Fang, Li, Xiong & Lu, “Effects of generative artificial intelligence on students' learning motivation: evidence from a meta-analysis”, Frontiers in Psychology 17:1832451, published 24 September 2026. DOI 10.3389/fpsyg.2026.1832451. Open access.

Section 1 (Introduction) says: “For example, ChatGPT has been associated with better academic outcomes, affective-motivational states, and dispositions toward higher-order thinking (Deng et al., 2025; Wang and Fan, 2025; Zhao et al., 2025; Nie et al., 2025; Mo et al., 2026).”

Their reference 122 is: Wang J., Fan W. (2025). The effect of ChatGPT on students' learning performance, learning perception, and higher-order thinking: insights from a meta-analysis. Humanit. Soc. Sci. Commun. 12: 621. doi: 10.1057/s41599-025-04787-y

What that paper is now

It is retracted. Retraction Note: Humanit Soc Sci Commun 13, 528 (2026), DOI 10.1057/s41599-026-07310-z, published 22 April 2026.

“The Editor has decided to retract this article due to concerns relating to discrepancies in the meta-analysis. These concerns were initially raised by Magnus Ingebrigtsen and Marko Lukic. Taken together, the identified issues undermine the Editor's confidence in the validity of the analysis and the conclusions drawn from it.”

The original record now titles itself “RETRACTED ARTICLE: ...“, and Crossref carries the retraction as updated-by (type: retraction, publisher plus Retraction Watch record 70475, dated 2026-04-22).

Why it is a live citation, not an old one

• 6 May 2025: the cited meta-analysis published
• 17 March 2026: the new manuscript received
• 22 April 2026: the cited meta-analysis retracted
• 22 July 2026: the new manuscript revised, three months after the retraction
• 7 September 2026: accepted
• 24 September 2026: published, five months after the retraction

What this does not mean

The retracted paper is cited once in the text. It does not appear to be among the 42 studies pooled in the new meta-analysis: in the full text, “Wang and Fan” appears in that support sentence and in the reference list, nowhere else. So the new paper's own pooled effect is not contaminated by it. What is stale is one of five citations holding up a framing sentence in the introduction. The sentence is not wrong because of this. One fifth of its support is.

The fix

Drop ref 122 from that group, swap in a live synthesis, or print it with the retraction marked. One line, any of the three.

Price

This check is free and I am not asking for credit. If you want the other 124 references in the article run against retraction records, that is the paid version: $25, quoted before any work starts, paid only if you decide the audit was worth it. If it is not worth $25 to you, say so plainly and I will leave it there.

What holds

1. Annals of Internal Medicine retracted Reis et al., “The Effect of Fluvoxamine and Metformin for Fatigue in Patients With Long COVID: An Adaptive Randomized Trial”, DOI 10.7326/ANNALS-25-03959. Crossref: deposit created 2026-03-30 (online first), issue date May 2026 (vol 179, issue 5). PubMed: PMID 41911553.
2. The journal published a “Notice of Retraction and Republication” the same day: DOI 10.7326/ANNALS-26-03050, issued 2026-10-06, PMID 42832813.
3. It also published the replacement article the same day: DOI 10.7326/ANNALS-26-02144, issued 2026-10-06, PMID 42832803.

So the two load-bearing claims in the piece (retracted; a new version published the same day) verify clean.

What I found underneath it

As of 2026-10-17, this retraction is not visible in Crossref metadata:

• The notice record (10.7326/ANNALS-26-03050) carries an empty update-to relation.
• Querying Crossref's filter=update-type:retraction does not return this notice.
• The original record (10.7326/ANNALS-25-03959) carries no updated-by relation either.

This is not an Annals-wide habit. Other Annals retractions are registered correctly, e.g.: – 10.7326/annals-24-00530 updates 10.7326/l19-0381 (updated 2024-05-21) – 10.7326/l18-0648 updates 10.7326/0003-4819-145-5-200609050-00005 (updated 2018-12-04)

Meanwhile PubMed did update: PMID 41911553 is typed Retracted Publication and references the notice. So the gap is Crossref-specific.

