and social integration.
Park and Burgess's concentric zone model (Chicago School, 1925): Zone I (CBD) → Zone II (zone in transition: deteriorating housing, light manufacturing, immigrant enclaves, vice districts — subject to invasion by CBD) → Zone III (working-class homes: second-generation immigrants who escaped Zone II) → Zone IV (middle-class residential: single-family homes, better apartments) → Zone V (commuter zone: suburbs, dormitory communities). Invasion-succession process: as CBD expands outward, Zone II deteriorates; immigrants and poor residents who accumulate resources move outward; their old neighborhoods are "invaded" by new waves of migrants. Criticisms: based on early 20th-century Chicago; ignores non-concentric patterns (sector model — Hoyt; multiple nuclei — Harris and Ullman); fails in cities with different historical development patterns (e.g., European cities with wealthy residents near the center).
Gentrification (term coined by Ruth Glass, 1964, observing London): process by which previously disinvested urban neighborhoods attract middle- and upper-class residents, businesses, and capital. Causes: urban amenities (walkability, cultural institutions), lower housing costs relative to suburbs, back-to-the-city movement among educated professionals, municipal policy promoting downtown revival, historic preservation. Effects: rising property taxes and rents → displacement of long-term low-income residents and minority communities; loss of affordable housing stock; neighborhood "upgrading" that may exclude prior residents; cultural displacement (loss of community institutions, businesses serving prior population). Debate: some argue gentrification improves schools, reduces crime, and brings investment; critics emphasize displacement and cultural erasure. Sociologists Neil Smith and Sharon Zukin are key scholars. Edge cities (Garreau): new suburban employment centers that challenge the assumption of a single urban core.
Resource Mobilization Theory (McCarthy and Zald, 1970s): grievances are relatively constant — what varies is the capacity to mobilize. Resources include: money, labor power (volunteers and staff), organizational infrastructure, social network ties, media access, political allies, and cultural legitimacy. Social Movement Organizations (SMOs): formal organizations that pursue movement goals — compete for resources, members, and media attention (the "social movement industry"). Contrast with classical collective behavior theories (Le Bon, Smelser) which emphasized irrationality and grievance; RMT treats social movements as rational, strategic, and organizational. Stages of social movements (Blumer/Mauss): emergence → coalescence → bureaucratization/institutionalization → decline (success, failure, co-optation, repression, or fragmentation). Free rider problem (Olson): why join a movement when you benefit from others' efforts? Selective incentives or coercion needed to motivate participation.
Mancur Olson's "Logic of Collective Action" (1965): public goods (clean air, civil rights, policy changes) are non-excludable — you benefit whether or not you contributed. Rational self-interest suggests: let others bear the costs of activism (time, money, risk) while enjoying the benefits. Solutions to the free rider problem: (1) selective incentives — material or solidary benefits available only to participants (union membership cards, social belonging); (2) coercion — making non-participation costly; (3) small group size — in small groups, individual contributions are more visible and significant; (4) identity and solidarity — when people identify strongly with a cause, participation is intrinsically rewarding. This problem is why many "potential" movements never materialize and why existing movements struggle to expand beyond a committed core.
Allan Schnaiberg (The Environment: From Surplus to Scarcity, 1980): capitalist firms must grow to survive — competitive pressure demands continuous expansion, reinvestment, and increasing throughput of materials and energy. The "treadmill" runs faster as technology enables greater extraction, but the benefits accrue to capital while ecological costs are externalized. Three dialectical contradictions: (1) economic expansion vs. ecological limits; (2) economic rationality (efficiency for profit) vs. ecological rationality (sustainability); (3) capital-labor alliance in production vs. capital-environment conflict. Ecological footprint (Rees and Wackernagel): the land and water area required to produce resources consumed and absorb waste generated. Ecological modernization theory (counterargument): capitalism can be reformed through technology, regulation, and market mechanisms to achieve sustainability — Schnaiberg's critics argue this is possible without abandoning capitalism.
Parsons's sick role (The Social System, 1951) — a functionalist analysis of illness as a social role with four components: Rights: (1) exemption from normal social role responsibilities (work, family duties) commensurate with severity; (2) not held responsible for being ill — illness is not a moral failing. Obligations: (3) must want to get well — illness is inherently temporary and undesirable; (4) must seek technically competent help and cooperate with medical treatment. The sick role legitimizes illness while preventing secondary gain (malingering). Criticisms: (a) assumes all illness is acute and temporary — fails for chronic illness; (b) ignores that patients may rationally question or resist medical authority; (c) ignores how race, class, and gender affect access to the sick role (poor people blamed more for illness); (d) medicalizes normal life processes. Medicalization of deviance: behaviors previously seen as moral failings (alcoholism, ADHD, obesity) redefined as medical conditions requiring treatment.
