# Low-profile speculation Part of [The AI Tells Index](https://feedsquad.com/ai-tells). A tell signals low effort. It does not identify an author. Skilled writers produce every shape listed here, some of them daily, and automated detectors misread those writers for it at rates measured above 60 percent on non-native English prose. Nothing in this index proves that a machine wrote anything. Read an entry as one piece of evidence to weigh against the false-positive notes printed beside it. ## Facts - Id: low-profile-speculation - Category: Semantic (semantic) - Subcategory: gap-narration - Also known as: maintains a low profile, little is known about - Status: Active. Currently signals low-effort writing. - Severity: medium - Evidence grade: community-observed (named by practitioners, no formal measurement exists) - Languages: en - Added: 2026-08-15 - Updated: 2026-08-17 - Page: https://feedsquad.com/ai-tells/low-profile-speculation ## Description A gap in the sources is narrated as a fact about the subject. Nothing was found, so the text reports that the person keeps to themselves. The claim is about the research and it arrives dressed as biography. ## Why it reads as machine-written Retrieval that returns nothing produces a sentence anyway, and the cheapest sentence available says the absence is meaningful. Wikipedia files this with the behaviour it describes around training windows, noting that where a system fails to find sources it may state that the information is not publicly available and then speculate about what it likely is and why that matters. Both halves are invention, including the claim that nothing is documented. The check is one question: is a source attached to the absence. ## Detection Type: deterministic (a regular expression, run as written) Scope: sentence ECMAScript regular expression. The build validator compiles it and tests it against this entry's own specimens. ```regex (?:\b(?:maintain|maintains|maintained|keep|keeps|kept)\s+a\s+(?:relatively\s+|famously\s+|notably\s+|fairly\s+)?low\s+profile\b)|(?:\blittle\s+is\s+(?:publicly\s+)?known\s+about\b)|(?:\b(?:keeps|prefers\s+to\s+keep)\s+(?:her|his|their)\s+(?:personal\s+(?:life|details)|private\s+life)\s+(?:private|out\s+of\s+the\s+public\s+eye)\b)|(?:\b(?:is|are)\s+not\s+widely\s+documented\b) ``` Flags: gi ## Examples Constructed specimens. Written for this index. Never quoted from anyone's posts. ### Specimen 1 Before, exhibiting the tell: > Little is known about Rautio's early career, and she appears to maintain a low profile outside her professional work. Her education is similarly undocumented, which suggests she preferred to let the work speak for itself. What can be said is that she has always chosen substance over visibility, and those who have worked with her seem to have respected it. After, repaired: > We could not document Rautio's career before 1998. The trade register lists her first company from that year and nothing earlier. The polytechnic alumni office confirms her degree and holds no record of anything before 1996. We wrote to her former employer on 3 June and had no reply. The gap is in our research and we are stating it as ours. Note: The subject and the institutions around her are invented for this specimen. Every sentence after the first turns another empty search into a character trait. The repair converts a claim about a person into a claim about the search, which is the only claim the writer can support. ## False positives Who legitimately writes this way. Biographers of private people write this sentence all the time, with sourcing behind it. Someone who has declined every interview for thirty years does keep a low profile, and saying so is reporting rather than speculation when a source supports it. Obituary writers and archivists describe documented absences as a matter of course, and historians of the poor and the colonised write about record gaps because the gaps are the subject. Legal and safeguarding contexts require exactly this wording. What separates the two is whether a citation sits next to the sentence. A reviewer who flags a sourced one has misread this entry. ## Model attribution Wikipedia groups it with the training-window behaviours, which cover older systems with a fixed cutoff and newer ones whose retrieval step returns nothing. No vendor attribution is available. ## Platform notes - wikipedia: Listed among the signs that a passage was produced without sources, alongside the older boilerplate about training windows. The page notes that the speculation extends to the claim that the information is undocumented. ## Sources 1. Wikipedia: Signs of AI writing https://en.wikipedia.org/wiki/Wikipedia:Signs_of_AI_writing (tier: community; accessed 2026-08-14) ## Status history Ids are permanent. A retired tell keeps its id and its page. - 2026-08-15, Active: Wikipedia names the phrasing and quotes dated article revisions using it where no source existed. One source, so the grade is community-observed. The check is cheap, which is why the entry is deterministic rather than a rubric. ## License CC BY 4.0. https://creativecommons.org/licenses/by/4.0/ Attribution: The AI Tells Index, feedsquad.com/ai-tells Reuse the data, including commercially.
