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! 🚀

”Using vibe-coded, unvalidated forensic meta-science tools to evaluate the trustworthiness of published research risks holding authors vs. tools to unequal standards. The solution is less vibe-coding and more validation.”

9 days left to submit an abstract to the 9th edition of the Perspectives on Scientific Error conference that will take place in Copenhagen, Denmark, 27–29 January 2027, errorsin.science. It's my favorite conference combining philosophy of science, metascience, and statistics.

We are excited to announce that we are going to broadcast the second day of Meta-Research Symposium 2026 (this Friday on October 9th) for those who were interested but unable to join in person. You can join the meeting using this link: teams.microsoft.com/l/meetup-joi...

Did you check out our Reproducibility 2026 conference program yet? 👀 We have three great sessions packed with keynotes, journal clubs, and opportunities to connect and discuss reproducibility. Here are some highlights from the program:

New Blog post: Which Data Repository Should you Use? In light of OSF closing down, I compare Zenodo, Dataverse, ResearchBox, PsychArchive, and local repositories on six important dimensions. If you want to know which to pick: It depends! daniellakens.blogspot.com/2026/08/whic...

The Metacheck Shiny app to download all private OSF Repositories is done. The manual is updated, and everything is in the dev branch on GitHub. As a bonus, we explain how you can run repo_check, data_check, code_check, and codebook_check on your repository with 1 line of code. Launch next week.

ECRs, sign up now for the 2026 Meta Research Symposium in Eindhoven 8-9 Oct! This year we are collaborating with the Paul Meehl Graduate School to bring together ECRs in meta-science for a workshop, hackathons, social activity, and presentations See you there!

The Metacheck team is busy building an improved version of the osf_download function (www.scienceverse.org/metacheck_bo... ). You will soon be able to use metacheck to download all files, wikis, and meta-data. You will also be able to upload everything to Zenodo.

Perspectives on Scientific Error 2027 is heading to Copenhagen, Jan 27th to 29th PSE brings together philosophers of science, statisticians and metascientists around 1 question: how do errors get into the scientific record, and what can we do about them? Register your interest at errorsin.science

Any tips on a data structure to use when wanting to evaluate agreement between multiple coders (3/4) that coded multiple variables (~15)? I made a big df with a column per var per coder and a column that gives TRUE/FALSE about the agreement between the coders per var, but it is... messy...

Meta Research Symposium 2026, 8-9 October 2026, TU/e Eindhoven paulmeehlschool.github.io/workshops/sy... Seems like a wonderful event for ECRs doing meta-science. I'll give a workshop on "How to use AI tools, agents, LLMs, and automation to improve open science practices" Hope to see you there.