Cultivation theory (Gerbner and Gross, 1976): long-term, cumulative effects of heavy television exposure — not a single program but the overall television environment. "Mean world syndrome": heavy viewers overestimate their chances of being victimized by crime, perceive the world as more dangerous, and are more fearful than light viewers. First-order cultivation effects: beliefs about the frequency of events (e.g., how often murders occur). Second-order cultivation effects: values and attitudes about social groups and issues. Mainstreaming: heavy TV viewing narrows differences between demographic groups — they converge on TV's "mainstream" worldview. Resonance: when TV content matches viewers' real-world experience, effects are amplified. Contrasting theories: agenda-setting (McCombs and Shaw) — media shapes what people think about (not what they think); framing — media shapes how issues are understood; uses and gratifications (Katz and Lazarsfeld) — audiences actively use media for specific purposes, not passive recipients.
Ritzer (The McDonaldization of Society, 1993) extends Weber's rationalization thesis to consumer society. Four dimensions: (1) Efficiency — finding the optimal means to a given end; the customer does work previously done by employees (self-service); (2) Calculability — emphasis on quantity over quality; size becomes a proxy for value; (3) Predictability — same product and experience regardless of time or location; scripts eliminate discretion; (4) Control — substituting non-human technology for human judgment (conveyor belts, timers, ordering kiosks) — deskilling workers and constraining customers. "Irrationality of rationality": hyper-rationalized systems produce dehumanization, environmental harm, and loss of quality. Examples beyond fast food: universities (MOOCs, standardized curricula), healthcare (managed care protocols), travel (package tours). Criticism of McDonaldization: underestimates consumer agency and local resistance; cultural imperialism critique — but hybridization theory argues local cultures transform global forms (glocalization — Robertson).
Du Bois (The Souls of Black Folk, 1903): "this sense of always looking at one's self through the eyes of others, of measuring one's soul by the tape of a world that looks on in amused contempt and pity." The "veil" — the color line that separates Black Americans from full citizenship and recognition. The "two-ness": American + African = two souls, two thoughts, two unreconciled strivings. The striving to merge these double selves without losing either. Du Bois's insight: racism creates a psychological burden of self-surveillance and self-alienation — you must constantly translate yourself for a dominant culture that dehumanizes you. Historical context: written in response to Booker T. Washington's accommodationism; Du Bois argued for full political and civil rights, not just economic self-improvement. Influence: foundational for African American studies, critical race theory, intersectionality, and postcolonial theory.
Mills (The Sociological Imagination, 1959): "the most fruitful distinction with which the sociological imagination works is between 'the personal troubles of milieu' and 'the public issues of social structure.'" Personal troubles: private matters within an individual's character and immediate social relations. Public issues: matters that transcend local environments and involve the structure of society. Classic example: one unemployed person = personal trouble (laziness, skill deficiency); widespread unemployment = public issue (structural economic failure). The sociological imagination requires understanding three things: (1) the structure of society as a whole and its components; (2) the position of the society in human history; (3) the varieties of human nature — what kinds of people prevail in this society. Mills also critiqued "abstracted empiricism" (mindless data collection) and "grand theory" (incomprehensible abstraction) in sociology of his era.
Simmel (Soziologie, 1908, "Exkurs über den Fremden"): the stranger is not the wanderer who comes today and leaves tomorrow, but "the person who comes today and stays." The stranger's position — spatial proximity combined with social/cultural distance — creates a unique form of interaction: people often confide in strangers more freely (the stranger has no stake in the local social world). The stranger brings objectivity: not bound by local conventions, piety, or special interests. Historical type: the Jewish merchant in medieval Europe — present in but not of the community. Simmel also analyzed the metropolis: urban life creates a "blasé attitude" — a psychological defense against the overstimulation of city life. Both concepts show Simmel's interest in the social forms generated by the meeting of proximity and distance, inclusion and exclusion.
Tocqueville's central anxieties about democracy: (1) Tyranny of the majority — democratic majorities can be as tyrannical as kings; social pressure toward conformity can suppress minority opinion and individual dissent. (2) Individualism — democratic equality fosters withdrawal into private life; people care less about public affairs. (3) Soft despotism (or "administrative despotism"): citizens allow a paternalistic government to care for them in exchange for surrendering political participation and initiative — not brutal tyranny but a "network of small complicated rules" that "covers the surface of society with a network of small complicated rules" and reduces citizens to "timid and industrious animals." Tocqueville's corrective: voluntary associations, local democracy, and civic participation maintain liberty against both majority tyranny and governmental paternalism. His observations remain influential in political sociology, communitarian theory, and debates about civil society.
