Red herring
A red herring is an informal fallacy in which irrelevant information is introduced to divert attention away from the actual question being argued.
The step most authors miss
Doing CRediT right? Don’t stop at the statement.
A CRediT statement credits you inside one paper. The recognition CRediT was built for happens when those roles are tied to you, persistently. Sign in with your ORCID — free — and claim your CRediT contributions on casrai.org, the home of the standard. They become a verified, portable part of your identity, not a line that disappears into one PDF.
Free: claim your contributions, then export a journal-ready CRediT statement, schema.org structured data, JATS XML, CSV or BibTeX — and preview your public profile. A membership publishes that profile publicly and verifies the journals you serve.
How the diversion works
A red herring succeeds by exploiting the fact that the introduced topic is often interesting, emotive or superficially connected to the real issue. Instead of answering the question on the table, the arguer pivots to something else and hopes the audience follows. Because the new topic does not actually bear on the original claim, any "conclusion" reached about it leaves the real question untouched. Logicians group the red herring with other fallacies of relevance, since its defining flaw is that the material offered is simply beside the point.
Red herring versus straw man
A red herring and a straw man are both diversionary, but they differ in method. A straw man misrepresents the opponent’s actual argument and then attacks the distorted version. A red herring does not necessarily distort anything — it simply changes the subject to something irrelevant. Put differently, a straw man attacks a fake version of the point, whereas a red herring walks away from the point altogether. Many red herrings also work by smuggling in an appeal to emotion that feels relevant but is not.
Spotting it in practice
To detect a red herring, restate the original question and ask whether the response actually addresses it. Politicians answering a difficult question by raising an unrelated achievement, or a student challenged on a missed deadline who instead complains about the assignment’s difficulty, are classic cases. The test is relevance: if removing the diverting material leaves the original argument exactly where it was, the material was a red herring. Naming the diversion and returning to the question is the standard response.

Common misconceptions
What people often get wrong
Often heard: A red herring is the same thing as a straw man.
Actually: They are distinct. A straw man distorts the opponent’s argument and attacks the distortion; a red herring abandons the argument entirely by switching to an irrelevant topic. Both are fallacies of relevance, but only the straw man involves misrepresenting what was said.
Often heard: If a point is true, it cannot be a red herring.
Actually: A red herring can be perfectly true and still fallacious. The flaw is irrelevance, not falsity. Raising a true but unrelated fact to draw attention away from the question in dispute is exactly what makes the move a red herring.
Often heard: Red herrings only appear in fiction or detective stories.
Actually: The literary "false clue" sense is related but separate. As a logical fallacy, the red herring appears constantly in debate, advertising and politics whenever an irrelevant distraction is used to avoid answering the actual issue.
