No industry is perfect. But the imbalance is hard to miss. One sector must prove its products are safe & effective. The other profits by avoiding that responsibility. If we care about transparency and accountability, scrutiny shouldn’t be one-sided. (Source: For The Greater Glory of Science) #EpiSky

Yes, ChatGPT can help you write #rstats code, but so can this old Wiki I created with example code used for common data wrangling needs. Who knows, you might find some gems in there.🤷‍♀️ github.com/Cghlewis/dat...

1. Ran Tian: Statistical Practice in Sport and Exercise Science: A Meta-Research Study. We studied 146 studies. Most used multilevel models or t-tests/correlations/ANOVA. In 27% the wrong methods were used (statistical test did not match data structure). Collaborate with a statistician! #AIMOS2025

Has anyone tried the trackdown package for collaborative quarto editing? Love writing papers on Quarto, but switching back to Word for co-author edits is still an awkward missing link claudiozandonella.github.io/trackdown/

ellmer 0.4.0 is out now! New features include Claude caching & file uploads, support for newer OpenAI responses API, web search tools, and better security. Read more at tidyverse.org/blog/2025/11... #rstats

I recently discovered Conventional Comments (conventionalcomments.org) for providing a pseudo-standard set of labels for feedback and just tried it for an article review and it was really helpful to specify issues vs. thoughts vs. suggestions, etc. Hopefully it's helpful for the authors too!

TU/e has gained a new research centre: META/e. Daniël Lakens and Krist Vaesen were among the founders of this knowledge hub for metascience—research aimed at improving the practice of science itself. “We want to be a home for every researcher who occasionally wonders: what are we even doing?”

Registration is now open for our Quarto workshop at Paul Meehl Graduate School! Join us on December 12 in Eindhoven to learn how to use Quarto for reproducible research and communication. More details and registration here: paulmeehlschool.github.io/2025-11-03-q...

It seems, I was not up-to-date. Discipline specific examples have already been discussed, or should I say "will be discussed" ;) Your output is insane! @crist14n.bsky.social sportrxiv.org/index.php/se... bsky.app/profile/cspa...

The package formerly known as papercheck has changed its name to metacheck! We're checking more than just papers, with functions to assess OSF projects, github repos, and AsPredicted pre-registrations, with more being developed all the time. scienceverse.github.io/metacheck/

The term #estimand is now part of the technical language of trials - but it remains a concept that many find hard to understand. Recent work has aimed to make the term more accessible to researchers, patients & public 1/8 #MethodologyMonday #127

Just discovered this great preprint by @crist14n.bsky.social @lakens.bsky.social sportrxiv.org/index.php/se... I wish someone had given me tutorials/easy-to-understand explanations like these when I was doing my bachelor's degree!

New paper finds that selective reporting remains the most replicable finding in science: journals.sagepub.com/doi/full/10.... I especially like their new exploratory metric 'p-values per participant'. Some papers had 11 p-values per participant! 🤯

There still seems to be a lot of confusion about significance testing in psych. No, p-values *don’t* become useless at large N. This flawed point also used to be framed as "too much power". But power isn't the problem – it's 1) unbalanced error rates and 2) the (lack of a) SESOI. 1/ >

I'm excited to share a new version of the Air formatter for #rstats, with support for tabular formatting! Super useful with `tibble::tribble()` calls or `data.table::fcase()`. It's currently experimental as we're looking to get feedback on the feature, so please let us know what you think.

How FAIR is shared data in psychology? We analyzed 11,384 datasets (2013–2024): They're findable, but less reusable! What relates most to differences in FAIRness? #Repository choice. 👉 Preprint: doi.org/10.23668/psy... @mariogollwitzer.bsky.social @kaisassenberg.bsky.social #metascience #SciSci

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?

New blog post! Let's say you have two measures meant to capture the same confounder. They're highly correlated. Can you still proceed with your regression analysis? (I admit, the title is a bit of a spoiler) www.the100.ci/2025/10/13/i...

Should statistical software that estimates causal effects also tell you the causal assumptions under which that estimate can be interpreted as causal? I don't know but my PhD student Maurice Korf has some thoughts (and software) to get the conversation going: academic.oup.com/ije/article/...

I'm starting to explore {simDAG}, a nifty #rstats package that has a nice API for specifying DAGs and then simulating data from them: robindenz1.github.io/simDAG/

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.

What percentage of the health research funding pot do you think goes on methods and meta science? Around 2% (if you add together all mention of research design and methodologies across all areas from research.hscni.net/sites/defaul...) Just 2% spent on the part that underpins EVERYTHING we do.

I'm exited to announce a new resource about making slides with quarto and revealjs. This book is the combination of all the work I have done in this area, reordered and polished up There isn't a lot of new information yet, but this format allows me to add more easily slidecrafting-book.com #quarto

So a spurious correlation from an observational study is “gold standard science”, but testing vaccines in multiple RCTs with over 30,000 participants each is not?

Tidy simulation: Designing robust, reproducible, and scalable Monte Carlo simulations #StatsSky arxiv.org/abs/2509.11741 It is not formally linked to the {tidyverse}, bit affinity is obvious. The paper does a solid job in describing the simulation workflow, could be useful for intros to simulation

Excited to finally have my first paper officially published! "How Do Psychology Journals Handle Postpublication Critique?" is now online with AMPPS.
