"The proof established by the test must have a specific form, namely, repeatability." (Dunlap, 1926). And researchers have more and more done so. Read why replications are important and how the last years have seen a strong rise of replications in our open handbook: forrt.org/replication_...

Just learned about this diamond journal, which has apparently been running since 2015! Looks like a very nice place for any meta-sciency work & probably deserves some visibility. septentrio.uit.no/index.php/no...

The Münster Replication Games will take place on November 28, 2025! + 1 day event to conduct reproduction/replication + connect with fellow researchers interested in OS + refine your coding skills + become a co-author on a meta-paper Register here: indico.uni-muenster.de/event/3526

Have you ever heard of predatory journals? Our new study—published this week in Journalism Practice—suggests many science journalists haven't. When they were familiar with predatory journals, most said they weren't worried, confident they'd "be able to spot one if they saw one." Details in 🧵👇

At the FORRT Replication Hub, our mission is to support researchers who want to replicate previous findings. We have now published a big new component with which we want to fulfill this mission: An open access handbook for reproduction and replication studies: forrt.org/replication_...

If you are preparing your bachelor statistics course and would like to add optional material for students to better understand statistics on a conceptual level (see topics in the screenshot) my free textbook provides a state of the art overview. lakens.github.io/statistical_...

🚀Making Replications Count Hackathon - in-person🚀 3 days. 2 open tools. 1 goal: make replication studies impossible to ignore 📅22–24 Oct 2025 | Münster, Germany ✈️Travel & accommodation covered (UKRI-funded) Find out more below 👇 #OpenScience #Metascience #Replication #Hackathon #CodingForScience

Thank you for this very impressive resource of 50 (!) reproducibility/replicability metrics; also includes a searchable online table at rachelheyard.com/reproducibil...

Another one on the list of public communication about researchers wasting tax money by Focus+: "The big business of fake research" a few months after Maithink X's "Tax scandal: science behind paywalls". Ironically, it's paywalled... www.focusplus.de/wissen/gross... www.zdf.de/video/shows/...

We’re beyond honored to receive the SIPS Mission Award 🏆 & thrilled to have received 5 SIPS Commendations 🏆 for projects across our 4 core pillars: Metascience, Social Justice & DEIA, Community, and Education in OS. We are so grateful to all contributors who made this possible 💜 [All links below]

A new preregistration template for simulation studies is now live on OSF. Thanks to the creators and the preregistration template working group for proposing and shepherding this to make it available to users. See the post if you would like to propose a new template. www.cos.io/blog/introdu...

"Rather than simple scams targeting naive researchers, researchers face a complex spectrum of behaviours ranging from outright fraud to questionable practices even by established publishers."

Experimentology is out today!!! A group of us wrote a free online textbook for experimental methods, available at experimentology.io - the idea was to integrate open science into all aspects of the experimental workflow from planning to design, analysis, and writing.

Some benefits of replication studies for science in general, and also direct advantages for Early Career Researchers! @aufdroeseler.bsky.social

@maithinkx.bsky.social / @jensfoell.de discussed commercial scientific publishing as a "tax scandal" and "waste of tax money". While I agree, it is very frustrating to see them miss 99% of solutions for this problem, suggesting that researchers are not interested in solving it.

Lots of food for thought: "The fact that we collectively don’t see it as a colossal moral failing that we haven’t figured out a way to get our work done without having to routinely cut corners in the rush for fame and fortune is deeply troubling."

Old preprint alert: Although I have slowly transitioned from research to "research on research", I keep coming back to assimilation and contrast phenomena: They have been described in perception (psychophysics) and cognition (expectations, estimation, persuasion, social judgment).

German science organizations publish new strategic paper on #OpenScience and #ResearchAssessment frameworks: "The future development of assessment processes for research activity in the context of open science" DE: doi.org/10.5281/zeno... EN: doi.org/10.5281/zeno... Excerpt:

And yet another one in the ever increasing list of analyses showing that top journals are bad for science: "Thus, our analysis show major claims published in low-impact journals are significantly more likely to be reproducible than major claims published in trophy journals. " […]

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-...

Just a reminder to use B!SON to get journal recommendations based on title, abstract, and citations of your manuscript. The project is open source und for each recommended journal it lists APCs, Plan S Compliance, License, peer review type, time until publication, etc.: service.tib.eu/bison/about

For open access journals, with higher impact factors come higher APCs (doi.org/10.1162/qss_...). I think that rather than mindlessly relying on citations, we should look at how responsibly researchers are handling tax money: eg how much money they have spent on OA publications.

Together with @tobiasrebholz.bsky.social and Julia Groß, we developed a common assimilation model for advice taking, hindsight bias, and anchoring: These phenomena have many similarities (robust, assimilation to external cues) and can easily be integrated. But there is one key difference. 1/3

This is shocking behaviour by Wiley; the stated justification does not stand up. I will not be doing any peer review for Wiley journals in future.

Reviewers ahoy!

I think that this is again showing that publishers' interests are not aligned with scientific ideals: Open peer reviews organized by researchers? Researchers owning copyright to their own work? Researchers being able to choose between journals instead of vice versa? Not with Wiley.

New Replication Project in sport and exercise science shares it results: Out of 25 replication studies performed, 56% yielded significant results, but only 7 (28%) revealed a similar effect size. Several problems related to the quality of are discussed. link.springer.com/article/10.1...

'Metascience won't solve the replication crisis' At Metascience 2025, @flavioazevedo.bsky.social, Katherine Button, @lukaswallrich.bsky.social, @forrt.bsky.social, and I will be talking about lots of projects with one common goal: Supporting replication research Registration: lnkd.in/eniwef3b

This is getting out of hand - now they want to re-publish a correction of mine!

It is wonderful to see much interest in #openscience in the Call for Papers of the German #DigitalHumanities association, such as the replicability of reported findings: dhd2026.digitalhumanities.de?page_id=18&l...

2 At first glance, section 3 might look like a really good thing. A lot of these are pillars of the science reform movement. But we've already seen these principles used for the purpose of agnogenesis—creating doubt around scientific findings to stave off regulation or push a political agenda.

The PCI Psychology website is live! psych.peercommunityin.org We're working hard to be ready for launch (planned May 2025) but there's plenty you can do in the meantime to help it along. Go check it out! #psychscisky #scipub

The book of abstracts from our Replication Research Symposium is now available: zenodo.org/records/1548... I had a blast inviting dozens of people whose work I admire to Münster and discuss with them my favourite research topic. Thank you!

'We cannot solve the replication crisis without replications': Looking forward to talking about the @forrt.bsky.social and #MüCOS replication research journal later today at #SIPS. Here is a plot on the number of replications that have been published based on our #ReplicationDatabase. osf.io/xat5s
