Left Realism, Right Realism, and Broken Windows Theory

Realist criminology takes its name from a deliberate contrast with what its founders called idealism. By the late 1970s, British criminology had split along a line that ran roughly with party politics.

On one side, radical and critical criminologists, drawing on labelling theory and Marxist analysis, argued that crime was largely a construction of state power, that official crime statistics reflected policing choices rather than real harm, and that the working class offender was often better understood as resisting an unequal system than as a threat to it.

On the other side, conservative criminologists treated rising crime rates as evidence of moral decline and argued for tougher deterrence and stricter policing, largely ignoring the social conditions in which crime occurred.

Jock Young, who had himself been a leading figure in the radical criminology of the 1970s, broke with that tradition in the early 1980s. Working with John Lea, he argued in the 1984 book What Is to Be Done About Law and Order? that the left's earlier position amounted to left idealism: it minimised working class victimisation, dismissed rising crime rates as a myth, and left crime policy to the right by default.

Local crime surveys carried out in London during this period, including surveys in Islington, showed that fear of crime and actual victimisation fell heavily on poor, working class and minority communities, the very people left criminology claimed to speak for.

At almost the same moment, a parallel realism was forming on the right. Its central figures were less interested in structural causes and more interested in what made an individual decide to offend at a given moment. James Q. Wilson had already argued, in his 1975 book Thinking About Crime, that criminology spent too much energy on root causes that policy could not quickly change and too little on the immediate situational factors that could be altered.

What the two realisms shared was impatience with theory that offered no near-term lever on crime. What separated them was where they located the lever: left realism kept the state, the economy and inequality in the frame alongside the offender, while right realism narrowed the frame to the offender's choices and the immediate environment that shaped them.

Left realism's central analytic tool is the square of crime, a model that insists any crime event has to be explained by looking at four elements together rather than any one in isolation: the offender, the victim, the state, meaning formal agencies such as the police and courts, and the public, meaning informal social control exercised by communities themselves.

Young argued that earlier criminologies each fixed on one corner of the square and ignored the rest. Positivist criminology studied the offender alone. Victimology, taken in isolation, studied the victim alone. Radical criminology studied the state's power to define crime and largely ignored victims. Left realism's claim was that crime rates, fear of crime and the effectiveness of any intervention could only be understood by tracing the relationships between all four corners at once.

This framework produced a distinctive research method, the local crime survey. Rather than relying only on police-recorded crime, left realist researchers went into specific neighbourhoods and asked residents directly what crime and disorder they experienced, how safe they felt, and how they rated the police.

The surveys consistently found that crime was not evenly spread, that it concentrated on those least able to absorb its costs, and that dissatisfaction with policing was itself a driver of further disorder because communities stopped cooperating with officers they distrusted.

Left realism's policy programme followed from this diagnosis. Because the square of crime treats the state and the public as part of the explanation, its recommended interventions are multi-agency: better and more accountable policing, social and economic investment in high-crime neighbourhoods, and community-based crime prevention that restores informal social control rather than replacing it with more enforcement alone.

This is one reason left realism sits closer to structural theories than right realism does, even though it shares the realist insistence on taking crime rates seriously rather than treating them as fabricated.

Critics on the left argued Young had conceded too much ground to conservative crime control, since taking official victimisation data seriously risked legitimising more policing. Critics on the right argued left realism still under-weighted individual responsibility. Young's response was that a criminology has failed its subject if it cannot say anything useful to the people who are actually burgled, assaulted or made afraid to leave their homes at night.

Right realism starts from a different premise: crime is best explained as the outcome of choices made by individuals who weigh the rewards of an act against its likely costs, given their own temperament and the immediate opportunity in front of them.

The fullest statement of this position is Crime and Human Nature, published in 1985 by James Q. Wilson and the psychologist Richard Herrnstein. They argued that some individuals are more prone to crime than others because of a mix of constitutional traits, such as low impulse control, and upbringing, particularly inconsistent discipline in childhood, and that these predispositions interact with immediate situational rewards to produce a decision to offend.

This account deliberately narrows the causal story compared with sociological criminology. Wilson and Herrnstein were not denying that poverty, family breakdown or neighbourhood decline correlate with crime, but they argued these factors work mainly by weakening the informal controls, especially consistent parenting and community supervision, that would otherwise restrain a predisposed individual. The policy implication was to strengthen deterrence and informal supervision in the near term rather than wait for slower structural fixes to poverty or inequality.

Right realism has an obvious affinity with rational choice and routine activity theories, which similarly treat the offender as a reasoning actor responding to opportunity, guardianship and risk.

All three currents shifted American and British crime policy toward situational measures: target hardening, visible surveillance, and policing that increases the certainty of an immediate response rather than relying on the eventual severity of a court sentence. This family of theories underwrote a broader turn toward what criminologists call administrative or actuarial criminology, concerned less with why an individual becomes a criminal and more with managing the aggregate risk that offending presents in a given place.

The theory's critics argue it downplays the extent to which choice is itself shaped by structural disadvantage, and that treating self-control as a fixed early-life trait risks writing off whole populations as permanently high risk. Wilson's defenders replied that a theory does not need to explain everything about crime's distant causes to be useful; it only needs to identify a lever that can change behaviour now, and individual deterrence and situational control were, in their view, that lever.

Broken windows theory is right realism's most influential single idea. James Q. Wilson and George Kelling set it out in an article called "Broken Windows: The Police and Neighborhood Safety", published in The Atlantic Monthly in March 1982. The article opens with a simple image: a building with one broken window that is left unrepaired will soon have every window broken, because the unrepaired window signals that no one cares and no one is watching.

