Sociology

Founding Theorists

• Herbert Spencer (1820–1903) — coined “survival of the fittest” and applied evolutionary thinking to society (social Darwinism): societies evolve from simple, militaristic forms to complex, industrial ones; argued against state intervention as interfering with natural selection; influenced by (but distinct from) Darwin; criticized by Durkheim and later sociologists for naturalistic fallacy.
• Jane Addams (1860–1935) — co-founder of Hull House in Chicago (1889), one of the first settlement houses in the United States; pioneered applied sociology and social work; documented poverty and immigrant life through empirical methods; awarded the Nobel Peace Prize in 1931; also a key figure in the women’s suffrage and pacifist movements; her empirical reformism was often marginalized by the male-dominated Chicago School despite her foundational contributions.
• Auguste Comte (1798–1857) — French philosopher credited with coining the term sociologie; advocated positivism: applying scientific method to social phenomena; proposed the law of three stages (theological, metaphysical, positive/scientific).
• Harriet Martineau (1802–1876) — translated and abridged Comte; first woman sociologist; conducted empirical studies of British and American society; argued sociology must address gender and race.
• Karl Marx (1818–1883) — grounded sociology in historical materialism: the material/economic base (forces and relations of production) determines the ideological superstructure; coined bourgeoisie (capitalist class) and proletariat (working class); alienation (Entfremdung) describes workers estranged from their labor, products, and humanity under capitalism; false consciousness prevents workers from seeing their exploitation; class conflict drives history; commodity fetishism: the social relations between people are masked and appear as relations between things (the commodity and its price), mystifying the labor embedded in goods. Key works: Communist Manifesto (with Engels, 1848), Capital (1867).
• Émile Durkheim (1858–1917) — established sociology as a discipline separate from philosophy and psychology; introduced social facts: external, coercive forces that constrain individual behavior (e.g., laws, norms); collective conscience: shared beliefs binding society; anomie: a breakdown of social norms, especially during rapid change; Suicide (1897) demonstrated social (not merely psychological) causes of self-destruction — four types: egoistic (low integration), altruistic (excessive integration), anomic (low regulation), fatalistic (excessive regulation); The Division of Labor in Society (1893): mechanical solidarity (traditional, homogeneous) versus organic solidarity (modern, differentiated interdependence); The Elementary Forms of the Religious Life (1912): religion’s social function is to bind communities through shared rituals; distinguished the sacred (set apart, forbidden) from the profane (ordinary); the totem as the earliest religious symbol encoding collective identity.
• Max Weber (1864–1920) — emphasized verstehen (interpretive understanding) of subjective social meaning; ideal type: an analytical construct exaggerating a phenomenon’s features for comparison; The Protestant Ethic and the Spirit of Capitalism (1905): argues Calvinist predestination theology produced the Protestant ethic — anxiety over salvation displaced into disciplined, ascetic, rational labor, accumulating capital rather than spending it; this “spirit of capitalism” underpins modern economic life; rationalization: a historical process by which tradition is replaced by calculation and efficiency; bureaucracy: the ideal-typical form of modern rational-legal authority, characterized by hierarchy, written rules, impersonality, and meritocracy; the iron cage (stahlhartes Gehäuse): rationalized bureaucratic capitalism imprisons individuals in a system of efficient but spiritually empty control; three types of legitimate authority: traditional (custom and precedent), charismatic (personal devotion to a leader), and rational-legal (rules and office); social stratification: class (economic), status (prestige), and party (power) as separate but overlapping dimensions.
• Georg Simmel (1858–1918) — German sociologist focused on micro-level social forms; formal sociology: abstracting the forms of social interaction (conflict, exchange, domination) from their content; dyad vs triad: a two-person group is uniquely fragile; the stranger as a social type who is near yet distant; The Metropolis and Mental Life (1903): the city produces a blasé attitude as a defense against overstimulation.
• W.E.B. Du Bois (1868–1963) — first African American PhD from Harvard; The Souls of Black Folk (1903); coined double consciousness: the sense of looking at oneself through others’ eyes in a racist society; the color line as the central problem of the 20th century; early empirical urban sociology in The Philadelphia Negro (1899); criticized Booker T. Washington’s accommodation strategy.

