New blogpost: what to do about Discussion sections of papers, which are often an excuse for overhyped and p-hacked conclusions.

The @DataColada team has been sued by Francesca Gino for exposing the fraudulent data underlying four of her papers (she claims defamation). The legal defense could get expensive. Please join us in providing financial support for their defense.

When someone who grew up with the Pipes screensaver starts designing real world infrastructure

@alfora @futurebird @MostlyHarmless My favourite Excel “feature” is that biologists ended up having to rename some genes because Excel “autocorrects” them, leading to detectable errors in over 30% of a sample of published journal papers:

“What is not funny though is having genomics spreadsheets suffer from auto-conversion of gene names like SEPT8, DEC1 and MARCH3 into dates, a problem first characterised in 2004. A 2016 article on this topic led the Human Gene Name Consortium to change many of these gene names to be less susceptible to autocorrect. Despite this, our work here shows that gene name autocorrect errors continue to accumulate in supplementary genomics spreadsheet files at a rapid pace.” — https://journals.plos.org/ploscompbiol/article?id=10.1371/journal.pcbi.1008984

How big problem it is that cross-validation (CV) is biased? I briefly discuss some points on this.

0. Unbiasedness has a special role in statistics, and too often there are dichotomous comments that something is not valid or is inferior because it's not unbiased. However, often the non-zero bias is negligible, and by modifying the estimator we may even increase bias but reduce the variance a lot, providing an overall improved performance.

Pólya’s conjecture is the usual example of a statement that’s true for many cases, but breaks down for some large value of n. In that example, n=906150257. However, I think I have a new favourite: gcd(n^17 + 9, (n+1)^17 + 9) = 1 for all n < 8424432925592889329288197322308900672459420460792433 (More counterexamples at https://oeis.org/A010034)

Que c'est navrant, on peut mettre des milliards dans l'IA, le quantique ou le spatial, mais on est incapables de recruter des profs en universités. Il faudra expliquer à nos têtes pensantes que les sciences et les techniques n'évoluent pas toutes seules dans l'éther du progrès : il faut des gens.

Sur Reddit, fascinante explication par la linguistique de l'usage immodéré des points de suspension par les plus âgé•es... et de celui du point d'exclamation ainsi que des smileys par les plus jeunes : https://www.reddit.com/r/PasDeQuestionIdiote/comments/15hqznj/pourquoi_estce_que_les_générations_de_nos_parents/juqw6ru
Désamorce complètement les moqueries adressées aux boomers. Et je sais enfin pourquoi j'utilise beaucoup trop de points d'exclamation dans mes échanges écrits, notamment sur ce réseau (tout en me sentant encore un peu jeune pour une fois, aussi).

@yoalor Tu veux t'abonner au flux rss d'un compte ? Si tu utilises masto sur un navigateur, clique sur le profil du compte, puis sur messages et réponses pour avoir tous ses pouets. Tu copies l'adresse web dans la barre d'adresse, tu la colles dans ton lecteur de flux ("s'abonner") en rajoutant à la fin .rss et c'est bon. Tu peux faire la même chose si tu affiches une recherche de hashtag sur ton navigateur, tu récupères l'adresse et tu rajoutes .rss.
Un exemple chez moi: https://mamot.fr/tags/climat.rss

Can we please stop saying my article is published in X if it's not open access. The correct phrasing is "My article is being held for ransom by X" or "We have, at great expense, hidden our article in X".
