Just to keep it straight ...
It's Trump's Secretary of Homeland Security who's allegedly having a barely concealed affair with her married aide who tried to fire a Coast Guard pilot for not turning their luxury jet around mid-flight to go back and get her blankie ...
Powerful stuff.
It's ironic to see a discipline care **so much** about unbiasedness (causal inference!) at the level of a single test but then have a research production system and culture that is basically a ferocious bias generation machine. This is not good.
So little discussion of Claude code on here. We are experiencing an unprecedented shock to how empirical research is done and it's going to primarily affect grad students
Amazing, thanks for sharing this!
CIA STORIES - SPOTLIGHTING THE WORLD FACT-BOOK AS WE BID A FOND FAREWELL February 4, 2026

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!

Call for Proposals: Data Collection for Replication+Novel Political Science Survey Experiments Alexander Coppock and Mary McGrath January 27, 2026 We invite proposals for a survey experiment replication+novel design competition. Se- lected replication+novel design survey experiments will be conducted on large samples of American respondents, quota sampled to match U.S. Census margins and filtered for quality and attention by the survey sample provider Rep Data (repdata.com). Each proposal consists of two parts: (1) a replication study of an existing, previously published survey experiment, and (2) a novel experimental design on a topic of the authors’ choosing. The replication studies and reanalyses of the existing studies will be combined into a meta-paper to be co-authored by all authors of accepted proposals along with the princi- pal investigators (Coppock and McGrath). As a condition for acceptance, authors commit to sharing the data and producing a write-up of the findings from their novel design for submission to a scholarly journal, and public posting of a working paper pre-publication.
🎺 Call for proposals 🎺
1️⃣ replicate an existing experiment
2️⃣ run a novel experiment
on repdata.com
3️⃣ coauthor with Mary McGrath and me to meta-analyze the replications and existing studies
4️⃣ publish your study

New study finds that emphasizing collective efficacy (people's ability to catalyze large-scale change) is very effective in catalyzing behavioural change.
As you can see from my pinned post, I'm a big fan of simple messages that can mobilize public support for climate action!
I still remember vividly reading this NYT headline in October 2024, sitting in a coffee shop in Boston, a fortnight before the presidential election

Tillykke, Kristian! ☺️🥳
Number of UK newspaper editorials arguing for more (blue) and less (red) climate action, 2011-2025. Some editorials also present a “balanced” view, which is categorised as advocating for neither “more” nor “less” climate action. These editorials are not represented in this chart.

If the figures we're getting out of Iran are in the right league, this weekend was, I think, one of the bloodiest state crackdowns of all time. People are talking 12,000-20,000 dead; for comparison Hungary in 1956 was about 2,500, Tiananmen - across country, in multiple cities - probably 1000+
The utterly shameless & widely covered "report" out today, claiming net zero will "cost" £9tn is based on:
* Assuming free fossil-fuel energy, free petrol cars, free gas boilers, free gas power plants etc
AND
* Including climate damages in the "cost" of net zero
I kid you not, it is that stupid
Distraught woman says ICE killed her wife in video after deadly Minneapolis shooting "They killed my wife," the distraught woman says, adding, "They shot her in the head." An ICE agent shot and killed a 37-year-old woman who was driving an SUV in Minneapolis on Wednesday. / Screenshot/@Breaking911
"They killed my wife. I don't know what to do," the woman says through sobs in the footage, with a damaged SUV visible in the distance behind her. "We stopped to videotape, and they shot her in the head," the woman cries. "We have a six-year-old at school," she says, almost unable to breathe, as a chaotic scene in which federal officers prevented at least one doctor who was on the scene from assisting the shot victim unfolds. "We're new here," the distraught woman says in despair.
You and your wife drop your 6-year-old off at school. You just moved here. You see ICE terrorizing your new neighbors. You film them, as is your legal right. Your wife complies with orders. She is then shot in the head. You still have to pick up your child later today.
This could be you.

New paper! @william-dinneen.bsky.social @guygrossman.bsky.social Yiqing Xu and I use GPT to code 91k articles from 174 polisci journals (2003–2023)and track research designs, transparency practices, and citations. How has the credibility revolution reshaped the discipline? doi.org/10.31235/osf...

(1/10) 🚨Preprint alert!🚨
In this article, I challenge claims of a generational rise of conservative men. In the media and recent academic publications, the so-called ‘youth gender gap’ has been interpreted as a generational phenomenon.

Sauron actually doesn't do much in the Third Age. He's awake for 2000 years, and for the first 1900 his accomplishments amount to "he made the forest scary." The Witch-King, the Balrog, Shelob, and Smaug are all out there making trouble, but he's just napping or something.
Do you teach #rstats? Do your students complain about how lame and old-fashioned dplyr is? Don't worry: I have the solution for you: github.com/hadley/genzp....
genzplyr is dplyr, but bussin fr fr no cap.

My quote from an Axios interview, stating that: People often think of climate change as a separate bucket at the end of a long row of other buckets of problems we're trying to fix that are wrong in the world," Hayhoe told Axios. This includes poverty, disease and access to clean water. "Climate change is not a separate bucket," Hayhoe said. "The reason we care about climate change is that it's the hole in every bucket."
If you take the time to read the whole Gates memo (which I did), the bulk of the content was mostly solid and encouraging. Really!
It was the FRAME that was off--very off, from the first line.
And when your framing is off, then how you make decisions and set priorities is off. THAT'S the problem.

Three schematic diagrams. The first illustrates selective publishing of internal resection, the second selective causal focus, and the third selective access and funding for researchers.
1. We ( @jbakcoleman.bsky.social, @cailinmeister.bsky.social, @jevinwest.bsky.social, and I) have a new preprint up on the arXiv.
There we explore how social media companies and other online information technology firms are able to manipulate scientific research about the effects of their products.
