MCAT PSYCHOLOGICAL, SOCIAL, & BIOLOGICAL FOUNDATIONS OF BEHAVIOR • FOUNDATIONAL CONCEPT 7: BEHAVIOR AND BEHAVIOR CHANGE

Social Norms, Deviance, and Sanctions (7B)

Understanding how societies regulate behavior through shared expectations, norm violations, and mechanisms of social control.

Historical Context & Motivation

The study of social norms, deviance, and sanctions constitutes one of the foundational pillars of sociology and social psychology, tracing its intellectual lineage to the earliest systematic attempts to understand how societies maintain order and cohesion. Long before these concepts were formalized in academic discourse, philosophers such as Thomas Hobbes and Jean-Jacques Rousseau grappled with the question of how individuals coordinate behavior in the absence of perpetual coercion. The emergence of sociology as a discipline in the nineteenth century crystallized these inquiries into empirical and theoretical frameworks that remain central to the MCAT's treatment of social and behavioral determinants of health.

1893
Durkheim's Division of Labor
Émile Durkheim published The Division of Labor in Society, introducing mechanical and organic solidarity as mechanisms through which collective norms bind individuals to society.
1938
Merton's Strain Theory
Robert K. Merton introduced strain theory, arguing that deviance arises from a disconnect between culturally prescribed goals and the institutionalized means available to achieve them, yielding five modes of adaptation.
1963
Becker's Labeling Theory
Howard Becker published Outsiders, formalizing labeling theory and asserting that deviance is not inherent in an act but is constructed through social reaction and the application of labels.
1969
Blumer's Symbolic Interactionism
Herbert Blumer codified symbolic interactionism, emphasizing that norms are negotiated through micro-level interactions and that meaning is constructed rather than discovered, profoundly influencing how deviance is conceptualized.
1975
Foucault's Discipline and Punish
Michel Foucault analyzed how modern institutions enforce conformity through surveillance and normalization, shifting the study of sanctions from purely legal mechanisms to diffuse networks of power.

These intellectual developments converge on a central question that the MCAT expects you to engage with at a sophisticated level: How do societies establish behavioral expectations, what happens when individuals transgress those expectations, and through what mechanisms does society respond to such transgressions? Understanding this triad—norms, deviance, and sanctions—is essential for comprehending how social structures shape individual health behaviors and outcomes, a theme that pervades the Psychological, Social, and Biological Foundations section.

Core Principles & Definitions

At the broadest level, social norms represent the shared rules and expectations that govern behavior within a group or society. These norms exist along a continuum from informal, largely unspoken guidelines to formally codified laws and regulations. The MCAT requires you to distinguish among several categories of norms, understand the relational nature of deviance, and appreciate the range of sanctions societies deploy to enforce conformity. The following core concepts form the foundation of this topic.

1

Folkways

Informal norms governing everyday behavior, such as table manners or greeting conventions. Violations produce mild social disapproval rather than severe punishment. William Graham Sumner introduced this term in 1906 to describe customs that arise from repetition and tradition.
2

Mores

Norms that carry significant moral weight and reflect core values of a society. Violations evoke strong social censure, as mores define what a community considers fundamentally right or wrong. Examples include prohibitions against dishonesty and norms surrounding sexual conduct.
3

Taboos

The strongest form of mores—behaviors that provoke extreme revulsion and are nearly universally condemned within a society. Incest prohibitions represent a cross-cultural example. Violations of taboos trigger severe formal and informal sanctions simultaneously.
4

Laws

Formally codified norms enforced by governmental authority. Laws carry prescribed penalties and represent the institutionalization of mores—or sometimes folkways—into binding legal structures. Not all mores become laws, and not all laws reflect current mores, which creates tension.
5

Deviance as Relational

Deviance is not an intrinsic property of an act but a label applied through social processes. What constitutes deviance varies across cultures, historical periods, and social contexts. This relational perspective, rooted in labeling theory, is essential for MCAT reasoning.
KEY TAKEAWAY
Think of social norms as the operating system of a society—they run in the background, invisible when everything works smoothly, but immediately noticeable when something crashes. Folkways are like minor software preferences (annoying when violated, but the system still runs), mores are like system-critical processes (violations cause serious errors), and laws are the hard-coded security protocols with automated enforcement. The key insight for the MCAT is that deviance is defined by the system context, not by the action itself—just as a perfectly valid command in one operating system may produce an error in another.

Visual Explanation: The Norm–Deviance–Sanction Cycle

This diagram illustrates the cyclical relationship among social norms, individual behavior, deviance, and sanctions. Social norms (top) establish behavioral expectations. When individuals violate these expectations, their behavior is labeled as deviance (right), which triggers sanctions (bottom right). Sanctions, in turn, feed back to reinforce, modify, or challenge the original norms. Conformity (green path, left) directly reinforces existing norms without triggering the deviance–sanction pathway.