Esping-Andersen (The Three Worlds of Welfare Capitalism, 1990): decommodification = the degree to which a person can maintain a livelihood without relying on the market (i.e., social rights independent of employment). Three regimes: (1) Liberal (USA, Canada, Australia): residual welfare, means-tested benefits, market-based solutions, modest decommodification, reinforces market inequalities; (2) Conservative/Corporatist (Germany, France, Italy): social insurance tied to occupational status (breadwinner model), high male-worker benefits, family-centered, preserves status differentials, medium decommodification; (3) Social-Democratic (Sweden, Norway, Denmark): universal benefits for all citizens regardless of employment, high quality public services, strong redistribution, high decommodification, low stratification. Criticism: originally ignored gender (Orloff); ignored Southern European and East Asian welfare states. Later scholars added "familialism" as a fourth type.
Conrad and Schneider (Deviance and Medicalization, 1980): medicalization expands the jurisdiction of medicine by redefining deviance, difference, or distress as disease. Examples: alcoholism (from moral failing → disease), ADHD (from bad behavior → neurological disorder), homosexuality (was DSM diagnosis until 1973), childbirth (from normal life event → medical procedure), obesity (from personal choice → medical condition), aging (from normal life stage → series of medical conditions to treat). Medicalization can be beneficial (reduces stigma, provides treatment access) or harmful (pathologizes normal variation, creates pharmaceutical market incentives, increases physician control over life decisions). Pharmaceuticalization: increasingly, medicalization is driven not by physicians but by the pharmaceutical industry — direct-to-consumer advertising, disease-mongering (expanding disease categories). Demedicalization also occurs: homosexuality, masturbation, hyperactivity in girls.
Uses and gratifications theory (Katz, Blumler, and Gurevitch, 1974): (1) audiences are active and goal-directed; (2) media use is functionally motivated; (3) media compete with other sources of need satisfaction. Five categories of gratifications (McQuail): (a) information/surveillance — understanding the world; (b) personal identity — finding values reinforcement and models for behavior; (c) integration and social interaction — connecting with others, conversation fodder; (d) entertainment — escape, emotional release; (e) cognitive/affective stimulation. Contrast with "hypodermic needle" (magic bullet) model: media injects messages directly into passive audiences. U&G shifted media research from "what do media do to people?" to "what do people do with media?" Applied to social media: people use Instagram for identity presentation (Goffman's self-presentation), Facebook for social maintenance, Twitter/X for information and opinion expression.
McCombs and Shaw (1972, Chapel Hill study during 1968 presidential campaign): found strong correlation between the issues emphasized in media coverage and the issues voters considered most important — the "agenda" transferred from media to public. First-level agenda-setting: object salience (which issues are prominent). Second-level agenda-setting (attribute agenda-setting): which attributes or aspects of an issue receive emphasis shapes how people think about the issue (framing). Third-level agenda-setting: network agenda-setting — which associations among objects and attributes are salient. Framing theory (Goffman, Entman): how an issue is framed (e.g., immigration as "economic burden" vs. "cultural enrichment") shapes interpretation and policy preferences. Together, agenda-setting, framing, and priming (activating certain considerations when evaluating politicians) form the dominant paradigm of media effects in political communication research.
Social determinants of health (WHO framework): health outcomes are shaped by conditions in which people are born, grow, live, work, and age — including income, education, neighborhood, employment, and social support. Key patterns: (1) SES gradient — health improves at every step up the socioeconomic ladder (Marmot's Whitehall studies — even high-status British civil servants had worse health than the highest-status group); (2) racial health disparities — Black Americans have higher rates of hypertension, diabetes, maternal mortality, infant mortality, and lower life expectancy than white Americans, even at similar income levels; (3) weathering hypothesis (Geronimus): cumulative stress from living under racism ages the body prematurely — explains why Black women's birth outcomes worsen with age rather than improving. Mechanisms: chronic stress (allostatic load), residential segregation → environmental exposures, healthcare discrimination, differential access to quality care. Race as a social (not biological) variable that affects health through structural mechanisms.
Cultural imperialism (Schiller, Tomlinson): the spread of global capitalism involves the export of culture — Hollywood films, American fast food, pop music, advertising, and consumer values — that displaces local cultural production and subordinates local values to Western (capitalist, individualist) norms. The result: cultural homogenization ("Americanization" or "Westernization") that reinforces economic dependency. Counter-argument — hybridization (glocalization, Robertson): global cultural flows are not simply imposed top-down; local cultures actively appropriate, transform, and creolize global cultural inputs to produce new hybrid forms. Examples: Bollywood + Hollywood = Bollywood films that incorporate but transform Western genres; hip-hop becomes a vehicle for local political expression worldwide; McDonald's menus adapted to local tastes. Neither pure imperialism nor pure hybridity — the reality involves unequal power relations alongside creative local appropriation.