American and Chicago School Sociology

• Chicago School — the dominant tradition in American sociology from roughly 1915–1940 centered at the University of Chicago; pioneered urban sociology and qualitative field methods; key figures include Robert Park, Ernest Burgess, Louis Wirth, and W.I. Thomas; produced landmark ethnographies and ecological models of city life; Wirth’s urbanism as a way of life (1938) argued cities produce anonymity, secondary relationships, and heterogeneity.
• Robert E. Park (1864–1944) — Chicago School founder; developed human ecology: the city as a natural organism in which competition, invasion, and succession drive spatial organization; the concentric zone model (with Burgess) depicts cities expanding outward in rings; studied race relations and coined the race relations cycle (contact, competition, accommodation, assimilation).
• W.I. Thomas (1863–1947) — Chicago sociologist; The Polish Peasant in Europe and America (1918, with Znaniecki): landmark immigration study using personal documents; formulated the Thomas theorem with Dorothy Thomas: “If men define situations as real, they are real in their consequences.”
• C. Wright Mills (1916–1962) — The Sociological Imagination (1959): ability to see how personal troubles connect to public issues and to situate biography within history; The Power Elite (1956): a small, interlocking network of corporate, military, and political leaders makes key decisions in American democracy, undermining pluralism.

Major Theoretical Paradigms

Structural Functionalism

• Core premise — society is a system of interdependent parts; each institution serves a function maintaining social order and equilibrium.
• Talcott Parsons (1902–1979) — dominant American theorist mid-20th century; AGIL schema: Adaptation, Goal attainment, Integration, Latency (pattern maintenance) — four functional imperatives of any social system; The Social System (1951) described the sick role (illness as a social status with rights and obligations) and pattern variables (five binary choices actors make when orienting to a situation, e.g., universalism vs particularism).
• Robert K. Merton (1910–2003) — distinguished manifest functions (intended, recognized) from latent functions (unintended, unrecognized); concept of dysfunction; coined strain theory (see Deviance section) and the self-fulfilling prophecy; coined role strain and role conflict.
• Criticism — tends toward conservatism; explains stability but not change; assumes consensus where there may be coercion.

Conflict Theory

• Core premise — society is characterized by inequality and conflict over scarce resources; dominant groups maintain power at others’ expense.
• Neo-Marxist extensions — Antonio Gramsci’s hegemony: ruling class maintains power through cultural dominance, not just force. C. Wright Mills’ power elite: a small interconnected group (corporate, military, political) dominates U.S. decision-making.
• Ralf Dahrendorf — broadened conflict theory beyond class to any authority relationship; Class and Class Conflict in Industrial Society (1959).

Symbolic Interactionism

• Core premise — society is constructed through everyday face-to-face interaction and the meanings people attach to symbols; focuses on the micro-level.
• George Herbert Mead (1863–1931) — the self arises through social interaction; the I (spontaneous self) vs the Me (socialized self reflecting others’ expectations); the generalized other: internalized image of how society expects one to act; Mind, Self, and Society (1934, posthumous).
• Charles Horton Cooley (1864–1929) — looking-glass self: self-concept built through imagining how others see us; primary groups: small, intimate, face-to-face groups (family, close friends) that form the basis of personality and social norms.
• Herbert Blumer (1900–1987) — coined the term symbolic interactionism; three premises: people act toward things based on their meanings; meaning arises from social interaction; meanings are interpreted and modified through an interpretive process.
• Erving Goffman (1922–1982) — dramaturgy: social life as a theatrical performance; front stage (public performance) vs back stage (private self); impression management: individuals actively control others’ perceptions; Stigma (1963): stigma as a spoiled identity; total institutions: complete control environments (prisons, asylums) that strip and rebuild identity.

