Maybe the years I spent playing the piano in taverns in Chicago and elsewhere led me to believe that the people who did that mundane work were as imp… - Howard S. Becker

Even though no one else discovers the nonconformity or enforces the rules against it, the individual who has committed the impropriety may himself act as the enforcer. He may brand himself as deviant because of what he has done and punish himself in one way or another for his behavior.

The prototype of the rule creator, but not the only variety as we shall see, is the crusading reformer. He is interested in the content of rules. The existing rules do not satisfy him because there is some evil which profoundly disturbs him. He feels that nothing can be right in the world until rules are made to correct it. He operates with an absolute ethic; what he sees is truly and totally evil with no qualification. Any means is justified to do away with it. The crusader is fervent and righteous, often self-righteous.

Treating a person as though he were generally rather than specifically deviant produces a self-fulfilling prophecy. It sets in motion several mechanisms which conspire to shape the person in the image people have of him. It the first place, one tends to be cut off, after being identified as deviant, from participation in more conventional groups, even though the specific consequences of the particular deviant activity might never of themselves have caused the isolation had there not also been the public knowledge and reaction to it. For example, being a homosexual may not affect one’s ability to do office work, but to be known as a homosexual in an office may make it impossible to continue working there. Similarly, though the effects of opiate drugs may not impair one’s working ability, to be known as an addict will probably lead to losing one’s job... The homosexual who is deprived of a “respectable” job by the discovery of his deviance may drift into unconventional, marginal occupations where it does not make so much difference. The drug addict finds himself forced into other illegitimate kinds of activity, such as robbery and theft, by the refusal of respectable employers to have him around.