The cyclical nature of this model is critical for MCAT reasoning. Social control is not a unidirectional process in which powerful institutions simply impose rules on passive individuals. Rather, individuals' conformity and deviance actively shape the normative landscape. When enough individuals deviate from a particular norm—as occurred with shifting attitudes toward same-sex marriage in the United States—the norm itself can transform, sanctions may be relaxed or reversed, and what was once deviant becomes normative. This dynamic quality of social norms underscores the sociological perspective that deviance is socially constructed rather than inherent in the act itself.

Mechanisms of Social Control: Formal vs. Informal

Social control refers to the processes by which societies regulate individual and group behavior. This regulation operates through two broad channels: formal social control and informal social control. Formal social control involves codified rules enforced by designated authorities—laws, regulations, and institutional policies backed by the state's monopoly on legitimate force. Informal social control, by contrast, operates through everyday social interactions: praise, ridicule, ostracism, gossip, and the internalized desire for social approval. Both mechanisms employ sanctions, which can be further classified along a positive–negative axis.

The Sanction Matrix: Formal/Informal × Positive/Negative

Classification of sanctions along two axes: formality and valence
Positive SanctionNegative Sanction
FormalAwards, promotions, degrees, tax incentives, official commendationsFines, imprisonment, license revocation, expulsion, military court-martial
InformalPraise, smiles, social inclusion, increased status, verbal affirmationGossip, ridicule, social exclusion, shaming, "cold shoulder" treatment

The MCAT frequently tests your ability to classify sanctions into these four quadrants. A question might describe a scenario—a physician being censured by a medical board—and ask you to identify the sanction type. In that case, the sanction is formal and negative because it involves an authorized institutional body imposing a consequence. Contrast this with a medical student's peers avoiding them after an ethical lapse—an informal negative sanction. The distinction rests on whether an institutionalized authority is administering the consequence.

Internalization: The Most Powerful Mechanism

Perhaps the most efficient form of social control is internalization—the process by which individuals adopt societal norms as their own values, rendering external enforcement largely unnecessary. Through socialization, agents such as family, education, religion, and media instill normative expectations that individuals come to experience as intrinsic moral convictions. When internalization is successful, the individual monitors and sanctions their own behavior through guilt, shame, or pride, effectively becoming both norm-follower and norm-enforcer simultaneously. Freud's conceptualization of the superego, Mead's notion of the generalized other, and Bourdieu's concept of habitus all converge on this principle of internalized social control.

💡 MCAT INSIGHT
Exam questions often present scenarios where no external enforcement is present yet individuals still conform to norms. The expected reasoning invokes internalization as the mechanism. Be prepared to distinguish internalization from compliance (conforming due to external pressure without private acceptance) and identification (conforming to maintain a relationship or social role).

Theoretical Perspectives on Deviance

The MCAT expects candidates to integrate multiple theoretical perspectives on deviance, understanding both how each perspective explains norm violation and where their explanatory power diverges. Four major theoretical frameworks dominate this domain: functionalist (strain) theory, labeling theory, differential association theory, and conflict theory. Each offers a distinct lens for analyzing why individuals or groups violate social norms.

Merton's five modes of adaptation illustrate how individuals respond when there is a gap between culturally valued goals and legitimate means. Conformity accepts both goals and means. Innovation accepts goals but rejects legitimate means, while ritualism abandons goals but rigidly follows means. Retreatism rejects both, and rebellion seeks to replace both with new alternatives.

Labeling Theory and the Deviance Amplification Spiral

While strain theory focuses on structural conditions that produce deviance, labeling theory shifts attention to the social processes that define certain acts—and certain people—as deviant. Edwin Lemert distinguished between primary deviance (initial norm violations that have minimal impact on self-concept) and secondary deviance (deviance that becomes central to identity after societal labeling). Once an individual is labeled as deviant—for instance, being formally adjudicated as a 'criminal'—the label triggers a self-fulfilling prophecy in which the person internalizes the deviant identity, faces reduced legitimate opportunities, and becomes more likely to engage in further deviance. This process, known as the deviance amplification spiral, has profound implications for understanding health disparities, mental health stigma, and substance use disorders—all topics within the MCAT's scope.