Feminist Theory

• Core premise — gender is a fundamental axis of social organization; sociology has historically privileged male perspectives.
• First-wave — suffrage and legal equality (19th–early 20th century).
• Second-wave — 1960s–1980s; focused on patriarchy, workplace inequality, reproductive rights; Betty Friedan (The Feminine Mystique, 1963) identified the “problem that has no name.”
• Third-wave / intersectionality — Kimberlé Crenshaw coined intersectionality (1989): race, class, gender, sexuality, and other categories interact and cannot be analyzed in isolation.
• Dorothy Smith — standpoint theory: knowledge is situated; the “relations of ruling” are best visible from the margins.
• Judith Butler — gender performativity (Gender Trouble, 1990): gender is not innate but produced through repeated performances; denaturalizes the sex/gender binary.

Other Paradigms

• Postmodernism — rejects grand narratives; emphasizes fragmentation, discourse, and power-knowledge. Michel Foucault: discourse shapes what counts as knowledge; disciplinary power operates through surveillance (the panopticon as metaphor).
• Exchange theory — George Homans and Peter Blau: social interaction as rational exchange of rewards and costs; related to rational-choice sociology.
• Network theory — focuses on patterns of relationships (ties) rather than attributes; Mark Granovetter’s strength of weak ties (1973): weak ties are more valuable for information flow than strong ties.
• World-systems theory (Immanuel Wallerstein) — The Modern World-System (1974): capitalism operates as a single global system divided into core (wealthy, industrialized nations that extract surplus), semi-periphery (intermediate), and periphery (poor nations supplying raw materials and cheap labor); challenges modernization theory’s assumption that all nations follow the same development path.
• Structuration theory (Anthony Giddens) — The Constitution of Society (1984): the duality of structure — social structures both enable and constrain action, while human agency continuously reproduces and transforms those structures; rejects the agency/structure dichotomy; also coined the concept of reflexive modernity.
• Risk society (Ulrich Beck) — Risk Society (1986): modern industrial society generates manufactured risks (nuclear, chemical, ecological) that transcend class, national borders, and traditional safety nets; “reflexive modernization” is a self-confrontation with industrial society’s side effects.
• Liquid modernity (Zygmunt Bauman) — Liquid Modernity (2000): contemporary life is characterized by fluidity, impermanence, and the dissolution of stable social bonds; contrast with “solid” modernity’s fixed institutions and long-term projects; extends to liquid love, liquid surveillance.
• Public sphere (Jürgen Habermas) — The Structural Transformation of the Public Sphere (1962): a bourgeois communicative space, separate from state and market, in which private citizens reason together about public affairs; its colonization by mass media and commercial interests undermines democratic deliberation; communicative action: oriented to mutual understanding rather than strategic success.
• McDonaldization (George Ritzer) — The McDonaldization of Society (1993): Weber’s rationalization thesis updated; four principles — efficiency, calculability, predictability, control through non-human technology — now permeate healthcare, education, and leisure; produces irrationality of rationality (dehumanization, environmental harm).
• Marshall McLuhan (1911–1980) — Canadian media theorist; “the medium is the message” (Understanding Media, 1964): the form of a medium shapes cognition and society independently of the content it carries (e.g., print fosters linear, individualist thought; television fosters participation and immediacy); coined the global village: electronic media collapse space and time, binding the world into a single interconnected community resembling an oral village; distinguished hot media (high-definition, low participation: radio, film) from cool media (low-definition, high participation: telephone, television).
• Strength of weak ties (Mark Granovetter) — 1973 paper in American Journal of Sociology: information, job leads, and novel resources flow through weak ties (acquaintances) rather than strong ties (close friends) because weak ties bridge different social clusters; foundational for network sociology and job-search research.

