I would just appreciate it if people who value scientific rigor could apply a modicum of skepticism to headlines like “meta is hiding causal evidence.” I’m recalling the whistleblower thing from 2021 when it turned out that the hidden finding about body image was probably selection bias

After 5 years of data collection, our WARN-D machine learning competition to forecast depression onset is now LIVE! We hope many of you will participate—we have incredibly rich data. If you share a single thing of my lab this year, please make it this competition. eiko-fried.com/warn-d-machi...

Pleased to share for those using #rstats for analyzing #dyadic data, that we released a major update of dySEM on CRAN (now ver. 1.4.1) *just* before the winter break. New functionality for scripting/outputting dyadic SEMs, along with (much) more test coverage! 🧵 cran.r-project.org/web/packages...

It’s SUPER rare to have the opportunity to meet face to face with someone from the internet when you have a disagreement…but @alexip718.com and I did it! And it was a great discussion. At the end of the day, there’s not a handbook for how to face fascism in 2026. We are all doing our best ✊🏼❤️

First off, Stranger Things had a good ending. It was messy but it fit with the show and was a fun ride. If you expected a masterpiece then you weren’t paying attention 😂 Second, the best ending to a show was Schitt’s Creek

Just to clarify: once again, this study has only an observational design and reverse causality or third variables are perfectly possible. We simply don't know if social media "harmed" any participant

Great set of studies showing that 5-7 year old children already show a tendency to go against evidence and agree with their ingroup, and largely do so to signal affiliation (loyalty? gain status? avoid rejection?) - fascinating work on early peer influence mechanisms!

I used “circle back” in an email today and I now I feel gross

I wrote about Nucleus Genomics' "Have your best baby" ad campaign and Kris Jenner's "best version of myself" facelift, the parallels between embryo selection and cosmetic surgery, and competing definitions of "eugenics" kathrynpaigeharden.substack.com/p/have-your-...

and that’s enough internet for today

Do I have any Canadian authors following me? I have a tax question about when to declare the income earned from royalties. Canucks only though.

As usual, a bunch of of these predictions are exactly or essentially come true, with a few bananas that didn’t pan out. Happy new year!

12 months ago, I had no idea who Colette was. What she and her team have accomplished in the last year — to stand up and fight for American science — is truly phenomenal. Science has made all of our lives better. Stand up for it. Support what she and her team are doing — however you can.

Happy New Year everyone!

Here are my top 6 reads from 2025! I read 34 books this year, mostly novels. Complete list from Goodreads in the next post.

Tag yourself, friends! Colette needs us for something!

ALRIGHT! WHERE ARE MY CANADIAN SCIENTISTS?!

I wanted to answer a few common questions about our @standupforscience.bsky.social petitions! People get the heebeejeebee's about the fact that we collect data, I would like to address concerns. 1. We do NOT sell *or* share our data. Period. EVER. 2. We collect addresses to use for activism...

Canada re: the U.S.

After another annual re-watch, I’ve concluded that “Spirited” is most definitely my favourite holiday movie and I’m not sorry one bit 🎄

Maybe this will replace panic over kids using too much social media

The 2025 Headline of the Year Nominees 🧵

Honored to be appointed by @governor.ca.gov to work towards a safer and smarter internet for all of California’s children. A massive thanks to the Governor and First Partner's offices for making child online safety and countering image-based abuse a priority for the year ahead.

Whoo boy I watched the leaked CEGOT segment from 60 minutes. That was A Lot.

I'm going to do a WRITING SPRINT! Starts in 16 minutes at the top of the hour. 1 hour of focused work on any task. You can jump in if you want!

I was expecting a quaint story about an old lady who liked nature so much she worked in the park till she died. This absolute lion of a human being *started* at the park service at age 84, after an entire lifetime of impressive community and social justice work. <we’re_not_worthy.gif>

McGill is hiring scholars from outside Canada! The Canada Impact+ Research Chairs (Impact+) Program is designed to attract world-leading researchers whose work addresses critical national and global challenges. Review of applications begins 1/16/26. www.mcgill.ca/research/res...

For any non-Canadian researchers out there, our government recently pumped a ton of cash to try and attract international researchers to Canada. So if you're looking for a change, timing could be good! Our university is hiring 30 international ppl, but you'll see similar things all over Canada

This thread, up and down, is a constant theme for me. Wrote a whole article about it. Please let master’s students do a project that matches their level of training 🙏

Hey out there to all my mid-to-late career colleagues, do you want to come work at Carleton? Our government is pushing hard to recruit international talent right now. Posting below, and a few details about how I love where I work 1/7

Our university press team asked me a few questions in regards to the new chair on Mental Health & Data Science. I sketch a bit of a vision on the importance of transdisciplinary work, and some obstacles to overcome. www.universiteitleiden.nl/en/news/2025...

I've used Lavaan almost every (work)day for 15 years, but this open source labour of love has never received proper institutional support. I'm delighted to be a small part of an 1.5M OpenScienceNL award, led by Jorgensen, to completely revamp and futureproof Lavaan www.openscience.nl/en/news/45-p...

You remember that Nature Aging paper about how multilingualism protects against accelerated aging? Well…

Ha! I got a shout out 😊 This post brought to you by: Relentless nostalgia for postdoctoral fellowship years and by Full professors with too much time on their hands

Children Helping Science is a platform that lets researchers conduct studies online with kids. Incredibly important resource for psychological science. An anonymous donor is matching contributions up to 100K through the end of the year - please consider supporting this high-value system if you can!

That’s a good cheese sauce. Departmental potluck here I come 🧀
