A claim worth checking: “science and technology are becoming less disruptive.” It comes from a January 2023 Nature cover paper, and it has been repeated in 300+ news stories and at least 16 policy documents. On 12 August 2026, Nature published a correction that mostly takes it apart. Here is what each side actually says.

The original claim

Park, Leahey & Funk, Nature 613, 138-144 (2023). Using the CD index on almost 45 million papers and 3.9 million patents, the authors found that later work was increasingly consolidating rather than breaking with the past. Reported declines across fields: 91.9% (social sciences) to 100% (physical sciences) for papers; 78.7% (computers and communications) to 91.5% (drugs and medical) for patents, 1980-2010.

The correction

Holst, Algaba, Tori, Wenmackers & Ginis, Nature 656, E7-E13, 12 Aug 2026. They tried to reproduce the study from open data and found a large peak of papers carrying the maximum disruption score, a peak that is absent from the published histograms. The reason:

  • The CD index hands a paper its maximum score when later work cites it but none of its references. If a database records no references for a paper, the paper gets that maximum score anyway, on a single citation within five years.
  • In the SciSciNet database, 97% of maximum-score papers had zero recorded references. The team pulled 100 of them at random and checked the source documents: 93 did list references. The score was a database artefact, not a breakthrough.
  • Older records are patchier, so false maxima were common early and rare later. That gradient alone manufactures a decline. In the study's largest dataset, the artefacts account for 93% of the reported fall between 1945 and 2010.
  • The published histograms hid the peak because of a bug in the seaborn plotting library that silently dropped the largest values from the plot, while those papers stayed in the analysis. In Web of Science alone, the corrected plot contains 972,161 maximum-score papers.

The critique was submitted in October 2023 and accepted in June 2026, 32 months. In that window the original paper was cited over 1,000 more times.

The authors' reply

Park, Leahey and Funk, in the same issue, argue that the decline stays statistically significant under alternative specifications, and question the composition of the reanalysis dataset.

What to believe

Not the headline numbers. With this measure, as Ginis puts it, “we cannot make conclusive statements about whether science is getting more or less disruptive.”

One caveat against over-correcting: an independent preprint inventory (arXiv:2602.05140, Feb 2026) catalogs 105 studies on this question and reports the decline broadly, including measures that use no citations at all (text similarity, firm displacement, product networks, audio and visual embeddings). Those are not touched by this artefact. So “the whole idea is dead” is too strong. What is dead is quoting the 2023 figures as settled.

Short answer: nobody has shown that it is, and one new paper argues it isn't.

What the company says. Reflect Orbital, whose Eärendil-1 mirror was licensed by the FCC in July, states in its site FAQ: “The light is not bright enough to start fires or harm eyes, even when viewed through a telescope, and cannot be concentrated past maximum natural sunlight irradiance.” (reflectorbital.com, “Is it safe?”, checked 21 Sep 2026.) The same page says brightness is adjustable “from full moon to full noon,” and lists future levels up to 5,000 lux for minutes by 2030 and up to 36,000 lux for hours by 2035.

What the preprint says. Salvador Bará, “Retinal hazards and glare from space mirrors,” arXiv:2609.20878, submitted 16 Sep 2026 (preprint, not peer-reviewed). Working from current eye-safety and glare standards, the paper finds:

  • Telescopic observations of single mirrors “appear to pose a significant risk of photochemical retinal hazard,” with the risk higher for vulnerable populations.
  • Unaided-eye viewing keeps retinal risks low (photochemical and thermal), but disability glare may be unacceptably high, affecting awareness and response in critical visual operations.
  • Several mirrors at once in the visual field significantly increase all types of hazards.
  • More information is needed on the transient flashes that occur while a mirror slews.

Why the two claims don't cancel each other out. The company's sentence is an assurance, not a calculation. As far as I can find, it has not published the irradiance numbers behind “even through a telescope.” The preprint is a standards-based estimate, but it is not peer-reviewed and it models mirrors in general rather than one specific licensed satellite. So the honest state of the question is unresolved, and the company's blanket claim is the weaker of the two, because a claim with no published numbers cannot be checked by anyone.

What I would want before believing either side. The actual spectral irradiance at an observer's eye from Eärendil-1, unaided and through a telescope, compared against the photochemical and thermal limits the paper cites. Until someone publishes that, “safe through a telescope” is a slogan, not a finding.

Bottom line: don't point a telescope at an orbital mirror on the strength of a safety line. The one published analysis of the question lands on “significant risk” through a telescope.

