Differential association
Differential association theory is a foundational criminological framework developed by sociologist Edwin H. Sutherland, positing that criminal behavior is learned through intimate social interactions in which individuals acquire both the techniques of committing crime and the rationalizations or attitudes that define such acts as acceptable or favorable compared to lawful conduct.[1] First articulated in the third edition of Sutherland's Principles of Criminology in 1939, the theory rejects individualistic explanations like biological determinism or psychological pathology in favor of a process where the balance of learned "definitions" favorable to law violation—gleaned from the frequency, duration, priority, and intensity of associations—determines deviant outcomes.[1] The theory comprises nine propositions outlining its mechanisms: criminal behavior is learned via communication in intimate groups; it involves mastering specific techniques and assimilating motives or drives indistinguishable from those in non-criminal acts; a preponderance of pro-violation definitions over anti-violation ones tips toward delinquency; such learning occurs through excess of favorable definitions rather than mere imitation; and associations differ in their influence based on contextual factors like timing and emotional intensity.[2] This social learning model marked a paradigm shift in criminology, elevating sociological explanations of crime as a group-derived "way of life" and influencing subsequent theories, including Akers' social learning theory, while extending applicability to white-collar offenses beyond street crime.[1][3] Empirically, the theory has garnered partial support through studies linking peer associations to delinquency rates, such as those demonstrating higher offending among youth with delinquent friends, yet faces challenges in measurement—relying often on self-reports prone to bias—and in explaining why not all in criminal milieus offend or the origins of initial criminal groups, prompting critiques of its completeness as a general theory.[3][4] Despite these limitations, its emphasis on proximate social processes remains a cornerstone, underscoring causal pathways rooted in observable interactions over remote or untestable factors.[1]Origins and Historical Context
Edwin Sutherland's Formulation
Edwin H. Sutherland, an American sociologist and pioneering criminologist (1883–1950), first articulated the differential association theory in the third edition of his seminal textbook Principles of Criminology, published in 1939.[2][5] In this edition, Sutherland posited that criminal behavior arises not from innate traits or isolated psychological factors, but through a process of social learning wherein individuals acquire attitudes and techniques conducive to law violation via intimate interactions with others.[6] He emphasized that the key mechanism is the "differential" balance of associations: exposure to more communication containing definitions favorable to violating laws than unfavorable ones tips the scale toward delinquency, with learning occurring in direct proportion to the intensity and duration of such contacts.[7] This formulation explicitly rejected biological determinism and individualistic explanations prevalent in earlier criminological thought, grounding crime instead in cultural transmission within social groups.[8] Sutherland refined and expanded the theory in the fourth edition of Principles of Criminology in 1947, providing a more systematic outline through nine propositions that specified the learning process, the content of learned behaviors (including rationalizations and specific techniques of crime commission), and the conditions under which associations become criminogenic.[5][7] Central to this version was the assertion that "a person becomes delinquent because of an excess of definitions favorable to violation of law over definitions unfavorable to violation of law," with criminality treated as a probabilistic outcome of associative imbalances rather than a deterministic trait.[6] Sutherland drew on empirical observations from his studies of professional thieves and white-collar offenders to illustrate how such learning operates across diverse criminal domains, underscoring the theory's applicability beyond lower-class street crime.[9] This 1947 iteration solidified differential association as a foundational social learning paradigm in criminology, influencing subsequent theories by shifting focus from pathology to relational dynamics in behavior acquisition.[2]Precursors and Intellectual Influences
Edwin Sutherland's differential association theory emerged from a synthesis of early 20th-century sociological thought, particularly rejecting biological and individualistic explanations of crime in favor of cultural and interactive processes. Sutherland, who studied at the University of Chicago from 1906 to 1913, was exposed to the Chicago School's emphasis on social ecology and disorganization, including the works of Robert E. Park and Ernest Burgess, which highlighted how urban environments foster deviant patterns through cultural transmission rather than inherent traits.[10] This foundation informed Sutherland's view that criminal behavior arises from situational learning within communities, as evidenced by empirical studies on delinquency areas by Clifford R. Shaw and Henry D. McKay in the 1930s.[10][7] A key precursor was French sociologist Gabriel Tarde's laws of imitation (1890), which posited that individuals acquire behaviors, including criminal ones, through imitating those around them, especially in intimate groups.