Signs of disorder in a neighborhood can lead to other broken social
norms

The mere presence of graffiti doubles the number of people littering and
stealing in a neighborhood, new research suggests.
The results, which are detailed in the Nov. 21 issue of the journal
Science, support and expand on the so-called broken windows theory, which
forms the backbone of many crime prevention programs in major cities such
as New York.
The theory sugge
sts that signs of disorder, such as broken windows,
graffiti and litter, can open the door to individuals breaking other
social norms and rules. In New York's "Quality of Life
Campaign," adopted in the mid-1990s, city filth, including graffiti,
street
litter and signs of vandalism, were removed. And petty
crime rates did drop.
Even still, solid research backing the theory had been lacking. Studies
conducted to date have not proven if the graffiti-type behaviors caused
more rule-breaking or whether another variable caused both behaviors, the
study researchers say.
With funding from the University of Groningen, Netherlands, the
university's Kees Keizer and his colleagues set up six field experiments.
In one, the researchers placed a standard prohibition sign with the text
"Graffiti" in the middle of a red circle on an alley wall where
people typically parked their bikes. The wall was painted one color.
The researchers also attached fliers with elastic bands to
bike
handlebars. The flier had to be removed for easy use of handlebars.
After the bikes were removed, researchers counted littered fliers as
those on the ground or hanging on another bicycle. There were no
trashcans around.

In that same setting, on another occasion, the researchers applied
graffiti to the alley wall where the anti-graffiti sign was attached.
They found that out of the nearly 80 bicyclists monitored, 69 percent
littered in the graffiti scenario compared with just 33 percent in the
non-graffiti alley.
In another experiment, the researchers showed that bikes illegally locked
to a fence caused more people to violate a no-trespassing sign in the
area.
In two other experiments, the researchers found that graffiti and litter
can lead to stealing. They stuck an envelope that contained cash partway
into a mailbox so that passersby could see the envelope and the money
within. In one scenario, graffiti covered the mailbox. And 25 percent of
passersby stole the envelope from the graffiti-covered mailbox, while
just 13 percent stole from the clean mailbox.
When litter was scattered around the clean mailbox, nearly 30 percent of
passersby stole the envelope, compared with the 13 percent in the
litter-free and graffiti-free scenario.
Laws that prohibit littering or graffiti, say with a fine, won't work by
themselves, study team member Keizer said. "You need to make that
link between the sanction and the norm," he told LiveScience.
"Otherwise people will just get focused on avoiding that
sanction."
He added, "And when the police officer isn't around anymore you see
the norm-violating behavior become apparent again."
In addition, people need to
feel part of a community, he said, so that potential rule-breakers
will care about how their crimes affect others in the community.
