Do you trust that AI-assisted research papers are as reliable as traditional human-authored studies?
SSRN removed 257 academic papers and froze accounts linked to Nicholas Polson in August and September 2026. Polson confirmed he utilized artificial intelligence tools to produce the research, some of which were published without mandatory disclosures.
Why it matters
The incident highlights the ongoing challenge of maintaining academic integrity as AI-driven output contributes to a massive increase in scholarly submissions. Journals are now struggling to verify citations and authorship in an era where AI tools allow for prolific, automated research publication.
A study of 3,200 peer-reviewed papers found that 2 percent contained at least one unverifiable reference. This rate of inaccuracy in citation checking coincides with an Elsevier report showing a 68 percent surge in total journal submissions between 2021 and 2025.
The players
Nicholas Polson
An academic at the University of Chicago who authored or co-authored over 200 papers and 14 books this year using AI tools.
SSRN
A preprint repository owned by Elsevier that hosts academic research and has recently implemented stricter account controls.
Elsevier
A major academic publishing company that reported a 68 percent increase in submissions between 2021 and 2025.
The details
The platform acted after researchers noted unusual submission activity and a lack of required disclosures for AI-assisted work. Researchers often utilize AI to assist with tracking prior research and analyzing data, but the practice can lead to hallucinated or unverifiable citations. The sheer volume of material, with 14 books and over 200 papers released by one individual in a single year, prompted the scrutiny of these automated workflows.
Timeline
1998: A flawed vaccine study was published in The Lancet.
2021-2025: Elsevier saw journal submissions increase by 68 percent.
2022: ChatGPT became available to the general public.
August/September 2026: SSRN removed 257 papers and froze accounts.
Fall 2026: Polson is scheduled to teach two classes.
The Tech Race
The SSRN incident echoes the 1998 flawed vaccine study in The Lancet, marking a similar failure in the gatekeeping of scientific literature. Current editorial workflows are struggling to maintain this standard as generative models allow authors to bypass traditional research bottlenecks.
The removal of these papers impacts researchers and students who rely on the SSRN platform for credible, up-to-date academic insights. Users should verify all citations in papers published within the last two years, as the increase in automated submissions has complicated standard peer-review processes.
The takeaway
The sheer volume of papers produced by a single author serves as an early signal for journals to implement more rigorous automated screening of AI-generated content. Readers should watch for new guidelines from Elsevier regarding author disclosure requirements for AI-assisted research.
What happens next
Nicholas Polson is scheduled to release two additional books in the coming months, which may be subject to further scrutiny following the removal of his previous work.
