Culture is the shared system of meanings, artifacts, and practices that shape how members of a society perceive, interpret, and interact with the world. The MCAT tests culture as both a lens for understanding individual behavior (the sociological perspective) and a structural force that reproduces inequality. You must distinguish between the tangible artifacts of material culture and the invisible rules of nonmaterial culture, recognize how ethnocentrism biases perception, and trace how cultural elements diffuse across societies — from the spread of democratic norms to the global reach of fast food. Culture is the foundational concept of the Psychological, Social, and Biological Foundations of Behavior section, anchoring topics on socialization, social stratification, and demographic change.
The college version
Material and Nonmaterial Culture
Culture has two inseparable layers. Material culture consists of physical objects and artifacts: tools, clothing, architecture, technology, and art — everything from a smartphone to a wedding ring. These objects carry meaning; a diamond ring is not just carbon but a symbol of commitment. Nonmaterial culture encompasses the intangible: values, beliefs, norms, language, symbols, and ideologies. Language is the most powerful nonmaterial element because it structures thought itself — the Sapir-Whorf hypothesis (linguistic relativity) proposes that language shapes perception, so speakers of different languages literally experience the world differently. Material and nonmaterial culture are interdependent: the smartphone (material) embeds values of constant connectivity (nonmaterial), while the belief in individualism (nonmaterial) shapes architectural designs like open-plan offices (material).
Cultural Norms, Values, and Beliefs
Values are a society's abstract ideals about what is good, right, and desirable (e.g., freedom, equality, education). Beliefs are the specific convictions people hold to be true (e.g., 'hard work leads to success'). Norms are the social rules that translate values into expected behavior. Norms range along a spectrum of severity: folkways are informal, loosely enforced conventions (dress codes, table manners); mores (pronounced MOR-ayz) carry moral weight and provoke stronger reactions when violated (honesty, fidelity); laws are formally codified and state-enforced norms; and taboos are the most extreme prohibitions whose violation is unthinkable (incest, cannibalism). Sanctions — both positive (praise, promotion) and negative (ridicule, imprisonment) — enforce norm compliance. The distinction between folkways and mores is a classic MCAT contrast: violating a folkway earns a raised eyebrow; violating a more sparks outrage.
Cultural Relativism and Ethnocentrism
Ethnocentrism is the tendency to judge other cultures by the standards of one's own, viewing one's own culture as normal or superior. It is nearly universal — everyone is socialized into a particular cultural framework — but it blinds observers to the internal logic of other cultural systems. Cultural relativism, a methodological stance pioneered by Franz Boas, insists that a culture must be understood on its own terms, without imposing external value judgments. The MCAT tests this tension through passages about cross-cultural research, medical practices, or family structures. Key nuance: cultural relativism is a tool for understanding, not a moral endorsement of all practices. Xenocentrism — the belief that another culture is superior to one's own — is the inverse of ethnocentrism and also distorts perception.
Subcultures and Countercultures
Societies are not culturally uniform. A subculture is a group whose values, norms, and practices differ from the dominant culture in distinct but compatible ways — ethnic neighborhoods, occupational groups (physicians, skateboarders), religious communities, or age-based groups (teenagers). Subcultures participate in the larger society while maintaining their own identity markers. A counterculture goes further: it actively rejects and opposes dominant cultural values. The 1960s hippie movement rejected consumerism and traditional authority; the punk movement rejected polished commercialism. The MCAT distinguishes these by degree of opposition: subcultures coexist; countercultures confront. Cultural appropriation — the adoption of subcultural elements by the dominant culture, often stripping them of context — is an emerging high-yield tension point.
Cultural Change and Diffusion
Culture is dynamic, not static. Change occurs through invention (creating new cultural elements, like the internet), discovery (uncovering previously unknown aspects of reality, like a new species), and diffusion (the spread of cultural elements across societies). Diffusion can be direct (trade, migration) or indirect (media, the internet). Key mechanisms: cultural lag (Ogburn) describes the gap when material culture changes faster than nonmaterial culture can adapt — we had smartphones for years before developing norms about when it is rude to check one. Cultural leveling is the process by which cultures become increasingly similar through globalization, often erasing local distinctiveness. Assimilation is the process by which minority groups adopt the dominant culture's norms, while multiculturalism promotes retention of distinct cultural identities within a shared society.
Globalization and Cultural Diversity
Globalization — the intensification of worldwide social and economic interdependence — accelerates cultural diffusion at unprecedented speed. It produces contradictory effects: cultural homogenization (the spread of common products, brands, and practices — McDonald's in Mumbai, K-pop in Kansas) coexists with cultural hybridization (the blending of elements into new, syncretic forms — Tex-Mex cuisine, Spanglish). Glocalization describes how global products are adapted to local contexts (McDonald's McAloo Tikki burger in India). The MCAT asks you to analyze how globalization affects identity: some groups embrace cosmopolitanism (world citizenship), others double down on local traditions in a defensive reaction called cultural revitalization. Cultural diversity within societies raises questions about multicultural policy, language preservation, and whether shared values are necessary for social cohesion.
