Broken Window Theory
The Broken Window Theory is a criminological theory of the norm-setting and singling effect of urban disorder and vandalism on additional crime and anti-social behaviour.
The theory further proposes that the prevalence of disorder creates fear in the minds of citizens who are convinced that the area is unsafe. This withdrawal from the community weakens social controls that previously kept criminals in check. Once this process begins, it feeds itself. Disorder causes crime, and crime causes further disorder and crime.
“Consider a building with a few broken windows. If the windows are not repaired, the tendencies for vandals to break a few more windows. Eventually, they may even break into the building, and if it’s unoccupied, perhaps become squatters or light fires inside.”
