New paper out now 🥳 When psychologists discuss generalisability, they often refer to vague notions of representativeness. We provide an accessible intro to the total survey error framework as a tool to reason about this more rigorously. w @taymalsalti.bsky.social @ruben.the100.ci >

Sobering: initial trials with huge effect, large follow-up trial showing no evidence for an effect. But practice is already locked in and criticism is defused by pointing to random effects meta-analyses which are necessarily dominated by the initial trials. polypharmacy.substack.com/p/we-should-...

0 shots on goal, 19 fouls, 2 touches in the opponent's box, 3 yellow cards. dismal stuff tbh

Love the collective hate for this half time show here

Amazing how far cat technology has come. Five years ago we would have been left to guess

Today we launch the first stable release of RegCheck: v1.0.0. RegCheck makes it easier and quicker to compare study registrations to published papers for consistency - something we know is important in principle, but rarely done in practice. A 🧵 on what's new: regcheck.app

Bringing one of the best tweets of all time over to Bluesky in honour of the Three Lions QF victory

At the risk of being a killjoy... the comments + quotes on this seem to interpret it to mean the study found no sex differences in the brain and that isn't really what it says. The paper is way more interesting than that. So I read it and made a thread as I went: 🧵 1/n

We also need better reporting. Only 35% of studies provided enough info to know the operationalization, and 56% reported no information at all. Reporting recommendations:

New commentary out in JCCP! In which I try to solve the problem of incomparable effect size estimates in clinical trials by recommending a standard, one-size-fits-most way to compute the standardized mean difference (SMD; e.g., Cohen’s d) in psychology trials. doi.org/10.1037/ccp0...

Excited to share a paper recently accepted at Nature Mental Health! 😄 For decades, we've assumed that covariance among psychopathology informs comorbidity. What if we’ve been wrong?

This sounds bad, but what if Meta sends a big city lawyer and she's from the Wyoming town and hasn't been back since high school and gets there just in time for Christmas? It really makes you think.

Honestly, the ref was fine and Egypt screwed that game up on their own.

‘Polarization’ has become the master concept for diagnosing our current democratic crisis. But this is not polarization. It is the radicalization of the political right. By misdiagnosing it, we risk becoming complicit in the crisis. 🧵 Just out in Perspectives on Politics doi.org/10.1017/S153...

The greatest Mexico v England tweets you will ever read. 😂 As you were.

SEP finally covers #psychotherapy (what counts as one, how it should be evaluated, relation to #wellbeing and #mentalhealth, nature of its expertise). Important work by @plutynski.bsky.social and Megan Delehanty #philsky #ethics #philmed

Had to read this one to figure out whether it's as click-bait-y as the title. As somebody who has written a lot about causal inference with observational data, I'm quite conflicted about it.> asteriskmag.substack.com/p/the-case-a...

1/ @sadcatlab.bsky.social research "in press" at Journal of Consulting and Clinical Psychology. In 274 adults with 7 weekly measurements, we find that cognitive change in CBT predicts subsequent symptom change, controlling for time-invariant confounds + linear trends osf.io/preprints/ps...

Someone should let them know it would be more effective with adjunct psychotherapy.

When I was like 17 I asked a cousin who was quite into it about WoW and his face went very serious & he grabbed me by the shoulders & said "look I know you and I know your personality so never ever get into this thing because you will ruin your life" and somehow it worked and I have never played WoW

Exciting day. My set-theoretic reconceptualization of the DSM (w/ MDD, GAD, and PTSD as empirical examples) is out today in JPCS, along with four invited commentaries and my response. I'm biased, but I recommend all six papers. I was really jazzed by all four commentaries. 1/25

Most of the statistical tests you learned in stats class — t-test, ANOVA, correlation — are actually special cases of a single thing: linear regression. Ch 7 of Experimentology argues that thinking in models, not tests, is more flexible and a better foundation for theory. 🧵 experimentology.io

I've interviewed quite a few PhD student parents in my research. And while it's not universal, a pattern I've seen is--if dad is the student, mom drops out of the workforce or works part-time; if mom is the student, dad is the primary earner, so mom fits school around primary responsibility for care

Obesity rates in Pakistan have tripled in the last 20 years. In the 20th century, obesity was a health problem that mostly affected today’s rich countries.

New review, forthcoming in the Annual Review of Developmental Psychology: "From Seconds to Seasons and Days to Decades: Timescales in Development." Let me walk you through some key points. 👇 BC its a review, these are based on many others' work. osf.io/preprints/ps... 1/

“I have done all of the things that one is supposed to do to earn a tenure-track position. And I have done approximately 85% of them by typing prompts into a large language model and then moderately editing the output.” 🤣🤣🤣 brilliant 👌🏽 open.substack.com/pub/inprepar...

Yes when I was first doing work on the replication crisis around 2012-ish this was one of the most striking things to discover by learning the history ... it was déjà vu all over again

Europe is Burning. But we can cool it down. Our cities are currently built to trap heat. But we can change it. Here are 7 actionable things cities can do today to cool down:

Apparently posteriors are sensitive to priors!* Specifying informative priors is a sign of a maturing field! I hope our new paper nudges psychology toward complex Bayesian models — based in formalized theories — and away from "default" priors that lack theoretical or practical grounding.

Be careful out there

Dr. Odgers is one of the best public voices on this topic! Listen to her description of the data debunking the narratives around social media harm. I really like the point about adult caregiver mental health being a much better public health target than social media

1. Do antidepressants really need weeks to "kick in"? A paper correctly dispelled this myth. Unfortunately, they replaced it with other problematic claims, igoring principles of RCTs. My letter to the editor was rejected, so I posted it on PubPeer and summarize it below pubpeer.com/publications...

This is the kind of almost magic-like payoff we get from decades of basic and applied research by thousands of scientists across the globe. This is why we do it.

Imagine if there was a hurricane-force blizzard, and we just showed pictures of kids playing in the snow

very cool that I still can find new interesting people to follow here basically every day.

I'm not going to out anyone, but I know from private conversations that many of us are using AI, especially Claude. I think people avoid acknowledging it due to the stridency of the anti-AI folks. One that thing that confuses me though is the focus on writing. No one I know is using AI for writing.