Another sample, the family-lore kind. If your family has a version of this story, the last section is a method you can run yourself.

The claim: “Nobody at the port could pronounce it, so the clerk changed our name on the spot.” One phrasing of the most common story in American family lore. Ask a dozen families with immigrant roots: several will have a version.

What the record trail shows. – Ellis Island inspectors never wrote down arriving immigrants' names. The only list of names was the ship's manifest, filled out by steamship company employees in Europe when the passenger bought the ticket, before the voyage began. – Inspectors compared people to the manifest; they did not rewrite them. If anything, they corrected mistakes: when a correction was made, “the original name was never entirely scratched out and remained legible” (The Encyclopedia of Ellis Island). – The historians are blunt: “Nearly all name change stories are false. Names were not changed at Ellis Island” (Vincent J. Cannato, American Passage: The History of Ellis Island). – The changes were real, but they were later and voluntary. Immigrants changed their own names, sometimes before migrating and more commonly after arriving: to sound more American, to fit the neighborhood, or because it was good for business. Some recorded the change when naturalizing; many never recorded it at all (New York State did not require it). – Misspellings were born overseas. Ticket clerks wrote names by ear, and transliteration between alphabets did its own damage. By the time anyone reached the island, the spelling had usually settled on paper.

Where the story comes from. To an immigrant, “Ellis Island” was not one morning. It was the whole arrival: the lines, the city, the first job, the first apartment, the new spelling of a name. Decades later, the details collapse into a single image, and the story settles where it feels true. As immigration historian Marian L. Smith puts it: “When recalling their immigration decades before, many immigrants referred to the entire experience as 'Ellis Island.'”

The one documented case (and why it still doesn't count). In 1908, a passenger crossed on the S.S. New York as Frank Woodhull. The manifest shows the name crossed out and replaced with Mary Johnson; Woodhull was held for special inquiry when inspectors learned he had traveled “in male attire,” and was released as a desirable immigrant. He walked off the island and lived under the name he had chosen. The one case historians keep pointing to shows the same thing as all the others: Ellis Island corrected toward the legal name, kept the original legible, and could not impose a name on anyone.

Check your own family's version. 1. Find the name on the manifest (ship and arrival date). That spelling is the anchor; everything else gets compared to it. 2. Follow the name forward through census decades and city directories, and mark the year it changes. 3. Check naturalization papers. Name changes often appear there, and sometimes nowhere at all. 4. Read the change back to its real source: usually a ticket office, a school register, an employer, a courthouse, or a decision someone made. Ask the oldest relative when they first heard the story, and from whom.

Sample check, posted so you can see what one looks like.

The claim: “The Great Wall of China is the only man-made object visible from space” (and its louder cousin: “visible from the Moon”).

Verdict: fails as told, both versions, with one small true piece inside: it can be photographed from orbit. The more interesting part: the myth predates spaceflight by two centuries, so nobody who repeated it could have checked it.

The paper trail starts in 1754. The earliest known version is a 1754 letter by the English antiquary William Stukeley, who likens Hadrian's Wall to “the Chinese Wall... [which] may be discerned at the Moon.” By 1895 it's a travel-book commonplace: “the only work of human hands on the globe visible from the Moon.” A 1932 Ripley's Believe It or Not! strip turns it into a catchphrase. First human spaceflight: 1961.

From the Moon: no. NASA, 2005: “It certainly isn't visible from the Moon.” Neil Armstrong, asked after Apollo 11, described continents, lakes, colors, and no man-made structures. Even the Moon version was never anything but repetition.

From orbit, naked eye: barely, rarely. NASA: the wall “generally isn't [visible], at least to the unaided eye in low Earth orbit.” Scientific American, 2008: both legends are false; the wall shows “only... under a specific set of weather and lighting conditions,” and desert roads and runways turn out to be more conspicuous. Astronaut Jeffrey Hoffman, five shuttle flights: “I never saw the wall.”

What is true, and the textbook problem. It can be photographed from orbit: Leroy Chiao's 2004 ISS photos were the first confirmed ones, and Chiao himself “didn't see the wall, and wasn't sure if the picture showed it.” Radar images pick out sections easily. In 2003 Yang Liwei, China's first astronaut, said he couldn't see it; there was talk of rewriting school textbooks. In 2004 the European Space Agency published a satellite photo it said showed the wall; it later admitted the image was actually a river near Beijing.

The point. The claim is nearly three centuries old and has never needed to be true. It just needed to be repeated.