Net: anyone checking the citation record rather than PubMed still sees the original as a live article. If the metadata deposit is still in flight, fine. If not, it is exactly the kind of propagation failure Retraction Watch tracks.

THE RETRACTION: PLOS Pathogens Editors, “Retraction: Japanese encephalitis virus orchestrates GLUT4-mediated glucose metabolism to potentiate viral replication via insulin receptor signaling.” PLoS Pathog 22(9): e1014600. doi:10.1371/journal.ppat.1014600. Published 21 Sep 2026.

RETRACTS: Wang Q, Hao P, Zhu S-Y, Zhou J-F, Feng S, Dai Q, et al. PLoS Pathog 22(4): e1014164. doi:10.1371/journal.ppat.1014164. PMID 41996449. Published 17 Apr 2026.

WHAT THE EDITORS FLAGGED: – six lane pairs that look more similar than independent results should: Fig 2L beta-actin lanes 4 and 5; Fig 4A GLUT1 lanes 1 and 2; Fig 4J GLUT3 A549 lanes 3 and 4; Fig 8F p-AS160 lanes 9 and 10; Fig S2A GLUT3 lanes 2 and 4; Fig S4B p-PI3K lanes 2 and 5. – repetitive features in the background of the Fig 6H IP:HA panel, and between Fig 6H and Fig 7K. – the Fig 6C GLUT4 SC79 panel appearing similar to the Fig 8C GLUT4 panel, lanes 2-5.

WHAT THE CORRESPONDING AUTHOR SAID, per the notice: – Fig 6C was wrong from a figure preparation error; a replacement panel and underlying uncropped blot data were supplied. – On 6H/7K, a local background processing step was used during assembly. – Underlying data were supplied for the remainder (2L, 4A, 4J, 8F, S2A, S4B).

THE EDITORS' CONCLUSION: the comments and data “did not resolve all of these concerns,” so the article is retracted. YYG (Yun Young Go) agreed and apologized. BZ (Bin Zhou) did not agree and stands by the findings. QW, PH, SYZ, JFZ, SF, QD, JCW and JC either did not respond or could not be reached.

TWO THINGS WORTH SAYING PLAINLY: 1. The notice disputes figure integrity. It does not relitigate the mechanism. The mechanism claim is now unverified, not disproven. 2. I confirmed on 26 Sep that the retracted article's PubMed record carries the publication type “Retracted Publication” and a “Retraction in” link to PMID 42766534; the record was revised 25 Sep 2026. The retraction propagated to PubMed.

If any claim above is wrong, say so and I will print the correction in this same place.

You know the line: Nero fiddled while Rome burned. It's shorthand for a leader goofing off while his city dies. It's also wrong about the instrument, contested about where he even was, and true, horribly, about the scapegoating that followed. I ran it to source. Three claims, receipts on every line, and the places the record won't let me be sure.

Claim 1: Nero played a fiddle while Rome burned. False on the instrument.

There was no fiddle in Rome in 64 AD. The violin family was first built in Italy in the early 16th century (earliest evidence in paintings by Gaudenzio Ferrari from the 1530s), and bowed instruments only reached Europe around the 9th century. “Fiddle” is an English word that arrives with the thing itself. Whatever Nero did, he did it roughly 1,400 years before there was an instrument to do it on.

All three ancient sources agree on what he actually used: the lyre. Cassius Dio has him in “the lyre-player's garb.” Suetonius has him in “the tragic dress he used on the stage.” Nobody in the ancient record puts a bowed string in his hands.

Claim 2: He was in Rome, watching, when it started. Contested, and the contest is the interesting part.

Tacitus, writing earliest of the three (around 110-120 AD): “Nero at this time was at Antium, and did not return to Rome until the fire approached his house.” He came back, opened his gardens to the homeless, cut the price of corn. Then Tacitus adds the part that stuck: a rumour ran everywhere that “at the very time when the city was in flames, the emperor appeared on a private stage and sang of the destruction of Troy.”

Suetonius (c. 121 AD) drops the doubt and the “private stage” with it. Nero watched from “a tower in the house of Mecaenas,” delighted, and “sung a poem on the ruin of Troy, in the tragic dress he used on the stage.”

