Do you use logistic regression? If so, you’ll want to read the thread below. ⚠️ Warning: Memes, charts, #rstats, and practical advice ahead.

Hi folks! I'm looking for information (or strong opinions) on unipolar vs bipolar psychometric items. E.g. asking in one item 'sad --- happy' vs having 2 items, 'not sad --- sad' and 'not happy --- happy'. Can be for affect, personality, symptoms, etc. Thanks!

J’enseigne le cours d’introduction à l’économie de L1 à TSE. On ne fait pas de math dans ce cours. En débutant avec les dilemmes sociaux (théorie des jeux), puis en montrant comment le pouvoir de marché (monopole, oligopole) rend le marché inefficace, 1/4

Pour avoir ce débat, il faudrait s'entendre sur l'objectif d'une formation en économie. A mon avis, ce n'est ni de former des militants ni de futurs chercheurs. C'est d'apprendre à penser comme un économiste. Le rôle de l'économiste est de rappeler: 1⃣ Qu'il y a toujours une

42% of private school pupils in England get extra time in exams because of ADHD, dyslexia, or other diagnoses. FT’s article focuses on the difference vs state schools but their numbers are also crazy high. This is a serious cultural defect, and not only in the UK.

Prediction markets are really, really well calibrated.

It has also improved my writing a lot. The ability to instantly listen to drafts (of articles, chapters, blog posts, etc.) spoken by another "human" voice means I am much better at identifying errors, clunky phrasing, etc., than I used to be.

Just stumbled on this tool called Publish or Perish that allows you to save and export your Google Scholar search terms and search results (at least the first 1000). Could be a great facilitator of the reproducibility of systematic reviews! harzing.com/resources/publ…

Personal highlights from Claude's snarky AI comedy set.

Its a good question; why remake songs & movies, but not books?

NYT is softening every edge in the framing but this article is a bombshell Conclusive evidence that environmental scientists have been willing to use the ESA to knowingly invent "conservation species" and then (after passage in 1970) using the newly created NEPA to litigate

No. If you are a researcher, your primary goal should be research. Your research should absolutely involve informed consent but beyond that you are under no obligation to use your research to play savior. It's great if it has positive side-benefits, but that does not need to be

Worth reading this thread, whatever your priors on the importance of gene—many people fail to understand this. High heritability of Y *does* *not* *imply* that genes directly cause Y. Heritability is not a well-named concept — it does not mean what most people think it means.

It seems we are again discussing the idea that general intelligence doesn't predict real-world outcomes above some threshold, such as 120 or 100 on the IQ scale. We found virtually no evidence of this in four separate cohort studies across many different outcomes, e.g. income:

Popper on electing tyrants (from The Open Society)

Guys, this story gets weirder and weirder. 1. Robert Nobel dies 2. Euro newspapers mistakenly think Alfred died and printed mean obituaries 3. Alfred reads his own obituary, has change of heart, donates money to science?????

If Biden appointed Ibram X. Kendi the antiracism czar, and Kendi announced on Twitter that he is allowed to unilaterally defund any program he deems racist with no input from Congress, and his team tried to access the Pentagon, then yes, I think Pentagon staffers would have a

It's a privilege to engage with an expert like Joe Henrich on a question as important and foundational as the role of culture in perception. But Dorsa Amir and I think this thread gets several key details wrong, both bigger-picture and finer-grained. Here's how (🧵):

Big kudos to this team for doing the work of uncovering what looks like large-scale research malpractice. Some highlights in this thread.
