MetaROR, a platform for reviews of research on research, is a success! We have published 24 sets of reviews and have 16 submissions in process. MetaROR now has 9 partners - these are journals that agree to use our reviews when authors submit to them. metaror.org #metascience #openaccess

New global study lead by @psysciacc.bsky.social with @scanunit.bsky.social across 18 languages challenges a classic idea in psycholinguistics: when we read, we don’t always imagine objects in the same orientation as described. doi.org/10.1007/s121...

Academia is brutal: Paywalls, replication crisis, intransparency, inequity, billion dollar donations in peer review, etc. Read in our inaugural editorial how R2 solves these problems. www.uni-muenster.de/Ejournals/in...

Dear Dr. [redacted], It was nice to meet you at the [redacted]! Thanks for thinking of me as a possible reviewer, as I am interested in the topic. However, I decline to review this manuscript - I often do this in the case of journals published by profiteering corporate publishers. For Nature Communications, Nature Publishing Group charges an outrageous US$6990 to authors that has little to do with higher-quality service or journal processes and lots to do with a legacy first-mover advantage that it uses to exploit academia. This is rentier capitalism. NPG funnels papers they reject from their most prestigious outlets to their newer subsidiary journals such as Nature Communications and Nature Communications Psychology, which academics go along with because they don’t (directly) foot the bill, and because, given the pressure academics are under to publish rapidly, they wish to take advantage of the reviews they may have already received from the higher-tier Nature journal. Because we are now live in a world where most studies can eventually be published somewhere, NPG has been able to exploit this by creating their own lower-tier journals and charging high-aspiration authors for the convenience. This practice conflicts with my interest in universities and funders not wasting their money, which is why I do not wish to support it by contributing to the hundreds of millions of dollars of labor that academics donate to corporate publishers. Instead, I preferentially review, and volunteer as an editor for, diamond open access journals that are free to read and publish in. For various reasons, including combating this strategy by which corporate publishers are extending the era in which they profiteer from university funds, many academics and funders now advocate for the Publish->Review->Curate model, in which academics publish their work immediately (on preprint servers, which prevents gatekeeping by editors), and then get it peer reviewed, preferably through low-cost…

Today's email to an associate editor, declining to review for a big corporate publisher. This one focuses on Nature Publishing Group's practice of funneling rejected manuscripts to their newer journals with hefty APCs.

Migrated my book to another domain elliedegb.quarto.pub/psychometrics/ . It's a free resource on psychometric validation of instruments in R. Please share!

Defended my dissertation yesterday so I guess I’m (unofficially) Dr Leong now 😭

Share your thoughts on the Netherlands Code of Conduct for Scientific Integrity The current version of the "Netherlands Code of Conduct for Scientific Integrity" dates from 2018. Every few years, a committee reviews whether the code still meets current requirements, such as…

Yesterday with the META/e group at Eindhoven we discussed the draft of the new Dutch Code for Research Integrity: www.nwo-i.nl/en/news/2025...

It is great to see how much transparency and FAIR data and code will become the default expectation to adhere to research integrity.

When and How to Deviate From a Preregistration, with Prof Daniël Lakens Prof Daniël Lakens will share guidance on appropriate circumstances and methods for deviating from a pre-registration

When is it appropriate to deviate from a pre-registration, and how should this be done? 🧐

Make an effect size prediction!

@jamiecummins.bsky.social and I are replicating Balcetis & Dunning's (2010) "chocolate is more desirable than poop" (Cohen's d = 4.52)

Let us known in the replies what effect size you think we'll find. Details of the study in the thread below.

This effect deserves a cult following and I will be part of it.

Where to publish reproductions and replications? (At ReplicationResearch.org of course) But seriously: There are several journal dedicated to replications and reproductions!

New Nullius In Verba episode on p-hacking (Part 1 of 2). We discuss why it is useful for a single term to describe all practices that untransparently inflate error rates, and what these practices are.

We started @metaror.bsky.social MetaROR.org in part because of the absence of a journal that publishes metascience. But rather than a traditional journal, as metascientists we wanted to explore the next frontier - Publish, Review, Curate.

New study in AMPPS:

Clinical psychologists favour statistically significant results.

(presumably true in all fields, I'd say. Bias against null findings)