In Goffman's dramaturgical framework, impression management strategies include: (a) controlling props, costumes, setting, and manner to frame desired identity; (b) audience segregation — preventing different audiences from seeing incompatible performances (a doctor with patients vs. colleagues; a person with parents vs. friends); (c) mystification — performers maintain distance and limit information access to enhance their aura of authority (surgeons don't explain every step; magicians hide their methods); (d) team performance — actors cooperate to sustain a shared definition of the situation. "Mortification of the self" appears in Goffman's "Asylums" (1961) as what total institutions do to inmates — stripping personal identity through deindividuation practices. It is not a performer's strategic choice but an institutional imposition. Other concepts: face-work (Goffman, "Interaction Ritual") — managing one's public image and avoiding loss of "face" (public self-image).
Burt (Structural Holes, 1992; Brokerage and Closure, 2004): a structural hole exists when two contacts of a network actor are not connected to each other — the actor bridges an otherwise disconnected gap. The "broker" at a structural hole has three advantages: (1) information benefits — access to diverse, non-redundant information from multiple clusters; (2) timing — information arrives earlier and can be exploited before it diffuses; (3) control — ability to filter, translate, and time information flows between disconnected parties. Burt's "social capital" is therefore individual and competitive (vs. Putnam's collective social capital). Burt vs. Coleman: Coleman emphasized closure (dense, overlapping networks) as the source of trust and norms; Burt emphasized holes as the source of brokerage advantage. Both are valuable: closure generates trust and coordination within clusters; brokerage generates information and innovation across clusters.
Stouffer et al. (The American Soldier, 1949): surprising finding — soldiers in units with high promotion rates were MORE dissatisfied with promotion than soldiers in low-promotion units. Explanation: those in high-promotion units compared themselves to more promoted peers, feeling relatively deprived despite objectively better conditions. Merton formalized the concept: reference group theory — people evaluate their own situation relative to a comparison group, not in absolute terms. Applications: (a) inequality and happiness — beyond a threshold, relative income predicts well-being better than absolute income (Easterlin paradox); (b) social movements — Gurr's "relative deprivation theory of civil violence" — political violence arises from the gap between expected and actual living conditions; (c) social comparison in media — exposure to idealized images increases body dissatisfaction regardless of actual weight. Critical note: relative deprivation explains attitudes but is insufficient to explain when movements actually form (resource mobilization is also needed).
Durkheim (The Division of Labor in Society, 1893): Mechanical solidarity (traditional/premodern societies): cohesion based on sameness — shared values, beliefs, customs, and religious worldview (the "collective conscience"); strong, all-encompassing; deviance is an offense against the entire community → repressive law (punishment, retribution). Organic solidarity (modern industrial societies): cohesion based on difference — interdependence of specialized roles; the division of labor creates mutual dependency even among people with different values; weaker collective conscience; deviance is a breach of contract or social norms → restitutive law (restoration, compensation, mediation). The "anomie" risk: as societies transition, if organic solidarity develops faster than new moral norms, social cohesion breaks down. Both parts of option D correctly describe Durkheim's framework: (B) the types of social cohesion and their societal context; (C) the corresponding types of legal sanction.
Status inconsistency (Lenski, 1954): in multidimensional stratification (class, status, power — Weber), individuals may occupy different ranks across dimensions. Examples: a highly educated Black professional in a racist society (high education/prestige, disadvantaged by race); a wealthy but poorly educated person (high income, low prestige); a Catholic in a historically Protestant-dominant country (religious minority despite economic success). Consequences: (a) psychological stress — uncertain which status to claim in interaction, and which others will recognize; (b) political radicalism — consistent findings that status inconsistents support redistributive policies and social change; rationale: they have experienced the arbitrariness of status assignments and are motivated to reform the system. Status inconsistency helps explain why some high-income individuals support progressive taxation and why newly arrived ethnic minorities sometimes become politically active. Also relevant to intersectionality: privilege in one dimension does not negate disadvantage in another.
Allport (The Nature of Prejudice, 1954): mere contact is insufficient — and can even increase prejudice (if competitive or unequal). Four optimal conditions: (1) equal status in the situation; (2) cooperative (not competitive) interdependence — working toward common goals; (3) common goals that require collaboration; (4) institutional support — sanctioned by authorities (school policy, laws, community norms). Mechanisms: personalization breaks outgroup homogeneity ("they're all alike") → extended contact hypothesis (Wright): even knowing an ingroup member who has an outgroup friend can reduce prejudice; (b) anxiety reduction; (c) perspective-taking and empathy. Meta-analyses (Pettigrew and Tropp, 2006): 94% of 515 studies found contact reduces prejudice; effect holds even when Allport's conditions are not fully met. Applied: school desegregation research — integration sometimes increased prejudice when conditions were competitive and unequal (e.g., tracking resegregated schools internally).