How it works
Culture operates as both a lens and a script. As a lens, it filters perception: ethnocentrism is the default setting because culture is learned so early it feels like reality itself. As a script, it provides the norms and values that guide behavior — folkways at the surface, taboos at the deepest level. Cultural elements diffuse through contact: trade routes carried Buddhism from India to China; social media now carries memes globally in minutes. When material culture changes rapidly, nonmaterial culture lags behind (cultural lag), creating periods of normlessness that Durkheim called anomie. Globalization compresses this dynamic, bringing diverse cultures into constant contact and generating both creative fusion and conflict over whose norms should prevail.

Comparisons
- Socialization (Sociology): Culture is transmitted through socialization — families, schools, peers, and media teach children the norms, values, and beliefs of their society. The looking-glass self (Cooley) and role-taking (Mead) depend on shared cultural meanings.
- Social Stratification: Dominant cultural values often reflect the interests of powerful groups — Bourdieu's cultural capital (knowledge, tastes, credentials) reproduces class advantage. The MCAT tests how cultural practices maintain inequality.
- Demographics: Migration introduces cultural diversity, creating questions about assimilation versus multiculturalism. Cultural diffusion maps onto migration patterns — push and pull factors carry cultural elements across borders.
- Biology: Neuroscience informs the Sapir-Whorf hypothesis — does linguistic structure actually shape neural processing? Cross-cultural studies of perception test whether culture alters basic cognitive processes.
- Psychology (Cross-Cultural): The MCAT emphasizes cultural competence in clinical settings and research methodology. Ethnocentrism can invalidate cross-cultural studies if instruments are not validated across cultures.
Common confusions
- Cultural relativism means approving of all cultural practices. Cultural relativism is a methodological tool for understanding, not a moral position. You can understand a practice on its own terms while still holding ethical objections to it. The MCAT tests this with scenarios about harmful cultural practices and asks whether understanding requires endorsement.
- Folkways and mores are interchangeable. Folkways are informal conventions (etiquette, dress); mores are morally weighted norms (honesty, fidelity). Violating a folkway draws a raised eyebrow; violating a more provokes moral outrage. Look for the strength of social reaction in the passage.
- Subcultures and countercultures are the same thing. Subcultures differ from but coexist within the dominant culture (skateboarders, physicians). Countercultures actively oppose dominant values (hippies rejecting consumerism, militia groups rejecting government authority). The MCAT distinguishes by the presence or absence of active opposition.
- Diffusion always flows from dominant to non-dominant cultures. Cultural diffusion is multidirectional. Jazz and rock and roll originated in African American subcultures before diffusing to the dominant culture. The MCAT may present passages where minority cultural innovations are adopted by the mainstream.
- Material and nonmaterial culture are independent. They are intertwined — every material artifact carries nonmaterial meanings, and every value or belief is embedded in material practices and objects. Questions may ask you to identify the nonmaterial meaning encoded in a described material object (a wedding ring as a symbol of commitment).
- Globalization just makes cultures the same. Globalization produces both homogenization (common products and practices) and hybridization (new blended cultural forms). Look for passages that present both effects simultaneously — a local adaptation of a global product, or resistance movements emerging alongside cultural diffusion.
Quick review
- Material culture (physical objects, artifacts) vs. nonmaterial culture (values, beliefs, norms, language). Sapir-Whorf hypothesis: language shapes perception and thought.
- Norms spectrum: folkways (informal, weak sanctions) → mores (moral weight, strong reactions) → laws (codified, state-enforced) → taboos (unthinkable violations). Sanctions: positive and negative.
- Ethnocentrism (judging other cultures by one's own standards) vs. cultural relativism (understanding on the culture's own terms). Xenocentrism: belief that another culture is superior.
- Subculture: distinct group within dominant culture (coexists). Counterculture: actively opposes dominant values (confronts).
- Cultural change mechanisms: invention, discovery, diffusion. Cultural lag (Ogburn): material culture changes faster than nonmaterial culture. Cultural leveling: societies become increasingly similar.
- Globalization effects: homogenization (spread of common practices), hybridization (blended new forms), glocalization (global adapted to local). Cultural revitalization: defensive reaffirmation of local traditions.
- Assimilation (minority adopts dominant norms) vs. multiculturalism (retention of distinct identities). Cultural capital (Bourdieu): non-economic resources (knowledge, tastes, credentials) that confer status and reproduce class advantage.

Eli explains
The same idea, in plain words
Explain it like I’m 10
Imagine you move to a new country where everyone stands exactly six inches apart while talking, eats dinner at midnight, and considers eye contact rude. Your instinctive reaction — 'that's weird' — is ethnocentrism: judging their culture by your home country's standards. Their way makes perfect sense in their context (maybe it is a warm climate, or their work schedules differ). That recognition is cultural relativism: understanding on their terms. The physical distance, mealtimes, and eye-contact rules are nonmaterial culture (norms and values). Their distinctive clothes, cooking tools, and buildings are material culture. Now imagine a group of teenagers in that country who reject the midnight dinner norm and eat at 6 PM instead — they are a counterculture, not just a subculture, because they are actively opposing the dominant norm. Over time, if enough people adopt 6 PM dinners through restaurant chains and TV shows, that is cultural diffusion driving cultural change. If everyone around the world eventually eats at the same time, that is cultural leveling through globalization.