Core Concepts

Culture and Socialization

• Gemeinschaft vs Gesellschaft (Ferdinand Tönnies) — Community and Society (1887): Gemeinschaft (community): intimate, traditional, bound by kinship and custom; Gesellschaft (society/association): impersonal, contractual, rational-interest-based ties characteristic of modern urban life; one of the first formal typologies of social organization.
• Culture — the shared beliefs, values, norms, and material objects of a group; material culture (physical objects) vs non-material culture (ideas, values, norms).
• Norms — shared rules for behavior; folkways (minor norms, e.g., table manners) vs mores (core moral norms, e.g., prohibitions on theft) — distinction from William Graham Sumner.
• Values — broad cultural standards of what is desirable; norms operationalize values.
• Socialization — the lifelong process by which individuals learn and internalize culture; primary socialization (family, early childhood) vs secondary socialization (schools, peers, media).
• Agents of socialization — family, peer groups, schools, mass media, religion, workplace.
• Resocialization — replacing old norms with new ones; occurs in total institutions (Goffman).
• Subculture — a group with distinct norms and values within the larger culture. Counterculture — a subculture that actively opposes mainstream values (e.g., 1960s counterculture).
• Cultural relativism — judging cultures by their own standards, not outsiders’. Ethnocentrism — judging other cultures by one’s own cultural standards.
• Sapir-Whorf hypothesis — language shapes thought and perception (strong version: linguistic determinism; weak version: linguistic relativity).

Social Structure

• Hawthorne effect — workers in the Hawthorne Works (Western Electric) studies of the 1920s–30s increased productivity when observed, regardless of the specific change made; interpreted as showing that attention and awareness of being studied alter behavior; foundational for critiques of observational research; later meta-analyses question the original interpretation.
• Panopticon — Jeremy Bentham’s 1791 prison design in which inmates cannot tell when they are being watched; Michel Foucault (Discipline and Punish, 1975) uses it as a metaphor for modern disciplinary power: internalized surveillance produces self-regulating subjects.
• Status — a socially defined position; ascribed status (assigned at birth — race, sex) vs achieved status (earned through effort — occupation, education); master status: the status that overrides all others in social interactions.
• Role — the expected behavior associated with a status; role conflict: incompatible demands from two roles; role strain: incompatible demands within a single role; role exit: the process of leaving a role.
• Social groups — in-group (group one identifies with) vs out-group (group one sees as other); reference group: group used as a standard for self-evaluation.
• Social networks — the web of relationships linking individuals; social capital (Bourdieu, Coleman): resources embedded in social ties; Robert Putnam’s Bowling Alone (2000) argued that civic participation and social capital in the United States declined sharply in the late 20th century, measured by falling rates of club membership, voting, and informal socializing.
• Bureaucracy — Weber’s ideal type: hierarchy, written rules, impersonality, meritocracy, specialization; McDonaldization (George Ritzer): extension of fast-food rationalization principles (efficiency, calculability, predictability, control) to all sectors of society.
• Digital divide — the gap in access to and use of information and communication technologies (especially the internet) between groups defined by income, age, geography, or education; a form of stratification with compounding effects on social mobility and political participation.

Social Stratification

• Definition — a system of structured inequality in which people are ranked in a hierarchy; three major systems: class (economic), caste (ascribed), estate (feudal); all societies exhibit stratification, though its form varies.
• Class — socioeconomic position; in Marx: bourgeoisie/proletariat; in Weber: class + status + party; in contemporary sociology: often measured by income, wealth, occupation, education.
• Social mobility — movement between strata; vertical (up or down) vs horizontal (lateral); intergenerational vs intragenerational; structural mobility driven by changes in the occupational structure.
• Baby boomers — the large demographic cohort born roughly 1946–1964, during the postwar surge in birth rates in the United States and other Western nations; their outsized generational size has shaped labor markets, housing, healthcare, and political culture at each life stage; in sociology and demography, the term anchors analysis of cohort effects, generational conflict, and the aging of developed-world populations.
• Caste system — rigid, ascribed stratification (e.g., India’s traditional caste system); little to no mobility.
• Estate system — feudal stratification: nobles, clergy, and commoners with legal distinctions.
• Meritocracy — the idea that stratification reflects individual talent and effort; contested as masking structural barriers.
• Poverty — absolute poverty: inability to meet basic survival needs; relative poverty: being poor relative to society’s average living standard; feminization of poverty: women are disproportionately poor globally.
• Pierre Bourdieu — economic capital (money), social capital (networks and relationships), cultural capital (education, tastes, credentials, manners); habitus: durable dispositions toward the world, shaped by one’s class position — not a habit but an internalized generative scheme that produces practices; field: a structured social arena of competition governed by its own rules (e.g., the academic field, the artistic field); Distinction (1984): class is reproduced through taste and cultural consumption; symbolic violence: the subtle imposition of dominant cultural categories as natural and legitimate.
• Davis-Moore thesis — Kingsley Davis and Wilbert Moore (1945): stratification is functionally necessary; higher rewards attached to important positions ensure qualified people compete to fill them; major target of conflict-theory critique (Melvin Tumin replied that it ignores inherited privilege).