Merton coined "Matthew effect" (1968, from Matthew 25:29: "For unto every one that hath shall be given...but from him that hath not shall be taken away"). In science: when two scientists of different status make the same discovery, the eminent scientist receives more credit (citations, prizes, positions) than the obscure scientist. Accumulated advantage: early recognition → more resources (grants, equipment, students) → more productivity → more recognition. The same effect extends beyond science: (a) education — students who receive enriched instruction early gain compounding advantages; (b) labor markets — early career success predicts later career success disproportionately to actual productivity differences; (c) wealth — compound interest exemplifies material Matthew effects. Related: cumulative disadvantage (O'Rand): disadvantage accumulates over the life course — a bad early break (poor school, health crisis) compounds into later poverty. The Matthew effect is central to understanding why initial inequality tends to widen over time.
Weber's multidimensional stratification (Economy and Society): (1) Class: economic dimension — market position, life chances, control over productive resources; classes share objective economic interests but may not form social communities (contrast Marx's emphasis on class as primary determinant of all inequality); (2) Status groups (Stände): social honor, prestige, lifestyle, consumption — defined by shared way of life, not just economic position; status can be independent of class (a broke aristocrat, a nouveau riche businessman without social acceptance); (3) Party: organized groups oriented toward acquiring power — political parties, factions, pressure groups; can be based on class or status interests but are analytically distinct from both. Key insight: class position does not automatically translate into status or political power — they are correlated but independent. This allows Weber to explain phenomena Marx's class analysis cannot: why high-income people may have low prestige, why status groups maintain exclusion even from economically successful outsiders.
Michels (Political Parties, 1911): studied German Social Democratic Party (explicitly egalitarian and democratic). Observed: as the party grew, it required professional leadership, bureaucratic administration, and technical expertise — which concentrated decision-making in a small leadership group. Leaders developed interests in organizational survival and their own positions, becoming conservative even in a "radical" party. Three mechanisms: (1) organizational necessity — complex tasks require specialization and delegation; (2) psychological factors — masses prefer to be led; leaders develop specialized skills and communication advantages; (3) political factors — leaders control organizational resources (finances, media, travel funds) and use them to maintain power. Pessimistic conclusion: socialist democracy is a contradiction in terms — even truly egalitarian movements must compromise their ideals to function. Criticism: overstated — the degree of oligarchy varies; some organizations remain more democratic than others through structural design (term limits, mandatory rotation, participatory democracy).
Bourdieu (Outline of a Theory of Practice, 1972; The Logic of Practice, 1990): habitus = embodied social structure; the internalization of objective class conditions into subjective dispositions. Key properties: (a) durable — formed in early childhood through prolonged exposure to a class position; (b) transposable — dispositions developed in one field tend to transfer to others; (c) generative — produces an infinite range of practices adapted to situations without explicit rule-following (like a jazz musician improvising). Habitus operates below the level of conscious reflection — it feels "natural" or "common sense." Examples: working-class habitus may generate deference to authority, preference for practical knowledge, discomfort in elite cultural settings; upper-class habitus generates ease in formal settings, assumption of entitlement. Habitus + field + capital: Bourdieu's formula for understanding social action. Field = a structured social space with its own rules and stakes; capital (economic, cultural, social, symbolic) = resources deployed to succeed in fields.
Lemert's distinction (Social Pathology, 1951): Primary deviance = initial norm violations that occur for various reasons and may be excused, ignored, or rationalized by the actor without altering their self-concept. Secondary deviance = when primary deviance leads to public labeling → the labeled person internalizes the "deviant" master status → reorganizes life around the deviant identity → deviant subculture → career deviance. Example: a teenager caught shoplifting (primary deviance) → labeled "delinquent" → treated as a delinquent by school, family, peers → excluded from conventional opportunities → increased association with delinquent peers → more serious deviance (secondary). Becker (Outsiders, 1963): "deviance is not a quality of the act but of the application of rules and sanctions by others." Moral entrepreneurs: those who create and enforce moral rules. Deviant career: stages of progressive involvement in deviant identity. Self-fulfilling prophecy: labeling produces the very behavior it predicted.
Crenshaw (1989, "Demarginalizing the Intersection of Race and Sex"): originating in legal context — antidiscrimination law failed Black women because courts required them to either claim race discrimination (comparing to Black men) OR sex discrimination (comparing to white women) — neither captured their specific experience. Example: General Motors hired Black employees (in factory jobs) and female employees (in office jobs) but not Black women in either context — a discrimination that affected only Black women. Intersectionality holds that systems of oppression (racism, sexism, classism, heterosexism) interact at the micro level of individual experience and at the macro level of institutional structures — producing qualitatively new, not merely additive, forms of disadvantage. An intersectional approach: (1) centers the experiences of the most marginalized; (2) rejects single-axis analysis; (3) examines how multiple systems simultaneously shape identity and opportunity. Now applied across many social dimensions: race, gender, class, sexuality, disability, immigration status, religion.
