Wow. For the WFAs "2,213 papers were submitted, which is a record for an in-person conference, and we were only able to accommodate 156 papers on the program for an acceptance rate of 7%." That's a lot of papers!

This looks super cool

We have a new paper in JAMA Internal Medicine! Patient race is widely used in medical algorithms...but it's unclear how patients feel about this. We conduct the first nationally-representative YouGov survey to find out, producing four findings with practical clinical implications. 1/

My manuscript "The Economics of Noncompete Clauses" is now out in the Journal of Economic Perspectives. Few topics have garnered more debate and policy attention over the last few years. This article brings us up to speed on the debate and the current answers. pubs.aeaweb.org/doi/pdfplus/...

The CIA just stopped publishing their World Factbook and took every page, including the archived copies of previous versions! This sucks. It was public domain, so I recovered the 2020 edition (the last one published as a zip file) and shared it to GitHub simonwillison.net/2026/Feb/5/t...

dplyr 1.2.0 is out now and we are SO excited! - `filter_out()` for dropping rows - `recode_values()`, `replace_values()`, and `replace_when()` that join `case_when()` as a complete family of recoding/replacing tools These are huge quality of life wins for #rstats! tidyverse.org/blog/2026/02...

I just came here to say that I'm 10 years out from my PhD and I'm "tenured" and the imposter syndrome is still strong. Maybe not for everything but for a number of aspects of my job.

Most unusual SI/methods write-up I've seen in a while: Digging in Utah scrapbooks for hair samples to document historic lead levels. Remarkable findings, note the log-scaled y-axis.

An unfortunate thing is that if you do a really bad job teaching, students will frequently assume that you’re clever and they didn’t understand it. Same thing for poorly written papers

People have been using birds to send messages for centuries. Given what, say, salmons and eels are able to do, I wonder why nobody has thought of using fish... Is this because they are unreliable as messengers? That seems like an easy problem to solve! Just use error-correcting cod

A surprising amount of AI fear mongering can be boiled down to this simple trope. See also: PROGRAMMER: “I gave an LLM access to launch the nukes with no oversight” LLM: “I launched the nukes” PROGRAMMER: “Oh no how could you have done this?!? AI is so unsafe”

A lot of criticisms of chatbots seem to imply that it is incredibly harmful to your knowledge and ability to think to use a human research assistant

The better LLMs get, the more data scientists are going to find out the truth.

#rstats I've been testing out `arf`, a new R console written in Rust. Early days, but a v. smooth experience so far. Much simpler to install and link from VS Code than radian, for example, with better features too. github.com/eitsupi/arf

Some opinions about the Anthropic paper which I haven’t read: 1. It confirms all my priors 2. My interlocutors now look foolish Probably don’t need to read it I guess

Quick primer on what is www.moltbook.com, the thing driving people crazy on the internet

Ok, so a brief but serious explanation of why I find the whole www.moltbook.com thing silly: So what's happening, exactly? Moltbook is an API service that can be called by LLMs. The Agents who engage with it are told to add skills.md to their context window (e.g. they are given instructions):

A new study from Anthropic finds that gains in coding efficiency when relying on AI assistance did did not meet statistical significance; AI use noticeably degraded programmers’ understanding of what they were doing. Incredible.

This is just sloppy writing jesus christ

Ross Douthat and other prominent posters are kinda losing it on twitter about this and all I can think of the 1896 short film Train Pulling Into the Station which had this reaction

Very interesting research paper that shows that using AI with programming can significantly reduce mastery over topics. Perhaps unsurprising, but the lack of significant speed gains in this exercise are remarkable www.anthropic.com/research/AI-...