Race and Ethnicity

• Race — a socially constructed category based on perceived physical differences; not a biological reality.
• Ethnicity — shared cultural identity (language, religion, ancestry, customs); distinct from race.
• Racism — individual, institutional, and structural forms; systemic racism: racism embedded in laws, policies, and institutions.
• Prejudice — a negative attitude toward a group; discrimination — unequal treatment based on group membership.
• Minority group (Louis Wirth) — a group subordinated by the dominant group, regardless of numerical size.
• Genocide, segregation, expulsion, assimilation, pluralism — a continuum of majority-minority relations.
• Assimilation — the process by which minority groups come to resemble the dominant group; melting pot vs multiculturalism/mosaic.

Gender and Sexuality

• Sex — biological (chromosomes, hormones, anatomy); gender — socially constructed identity and performance.
• Patriarchy — social systems in which men hold dominant power.
• Gender role socialization — children learn gendered expectations through family, school, media.
• Glass ceiling — invisible barriers preventing women and minorities from advancing to senior positions; glass escalator: men in female-dominated professions advance faster.
• Sexual orientation — the continuum of attraction; sociologists emphasize its social construction alongside its biological correlates.

Deviance and Social Control

• Deviance — violation of social norms; not inherently criminal; relative to culture and time; three major theoretical frameworks: strain/anomie (structural), labeling (interactionist), social bond/control (individual-level).
• Strain theory (Merton) — anomie occurs when cultural goals (wealth) are not matched by legitimate means; five adaptations: conformity, innovation, ritualism, retreatism, rebellion; innovation (accept goals, reject means — e.g., theft) and rebellion (reject both, substitute new) are most relevant to crime.
• Labeling theory — Howard Becker (Outsiders, 1963): deviance is not a quality of the act but a label applied by others; moral entrepreneurs campaign to have behaviors labeled deviant; Edwin Lemert: primary deviance (initial act) vs secondary deviance (identity reorganized around the label).
• Social control — formal (laws, police, courts) vs informal (peer pressure, shame, ostracism).
• Differential association theory (Edwin Sutherland) — deviance is learned through interaction with others who hold favorable definitions of illegal behavior; number, duration, priority, and intensity of associations determine whether crime is learned; also developed the concept of white-collar crime (crime by respectable persons in the course of their occupation).
• Social bond theory (Travis Hirschi) — Causes of Delinquency (1969): four bonds to conventional society deter deviance: attachment (care for others’ opinions), commitment (investment in conventional goals), involvement (time in conventional activities), belief (acceptance of norms).
• Routine activities theory (Cohen and Felson) — crime occurs when a motivated offender, a suitable target, and the absence of capable guardians converge in time and space; explains crime rates through everyday patterns rather than individual pathology.
• Medicalization of deviance — formerly moral or criminal behaviors redefined as medical problems (e.g., alcoholism, ADHD); Peter Conrad’s key contribution; expands medical jurisdiction and shifts blame from social structure to individual biology.