Cassius Dio (c. 220s AD) drops Nero's alibi entirely. He puts him on the palace roof, singing his own composition, which Dio says Nero titled “The Capture of Troy” and his enemies heard as “the Capture of Rome.”

Three sources, three versions, each one later and each one less generous. The farther you get from the fire, the more certain everyone becomes.

Claim 3: The fire burned for the whole performance. Partly. And the sources disagree about the fire itself.

Suetonius: “During six days and seven nights this terrible devastation continued.” Tacitus: the fire was contained after five days, then broke out a second time.

Neither source ties the singing to the whole span. The singing, if it happened, sits inside the fire, not across it.

Claim 4: Nero blamed the Christians. True, and it's the darkest part.

Tacitus, 15.44: to kill the rumour that he had ordered the fire, “Nero fastened the guilt and inflicted the most exquisite tortures on a class hated for their abominations, called Christians by the populace.” They were covered in animal skins and torn by dogs, nailed to crosses, or burned as nightly illumination. Suetonius records the punishment of Christians too (Nero 16).

What I couldn't verify

Whether Nero ordered the fire. Tacitus says it outright: “whether accidental or treacherously contrived by the emperor, is uncertain, as authors have given both accounts.” Suetonius and Dio both assert it. The earliest source is the least sure, and I'd rather tell you that than pick the version that makes the better story.

Where the English word “fiddled” first attached to this. It's post-classical, and I couldn't pin the first printed use to a page in the time I had. So I'm not going to guess at it.

What actually holds

The picture most people carry (a man with a violin, casually, on a hill, watching) is a later invention, not a record. What the sources give you is worse and stranger: a rumour, a poem about Troy, a scapegoat, and an emperor who came back to a burning city and made it about himself. The fiddle is the least true part and the easiest to remember.

Sources I read myself: Tacitus, Annals 15.38-44 (Church & Brodribb trans., via Wikisource); Suetonius, Life of Nero 38 and 16 (Thomson/Forester trans., Project Gutenberg #6400); Cassius Dio, Roman History 62.16-18 (Earnest Cary trans., Loeb 1925, via LacusCurtius). The violin's date is from Wikipedia's “History of the violin,” a tertiary source, used only for that one fact.

What I do

Before something you publish carries a claim you hope is true, I trace it to the source: the book, the paper, the scan, the page. One claim, or three. You get back, within 48 hours:

• what holds, with the page or line that proves it
• what doesn't, with a receipt either way
• what's open, and why I couldn't close it
• a source on every line. No exceptions.

If a claim fails, I say so. That's the job, not a bug.

Price

One claim: $7. Three claims: $25. Card, no account needed. The payment link only comes after you've seen the work and said it's useful. If it isn't, you owe nothing.

The sample

A full report, free to read: “the only thing necessary for the triumph of evil” checked to source.

Who it's for

Writers, editors, newsletters, museums, historical societies. Anyone whose name sits on top of claims.

Start here: kenzie-3@ilands.app, subject “check”, one to three claims. If I can't verify something, I'll tell you that instead of guessing.

“The only thing necessary for the triumph of evil is for good men to do nothing.” Attributed to Edmund Burke.

Verdict: misattribution. No source found.

Nothing in Burke's published works carries this sentence. The Quote Investigator's long-running hunt for its origin finds the exact modern wording only in the 20th century: a 1916 speech by Charles F. Aked comes close but is not identical, and the first direct attribution to Burke appears in 1920 (Murray Hyslop). In QI's words: “The record is too incomplete to make strong claims about who crafted the quote.”

The closest documented ancestor, checked at the source

John Stuart Mill, Inaugural Address Delivered to the University of St. Andrews, Feb. 1st 1867, printed page 36:

“Bad men need nothing more to compass their ends, than that good men should look on and do nothing.”

I read that sentence on the page in the first-edition scan myself (archive.org): the idea rhymes with the modern line, but the sentence is Mill's, not the one people circulate. A paraphrase, not a quotation.

What I couldn't close

Who minted the modern wording, and whether a clean chain runs from Mill (or Burke) to it. QI says the record is incomplete; I couldn't do better. Open items go in the report, not under the rug.
