Highly recommend this opportunity! I was on the steering committee about 5-6 years ago and it was incredibly rewarding! (P.S. where did the years go?? 😵‍💫)

I‘m starting a new 'migration log' here: I work in the Netherlands, of course I commute by bike 🚴🏻

Please help us, #MetaScience community! It's time to decide on a forever name for papercheck (scienceverse.github.io/papercheck/). We don't want it to be confused with papercheck.ai, and we plan to check other research artifacts like repo contents, data, code, and prereg. Any suggestions?

Hallo zusammen, mein Name ist Raphael und ich habe kürzlich meinen Master in Psychologie abgeschlossen und im Oktober den PhD im Bereich MetaScience in den Niederlanden angefangen. Bevor ich euch mehr über meinen PhD erzähle, wollte ich aber ein bisschen was zu MetaScience allgemein erzählen:

This week, I'm posting on the German @realscientists.de account! Consider following if you're interested (and speak German)! :)

Better late than never: I graduated last month and started my PhD last week! 🥳 I’ll spend the next four years exploring how to make theory-based predictions of plausible effect sizes! 📚📈 Goodbye, Bochum – I will miss you! And hello, Eindhoven! 🚀

Today is the last day to sign up for the upcoming workshops (on the 16th) and the symposium (on the 17th) of Paul Meehl Graduate School. Don't miss it.

Join us for our next PYMS Journal Club! 📖🚀

Time is running out to register for our pre-symposium workshop and Meta Research Symposium event at Paul Meehl Graduate School Check the information and registration links below: paulmeehlschool.github.io/workshops/

oh noooo

Wow, so they‘ve really gamified this 'preregistration' thing, huh? 🎮🔬 (also love that it says that the topic is metascience)

2 new job opportunities at the @cais-research.bsky.social: - PhD student, team "Research Data & Methods" stellenangebote.cais-research.de/de?id=f50b76 - Researcher, DFG project "SocEnRep - Automation of Reproducibility in Economics and Social Sciences" stellenangebote.cais-research.de/de?id=f50b76

✨ In 'CRediTs for Students', we developed empirically informed materials – such as a supervision agreement and authorship guidelines – for students and supervisors to foster the transparent and systematic recognition of students' contributions to science. osf.io/tygsp/

🎉 Excited to see our project 'CRediTs for Students? – Promoting Student Authorships in Psychology' recognized alongside so many other inspiring initiatives! If you're interested in implementing something similar, reach out! Or check out our OSF page: osf.io/tygsp/.

New blog post: Easily download files from the Open Science Framework with Papercheck daniellakens.blogspot.com/2025/07/easi... Downloading all files in an OSF project can be a hassle. Not anymore, with Papercheck! Just run: osf_file_download("6nt4v")

🚨 Registration is now open for the PMGS Meta-Research Symposium 2025! 📝 Abstract submissions are still welcome—deadline: July 31. Plus: join our mini-workshop on coordination using GitHub on the afternoon of October 16. Find all the details & sign up here: paulmeehlschool.github.io/2025-07-16-s...

Teaching needs more space for moments like these. For curiosity. For honest questions. For the stuff that doesn’t 'need to be on the test'.

So, I just had a real-life “Oh Captain, my Captain” moment during my statistics tutorial. 🧵

Join our online journal club meeting next Monday July 21st (12 - 14 CEST), and discuss a paper with fellow ECRs! This time, we will discuss the following paper: Romero, F. (2019). Philosophy of science and replicability crisis Sign up using this link: forms.gle/gRWf6SEyf2ki... See you there!

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!

First time presenting at a big conference: check! So happy to see how the community of PYMS is growing over the last couple of days, and how people are constantly finding each other to hang out at #metascience2025. This is what PYMS is all about!

At Metascience 2025? Then come to our panel where wonderful @anoukbouma.bsky.social will talk about our work and vision at PYMS! 🚀

Turns out, students actually CAN do scientific work. like conference talks. on student authorship. #SIPS2025 @improvingpsych.org @raphaelmerz.bsky.social

This is especially interesting for anyone planning on manually coding a literature. Papercheck will make this much faster just by using the excellent search_text function and exporting results to an excel file for coding. But is even possible that some coding can be completely automated.

I‘m using Papercheck in my master’s thesis, so feel free to approach me at either SIPS or Metascience if you‘re interested! 🙌🏼

If you'd like to chat about Papercheck with some of our team members, @debruine.bsky.social will be at the Metascience conference, @crist14n.bsky.social will be at the open research summer school by @samwestwood.bsky.social , and @raphaelmerz.bsky.social will be at SIPS!

I wrote a blogpost on something I’ve been thinking about a lot lately: how metascientists could (and should) think more about their users when designing tools and reforms. Would love to hear any thoughts on this topic! #metascience #usercentered

somehow i feel like starting a scientific crisis

I don’t know what it is but somehow this place makes me wanna fabricate data and publish them in high-impact journals… must be something in the water 🤷🏻‍♂️

If your frequentist analysis gives the same result as a Bayesian analysis, that means nothing for either paradigm. No frequentist is bothered that Bayes "works" - they use Bayesian calculations all the time. No Bayesian is bothered that a freq estimator agrees - it's interpretation that is doubted.

My editorial on how journals can earn trust. We often use journal names as proxies for quality. This is bad bc it’s not valid. But it could be. Editors could make journal name a valid signal. And we could place value on journals that show us how they do that. journals.sagepub.com/doi/full/10....

An interesting new paper in Royal Society Open Science charts the prevalence of studies in psychology interpreting the absence of a statistically significant effect as evidence for the absence of an effect. royalsocietypublishing.org/doi/10.1098/...

🚀Very excited to finally see our paper on nonsignificance misinterpretations published! 📈 Together, @smurphee.bsky.social, Aurelio Fernández, Linda Reimann and I investigated the prevalence of "p > .05 = absence of an effect" interpretations. (1/4) doi.org/10.1098/rsos...

Want to make nice graphs with me, starting this summer? I am hiring for two PhD positions at the University of Witten/Herdecke.
