Definition
A red herring is a rhetorical device, logical fallacy, or literary technique that involves diverting attention away from the relevant issue or argument by introducing an irrelevant or misleading point. The purpose of a red herring is to distract or mislead an audience, thereby obscuring the original topic under consideration.
Etymology
The expression derives from the practice of using strongly scented smoked herring (a “red herring”) to train hunting dogs or to throw them off a scent trail. The figurative use of the term to denote a false trail in argument or investigation dates to the early 19th century. The earliest recorded figurative usage appears in a 1807 article by English essayist William Cobbett, who wrote that “a red herring” could be used “to divert the attention of the public.”
Logical and Rhetorical Context
In formal logic, a red herring is classified as an informal fallacy because the argument’s premises, while potentially true, do not support the conclusion. It is distinct from a straw man (misrepresenting an opponent’s position) and from ad hominem attacks (targeting the person rather than the argument). Red herrings often appear in debate, political discourse, advertising, and media commentary when a speaker seeks to shift focus away from a controversial or uncomfortable subject.
Literary and Narrative Use
In fiction, particularly in mystery and detective genres, a red herring is a plot element that misleads readers or characters, creating suspense and complicating the resolution of the central mystery. Classic examples include false clues planted by authors such as Arthur Conan Doyle and Agatha Christie. The technique relies on the audience’s expectation that every clue is pertinent; a red herring intentionally violates that expectation.
Examples
- Political debate: During a discussion of healthcare policy, a candidate shifts to criticize the opponent’s personal tax history, thereby avoiding the substantive policy question.
- Legal argument: A defense attorney raises the defendant’s charitable activities to suggest good character, diverting attention from forensic evidence linking the defendant to the crime scene.
- Mystery fiction: A novel presents a suspicious character who appears to have motive and opportunity, only to reveal that the true perpetrator is unrelated to that character.
Detecting Red Herrings
Analysts look for the following indicators:
- The introduced point does not logically influence the original claim.
- The diversion is timely, appearing at a juncture where the original issue is unfavorable to the speaker.
- The irrelevant point is emotionally charged or sensational, increasing its persuasive effect.
Academic Treatment
Scholars in informal logic and argumentation theory discuss red herrings under the broader category of irrelevant evidence or distraction fallacies. Standard texts such as A Concise Introduction to Logic (Hurley, 2021) list the red herring among common fallacies taught in introductory philosophy courses.
Cultural Impact
The term “red herring” has entered common parlance, often used colloquially to accuse a speaker of intentionally misleading or sidestepping an issue. It appears in journalistic style guides as a warning against presenting misleading information that can confuse public discourse.
