Deviance describes a social relationship to rules
In sociology, deviance refers to behavior or characteristics defined as violating social norms or expectations. The label depends on social context: rules vary across groups, settings, and historical periods. Calling something deviant therefore does not mean it is biologically abnormal, immoral, or a psychiatric diagnosis.
The useful MCAT question is usually why a pattern occurs or how society responds to it. Competing theories emphasize different mechanisms, so the evidence needed to support them differs.
Concept: different theories predict different patterns
Differential association emphasizes learning definitions, techniques, and norms favorable to rule-breaking through interaction with others. Evidence of increasing exposure to peers who model and reinforce a behavior is therefore especially relevant.
Strain theory emphasizes tension between socially valued goals and unequal access to legitimate means of reaching them. Evidence about blocked opportunities, institutional barriers, or pressure to achieve culturally valued outcomes is central to that explanation.
Labeling theory focuses on how social reactions and labels can alter identity, treatment, and future opportunities. It does not claim that a label creates every original rule violation. Instead, it asks what happens after people and institutions define someone in a particular way.
Worked application: one violation, four pieces of evidence
An original longitudinal vignette follows students at a fictional school after one student, R, is caught falsifying a club attendance record. Researchers collect four observations over the next year.
| Observation | Evidence | Most directly relevant theory |
|---|---|---|
| 1 | Before the violation, R increasingly spent time with peers who described falsifying records as normal and demonstrated how to avoid detection. | Differential association |
| 2 | Access to a competitive scholarship required an activity threshold that R could not meet because paid work limited after-school availability. | Strain |
| 3 | After the incident, teachers repeatedly described R as “untrustworthy,” including in settings unrelated to the original violation. | Labeling |
| 4 | R was later excluded from several leadership opportunities despite no additional rule violations. | Possible consequence of labeling |
The observations do not require choosing one theory to explain every event. Peer exposure supports a social-learning account of how the behavior could be learned. Blocked legitimate opportunities support a strain-based explanation. The later institutional treatment is evidence about the consequences of a deviant label.
This is an important reasoning habit: theories can address different causal stages rather than being mutually exclusive descriptions of an entire life history.
Pattern: labels can change opportunities after the original event
Suppose two students commit the same first-time rule violation, but only one receives a formal “high-risk” designation visible to teachers. If the labeled student is subsequently excluded from programs at a much higher rate despite matched later behavior, that comparison supports the claim that the label affected opportunities.
It still would not prove that the label caused all later behavior. To make that claim, a study would need to distinguish the effects of the label from prior differences, later peer exposure, institutional responses, and other changing conditions.
Labeling theory is therefore about a social process, not a statement that people inevitably become whatever others call them.
Rule: collective behavior is not the same as a social movement
Collective behavior can describe relatively spontaneous or loosely organized shared behavior, including fads, crowd responses, or rapid collective reactions. A social movement is more organized and sustained, usually oriented toward promoting or resisting social change.
A large crowd is not automatically a movement. If a transient reaction fades once an event ends and has no continuing organization, leadership, resources, or campaign strategy, collective behavior is the better description. If participants build durable organizations and pursue policy or cultural change over time, the evidence fits a social movement more closely.
Historical terms sometimes used for dramatic crowd reactions should be interpreted in context rather than used as dismissive clinical labels for groups.
ACTIVE PRACTICE · EVIDENCE AND TRANSFER
Locate Social-Learning, Strain, and Labeling Evidence in Time
The lesson follows student R across one attendance-record violation. Before the incident, peers normalize falsification and paid work limits the extracurricular threshold needed for a scholarship. After the violation, teachers repeatedly label R ‘untrustworthy’; later leadership access declines despite no new violation.
Examine the comparison and its limitations
Original instructional comparisons establish observed counts, categories, or associations. Causal mechanisms and individual attributes require separately appropriate evidence.

Check 1
Researchers compare two otherwise similar settings. In Setting A, blocked access to a valued educational goal is high but peer approval of rule-breaking is low. In Setting B, legitimate opportunities are available but peer groups teach and reward the rule-breaking behavior. Which contrasting prediction best distinguishes strain theory from differential association?
A. Strain predicts more rule-breaking in A, whereas differential association predicts more in B.
Correct. The theories emphasize different mechanisms: blocked legitimate means versus socially learned definitions and techniques.
B. Both theories predict identical behavior regardless of opportunity or peer exposure.
Review this choice. The point of the comparison is that the theories make different mechanism-based predictions.
C. Labeling theory alone predicts both patterns before any social reaction occurs.
Review this choice. Labeling theory primarily concerns social reactions and their consequences rather than these two pre-violation mechanisms.
D. Neither theory can generate a prediction from the supplied evidence.
Review this choice. The conditions were designed to isolate the mechanisms emphasized by the two theories.
Check 2
Two people have identical later behavior, but the person formally labeled “delinquent” is denied more jobs and school opportunities. Which claim is best supported?
A. The social label is associated with changed opportunities.
Correct. The outcome differs despite matched later behavior.
B. The label proves a permanent personality trait.
Review this choice. A social classification does not establish an intrinsic trait.
C. The original behavior was caused by the label.
Review this choice. The label followed the original event.
D. Opportunity differences cannot be studied sociologically.
Review this choice. Institutional treatment is a sociological outcome.
Check 3
A crowd rapidly adopts a fashion trend after a celebrity event, but there is no lasting organization or effort to change institutions. Which term fits best?
A. Collective behavior
Correct. The response is shared but transient and loosely organized.
B. A formal social movement
Review this choice. Sustained organization and change-oriented activity are absent.
C. Bureaucracy
Review this choice. No formal administrative hierarchy is described.
D. Primary socialization
Review this choice. The scenario concerns a transient collective response.
