Culture

Culture encompasses the entire lifestyle of a given group — it's what makes human societies unique from one another. Sociologists study culture through ethnography, the study of cultures, and break it down into two broad categories: material culture (the tangible items a group produces) and symbolic culture (the ideas that underlie those items). This article covers both categories, the role of language in transmitting culture, the values/beliefs/norms/rituals framework, and the evolutionary function culture may have played in early human societies.

Key Takeaways

• Culture encompasses a group's entire lifestyle and is studied through ethnography.

• Material culture consists of tangible artifacts (clothing, tools, buildings); symbolic (nonmaterial) culture consists of the underlying ideas those artifacts represent (mottoes, songs, values).

• Symbolic culture changes more slowly than material culture, producing culture lag (Ogburn).

• Language is the most complex symbol system culture relies on for transmission; written language crosses both space and time.

• Values (what matters), beliefs (what's accepted as true), norms (what's acceptable to do), and rituals (formalized performances of all three) together structure behavior within a culture; cultural barriers arise when cultural differences impede interaction.

• Culture likely conferred evolutionary advantages — transmitting practical knowledge, reinforcing loyalty and altruism, and shaping in-group/out-group dynamics.

• Lactase persistence is a textbook example of gene-culture coevolution: several dairying populations (Northern European, and separately Fulani, Maasai, and Arabian Bedouin) independently evolved the ability to digest lactose into adulthood, driven by their own cultural practice of dairy farming.

Material and Symbolic Culture

Material Culture

Material culture consists of artifacts — material items that are made, possessed, and valued by a group. Much can be discerned about a group of people by examining their artifacts, since concept is the basis behind material culture: every artifact reflects an underlying idea. Material culture includes the physical items associated with a given group — artwork, emblems, clothing, jewelry, foods, buildings, and tools — and is often most visible during ceremonies like birthdays, weddings, and funerals.

Symbolic Culture (Nonmaterial Culture)

Symbolic culture, or nonmaterial culture, focuses on the ideas that represent a group of people — mottoes, songs, or catchphrases. Material culture is often the tangible embodiment of the underlying ideas of symbolic culture: a flag (material) embodies national loyalty (symbolic); a wedding ring (material) embodies a marriage vow (symbolic). Culture is needed to bind a social group together over a significant period of time.

Governments often use symbolic culture to rally people to action during times of crisis — songs, parades, and hero discussions. Schools rely on the same mentality: mascots, school colors, and a school song exist to help create a shared sense of identity. Symbolic culture has both cognitive and behavioral aspects — it informs cultural values and beliefs, and it informs cultural norms and communication styles.

Symbolic culture is usually slower to change than material culture. This difference in pace creates culture lag, a term coined by sociologist William F. Ogburn — a gap where a society's material or technological changes outpace the symbolic culture (norms, laws, values) needed to adapt to them.

MCAT Callout — Material culture vs. symbolic culture: these aren't two unrelated categories — they're two layers of the same thing. Material culture is the tangible, observable layer (objects, artifacts); symbolic culture is the underlying layer of ideas those objects represent. A vignette describing a physical object (a flag, a uniform, a religious icon) is invoking material culture; a vignette describing the meaning, loyalty, or identity behind that object is invoking symbolic culture. Culture lag is what happens when the two layers change at different speeds — new material culture without a symbolic culture that's caught up to it yet.

Language

Language is the most highly developed and complex symbol system used by most cultures. It enables people to share thoughts, ideas, experiences, discoveries, fears, plans, and desires. Written language, in particular, transcends both spatial and temporal boundaries — it can travel across distance and persist across time in a way spoken language alone cannot.

It would be difficult to transmit culture without language: to understand a group's language is to take a major step toward understanding their culture.

Values, Beliefs, Norms, and Rituals

Four related concepts describe how symbolic culture shapes behavior day to day:

• Values — what a person deems important in life. Values dictate ethical principles and standards of behavior.

• Beliefs — something an individual accepts to be truth.

• Norms — societal rules that define the boundaries of acceptable behavior. Norms govern the behavior of society and provide a sense of social control; they exist for behavior, speech, dress, home life, and more.

• Rituals — formalized ceremonies that involve specific material objects, symbolism, and additional mandates on acceptable behavior. Rituals can be associated with specific milestones, with holidays, or with regular activities.

When cultural differences impede interaction between groups or individuals, that friction is called a cultural barrier.

MCAT Callout — Value vs. belief vs. norm: these three are easy to blur together because they all shape behavior, but they answer different questions. A value answers "what matters to me?" A belief answers "what do I accept as true?" A norm answers "what is acceptable to do, here, in this group?" A ritual is where all three get performed together — a formalized event built around a group's values, beliefs, and norms.