Institutions

• Social institution — an organized pattern of beliefs and behavior centered on meeting a basic social need; five major: family, education, religion, economy, government/polity.
• Family — nuclear (parents + children) vs extended; functionalist view: socialization, economic support, emotional support; conflict view: site of inequality; feminist view: site of patriarchy; symbolic interactionist view: negotiated meanings and roles; trends: rising cohabitation, declining marriage rates, rising single-parent households.
• Education — manifest functions: transmission of knowledge, credentialing; latent functions: socialization, social networking, custodial care; hidden curriculum: transmission of norms and values implicitly; credentialism: over-emphasis on degrees; tracking: sorting students into different academic pathways.
• Religion — Durkheim: the sacred vs the profane; religion creates social cohesion through shared rituals; Weber: the Protestant ethic; secularization thesis: modernization reduces religious authority; contested empirically.
• Economy — capitalism (private ownership, market allocation) vs socialism (collective ownership); post-industrial society (Daniel Bell): shift from manufacturing to service and information.
• Political sociology — the state’s monopoly on legitimate force (Weber); pluralism (power dispersed) vs elite theory (C. Wright Mills) vs class dominance theory (Marxist).

Demography and Urbanization

• Demography — the statistical study of populations; key variables: fertility, mortality, migration.
• Demographic transition model — four stages: (1) high birth + high death rates; (2) declining death rates, rapid growth; (3) declining birth rates; (4) low birth + low death rates; some add a Stage 5 (below-replacement fertility).
• Total fertility rate (TFR) — average number of births per woman over her lifetime; replacement-level TFR ~2.1.
• Malthusian theory — Thomas Malthus (1798): population grows geometrically while food supply grows arithmetically; predicted catastrophic check; criticized for ignoring technological change.
• Urbanization — shift from rural to urban living; urban ecology (Chicago School): cities grow outward in concentric zones (Burgess model); invasion-succession describes neighborhood change.
• Suburbanization / white flight — post-WWII movement of (often white, middle-class) families to suburbs; linked to residential segregation.
• Global cities (Saskia Sassen) — New York, London, Tokyo function as command-and-control centers of the global economy.
• Gentrification — higher-income residents displace lower-income residents in urban neighborhoods.