[9] Sutherland refined this into a sociological framework, expanding beyond mere imitation to differential exposure to pro- and anti-criminal definitions, as noted in the 1947 edition of his Principles of Criminology where Proposition 8 incorporates broader learning mechanisms.[10] Tarde's emphasis on social environment over innate factors aligned with Sutherland's critique of Lombrosian biological determinism, though Sutherland emphasized ratios of associations rather than unidirectional imitation.[11] Symbolic interactionism profoundly shaped the theory's interactive core, drawing from George Herbert Mead's social psychology, which Sutherland encountered during his Chicago years. Mead's concepts of role-taking and the self as emerging from social interactions influenced Sutherland's idea that criminal definitions are internalized through communication, as reflected in Proposition 2 of the 1947 formulation.[10] Similarly, Charles Horton Cooley's primary group dynamics and looking-glass self provided the basis for understanding intimate associations' role in behavior formation; Sutherland credited Cooley in 1927 as influencing him more than any other writer.[10] Thorsten Sellin's culture conflict theory (1938) further contributed, positing that clashes between normative systems—such as immigrant versus host cultures—generate deviance, a concept Sutherland integrated into his sixth proposition on the content of learned definitions.[7][10] Collaborations with Sellin, including on prison reform in 1931, helped formalize differential association in 1939.[10] W.I. Thomas's situational approach and empirical focus on attitudes also informed Sutherland's rejection of multiple-factor causation, advocating unified cultural explanations.[10] These influences culminated in Sutherland's iterative development, detailed in his 1942 personal account of "borrowing from and stimulation by colleagues," leading to the theory's emphasis on learned, socially transmitted criminality.[10]Core Theoretical Principles
The Nine Propositions
The nine propositions of differential association theory, as formulated by Edwin H. Sutherland in the fourth edition of Principles of Criminology (1947), provide a systematic outline of how criminal behavior is acquired through social interactions. These statements reject innate or biological explanations for crime, instead positing it as a learned response shaped by the balance of pro- and anti-criminal influences in one's associations.[12][2]- Criminal behavior is learned. This proposition asserts that individuals are not born predisposed to crime but develop such tendencies through exposure and socialization, countering earlier theories attributing deviance to inherent traits or pathologies.[12][2]
- Criminal behavior is learned in interaction with other persons in a process of communication. Learning occurs via verbal and non-verbal exchanges, encompassing both face-to-face encounters and indirect influences like media, though Sutherland emphasized personal interactions as primary.[12][2]
- The principal part of the learning of criminal behavior occurs within intimate personal groups. Sutherland highlighted that close relationships—such as family, peers, or gangs—exert the strongest influence, as these groups provide repeated, emotionally charged exposure to criminal norms over distant or superficial associations.[12][2]
- When criminal behavior is learned, the learning includes (a) techniques of committing the crime, which are sometimes very complicated, sometimes very simple, and (b) the specific direction of motives, drives, rationalizations, and attitudes. This distinguishes between practical skills (e.g., lock-picking or fraud schemes) and attitudinal shifts, where offenders adopt justifications like denying harm to victims to neutralize guilt.[12][2]
- The specific direction of motives and drives is learned from definitions of the legal code as favorable or unfavorable. Individuals internalize views of laws as either supportive of compliance (e.g., laws as protective) or amenable to violation (e.g., laws as unjust or irrelevant), shaping whether legal prohibitions are respected or dismissed.[12][2]
- A person becomes delinquent because of an excess of definitions favorable to violation of law over definitions unfavorable to violation of law. The theory's ratio hypothesis posits delinquency arises when pro-criminal attitudes outweigh anti-criminal ones, with no fixed threshold specified but an imbalance as the causal tipping point.[12][2]
- Differential associations may vary in frequency, duration, priority, and intensity. The quality of associations matters: frequent, long-lasting, early-formed, or emotionally intense contacts amplify their impact, explaining why sporadic exposure to crime may not lead to adoption while sustained immersion does.[12][2]
- The process of learning criminal behavior by association with criminal and anticriminal patterns involves all of the mechanisms that are involved in any other learning. Sutherland aligned the theory with general psychological learning processes, such as imitation, reinforcement, and conditioning, without invoking unique mechanisms for crime.[12][2]
- While criminal behavior is an expression of general needs and values, it is not explained by those general needs and values, since non-criminal behavior is an expression of the same needs and values. Universal drives like economic gain or status-seeking do not differentiate criminals from non-criminals; instead, the direction of these drives—toward lawful or unlawful channels—is determined by learned definitions.[12][2]