Evolution and Human Culture

Culture likely conferred real evolutionary benefits on early human societies. In prehistoric times, culture most likely served as a conduit for teaching future generations how to create tools, hunt, domesticate animals, and grow crops. It also created a sense of loyalty and allegiance, which may help explain altruistic behavior — acting in ways that benefit others at a cost to oneself. And it created a sense of "us vs. them," which may have played a role in the dispersion of human populations across the globe.

There's also evidence that some genetic traits were favored based on cultural values and practices — a phenomenon known as gene-culture coevolution. The clearest example: most mammals, including most humans worldwide, lose the ability to digest lactose (milk sugar) after weaning. But several human populations with a long history of dairy farming evolved a trait called lactase persistence, which allows them to keep digesting lactose into adulthood. This isn't limited to one population — lactase persistence evolved independently in Northern Europeans as well as in several African and Middle Eastern pastoralist populations with their own dairying traditions, such as the Fulani, Maasai, and Arabian Bedouin. In each case, a cultural practice (raising dairy animals) shaped which genetic traits were selected for over generations — culture and biology evolving together.

Why Culture Matters for the MCAT

MCAT questions on culture typically describe a scenario and ask you to identify which cultural concept it illustrates:

• Sort a described item or practice into material or symbolic culture. A physical object is material culture; the idea or meaning behind it is symbolic culture.

• Recognize culture lag when a passage describes technology, laws, or material conditions changing faster than the norms or values that govern them.

• Distinguish value, belief, norm, and ritual by the question each answers — importance, truth, acceptable behavior, or formalized performance.

• Recognize gene-culture coevolution when a passage links a cultural practice to a genetic trait's selection, like dairy farming and lactase persistence — don't reduce it to "humans are unique," since the trait varies by population and practice, not by species-wide uniqueness.

Common MCAT Mistakes

• Calling a physical object's meaning "material culture." The object itself (a flag, a wedding ring) is material culture; the loyalty or vow it represents is symbolic culture. Don't label the idea layer with the material term.

• Treating culture lag as "culture changing over time" in general. Culture lag specifically means symbolic culture (norms, laws, values) trailing behind material or technological change — not just change happening at some pace.

• Confusing a norm with a ritual. A norm is the underlying rule ("don't speak during a ceremony"); a ritual is the formalized event built around that rule and others, tied to a milestone, holiday, or recurring activity.

• Assuming lactase persistence is a universal human trait. It's population-specific — tied to a history of dairy farming — not something all humans, or humans as a species, uniquely have. Most mammals, and many human populations, lose lactase after weaning.

MCAT-Style Concept Check

Question: A country rapidly adopts a new genetic testing technology, but its laws and ethical guidelines governing consent and data privacy for that technology remain unchanged for years afterward. This scenario best illustrates:

• A) Culture lag

• B) Gene-culture coevolution

• C) A cultural barrier

• D) A ritual

Answer: A

Explanation: The new testing technology is material/technological culture, and the unchanged laws and ethical guidelines are symbolic culture (norms and values). The gap between the two — technological change outpacing the symbolic culture needed to govern it — is the definition of culture lag. Gene-culture coevolution (B) describes a cultural practice shaping which genetic traits get selected for, not a mismatch in rate of change. A cultural barrier (C) describes friction between groups with different cultures, not a society's own internal lag. A ritual (D) is a formalized ceremony, not a description of institutional or legal delay.

FAQ

What's the difference between material culture and symbolic culture?

Material culture is the tangible layer — artifacts like artwork, clothing, buildings, and tools. Symbolic (nonmaterial) culture is the underlying layer of ideas those artifacts represent, like mottoes, songs, and values. Material culture is often the physical embodiment of a symbolic idea, not a separate, unrelated category.

What is culture lag, and who coined the term?

Culture lag is the gap that opens up when a society's material or technological changes outpace the symbolic culture (norms, laws, values) needed to adapt to them. The term was coined by sociologist William F. Ogburn.

How do values, beliefs, norms, and rituals differ?

A value is what a person deems important and dictates ethical principles. A belief is something an individual accepts as truth. A norm is a societal rule defining acceptable behavior. A ritual is a formalized ceremony that performs a group's values, beliefs, and norms together, often tied to a milestone, holiday, or recurring activity.

What is gene-culture coevolution, and what's the classic example?

Gene-culture coevolution is when a cultural practice shapes which genetic traits are favored by natural selection over generations. The classic example is lactase persistence: several populations with a long history of dairy farming — Northern Europeans, and independently the Fulani, Maasai, and Arabian Bedouin — evolved the ability to digest lactose into adulthood, driven by their own dairying traditions.