Differential Association and Conflict Perspectives

Edwin Sutherland's differential association theory posits that deviant behavior is learned through interaction with intimate personal groups. Individuals become deviant when they are exposed to an excess of definitions favorable to norm violation over definitions unfavorable to it. This theory emphasizes that deviance is not a product of individual pathology but of normal social learning processes operating in particular social environments. From a conflict theory perspective, norms and their enforcement reflect the interests of dominant groups. Laws and formal sanctions disproportionately target behaviors associated with marginalized populations, while equally harmful behaviors by those in power may be normalized or go unsanctioned. This perspective draws on Marx's analysis of class relations and is exemplified in studies showing racial and socioeconomic disparities in criminal justice outcomes.

Worked Example: Analyzing a Clinical Scenario

The following worked example illustrates how to apply the concepts of social norms, deviance, and sanctions to a passage-based MCAT question. This type of reasoning integrates multiple theoretical frameworks and requires you to classify sanctions and identify the operative mechanisms of social control.

MCAT-Style Scenario Analysis
1
Step 1 — Read and Identify the ScenarioA passage describes a rural community where a physician begins offering medication-assisted treatment (MAT) for opioid use disorder. Community members circulate petitions, refuse to patronize the physician's practice, and the local newspaper publishes editorials criticizing the treatment as 'enabling addiction.' The physician's medical license remains unaffected. The question asks: What type of social control is operating against the physician?
2
Step 2 — Classify the Norm Being EnforcedThe community holds a norm—likely a more—that drug addiction should be addressed through abstinence rather than pharmacological intervention. This norm carries moral weight within the community but is not codified in law, as MAT is legal and evidence-based.
The norm is an informal more, not a law.
3
Step 3 — Identify the Type of DevianceThe physician's behavior constitutes deviance within this specific community context, even though it aligns with professional medical norms. This illustrates the relational, context-dependent nature of deviance as described by labeling theory—the same behavior may be normative in one setting and deviant in another.
Deviance is context-dependent: normative in medicine, deviant in this community.
4
Step 4 — Classify the SanctionsThe petitions, loss of patronage, and editorials are all forms of informal negative sanctions. They are negative because they impose costs (reputational damage, financial loss), and informal because they are administered by community members rather than governmental or institutional authorities. The key detail that the physician's license is unaffected confirms no formal sanctions are present.
Answer: Informal negative sanctions — community-driven punishment without institutional authority.
5
Step 5 — Consider the Broader ImplicationsFrom a conflict theory lens, the community's response may reflect power dynamics in which certain groups define 'appropriate' treatment based on moral rather than empirical grounds. From a functionalist perspective, the sanctions serve to maintain social cohesion by enforcing shared values. An effective MCAT response would recognize that the correct answer (informal negative sanctions) does not endorse the community's position but merely classifies the sociological mechanism at work.

Comparing Theoretical Perspectives on Deviance

Each major theoretical perspective on deviance offers distinct explanatory strengths and limitations. For MCAT preparation, the ability to rapidly identify which theory best explains a given scenario is essential. The following table synthesizes the four primary theories and highlights their key differences.

Comparative analysis of four major theories of deviance tested on the MCAT
TheoryCore ClaimLevel of AnalysisStrengthLimitation
Strain Theory (Merton)Deviance arises from a gap between cultural goals and legitimate meansMacro-structuralExplains class-based patterns in deviance; integrates structural inequalityAssumes shared cultural goals; difficulty explaining deviance among privileged groups
Labeling Theory (Becker, Lemert)Deviance is created through social labeling processes, not inherent in actsMicro-interactionalExplains stigma, secondary deviance, and self-fulfilling propheciesCannot explain why initial (primary) deviance occurs; may minimize harm of certain acts
Differential Association (Sutherland)Deviance is learned through social interaction with deviant peersMeso-level (groups)Explains peer influence, gang behavior, subcultural devianceDifficulty explaining solitary deviance; does not account for structural conditions
Conflict Theory (Marx, Chambliss)Norms and laws reflect dominant group interests; deviance is politically constructedMacro-structuralExplains differential enforcement, racial/class disparities in criminal justiceMay overemphasize class conflict; difficulty explaining norms with broad consensus
KEY TAKEAWAY
On the MCAT, deviance questions rarely ask you to choose the 'right' theory in the abstract. Instead, they present a specific scenario and ask which theory best explains the observed pattern. Strain theory is your best fit when the passage emphasizes blocked opportunities and socioeconomic inequality. Labeling theory applies when the passage focuses on how someone is perceived or stigmatized after an initial act. Differential association is cued by descriptions of peer influence or subcultural learning. Conflict theory is indicated by descriptions of power differentials, selective law enforcement, or class-based inequities in sanctions.

