[1] The theory suggests that policing methods that target minor crimes, such as vandalism, loitering, public drinking and fare evasion, help to create an atmosphere of order and lawfulness.
A 1996 criminology and urban sociology book, Fixing Broken Windows: Restoring Order and Reducing Crime in Our Communities by George L. Kelling and Catharine Coles, is based on the article but develops the argument in greater detail.
Conversely, a disordered environment, one that is not maintained (broken windows, graffiti, excessive litter), sends the signal that the area is not monitored and that criminal behavior has little risk of detection.
Wilson and Kelling found that studies done by psychologists suggest people often refuse to go to the aid of someone seeking help, not due to a lack of concern or selfishness "but the absence of some plausible grounds for feeling that one must personally accept responsibility".
[1] On the other hand, others plainly refuse to put themselves in harm's way, depending on how grave they perceive the nuisance to be; a 2004 study observed that "most research on disorder is based on individual level perceptions decoupled from a systematic concern with the disorder-generating environment.
[17] In an earlier publication of The Atlantic released March 1982, Wilson wrote an article indicating that police efforts had gradually shifted from maintaining order to fighting crime.
[19] Ranasinghe includes that Jacobs' approach toward social disorganization was centralized on the "streets and their sidewalks, the main public places of a city" and that they "are its most vital organs, because they provide the principal visual scenes".
One of Kelling's adherents, David L. Gunn, implemented policies and procedures based on the Broken Windows Theory, during his tenure as President of the New York City Transit Authority.
[24] Later, in 2016, Brian Jordan Jefferson used the precedent of Kelling and Sousa's study to conduct fieldwork in the 70th precinct of New York City, which it was corroborated that crime mitigation in the area were concerning "quality of life" issues, which included noise complaints and loitering.
In half of the spots, authorities cleared trash, fixed streetlights, enforced building codes, discouraged loiterers, made more misdemeanor arrests, and expanded mental health services and aid for the homeless.
"[33][34] An 18-month study by Carlos Vilalta in Mexico City showed that framework of Broken Windows Theory on homicide in suburban neighborhoods was not a direct correlation, but a "concentrated disadvantage" in the perception of fear and modes of crime prevention.
Other side effects of better monitoring and cleaned up streets may well be desired by governments or housing agencies and the population of a neighborhood: broken windows can count as an indicator of low real estate value and may deter investors.
Fixing broken windows and attending to the physical appearance of a school cannot alone guarantee productive teaching and learning, but ignoring them likely greatly increases the chances of a troubling downward spiral.
David Thacher, assistant professor of public policy and urban planning at the University of Michigan, stated in a 2004 paper:[40] [S]ocial science has not been kind to the broken windows theory.
[16] The policy targeted people in areas with a significant amount of physical disorder and there appeared to be a causal relationship between the adoption of broken windows policing and the decrease in crime rate.
Sridhar, however, discusses other trends (such as New York City's economic boom in the late 1990s) that created a "perfect storm" that contributed to the decrease of crime rate much more significantly than the application of the broken windows policy.
In a 2007 study called "Reefer Madness" in the journal Criminology and Public Policy, Harcourt and Ludwig found further evidence confirming that mean reversion fully explained the changes in crime rates in the different precincts in New York in the 1990s.
His data supports a materialist view: changes in physical decay, superficial social disorder, and racial composition do not lead to higher crime, but economic decline does.
He contends that the example shows that real, long-term reductions in crime require that urban politicians, businesses, and community leaders work together to improve the economic fortunes of residents in high-crime areas.
They argue that a third factor, collective efficacy, "defined as cohesion among residents combined with shared expectations for the social control of public space," is the cause of varying crime rates observed in an altered neighborhood environment.
[49] In the winter 2006 edition of the University of Chicago Law Review, Bernard Harcourt and Jens Ludwig looked at the later Department of Housing and Urban Development program that rehoused inner-city project tenants in New York into more-orderly neighborhoods.
In Dorothy Roberts's article, "Foreword: Race, Vagueness, and the Social Meaning of Order Maintenance and Policing", she says that the broken windows theory in practice leads to the criminalization of communities of color, who are typically disfranchised.
[53] She underscores the dangers of vaguely written ordinances that allow for law enforcers to determine who engages in disorderly acts, which, in turn, produces a racially skewed outcome in crime statistics.
[54] Similarly, Gary Stewart wrote, "The central drawback of the approaches advanced by Wilson, Kelling, and Kennedy rests in their shared blindness to the potentially harmful impact of broad police discretion on minority communities.
Specifically, Bench Ansfield has shown that in their 1982 article, Wilson and Kelling cited only one source to prove their central contention that disorder leads to crime: the Philip Zimbardo vandalism study (see Precursor Experiments above).
[58] He further states that research conducted on implicit bias and stereotyping of cultures suggests that community members hold unrelenting beliefs of African Americans and other disadvantaged minority groups, associating them with crime, violence, disorder, welfare, and undesirability as neighbors.
[53] According to Bruce D. Johnson, Andrew Golub, and James McCabe, applying the broken windows theory in policing and policymaking can result in development projects that decrease physical disorder but promote undesired gentrification.
In the 2005 book Freakonomics, coauthors Steven D. Levitt and Stephen J. Dubner confirm and question the notion that the broken windows theory was responsible for New York's drop in crime, saying "the pool of potential criminals had dramatically shrunk".
Levitt had in the Quarterly Journal of Economics attributed that possibility to the legalization of abortion with Roe v. Wade, which correlated with a decrease, one generation later, in the number of delinquents in the population at large.
[62] In his 2012 book Uncontrolled: The Surprising Payoff of Trial-and-Error for Business, Politics, and Society, Jim Manzi writes that of the randomized field trials conducted in criminology, only nuisance abatement per broken windows theory has been successfully replicated.