Hochschild (The Second Shift, 1989) documented that employed women perform a "second shift" of domestic labor and childcare beyond their paid work — equivalent to an extra month of work per year compared to their male partners. The concept of a "third shift" extends this: the emotional work of managing children's psychological well-being, scheduling, relationship difficulties, and the invisible cognitive and emotional coordination of family life. Hochschild (The Managed Heart, 1983) also introduced emotional labor: the management of feeling to create publicly acceptable facial and bodily displays — disproportionately expected of women in service work (flight attendants, nurses, customer service). Gender gap in domestic labor persists even in "egalitarian" couples — husbands often "help" rather than share equally; mental load (cognitive labor of planning, remembering, coordinating) falls disproportionately on women. COVID-19 research showed pandemic increased the gender gap in domestic labor as childcare responsibilities expanded.
Merton (Social Theory and Social Structure, 1949): refined Parsonian functionalism by introducing more precise concepts. Manifest functions: intended and recognized positive consequences of a social pattern. Latent functions: unintended and unrecognized consequences — may be positive (latent functions) or negative (latent dysfunctions). Classic examples: (a) Rain dance — manifest function: produce rain; latent function: strengthen group solidarity and reinforce cultural identity. (b) Education — manifest functions: transmit knowledge, credential workers; latent functions: childcare, mate selection, hidden curriculum (teaching conformity and hierarchy). (c) Poverty (Gans, 1972): manifestly recognized as harmful; latent functions — provides cheap labor, creates jobs for social workers and police, provides cultural scapegoats. Merton also introduced "functional alternatives" — multiple structures can perform the same function. This is a refinement over simple functionalism that assumed only one structure could serve each function.
Push-pull theory (Ravenstein's laws of migration, 1885; Lee, 1966): migration decisions result from the interplay of conditions at origin and destination, plus intervening obstacles (distance, immigration laws, transportation costs). Push factors: economic (unemployment, poverty, land scarcity), political (persecution, war, ethnic violence), social (discrimination, caste restrictions), environmental (natural disasters, climate change). Pull factors: economic (higher wages, employment opportunities, land), political (freedom, stability, democratic rights), social (family reunification, established ethnic communities), environmental (better climate, safety). Intervening obstacles: immigration enforcement, distance, cultural/language barriers, travel costs. Network theory of migration: existing migrant communities in destination areas reduce the cost and risk of migration for subsequent migrants — explaining "chain migration" and the persistence of migration flows even when initial push-pull conditions change. Wallerstein's world systems theory: migration flows from periphery to core nations reflect the structural inequalities of the capitalist world economy.
Durkheim's typology (Suicide, 1897) organized around two dimensions: integration (strength of bonds to social group) and regulation (strength of normative constraints on aspirations). Egoistic suicide: low integration — individual lacks social bonds, lives for themselves → depression, meaninglessness. Altruistic suicide: high integration — individual subordinates self to group to the point of self-sacrifice; examples: kamikaze pilots, ritual suicide of widows (sati), soldiers who fall on grenades. Anomic suicide: low regulation — normative framework collapses (during economic crises, divorce); aspirations are unlimited and unsatisfiable → frustration, despair. Fatalistic suicide: high regulation — individual's future is completely blocked by social oppression (Durkheim's least developed type); examples: enslaved people, prisoners. Durkheim's key argument: suicide rates are social facts — they vary systematically with social integration and regulation, demonstrating that ostensibly private, individual acts have social causes that sociology can explain.
Sutherland (1939 presidential address to American Sociological Society): challenged the dominant view that crime is associated with poverty, mental illness, and social disorganization in lower-class urban areas. Demonstrated that wealthy and powerful individuals routinely commit costly crimes: corporate fraud, embezzlement, bribery, securities violations, antitrust violations. The crimes cause enormous economic harm — far exceeding street crime costs. Yet prosecution, conviction, and incarceration rates are far lower for white-collar offenders: (a) regulatory rather than criminal proceedings; (b) fines rather than imprisonment; (c) powerful attorneys and social connections; (d) "respectable" defendants get judicial sympathy. This demonstrates that the criminal justice system is not class-neutral. Sutherland's differential association theory: all crime — including white-collar — is learned through association with definitions favorable to law violation. Extensions: corporate crime (Clinard), organizational crime, state-corporate crime, cybercrime — expanding the white-collar concept to organizational and structural levels.
W.I. and Dorothy Thomas (The Child in America, 1928): subjective definitions of situations have objective consequences — even if the definition is objectively inaccurate. Classic applications: (a) bank run — if people believe a bank is insolvent (even if it isn't) and withdraw funds, the bank becomes insolvent → self-fulfilling prophecy (Merton extended this concept); (b) racial prejudice — if people define an outgroup as inferior and threatening, they treat them accordingly, producing outcomes that seem to confirm the definition; (c) student ability — teachers who define students as low-ability treat them differently, reducing actual achievement (Pygmalion effect/Rosenthal). The Thomas Theorem is foundational for: symbolic interactionism, social constructionism (Berger and Luckmann — The Social Construction of Reality, 1966), ethnomethodology (Garfinkel — how do people construct and sustain shared definitions of situations through everyday interaction?), and labeling theory. Contrast with objective structural theories: behavior is determined by objective conditions, not actors' perceptions of them.
