In history a fabricated detail looks exactly like a real one, because the whole subject is made of specifics: dates, names, quotations, archive references, the position a particular historian took in a particular book.\n\nThose specifics are the weakly-represented category from Module 1. Which means history is the subject where the mechanism bites hardest and where the failure is hardest to see without checking.\n\n## The four fabrications to expect\n\n**Invented quotations.** The most common and the most damaging. A plausible line, attributed to a real figure, in their register. Famous historical figures attract these enormously: many quotations widely attributed to Churchill, Gandhi, Lincoln or Einstein were never said by them, and that misattribution is in the training data too, so the model reproduces it confidently.\n\n**Composite events.** Two similar events blended into one, with a date from one and details from the other. Reads perfectly. Wrong.\n\n**Invented historiography.** *Historian X argued that...*: where X is real, the position is plausible for their school, and they never wrote it. Markers in history departments spot this immediately, because they know the literature.\n\n**Date drift.** Confident dates that are one or two years out. Especially bad for anything before 1800, and for events outside western Europe and North America, where the training text is thinner.\n\n## The check, which is the discipline of the subject anyway\n\nHistory already has the answer: go to the source. What is new is that you must apply it to a category of claim that did not previously exist: the claim that arrives already footnoted-looking.\n\n- **Every quotation gets traced to a primary source or a scholarly edition.** If you cannot find where it was said, written or recorded, you do not use it. A quotation you found only in secondary repetition is not evidence.\n- **Every historian's position gets traced to the book or article**, with a page number, that you have opened.\n- **Every date gets checked** against a reference work.\n\nThe free path is good here. **Google Books** for full-text search of published works, which is excellent for finding whether a quotation appears anywhere before a given year. **Internet Archive** and **HathiTrust** for out-of-copyright texts. **JSTOR** has free limited reading; your library has the rest. National archives are increasingly digitised and free: the UK National Archives, the US National Archives, and many national and state collections.\n\n## The bibliographic test for a quotation\n\nA specific and effective move. Search the exact phrase in Google Books, restricted by date. If a quotation attributed to a nineteenth-century figure first appears in print in 1987, it is a twentieth-century invention. This is how the quotation-checking community works and you can do it in two minutes, free.\n\n## Where the model earns its place in history work\n\nSubstantially, and it is worth being clear about it:\n\n- **Explaining a historiographical debate's shape**: what the positions are, roughly why they differ. Then go and read the actual historians.\n- **Context for a primary source you are reading.** Paste the source; ask what a reader at the time would have understood by a term. Verify anything specific.\n- **Translating and paraphrasing archaic or foreign-language text**, which is strong, with the caution that a translation you cannot check is a claim you cannot verify.\n- **Arguing against your thesis**, which is the essay move from Module 2 and is worth more in history than almost anywhere else.\n- **Making your prose clearer**, at sentence level, on writing you produced.\n\n## Source criticism has not changed\n\nThe questions you were taught still apply and now apply to a new kind of text. Who produced this? For what audience? What did they gain by saying it? What would they not have known? What is missing?\n\nRun those on a model's output and the answers are unusual: produced by a statistical process, for you, gaining nothing, knowing whatever was in its training text, missing everything specific that was rare. That is not a source. It is a starting point with no provenance, and treating it as a source is the single mistake to avoid in this subject.\n\n## The one that gets people caught\n\nA fabricated citation in a history essay is the most common academic-integrity trigger in humanities departments, and it usually was not intended as dishonesty: the student believed the reference was real. The intention does not change the outcome. **Open every source.** Ten minutes with a library catalogue is the entire defence, and it is also just doing the subject properly."},"check":{"question":"A student finds a striking quotation attributed to a nineteenth-century reformer.
