Screen shot of section 1.1 of the report "vision for a new publication culture"

The governing body for 14 Dutch universities (UNL) has published a "Vision on Publication Culture" that is so inspiring and forward thinking. Worth a read for those trying to changes publishing and research assessment practices.

Come join this project to study a form of peer review that focuses on the methods instead of the results.

I'm already a postdoc on the team so hit me up if you have any questions!

Checking for Statistical Errors in Primary Studies: A Way to Improve Meta-Analytic Evidence? — Meta-Research Center This blogpost was written by dr. Olmo van den Akker. He is a postdoc in our department working on two projects: a systematic review of studies that simulate p-hacking, and a randomized controlled tria...

Should we use error checking tools like Statcheck and GRIM to automatically check for errors in studies in meta-analyses?

I wrote a blog post with some insights from a hackathon where we scrutinized this idea.

On 24 April, I will speak at the @emspofficial.bsky.social conference about making studies using patient registry data more transparent.

It means a lot to me because a close friend was diagnosed with Multiple Sclerosis just last year. Hope to learn a lot there!

Promised Data Unavailable? – I’m Sorry, Ma’am, There’s Nothing We Can Do — Meta-Research Center This blogpost has been written by Michèle Nuijten. Michèle is an assistant professor of our research group who investigates reproducibility and replicability in psychology. Also, she is the developer ...

I wrote a blog for the Meta-Research Center expressing my infinite frustration about not getting data. What else is new, you might think? Well, I added an extra layer of annoyance directed at the journals who do NOTHING to enforce promised data sharing.

Introducing the EEG and ERP Methods Template: Q&A with Gisela Govaart and Antonio Schettino Interview with Gisela Govaart and Antonio Schettino, developers of the new ERP preregistration template on the Open Science Framework (OSF).

Now available on the OSF as part of a growing collection of preregistration resources, the new EEG & ERP Methods template guides researchers through every stage of ERP study planning. In our Q&A, two of its creators share how the template can help researchers at all stages:

New tool exposes scale of fake research flooding cancer science A new machine learning tool has identified more than 250,000 cancer research papers that may have been produced by so-called “paper mills”.

“If fabricated studies make their way into the evidence base, they can mislead real scientists and ultimately slow progress for patients."

Published in The BMJ, a new AI tool developed by @aidybarnett.bsky.social and colleagues has exposed the scale of fake studies flooding cancer research.

Is ‘open science’ delivering benefits? Major study finds proof is sparse It’s hard to measure social and economic impacts of making papers and data free, researchers say

#OA articles are cited more, help citizen scientists learn more about the topic they've helped on, but there’s little strong evidence they have other long-lasting effects on research, or many economic and social benefits www.science.org/content/arti...

Proposal to use more nicknames when talking about scientific researchers, the fun of which is nicely illustrated by James "cheaters' bane" Heathers in his acknowledgement slide.

ROB-ME: a tool for assessing risk of bias due to missing evidence in systematic reviews with meta-analysis Various methods are available to help users assess whether selective non-publication of studies or selective non-reporting of study results has occurred, but not its impact on a meta-analysis.

What is the best reporting guideline acronym? ROB-ME by @mjpages.bsky.social gets my preliminary vote.

Any other good ones, #AIMOS2025?

We are about a month away from releasing a complete refresh of the OSF user interface. The team has been working on this for a very long time, and we are very excited to be able to share it soon. A preview picture:

- Journals should state what their aims and scope are from the outset and implement mechanisms to assess whether they achieve those aims. This could also be things like "we want to publish high risk research"
- Meta-research is necessary to find out which journals deserve prestige

- "The replication crisis forced changes in transparency for the research itself, but not for the publication process"
- We need to raise our expectations for journals? How? Nullius in verba (don't take their word for it!)

Many interesting tidbits in @simine.com's talk. A selection:
- Journal prestige depends on factors like aims and scope, selectivity, and impact factor, but changes in these factors do not always lead to changes in journal prestige - journal prestige is sticky

There is also a publish-review-curate publishing platform specifically dedicated to meta-research: metaror.org

Send your studies on peer review there and be part of the future of science!

eLife (talk by Nicola Adamson) uses a publish-review-curate method and uses common terms to assess manuscripts.

For strength of evidence: exceptional, compelling, convincing, solid, incomplete, & inadequate

For significance of findings: landmark, fundamental, important, valuable, & useful

Christos Kotanidis checked differences in abstracts between submissions and published papers & assessed whether these differences indicated higher or lower research quality.

Abstracts typically improved, especially in big five medical journals. Evidence for the effectiveness of peer review?

Andrea Corvillon on distributed vs. panel peer review at the ALMA Observatory:

Most experienced PIs no longer have the best ranks in a distributed review system, but why that is remains unclear.
