Nature tidbits [15 Jan 2026]

The cover of the 15 Jan issue of Nature is a blurry reconstitution of snapshots from the James Webb Space Telescope, which contributed to uncover these new astronomical objects, deemed to be young supermassive black holes. A notion I only came across recently, during a pre-defence lunch near the Paris Observatory.

Apart from that astronomical advance, Nature puts its focus on the 25th anniversary of Wikipedia. With a tribune bemoaning the insufficient investment of academics in the platform (with mentions of hypocrisy and betrayal). Which sounds rather unfair, since it requires an additional levy on research time, even though I did contribute to a few entries. And recognise the worth of most scientifics pages, as well as the parasitism by LLMs. And an interview of of Jimmy Wales’ about his Wikipedia memoir, Seven Rules of Trust. Kudos to his vision! He sounds rather optimistic about the chances of Wikipedia surviving the tsunAImi, but only if the users keep resorting (and indeed contributing) to the platform rather than accepting the LLM production at fa(r)ce value!

Other entries on

  • LLMs suffering (!) from “anxiety, trauma, shame and post-traumatic stress disorder”, although the arXiv reporting the experiment is criticized by others for anthropomorphising the machines. The danger is more in them inducing real trauma in vulnerable (human) users!
  • LLMs exhibiting aggressive behaviour (if trained accordingly)
  • the oldest evidence on human controlled fires using pyrite (in SE England), 400,000 years ago
  • the rise of academics being harassed (and not only in the US) and six recommendations for protecting our digital security (mentioning organisations such as Scholars at Risk Europe, Expert Voices Together, and Faculty First Responders)
  • a “Where I work” picture of a food scientist at the National Autonomous University of Mexico flipping a tortilla, with fermented ingredients to improve health and combat malnutrition in poor communities

post-Bayes workshop at UCL [15 & 16 May 2025]

University College London (UCL) is organising a workshop on post-Bayes inference  and asked to post the announcement (despite my feeling that we have not entered the post-Bayes era!). So here it is:

Over the course of two days, they will host eight invited talks from leaders across the post-Bayesian landscape, spanning from PAC Bayes and generalised Bayes to predictive resampling and martingale posteriors. Alongside these, they will host six contributed talks, and a poster session to ignite discussion and innovation in our growing community. The workshop will complement the post-Bayesian seminar series.

Registration is now open, and they are actively accepting talk and poster submissions! (Deadline for submissions: April 11th, 2025.) Travel support for early career researchers will be available and announced closer to the date. See the website for more information. The workshop will take place in Bentham House, UCL, London.

[As a personal aside, we just learned that our proposal for an approximate(ly) Bayes workshop supported by ICMS (Edinburgh) and set on the magical Isle of Skye had been accepted! To be held in Spring 2026!]

the flawed genius of William Playfair [book review]

David Bellhouse has written a new book on the history of statistics, focussing on William Playfair this time (following his fantastic book on Abraham de Moivre). The Flawed Genius of William Playfair (The Story of the Father of Statistical Graphics) got published a few months ago by the University of Toronto Press.

“[Playfair] was an ideas man whose ideas often did not come to fruition; or, when they did, they withered or exploded.” [p.121]

The impressions I retained from reading this detailed account of a perfect unknown (for me) are of a rather unpleasant, unappealing, unsuccessful, fame-seeking, inefficient, short-sighted, self-aggrandising,  bigoted, dishonest, man, running from debtors for most of his life, with jail episodes for bankruptcy, while trying to make a living from all sorts of doomed enterprises, short-lived blackmailing attempts, and mediocre books that did not sell to many. Similar to David Bellhouse’s colleague earlier wondering at the appeal of exposing such a rogue character, I am left with this lingering interrogation after finishing the book

“[Richard] Price liked what Playfair had written. He found [in 1786] Playfair to be “agreeable” and “useful”.” [p.64]

Not that I did not enjoy reading it!, as it gives a most interesting of the era between the 18th and the 19th Centuries, in particular in its detailed narration of the first months of the French Revolution of 1789, and of the impact of the Industrial Revolution on economics and politics as the birth of capitalism. The book abounds in crossing lots of historical characters, like Richard Price (Bayes’s friend who published his most famous paper), Adam Smith (whose book Playfair reprinted with poor additions), Edward Gibbons (whose book along with Smith’s inspired the title of his Inquiry Into the Permanent Causes of the Decline and Fall of Powerful and Wealthy Nations), Thomas Malthus (competing for an annotated edition of Smith’s book), not to mention the political class of Britain at the time. David Bellhouse’s book demonstrates academic and historical excellence, constantly being very detailed, with a wealth of references, documents, and definite support for or against the rumours that accompany the life and deeds of Playfair. (Frankly, rarely a name has been that inappropriate!) This includes for instance the pictures pointing out to his first (?) forged signature [p.140] and the evacuation of the myth of Playfair as a spy for the British Crown—which the Wikipedia page happily reproduces, pointing out the need for an in-depth revision of said page. Similarly, the book delivered a convincing discussion of arguments for and mostly against Playfair “being the key player in the British operation to forge [French] assignats” towards destroying its economy. A lot of the book is touching upon the then novel issue of paper money, which Playfair only and negatively considered through his own (and catastrophic) experiences. At times, the book is almost too scholarly as it makes reading less fluid than was the case his Abraham de Moivre for instance. (And obviously less than in the contemporary Jonathan Strange & Mr. Norrel!)

It may be that my very relative lack of enthusiasm stems from the realisation that the story of Playfair is overall rather little connected with statistical inference, if not with descriptive statistics (albeit with a complete disregard for the quality and sources of his data), as when  publishing a Statistical Breviary on descriptive statistics for a series of countries (and surprisingly sold on Amazon!).  Or Statistical Account of the United States of America. And of course for his innovative graphical representations like the one represented on the cover of the book or the pie chart. I feel that the book is much more engaged in Playfair’s contributions to the then nascent science of economics, as for instant about the shallow and mostly misguided views of his’ on banking and running the economy, while conducting his personal finance and investments so disastrously that it negatively advertised against confidence in such views.

On a very personal level, I noticed that some graphs were provided by my friend and statistics historian Stephen Stigler [who also wrote a review of the book] while an analysis of the poor French involved in a coding scam of Playfair about Napoléon’s escape from Elba was by Christian Genest (whom I first met at a statistics conference dinner on the Lac de Neufchâtel in 1986).
