Graph showing the proportion of clinical psychology studies that adopted four transparent research practices (preregistration and sharing of measurement instruments, data, and analysis scripts) at three time points (2012, 2018, 2024). The graph suggests adoption of these practices has increased but remains uncommon.

Graph showing the proportion of clinical psychology studies that adopted three transparent research practices (reporting guidelines and disclosure of conflicts of interest and funding) at three time points (2012, 2018, 2024). The graph suggests use of reporting guidelines has increased but remains uncommon. Conflict of interest disclosure statements have increased and are now quite common. Funding disclosure statements were relatively common across the three time points.

Has transparency improved in clinical psychology? New cross sectional study from us (Bianca Kotoulas, Justine Blackwell & me). Adoption of transparent research practices has increased between 2012, 2018, & 2024, but aside from coi and funding disclosures, they remain uncommon osf.io/preprints/ps...

We're thrilled to open registration for the Utrecht Replication Games. The event will be at the at the University of Utrecht on June 4th. Psych, public health, pol sci and econ studies will be reproduced!

Register here: www.surveymonkey.ca/r/Replicatio...

Excited and nervous for this event tomorrow. Come in person in Berlin, or join online!

I’m impressed.
A nice example of how to handle this with transparency and honesty. Carroll makes a strong case for accountability.

This thread makes clear that it’s reasonable to expect some explanation and soul-searching from those who were connected with Epstein.

Need a bit of happy news in your timeline? I haven’t read the full report yet, but this thread makes me happy.

Why are many academics still ok signing with Brockman (or his agency)? Many are oblivious to the Brockman-Epstein link (despite the 2019 articles above).

It’s still not widely known.

So let’s change that.

If you or someone you know is planning a popular book, don’t go with the Brockman agency.

How Jeffrey Epstein Bankrolled An Exclusive Intellectual Boys Club And Reaped The Benefits The Edge Foundation runs what has been called the “world’s smartest website” and held annual “billionaires’ dinners.” It was also financed by Jeffrey Epstein and gave him access to elite circles in sc...

Academics:
If you’re trying to make sense of how people you know knew Epstein, it’s book agent John Brockman. He’s savvy enough to lay low, but we should be talking about him.

Friends don’t let friends sign with Brockman.

How to Set Up and Run an Undergraduate Research Lab APS Fellow Julia Strand offers resources and recommendations to run a productive research lab.

Just out—a piece I wrote a piece for the APS Observer (@psychscience.bsky.social) in which I share recommendations and resources for running a research lab at a small, liberal arts college. I hope it helps others in the same boat! www.psychologicalscience.org/publications...

📅 Mark your calendars for #SIPS2027!
The 2027 SIPS conference, organized in collaboration with the Association for Interdisciplinary Meta-Research and Open Science @aimosinc.bsky.social, will be held in November at the University of Melbourne, Australia.

We are looking forward to seeing you there!

Yep. This angle shows that what Bovino said — and what Trump, Miller, and DHS wrote —are lies. They’ve again murdered someone trying to help neighbors, and are again slandering that person. Not to cover anything up, but to project their power and impunity. To suppress dissent, and to set an example.

I don’t think it’s a complete coincidence that, yesterday, so many of us around the world were in awe of what Minneapolis was doing, and, today, the government brutally murdered one of those courageous people, just to show us they could. They think they’ll scare us into submission. They’re wrong.

Rethinking psychological measurement: Validity potential versus realised validity We propose a concept of validity with a novel feature that we argue can facilitate improved measurement validation practices in the psychological scie…

Thrilled to share our new paper introducing “validity potential” versus “realised validity” as a key distinction for psychological measurement, with @davidmkaplanx.bsky.social, Alexander Gillett, @suttonprofessor.bsky.social, and @robert-m-ross.bsky.social www.sciencedirect.com/science/arti...

That’s “below-zero temperatures” in Fahrenheit. -22 in degrees Celsius. Minneapolis, you’re amazing.

RegCheck RegCheck is an AI tool to compare preregistrations with papers instantly.

Comparing registrations to published papers is essential to research integrity - and almost no one does it routinely because it's slow, messy, and time-demanding.

RegCheck was built to help make this process easier.

Today, we launch RegCheck V2.

Medical breakthroughs in 2025 ... and a happy new year.

New post!

There was a lot of innovation in medicine and biomedical research this year, and I've tried to summarize the biggest ones in this blogpost.

Medical breakthroughs in 2025. Plus a serious note at the end.

What should psychology journals do about this? What’s a reasonable policy/standard to apply to research using online data collection methods?

Sydney, and Australia, are still grieving the attack on our Jewish community.
Since moving to Australia, one of my favorite things about it is that I feel so safe here. It’s devastating to know that that feeling has been taken away for our Jewish friends and neighbors. I’m so sorry.

Literally the topic of our hackathon last week 😂
(Specifically in the context of meta-analysis.)

We all need something uplifting right now, especially in Sydney. Here is “an absolute bloody legend” (according to his owner, but I agree):

Congratulations to @bethclarke.bsky.social on her PhD graduation!! It’s been amazing watching you become the incredible scholar that you are, thanks for letting me come along for the ride!
You’re the best! 🎉🥂🌟

Preparing this talk gave me an opportunity to reflect on what lessons I've learned from psychology's replication crisis and credibility revolution, and what advice I would have for other fields. We've come a long way!

Fig. 3. Effects of the intervention. In (a) are shown effects 7 months after the intervention; in (b) are shown interaction effects 7 months after the intervention. Models show the effects of the intervention on expressive-language skills in the grade 1 posttest, with an interaction between expressive-language skills in the pretest and after the intervention. Standardized coefficients (with 95% confidence intervals) are shown, except for the intervention dummy variable and the interaction where y-standardized values are indicated. Rectangles and circles contain observed variables and latent variables, respectively. Solid arrows point to significant regression or factor loadings (arrows from latent variables to their observed indicators); the arrow with dotted lines shows nonsignificant regression. The interaction (Fig. 3b) is illustrated by the arrow from the black circle to expressive language in the posttest. **p < .01.

Fig. 4. Long-term effects of the intervention on expressive-language skills. Model showing the effect of the intervention on expressive-language skills in the grade 4 posttest. Standardized coefficients (with 95% CIs) are shown, except for the intervention dummy variable where y-standardized values (equal to Cohen’s d) are indicated. Rectangles and circles contain observed variables and latent variables, respectively. Solid arrows point to significant regression or factor loadings (arrows from latent variables to their observed indicators); arrows with dotted lines show nonsignificant regression. **p < .01.