Wilson and Kelling extended the image from buildings to neighbourhoods. Visible signs of disorder, whether physical, such as graffiti, litter and abandoned cars, or social, such as public drinking, aggressive begging or unchecked rowdiness, communicate to residents and potential offenders alike that a place has lost effective informal control.

Law-abiding residents respond to that signal by withdrawing: they use public space less, supervise the street less, and in the most severe cases move away if they can. That withdrawal removes exactly the informal surveillance and social cohesion that would otherwise deter more serious offenders, so petty disorder becomes a permission structure for burglary, robbery and violence, not because disorder and serious crime share a cause but because disorder erodes the community mechanisms that keep serious crime in check.

The theory's policy conclusion followed directly: police should treat minor disorder as worth intervening on in its own right, not merely as a nuisance beneath their attention, because doing so protects the informal controls that prevent escalation. This inverted the priorities of much conventional policing, which had focused resources on responding to serious crimes already committed rather than on the disorder that, on Wilson and Kelling's account, preceded them.

It is worth being precise about what the 1982 article actually claimed and did not claim. Wilson and Kelling did not argue that disorder and serious crime were the same thing, and they did not present broken windows as a fully tested causal model; they presented it as a plausible mechanism drawn substantially from earlier foot-patrol research in Newark, New Jersey, and they explicitly framed it as a hypothesis for police departments to test in practice. That caveat was frequently lost as the theory moved from an academic article into department policy.

Broken windows theory reached its most consequential test in New York City in the 1990s. William Bratton, appointed head of the New York City Transit Police in 1990 and later Police Commissioner under Mayor Rudolph Giuliani from 1994, made order maintenance an explicit department strategy, directing officers to enforce consistently against fare evasion, public drinking, aggressive panhandling and other visible disorder, alongside the CompStat system of weekly crime-mapping and precinct accountability. Proponents pointed to the sharp fall in New York's violent crime rate over the following years as vindication of the broken windows mechanism.

That claim has been heavily disputed, and the dispute has produced some of the most cited empirical work in criminology. New York's crime decline coincided with a national fall in crime across almost every large American city during the 1990s, including cities that adopted no comparable order maintenance strategy, which makes it hard to attribute New York's specific drop to broken windows policing alone rather than to shared national factors such as the waning of the 1980s crack cocaine markets, a strong economy, an aging population, and rising incarceration.

Robert Sampson and Stephen Raudenbush's 1999 study of Chicago neighbourhoods used trained observers to rate disorder block by block rather than relying on residents' perceptions, and found that disorder's apparent link to crime weakened to statistical insignificance once collective efficacy, meaning neighbours' willingness to intervene and trust each other, was controlled for.

Their conclusion was that collective efficacy, not disorder itself, was doing the causal work broken windows theory attributed to broken windows. Bernard Harcourt and Jens Ludwig's 2006 reanalysis of the New York precinct data and a separate five-city social experiment likewise found no reliable relationship between falling disorder and falling crime once regression to the mean was accounted for.

Working the other side of the argument, George Kelling and William Sousa's 2001 study of New York precincts reported a strong association between misdemeanour arrests and reduced violent crime even after controlling for other factors, and defenders of the theory argue the Chicago and New York settings differ enough that neither reanalysis settles the question for every city.

Order maintenance policing also drew a sustained fairness critique, since concentrating stops and arrests on visible low-level disorder falls unevenly on the neighbourhoods where that disorder is most visible and most heavily policed.

New York's stop and frisk numbers rose alongside order maintenance policing over the same years, and courts later found the practice's racially disproportionate application unconstitutional. The legitimacy costs of high-volume, low-discretion stops, and how procedural justice research explains them, belong to policing styles and legitimacy and are not repeated here.

The wider lesson many criminologists draw is a caution about the gap between a plausible mechanism and a proven one. Broken windows theory offered a clear, testable causal story, which is precisely why it could be adopted so quickly by police departments beyond New York, in cities across the United States and in police forces in England and Wales, but the underlying claim that repairing disorder reliably reduces serious crime remains more contested than its early public reception suggested.

Left realism and right realism responded to the same problem, rising and increasingly feared crime in the late twentieth century, but they diverge on almost every point that follows from that shared starting point.

Right realism narrows the causal frame to the offender and the immediate situation, treats self-control and deterrence as the operative levers, and produced broken windows theory and order maintenance policing as its clearest policy legacy. Left realism keeps a wider frame, the square of crime's offender, victim, state and public, treats inequality and policing legitimacy as part of the explanation rather than as noise to be set aside, and produces multi-agency prevention and accountable policing as its policy legacy.

Left realism did not stop developing after its 1980s foundational texts. Its local crime survey method has been used repeatedly since to document victimisation that official statistics undercount, particularly domestic violence, racially motivated harassment and crime against women, because household surveys reach victims who never report to police.

Its multi-agency model, bringing together police, local government, schools and social services around a shared crime prevention plan for a specific area, influenced the partnership approach to crime reduction later written into policy in England and Wales and echoed in comparable local partnership schemes elsewhere.

The two schools also differ in how falsifiable their central claims are. Right realism's individual-choice model and broken windows theory generate specific, testable predictions, which is why decades of empirical policing research have been able to interrogate them directly, sometimes supporting and sometimes undermining the broken windows mechanism.

Left realism's square of crime is harder to test as a single causal claim because it is explicitly a framework for holding four elements in view together rather than a single mechanism, though its empirical arm, the local crime survey, has produced a large and durable body of victimisation evidence.

Taken together, the two realisms mark the point at which criminology, across both the political left and the political right, turned toward policy that could change outcomes in the near term rather than waiting on distant social transformation. That shift has shaped policing strategy in the United States, the United Kingdom and, through the international circulation of both zero tolerance policing and multi-agency crime prevention, in police reform debates well beyond either country.
