A smear campaign, also referred to as a smear tactic or simply a smear, is an effort to damage or call into question someone's reputation, by propounding negative propaganda. It makes use of discrediting tactics.
It can be applied to individuals or groups. Common targets are public officials, politicians, political candidates, activists, and ex-spouses. The term also applies in other contexts, such as the workplace.
The term smear campaign became popular around 1936.
A smear campaign is an intentional, premeditated effort to undermine an individual's or group's reputation, credibility, and character. Like negative campaigning, most often smear campaigns target government officials, politicians, political candidates, and other public figures. However, private persons or groups may also become targets of smear campaigns perpetrated in companies, institutions, the legal system, and other formal groups. Discrediting tactics are used to discourage people from believing in the figure or supporting their cause, such as the use of damaging quotations.
Smear tactics differ from normal discourse or debate in that they do not bear upon the issues or arguments in question. A smear is a simple attempt to malign a group or an individual with the aim of undermining their credibility.
Smears often consist of ad hominem attacks in the form of unverifiable rumors and distortions, half-truths, or even outright lies; smear campaigns are often propagated by gossip magazines. Even when the facts behind a smear campaign are demonstrated to lack proper foundation, the tactic is often effective because the target's reputation is tarnished before the truth is known.
Smear campaigns can also be used as a campaign tactic associated with tabloid journalism, which is a type of journalism that presents little well-researched news and instead uses eye-catching headlines, scandal-mongering and sensationalism. For example, during Gary Hart's 1988 presidential campaign (see below), the New York Post reported on its front page big, black block letters: "GARY: I'M NO WOMANIZER.
