Team Canada is playing very unfairly. 30% extra tariffs on Canada if they win the hockey game. Thank you for your attention to this matter.

Open up your wallets, funders! I want to test a small interaction and will need the gdp of a small country to get enough participants. 💷 📈

🚨Thrilled to share our new @nber.org WP. Research and policy often assume teacher effectiveness is essentially fixed. We revisit this question by studying what happens when high-performing teachers are incentivized to transfer to struggling schools. 🧵 nber.org/papers/w34845

Being interdisciplinary mostly means everyone agrees your work is interesting but not for their journal.

I have a new paper. We look at ~all stats articles in political science post-2010 & show that 94% have abstracts that claim to reject a null. Only 2% present only null results. This is hard to explain unless the research process has a filter that only lets rejections through.

All of Canada when Bad Bunny yelled CANADAAAA

“would you review this manuscript” sorry, i’m de-centering men

Where in the world does typical teacher professional development address educational inequity? Out now w/ Nils Kirsten and Jan-Eric Gustafsson! And since Bluesky seems to like econometrics, the #OA study uses a within-student-between-subject approach :) link.springer.com/article/10.1...

Come and work with us at the University of Gothenburg! Our large interdisciplinary school segregation project is hiring 3 PhDs--I will co-supervise project 1. We are looking at determinants of teacher sorting using Swedish register data. Being passionate about quantitative methods is a big plus :)

my wrath for Microsoft teams knows no bounds

The beauty of academia? Total freedom to pick which 7 days you work each week.

This is a personal attack.

"But unlike No Child Left Behind, Mississippi also measures how much students progress toward proficiency. Schools get credit if students show improvement — and double credit for the improvement of students in the bottom 25 percent."

after 10 years working in academia, starting 2026 by unpacking my office properly for the first time because... *tenure* 😭 (or as we say in Scandinavia, a permanent contract!)

I tried a version of this—muting the color down about 75%, rather than going entirely black & white— and Julia Angwin is on to something. www.nytimes.com/2025/12/25/o...

I really can't emphasize this feeling enough

I’m convinced that this map is reflecting reality perfectly.

Grading and googling hallucinated citations, as one does nowadays, and now that LLMs have been around for a while, I've discovered new horrors: hallucinated journals are now appearing in Google Scholar with dozens of citations bc so many people are citing these fake things

I have done this a few times... In our profession we got so much rejection and even R&Rs may focus on the negatives. Telling someone you like their paper is refreshing for the person and you too!

How to know your kids have an academic for a mom: “we’re going to the postdoc!” (The doctor)

One of the most upsetting articles I've read in a long time www.theargumentmag.com/p/when-grade... UCSD report senate.ucsd.edu/media/740347... We are failing a generation of kids.

Elsevier has a 38% profit margin, and the other journal publishers aren't far behind.

Yep. People are talking about the latest Frankenstein film. But Mary Shelley was also an abolitionist, and she and husband Percy abstained from sugar because it was produced with the the labor of enslaved people. "In every pound of sugar used… consuming two ounces of human flesh," - William Fox

I'm in Rome, a city I'm given to understand has some history (Carnap once visited). I look forward to trying out their world famous pineapple pizza delicacy.

For each additional moral–emotional word in a social media post, the number of shares increases 13% Our new meta-analysis finds robust evidence of moral contagion (N=4,821,006) The moral contagion effect is even stronger in larger, pre-registered studies (17%). academic.oup.com/pnasnexus/ar...

We could easily be made to believe that nothing happened, and yet we have changed as a house that a guest has entered changes. We can't say who has come, perhaps we will never know, but many signs indicate that the future enters us in this way in order to be transformed in us long before it happens.

if at first you don’t succeed, try try again! The next 4 years are starting to look a little hectic… www.vr.se/soka-finansi...

the hardest working words in social science are “to what extent”

Make an effect size prediction! @jamiecummins.bsky.social and I are replicating Balcetis & Dunning's (2010) "chocolate is more desirable than poop" (Cohen's d = 4.52) Let us known in the replies what effect size you think we'll find. Details of the study in the thread below.

I brought back in-class exams because of AI. Now I need AI to read their handwriting.

It seems unbelievable that some journals still keep digitized versions of journal articles from over a hundred years ago *paywalled*!

currently in the “is this study amazing or so bad I should jump off a bridge” phase of manuscript editing

man this is a cool study
