A recent series of experiments in the Netherlands has shown some dramatic evidence in favor of the so-called broken windows theory. This theory predicts that neighborhood social and physical incivilities will incite people to engage in criminal behaviors. Examples of incivilities include litter, graffiti, loitering, and public intoxication. One experiment gave passers by the opportunity to steal a €5 note from an open mailbox. The portion of people who decided to pocket the money doubled when the area was littered with trash or covered in graffiti. The results of this study are compelling evidence that city governments should respond to signs of physical disorder early.
