Research opportunity · Individual gain, collective narrowing? Does AI make science, creative work and shared knowledge more alike?
Does language-model use narrow what whole fields study, including the social sciences?
In short: has this been done?
Related work: Partly addressed. Related studies cover parts of this question; what they leave open is set out below. Only a first-pass search has been done, so it is not yet known whether a fuller search would find a study that does the whole design.
How far checked: First-pass screen only. A first-pass AI web search on 15 October 2026. No deeper check yet. Every search and check so far was done by AI; no person or domain expert has checked them yet.

Question
Since language models became widely used in 2023, has the range of topics covered by papers from adopting researchers shrunk relative to non-adopters, at the level of whole fields, and does the answer differ between the natural and the social sciences?
Gap type: Not yet measuredA PhD projectLow to medium costRelated work: Partly addressed
Why it matters
The strongest field-level evidence of narrowing comes from AI used as a research method in six natural sciences, mostly before chat assistants, and its authors exclude the social sciences. Studies of the language-model era find adopters drawing on more diverse prior work and scientists in general spreading across more fields, but they measure individuals, not the space a field covers. Without the field-level measure for language-model use, the debate cannot say whether the narrowing position (P1) or the concentration position (P2) describes the present.
The debate lists this among what we still do not know: Does language-model use narrow what fields study, measured as section 1 measured AI methods in the natural sciences?
Evidence that motivates it
- In the same natural-science corpus, AI-augmented research was associated with a 4.63% smaller median collective knowledge extent and 22% less follow-on engagement among papers citing the same work, while each AI paper’s own family of citing papers was 3.46% more spread out; the authors link the contraction to AI work clustering where data are abundant. (LD09-SL-C02 v1.0)
How this study uses it: AI-augmented natural-science research covered a 4.63% smaller knowledge extent, associated with data availability; the authors exclude the social sciences. - Across arXiv, bioRxiv and SSRN preprints (2018–2024), authors whose abstracts first showed signs of language-model writing then posted 36.2%, 52.9% and 59.8% more papers respectively; for their manuscripts, more complex writing went with lower odds of publication, the reverse of the pattern for human-written ones; and adopters drew on “more diverse prior work”, being 11.9% more likely to cite books and citing younger documents. (LD09-SL-C05 v1.0)
How this study uses it: Language-model adopters posted more preprints, were more likely to cite books and cited younger documents. - Among 775,323 scientists with full-text papers in PubMed Central, individual research portfolios spread across more fields after 2022: field entropy rose from 0.55 in 2022 to 0.71 in 2025 and the share entering a new field from 30.4% to 35.5%, more so for scientists in non-English-speaking low- and middle-income countries; the authors call the design descriptive. (LD09-SL-C07 v1.0)
How this study uses it: Individual portfolios spread across more fields after 2022, in a descriptive design. - By February 2024 an estimated 17.5% of sentences in computer-science abstracts on arXiv were substantially modified by language models; the share was higher in papers closer to their nearest peer, a proxy for more crowded research areas (22.2% against 14.7% for less similar papers). (LD09-SL-C09 v1.0)
How this study uses it: Language-model-modified sentences were more common in crowded research areas.
Each claim is shown as it read when this version was published.
A possible design
Classify papers in open full-text and abstract corpora (arXiv, bioRxiv, SSRN, PubMed Central and social-science repositories) by estimated language-model use from 2018 on, using a distribution-level estimator rather than per-paper detection. Apply the knowledge-extent and follow-on-engagement measures of the natural-science study to adopters and non-adopters within field and year, adding economics, sociology, psychology and political science. Exploit differences in the timing of institutional access to language models (for example national blocks or licence roll-outs) for a difference-in-differences design, and test whether data availability explains any contraction.
Data needed
Open abstract and full-text corpora with field codes; a validated distribution-level estimator of language-model text; dates of institutional or national access to chat assistants; text embeddings frozen at one version.
Feasibility
A PhD project. Low to medium; the corpora are public and the measures need modest compute, but validating the estimator for social-science writing needs hand-labelled samples. Per-paper detection is unreliable, so adoption must be estimated at group level; dating adoption by first flagged paper creates artefacts (LD09-SL-C06) and should be avoided.
Has this been done?
Partly done already: related work covers some of this question (first-pass screen of 15 October 2026; not yet checked in depth).
No study was found that applies field-level breadth measures to language-model use or to the social sciences. Nearest work measures article-level novelty after 2022 in one field without observing model use, the distinctiveness of individual grant proposals, the prevalence of model-modified text by field, or individual scientists' field-switching.
How strong this evidence is
- Who searched and checked: no checker is recorded beyond the first-pass screen, which was part of the AI drafting (Claude (SocioLens Project Lead), AI-drafted from the LD-09 debate). Every check so far was done by AI; no person or domain expert has checked it yet.
- What was read: 4 of the 5 nearest works below were judged from an abstract, summary or search listing only; each is marked. Not every entry says how much of the work was read.
- Where the search could not reach: Screened by web search (3 queries) and arXiv queries on the date shown; Scopus, Web of Science and Dimensions were not searched, and science-of-science conference proceedings were not checked. Absence of a hit is not proof that the work does not exist.
- Before building a project on it, run your own search in a scholarly database such as Scopus, Web of Science, Google Scholar or SSRN.