Connections to Medicalization, Stigma, and Health Disparities

The concepts of social norms, deviance, and sanctions extend directly into several advanced domains that the MCAT frequently tests: the medicalization of deviance, stigma, and their downstream effects on health disparities. Medicalization refers to the process by which previously non-medical problems become defined and treated as medical conditions—a transformation that reframes deviance from moral failing to illness. Historically, homosexuality was classified as a psychiatric disorder in the DSM until 1973; its declassification illustrates how medical categories are socially constructed and subject to normative shifts. Contemporary debates around the medicalization of ADHD, obesity, and chronic pain similarly exemplify this dynamic.

Mapping basic 7B concepts to advanced MCAT applications
ConceptBasic Application (7B)Advanced Application
Social NormsClassifying folkways, mores, taboos, and laws; recognizing cultural variationSick role norms (Parsons); physician–patient power dynamics; health behavior norms in epidemiology
DevianceIdentifying strain theory modes; distinguishing primary from secondary devianceMedicalization of deviance; mental illness stigma as barrier to treatment-seeking; intersectional analysis of who gets labeled deviant
SanctionsClassifying formal/informal and positive/negative sanctionsInstitutional discrimination as systemic sanction; social determinants of health as consequences of differential sanctioning across race and class

Erving Goffman's influential work on stigma (1963) is directly relevant to this intersection. Goffman defined stigma as a deeply discrediting attribute that reduces a person 'from a whole and usual person to a tainted, discounted one.' Stigmatized identities—whether related to mental illness, disability, criminal history, or substance use—function as forms of deviant labeling that trigger ongoing informal negative sanctions. These sanctions, in turn, produce measurable health effects: reduced care-seeking, chronic stress through stereotype threat and identity threat, and structural barriers to healthcare access. Understanding this chain—norm → deviance label → sanction → health disparity—represents the highest level of integration the MCAT expects within this content domain.

Practice Problems

PROBLEM 1CONCEPTUAL
A sociologist observes that jaywalking is technically illegal in a downtown area but is practiced by virtually all pedestrians without consequence. Local police officers jaywalk themselves. How would a sociologist classify jaywalking in this context, and what does this example illustrate about the relationship between laws and norms?
PROBLEM 2BASIC CALCULATION
Using Merton's strain theory, classify the following individual's mode of adaptation: A college graduate who aspires to financial success (a culturally valued goal) but, unable to find employment commensurate with her education, begins selling counterfeit designer goods online. Justify your classification.
PROBLEM 3INTERMEDIATE
A teenager is caught shoplifting once and is brought to juvenile court, where a judge labels him a 'juvenile delinquent.' Following this labeling event, the teenager begins associating exclusively with peers who engage in criminal behavior, eventually committing more serious offenses. Which two theories of deviance best explain this trajectory, and how do they complement each other?
PROBLEM 4APPLIED
A public health researcher finds that patients diagnosed with schizophrenia in a particular community are significantly less likely to seek follow-up care after their initial diagnosis, compared to patients diagnosed with diabetes. The researcher hypothesizes that the social consequences of the schizophrenia label are driving this disparity. Using concepts from this lesson, construct a sociological explanation for this health outcome. Identify the relevant norms, the type of deviance involved, and the sanctions that mediate the observed effect.
PROBLEM 5CRITICAL THINKING
A conflict theorist and a functionalist are debating the social significance of incarceration for drug offenses. The conflict theorist argues that drug laws function primarily to control marginalized populations, while the functionalist argues that drug sanctions serve to affirm shared moral boundaries. Using your understanding of norms, deviance, and sanctions, evaluate both positions. Under what conditions might each perspective be more explanatorily powerful? Can the two perspectives be reconciled, and if so, how?

Lesson Summary

Social norms are the shared rules governing behavior in a society, ranging from informal folkways (everyday customs provoking mild disapproval when violated) through morally weighted mores and extreme taboos to formally codified laws. Deviance is not an intrinsic property of an act but a socially constructed label that varies across cultures, historical periods, and social contexts. Four major theories explain deviance on the MCAT: strain theory (Merton's five modes of adaptation arising from goals–means gaps), labeling theory (primary vs. secondary deviance and the deviance amplification spiral), differential association theory (deviance learned through peer interaction), and conflict theory (norms and sanctions reflecting dominant group interests).

Sanctions are classified along two dimensions: formal vs. informal (institutional authority vs. everyday social interaction) and positive vs. negative (reward vs. punishment). The most efficient mechanism of social control is internalization, through which norms become self-enforced personal values. These concepts connect directly to MCAT-relevant advanced topics including the medicalization of deviance, stigma (Goffman), and the pathway from deviant labeling through informal negative sanctions to measurable health disparities—the norm → label → sanction → health outcome chain that represents the highest level of integration expected on the exam.
