Quote mining extracts a fragment of what someone said or wrote and presents it in a way that misrepresents their actual meaning — often reversing it. Also called contextomy or simply quoting out of context, it is a concealment tactic that weaponizes the source’s own words: by borrowing the credibility of a real, named authority, the framer makes a distorted position look authoritative. The classic forms include the cropped movie blurb ("…a triumph…" pulled from “far from a triumph”), the scientist quoted as doubting their own field, and the opponent shown “admitting” the very thing they were arguing against.
The mechanism is the same omission that drives context collapse, narrowed to language. A qualifying clause, a conditional (“if we assume, wrongly, that…”), or the setup identifying a view as one being rebutted is snipped away, and an ellipsis often stands where the meaning-bearing words used to be. Because the surviving words are genuinely the source’s, the fragment passes casual inspection; the reader has no visible signal that the sentence originally ran the other way. The distortion holds only as long as no one opens the original.
That is also the defense. Treat every quote as a checkable claim about its source, not as settled fact. Read the sentences around it, interrogate every internal ellipsis as a possible edit point, and confirm the source is asserting the position rather than describing a hypothetical or an opponent’s argument. When no openable citation is offered, withhold belief. A faithful quotation reads the same in context; a mined one falls apart the moment the full passage is restored.
