Be aware of a bug on PsyArXiv @cos.io Triple check your preprint before submition. If it fails moderation you'll have to submit again from scratch. Updating files doesn't work rn. Mine failed as I forgot my email address on the front page, not great cause I really need to keep the original link...

The Robust Bayesian Meta-Analysis package got updated with additional vignettes explaining how to perform Bayesian model-averaged publication bias-adjusted - multilevel meta-analysis (cran.r-project.org/web/packages...) - multilevel meta-regression (cran.r-project.org/web/packages...)

It's been a week, but we left inspired after #PSE8 in Leiden. Thanks to all who participated in our mentor-mentee lunch! Hopefully you all had interesting conversations, and made new connections. ECR and want to see more of PYMS? Sign up for the mailing list: tinyurl.com/3mkn6f2a

Now that the #rstats pipe wars have flared up again, it's useful to remember what the pipe (base or magrittr) was designed for, and what it was never meant to do. 🧵 1 / 7

Does anyone have experience with CADIMA for screening articles? www.cadima.info I’d be interested in hearing thoughts, especially if you can compare it to rayyan #evidencesynthesis #systematicreview

Nice succinct pre-print from a stellar cast: "The state and status of theory in psychological science" osf.io/preprints/ps...

Call for Submissions for the Theory Methods Conference 2026, September 30-October 2! theorymethodssociety.org/conference.h... We invite you to: 1) Submit your proposal: edu.nl/mj9x6 2) Invite your colleagues/lab/(PhD) students, and encourage them to submit 3) Share this post

What's next? Let's try to unify the field a bit more. We're already taking a step into the future with the CO-IND (Cognition and Intellectual Disability) project. 37 groups in 23 countries using the same basic research protocol. Lots of opportunities ahead. coind-project.github.io

First study from my PhD project is now published. It has been overwhelming, but extremely insightful! 👇🏻

New paper, on a worrying trend in meta-science: the practice of anonymising datasets on, e.g., published articles. We argue that this is at odds with norms established in research synthesis, explore arguments for anonymisation, provide counterpoints, and demonstrate implications and epistemic costs.

Neil Nelson will give the first keynote of the day, about finding lies in the work of scientists. He argues we need to be able to detect what is not true when we interact with the scientific literature. #PSE8

As of today, on the @pci-regreports.bsky.social home page, you will find my name among amazing researchers who have been a real inspiration at different stages of my researcher journey. I'm so grateful for this opportunity 🙏 I really enjoy the recommender role & I'm ready to take things up a notch

I think some of these points miss the mark. Moreso, I'm concerned that they'll be used by others to smuggle hidden moderators debates back into psychology. 🧵 www.bps.org.uk/psychologist...

Working on a new research cycle for my dissertation

I can understand that citation databases want to limit number of results you can export at once, but setting that number to a 100 is diabolical

👇🏻 this is an excellent opportunity to contribute to a large international project, and the team is more than welcoming :)

I made an error that I found thanks to @lukaswallrich.bsky.social. The code and preprint have been corrected/updated. Effects on false positive rates are smaller and only for alternative and correlation method but I think the overall argument still works.

Coding tip of the day: make sure you leave informative comments in your code

Glad to see Elsevier is investing in important things like suggesting readers that AI reads the articles for them. Nothing screams quality like claiming reading their articles is wasted time

I fucking love buying books.

Hi #openscience friends! As Psych-DS moves forward (stay tuned for an R package update...), we're applying in parallel for renewal of the NIH grant that funds this work. If you (a) have NIH funding and (b) plan or would like to use Psych-DS for resulting datasets, please drop me a line!

ReplicationResearch.org is now open for submissions! Submit replications and reproductions from many different fields, as well as conceptual contributions. With diamond OA, open and citable peer review reports, and reproducibility checks, we push the boundaries of open and fair publishing.

Putting high hopes in this one. Happy birthday to me 🥳

Is anyone else getting this error or am I missing something: Error: 'se' is not an exported object from 'namespace:metafor'? #rstats @wviechtb.bsky.social

www.medrxiv.org/content/10.1... INSPECT-SR: A tool for assessing trustworthiness of randomised controlled trials.

Yet another example of original authors being allowed to say anything they want in replies to critiques unconstrained by verifiable facts. Reply states we didn’t consider things we explicitly did, and says the original article never said things it explicitly did. Read Jamie’s thread for details:

I wrote an R package that creates standardized R project structures that are compliant with @mekline.bsky.social's psych-DS...ish. It also creates additional features for reproducibility and teaching like a readme, license, .gitignore and Quarto templates + can validate existing projects

ERROR @error.reviews was awarded a Commendation from the Society for the Improvement of Psychological Science!

For anyone who’s published systematic reviews, how often did you succeed in getting unpublished data by reaching out to authors? I don’t mean additional/IP data from published papers, but new data or data they could not get published. #evidencesynthesis

A lot of discussions about open science in psychology happened on blogs. I have been archiving them and will make their content available. I remember 37 blogs (with 2827 posts!) but which blogs did I forget, and are not on my list? Please share and reply with any that are missing!

New post! "A Tale of Two Science Reform Movements," in which I compare the recent #Metascience2025 and #SIPS2025 conferences, and find that I am much more at home at one than the other. getsyeducated.substack.com/p/a-tale-of-...

Agreed, I feel like the overall direction of the entire conference felt too abstract and almost like it’s engaging in “meta-washing”

Anyone can do post-publication peer review. Anyone can be a steward of the scientific literature. Anyone can do forensic metascience. Anyone can sleuth. That's why we are launching COSIG: the Collection of Open Science Integrity Guides, an open source resource for all of the above. cosig.net

What came first, the paper idea or the acronym

5. This is the moment of truth. The metascience community could tout this as a win and fundraise off of it, cementing their legacy as useful idiots. Or they can side with science, boldly speaking out about the bad-faith ways the Trump administration is co-opting their language and momentum.

I found this refreshing. erikengdahl.se/autism/isnt/

Autistic adults talk about disclosure: "assumptions and lack of understanding about autism meant that not only did disclosure not lead to the desired effect of having their needs met, but they were also either dismissed or discriminated against" journals.sagepub.com/doi/10.1177/... free

Brandolini underestimated how many orders of magnitude are involved

For people who published/conducted Stage 2 registered reports, have you ever had issues that required significant deviations from the Stage 1 and how have you handled this? Are there any instances where this did not lead to rejection? #openscience

Can I do another PhD 🥺👉🏽👈🏽

I am hiring a PhD student on the meaningful interpretation of effect sizes as part of my VICI funded project. This is a 4 year paid position in a welcoming and collaborative environment. Find out more or apply at www.tue.nl/werken-bij-t...

We have the connection folks... RFK jr will find the cause of autism to be something that Elon's neurolink. can fix. Since there is no longer any kind of an FDA, and he is involved with that, guess who is going to fast pass the "cure". This is so fucking dangerous I cannot even....
