"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."