Standpoint theory (Hartsock, Smith, Harding, Collins): all knowledge is situated — produced from a particular social location (race, class, gender, sexuality). The "view from nowhere" of traditional science is actually the view from dominant group positions (white, male, Western, bourgeois) mistaken for universal objectivity. Marginalized standpoints offer a "strong objectivity" (Harding): because marginalized people must understand both their own world and the dominant world to navigate it, they often see systemic patterns invisible to the privileged. Dorothy Smith (The Everyday World as Problematic): sociology has been done from men's standpoint — sociology for women starts from women's actual daily experience. Collins (Black Feminist Thought): Black women's outsider-within position (present in but not fully of dominant institutions) enables unique insights into both dominant and subordinate social worlds. Not relativism: standpoint theorists argue some standpoints provide better starting points for inquiry — not that all standpoints are equally valid. Applied: research "for" vs. "about" marginalized groups; community-based participatory research.
Putnam (Bowling Alone, 2000): Bonding social capital = strong intra-group ties among similar people (same ethnicity, religion, class, neighborhood) → generates solidarity, emotional support, material assistance within the group, strong norms of reciprocity. But can be exclusionary — high bonding capital groups may enforce conformity and create hostility toward outgroups (ethnic gangs, religious sects). Bridging social capital = weak ties across different social groups → provides access to diverse information, different resources, and promotes inclusive social integration. "Bonding capital is good for getting by; bridging capital is good for getting ahead." Associations can have both: a bowling league might bond Italian Americans (bonding) while the civic context creates cross-class friendships (bridging). Policy implications: programs to increase bridging capital (inter-ethnic contact, cross-class public spaces) may be more important for social cohesion than reinforcing within-group ties. Putnam's Bowling Alone thesis: American social capital (both types) declined in the late 20th century due to suburbanization, TV, generational change, and time pressure.
Bowles and Gintis (Schooling in Capitalist America, 1976): the "correspondence principle" — the social relations of education (teacher-student hierarchy, grades as extrinsic motivation, lack of student control, compliance rewarded) mirror the social relations of capitalist production (boss-worker hierarchy, wages as extrinsic motivation, worker alienation from product). Schools don't primarily teach cognitive skills — they socialize students to accept authority, work for external rewards, and fit into their pre-assigned position in the capitalist hierarchy. Class reproduction: working-class schools emphasize rule-following and obedience; elite schools emphasize creativity and leadership — reproducing the class hierarchy across generations. Criticism: overly deterministic — ignores student resistance (Willis, Learning to Labour: working-class "lads" resist schooling but in ways that paradoxically reproduce their class position); ignores contradictions within schools; fails to account for upward mobility. Still influential as a structural critique of meritocracy and a framework for understanding school-work articulation.
The sex/gender distinction was formalized by feminist sociologists and scholars (Oakley, Sex, Gender and Society, 1972) to challenge biological determinism. Sex: chromosomes (XX, XY, and variations — intersex), hormones, gonads, reproductive anatomy — biological. Gender: the meanings, roles, expectations, and identities society attaches to being masculine, feminine, or gender-diverse. Gender varies: cross-cultural evidence (Margaret Mead, Sex and Temperament, 1935 — different societies assign different traits to men and women) and historical evidence (shifting definitions of masculinity and femininity over time) demonstrate gender is socially constructed, not biologically fixed. Doing gender (West and Zimmermann, 1987): gender is not a property of individuals but an ongoing social performance and interactional accomplishment — people "do" gender in every interaction by enacting culturally expected behaviors. The sex/gender binary itself is now questioned: intersex bodies show that biological sex is also a spectrum; transgender and non-binary identities demonstrate gender's variability beyond the binary.
Demographic transition model (Thompson, 1929; Notestein, 1945): Stage 1 — pre-industrial: high CBR (crude birth rate), high CDR (crude death rate) → slow natural increase; Stage 2 — early industrial: CDR falls (public health, sanitation, food supply) while CBR remains high → rapid population growth (the "population explosion"); Stage 3 — late industrial: CBR falls (urbanization, women's education, contraception, child labor laws reduce value of children) → growth slows; Stage 4 — post-industrial: low CBR, low CDR → slow growth or stability; Stage 5 (disputed) — sub-replacement fertility → population decline (as in Japan, South Korea, Italy, Germany). The model describes the historical experience of Western Europe and North America; debates: whether it applies universally to all developing nations, whether sub-Saharan Africa will follow the same trajectory, and whether the "second demographic transition" (delayed marriage, cohabitation, low fertility) in wealthy nations represents a new stage. Policy implications: population pyramids, dependency ratios, and pension system sustainability.