Classic Concepts and Terms

• Sociological imagination (C. Wright Mills) — The Sociological Imagination (1959): the ability to see the connection between personal troubles and public issues; to situate biography within history and social structure.
• Looking-glass self (Cooley) — self-concept formed through three steps: (1) imagining how we appear to others; (2) imagining their judgment; (3) developing feelings (pride or shame) in response.
• Dramaturgy (Goffman) — social life as theater; front stage (public performance), back stage (behind-the-scenes), props, costumes, and scripts shape impression management; The Presentation of Self in Everyday Life (1959).
• Total institutions (Goffman) — Asylums (1961): enclosed social environments (prisons, mental hospitals, military boot camps, monasteries) that control all aspects of life; strip residents of prior identity (mortification of self) and resocialize them; exemplify institutional power at its most total.
• Stigma (Goffman) — Stigma (1963): a spoiled identity resulting from a discrediting attribute; three types: tribal (race, ethnicity, religion), abomination of the body (physical differences), blemishes of individual character (mental illness, addiction, criminal record); stigmatized individuals use passing or covering to manage their identity.
• Cultural capital (Bourdieu) — knowledge, skills, and tastes that confer advantage; institutionalized (credentials), embodied (manners, speech), objectified (books, art).
• Thomas theorem (W.I. Thomas) — “If men define situations as real, they are real in their consequences” (1928); foundational for labeling theory and social constructionism.
• Iron cage (Weber) — modern bureaucratic capitalism traps individuals in a system of rational, rule-bound control; spiritual meaninglessness as a consequence.
• Reference group (Robert Merton / Herbert Hyman) — a group whose standards one uses to evaluate oneself; explains relative deprivation: feeling deprived relative to a reference group, not in absolute terms.
• Breaching experiments (Harold Garfinkel) — ethnomethodology: deliberately violating taken-for-granted norms to reveal the hidden rules sustaining social order; Garfinkel’s Studies in Ethnomethodology (1967); indexicality and reflexivity as properties of practical social action.
• Social construction of reality (Berger and Luckmann) — The Social Construction of Reality (1966): reality is produced through ongoing social interaction; institutionalization and legitimation stabilize shared meanings.
• Anomie (Durkheim / Merton) — Durkheim: normative deregulation during rapid social change (economic boom or bust) dissolves the constraints that ordinarily limit desires, producing malaise and suicide; Merton reapplied the concept to explain crime as a structural disjunction between culturally prescribed goals and institutionalized means.
• Double consciousness (Du Bois) — the “twoness” of being African American: always seeing oneself through the eyes of a white-dominated society as well as through one’s own; the veil as a metaphor for the barrier between Black and white America; first developed in The Souls of Black Folk (1903).
• Generalized other (Mead) — the internalized image of the attitudes and expectations of the community as a whole; taking the perspective of the generalized other is the fully developed form of role-taking; complements the I (spontaneous, creative self) and Me (socialized, reflexive self).
• Presentation of Self (Goffman) — full title The Presentation of Self in Everyday Life (1959); introduces the dramaturgical framework; impression management is how actors control information to sustain a desired definition of the situation; teams collaborate to maintain a consistent performance.
• Self-fulfilling prophecy (Merton) — a false definition of a situation that evokes behavior which makes the false conception come true; coined by Merton (1948); applied to racial stereotypes, educational tracking, and financial panics; depends on the Thomas theorem.
• Bowling Alone (Robert Putnam) — Bowling Alone (2000): civic engagement and social capital in the U.S. declined dramatically since the 1960s; Americans bowl more but in leagues less — a metaphor for individualized, unaffiliated leisure; causes include TV, suburbanization, and generational change; prescribes rebuilding bridging social capital.
• verify: Granovetter’s original “strength of weak ties” paper (1973) — confirm it was published in American Journal of Sociology vol. 78, and the key concept is bridging structural holes between otherwise disconnected clusters.
• verify: The Hawthorne studies were conducted at Western Electric’s Hawthorne Works in Cicero, Illinois (not Chicago) — confirm plant location and lead researchers (Elton Mayo is usually credited).
• verify: Wallerstein’s The Modern World-System vol. 1 was published in 1974 — confirm publisher (Academic Press) and that he was at SUNY Binghamton when he wrote it.

Research Methods

• Quantitative methods — surveys, statistical analysis, experiments; aim to generalize across populations; operationalization of variables required.
• Qualitative methods — ethnography, in-depth interviews, focus groups, content analysis; aim for interpretive depth; associated with symbolic interactionism and feminist methodologies.
• Ethnography — extended immersive fieldwork in a social setting; participant observation (researcher joins the group) vs non-participant observation.
• Survey research — structured questionnaires; random sampling allows inference to a population; issues: response bias, question wording effects, social desirability bias.
• Experiment — random assignment to treatment and control; rare in sociology outside social psychology; field experiments used for discrimination testing.
• Content analysis — systematic coding of texts, media, or documents.
• Mixed methods — combining quantitative and qualitative approaches; triangulation strengthens validity.
• Reliability — consistency of a measure. Validity — whether a measure captures what it claims to.
• Value-freedom (Wertfreiheit, Weber) — the sociologist should distinguish empirical facts from value judgments; contested in feminist and critical traditions.

Sociology vs Adjacent Fields

• Sociology vs psychology — psychology focuses on individual mind and behavior; sociology focuses on social structures, groups, and institutions. Social psychology bridges both.
• Sociology vs anthropology — cultural anthropology traditionally studied non-Western societies using ethnography; sociology focused on modern industrial societies; boundaries now blurred. Physical/biological anthropology is further afield.
• Sociology vs economics — economics assumes rational self-interest and focuses on markets; sociology emphasizes culture, power, and social context; economic sociology (Weber, Granovetter) embeds economic action in social relations.
• Sociology vs political science — political science focuses on governance, states, and formal institutions; political sociology examines the social bases of power and politics.
