Zero-tolerance


A zero tolerance policy is one which imposes strict punishment for infractions of a stated rule, with the intention of eliminating undesirable conduct. Zero-tolerance policies forbid persons in positions of authority from exercising discretion or changing punishments to fit the circumstances subjectively; they are required to impose a pre-determined punishment regardless of individual culpability, extenuating circumstances, or history. This pre-determined punishment, whether mild or severe, is always meted out.

Zero-tolerance policies are studied in criminology and are common in formal and informal policing systems around the world. The policies also appear in informal situations where there may be sexual harassment or Internet misuse in educational and workplace environments. In 2014, the mass incarceration in the United States based upon minor offenses has resulted in an outcry on the use of zero tolerance in schools and communities.

Little evidence supports the claimed effectiveness of zero-tolerance policies. One underlying problem is that there are a great many reasons why people hesitate to intervene, or to report behavior they find to be unacceptable or unlawful. Zero-tolerance policies address, at best, only a few of these reasons.

According to the Online Etymology Dictionary, the first recorded use of the term "zero tolerance" was in 1972. It was originally used in political language in the United States.

An earlier use of the term came in the mid-1960s, in reference to an absolute ban of the pesticide heptachlor by the United States Food and Drug Administration; for example, in an article that appeared in the June 1963 issue of Popular Mechanics, it is stated that "Heptachlor, though, is even more toxic and has been given a 'zero tolerance' by the FDA; that is, not even the slightest trace of heptachlor is permitted on food."

The idea behind zero-tolerance policies can be traced back to the Safe and Clean Neighborhoods Act, approved in New Jersey in 1973, which has the same underlying assumptions. The ideas behind the 1973 New Jersey policy were later popularized in 1982, when a US cultural magazine, The Atlantic Monthly, published an article by James Q. Wilson and George L. Kelling about the broken windows theory of crime. Their name for the idea comes from the following example:
