Yes — and it's one of the clearest failure modes of these tools. Direct quotations, standard disciplinary terminology, methods sections and formal register are all highly predictable text, and predictability is the only thing a detector measures.
A quotation is, by definition, text that already exists. Of course it scores as unsurprising.
What tends to score highest
- Block quotations. Properly attributed, correctly formatted, and statistically indistinguishable from any other pre-existing text.
- Fixed disciplinary phrasing. Legal tests, clinical criteria, standard definitions, statutory wording. There is one correct way to state them, so any correct statement is the predicted one.
- Methods and procedure sections. Deliberately formulaic, because reproducibility demands it. Lab reports and psychology write-ups score high routinely.
- Formal hedged register. The impersonal, cautious voice you were taught to write in is the single most conventional prose style in existence.
Law, medicine and the sciences — disciplines where precise, conventional, repeated phrasing is a requirement rather than a stylistic choice. Writing the thing correctly is what raises the score.
Does the detector strip quotations first?
Don't assume so. Turnitin's similarity report can be configured to exclude quoted material — that's a long-standing setting your department controls. The AI indicator is a separate report and doesn't work the same way, and how quotations are handled isn't something you can see or control from the student side.
Which produces an unpleasant edge case: a well-researched, quotation-heavy essay can score higher than a thin one with no sources in it.
What not to do about it
Don't cut quotations you need, and don't paraphrase a source to avoid quoting it. Both damage the essay for a marker in order to satisfy a tool that shouldn't be deciding anything on its own — and paraphrasing to disguise a source's wording is closer to a misconduct problem than the quotation ever was.
Do keep quotations doing real work: introduced, attributed, and followed by your analysis of them. That's what a rubric rewards regardless, and a quotation surrounded by your own argument is a smaller share of a longer document.
If a flag lands on quoted material
That's a strong position, not a weak one. Point at the passages: they're attributed, they're in your reference list, and the source exists. A flag on correctly quoted text is a demonstration that the tool measures predictability rather than authorship. The general process is in what to do if you're wrongly accused, and the underlying mechanism in why your own writing looks AI-generated.