Durkheim (The Rules of Sociological Method, 1895): deviance is a "normal" feature of all societies — if no crime existed, reactions would focus on ever-more-minor infractions. Functions of deviance (elaborated by Erikson, Wayward Puritans, 1966): (1) Boundary clarification — crimes trigger collective outrage that reaffirms the boundaries of acceptable behavior and the shared values of the community (Durkheim: "crime brings together upright consciences and concentrates them"); (2) Social cohesion — shared condemnation of the deviant reinforces in-group solidarity; (3) Social change — yesterday's deviant may be tomorrow's hero; civil rights protesters, suffragists, and religious reformers were deviants in their time; deviance can challenge and ultimately change unjust norms. Note: these are functionalist arguments — they explain deviance at the macro level as serving social purposes, without excusing specific harmful acts or denying the suffering of victims. Contrast with conflict theories of deviance: who has the power to define what is deviant?
Hyman coined "reference group" (1942) to describe the groups people use to evaluate their own attitudes, beliefs, and behaviors. Merton and Rossi elaborated the concept's sociological significance. Types: (a) Membership reference group: one's own group used as comparison (comparing salary to coworkers); (b) Non-membership/aspirational reference group: a group one aspires to join, whose standards are adopted in anticipation (working-class student adopting middle-class norms in college); (c) Negative reference group: a group one explicitly does not want to resemble (influencing behavior through avoidance). Functions: self-evaluation (am I doing well compared to my reference group?); norm acquisition (what are the standards of behavior in the group I aspire to?); frame of reference for social comparison. Applications: relative deprivation (comparing to a reference group that is doing better → resentment); anticipatory socialization (adopting the norms of a group before joining); consumer behavior (aspiring to consume like a desired reference group); political attitude formation (comparing one's party's performance to the opposition).
Wallerstein (The Modern World-System, 1974): Core nations (USA, Western Europe, Japan): high-skill, capital-intensive production; high wages; export manufactured goods and services; extract surplus from the periphery through trade. Periphery nations: low-skill, labor-intensive production; low wages; export raw materials and agricultural goods; subject to unequal exchange. Semi-periphery (Brazil, Mexico, South Korea, India, China in various periods): intermediate characteristics — some manufacturing but also raw material export; may exploit periphery while being exploited by core; political role as buffer preventing polarized core-periphery conflict. Semi-periphery nations can move up (South Korea, Taiwan industrialized into near-core status) or down (some formerly important nations declined). The world-system is a single capitalist economy with multiple political units (nation-states) — competition among states is part of the system's structure. Critique of modernization theory: development and underdevelopment are not independent national processes but are produced by the same world-system — some nations become rich by making others poor (dependency theory — Frank).
Hidden curriculum (Philip Jackson, Life in Classrooms, 1968; elaborated by Bowles and Gintis, Illich, Apple): schools transmit far more than the formal academic curriculum. The hidden curriculum includes: (a) learning to wait, follow instructions, and defer to authority without question; (b) accepting evaluation, grading, and ranking by external authorities; (c) learning that one's worth is measured by performance on standardized tasks; (d) internalizing punctuality, orderly behavior, and productivity as virtues; (e) class-differentiated hidden curricula — working-class schools emphasize following rules, middle-class schools emphasize finding the right answer, elite schools emphasize developing your own perspective (Anyon, 1980, study of social class and the hidden curriculum). The hidden curriculum is "hidden" because it is not stated in educational objectives — it operates through the structure, environment, and implicit messages of schooling. Contested: some argue the hidden curriculum reproduces capitalism and class hierarchy (Bowles/Gintis); others argue it transmits civic virtues and democratic participation skills.
Davis and Moore (1945, "Some Principles of Stratification"): the most widely cited and critiqued functionalist argument for inequality. Logic: (1) some positions are more functionally important than others for societal survival; (2) some positions require rare talents or long training; (3) society must offer greater rewards (income, prestige, power) to attract and motivate qualified people to fill these positions; (4) therefore, social stratification is universal and functionally necessary. Classic critique (Tumin, 1953): (a) how do we objectively determine which positions are most "functionally important"? (b) stratification itself blocks access to training for talented people in lower classes — restricts the talent pool; (c) non-economic motivations (altruism, intrinsic satisfaction) are ignored; (d) many high-prestige positions (surgeons) are not demonstrably more important than low-prestige ones (sanitation workers); (e) functional importance ≠ current reward level (childcare workers vs. hedge fund managers). Conflict theory response (Tumin, Collins): stratification reflects power and exploitation, not functional necessity — those at the top use their power to maintain and justify inequality.
