Seeing an image like the one above can unleash the lurking delinquent from within. One may feel compelled to throw a rock at the window just to relish in the sound of the shattering glass. Small instances of disorder do in fact encourage a crescendo of greater disorder. I was quite surprised when this seemingly self-evident theory was disputed in class.
The above article published in the economist in 2008, describes research conducted by social scientists in the Netherlands who set out to find if signs of vandalism, litter, and low-level lawbreaking could affect people's behavior and make them more inclined to commit crime. One experiment found that people were much more likely to litter when they were in an alley that had graffiti on the walls, where graffiti was explicitly banned, versus when the alley was freshly painted. Another experiment found that people were much more likely to trespass in disobedience of a sign when they were in the presence of bicycles which were locked to a fence, which was explicitly banned by another sign. The most remarkable study found that people were more likely to steal money from an envelope that was protruding from a mailbox when there was graffiti on the mailbox or when there was litter on the ground. None of these results should really be that surprising.
People tend to comply with the social-norms in which they find themselves. When order is the norm, people will tend to follow suit because they are afraid of being the one who stands out. When disorder is the norm, people are much more inclined to behave in selfish ways that defy the public good. In the microcosm of a school, these affects are all the more accentuated. To create an environment suitable for learning, schools need to manage the smallest cases of disorder, or things can get out of control very quickly. Part of setting high standards is having high expectations for good behavior.
The problem with Kelling's article lies not with his statement of the problem, but with his suggestion that increased policing is the solution. Similarly, the problem with zero-tolerance policies is that they attempt to solve the problem through excluding students who exhibit troubling behavior. Pushing the problem under the carpet does not make it go away. Every student that fails to attain an adequate education poses a problem for society, so suspending and expelling children from school cannot be a good policy. We must instead find positive ways to encourage good behavior and give students having problems the support and counseling that they need. A school that manages to create an environment of strong respect and personal accountability can avoid the graffiti on the walls, the cursing at teachers, the skipping of class and many of the other signs of a disordered school that lead to far greater problems.
