Our department just announced a new Associate Professor position in quantitative research methodology 🇳🇴 One of the favorable qualifications is experience with open science practices + R/Python experience www.jobbnorge.no/en/available...

In large meta-analyses, standard forest plot can become excessively large. One solution is to group the estimates together within studies. I just added an example to the metafor website illustrating this possibility: www.metafor-project.org/doku.php/plo... #MetaAnalysis #RStats

Just arrived at NMBU to deliver a workshop on social media for academics. These are always lots of fun to do

APA: “What if we made it even *harder* for people to read papers in our journals?”

WE ARE GOING TO WIN THE WHOLE THING

Some journals require lay abstracts alongside conventional abstracts. I almost always prefer the lay version because they more clearly describe what was done and what the results mean, which says a lot about how we approach scientific writing

Every AI-managed Frontiers invitation that is sent to someone to review a paper that’s comically outside their field of expertise is one less person that will consider submitting their work to Frontiers, as this reveals how poorly their paper will be handled

I did a double-take on this paper title because I didn’t notice it was in mice when reading the first two sentences

Here's an interesting piece on the use of metrics to measure academic performance. We all know that when a measure becomes a target it ceases to be a good measure, but at least metrics distort behavior *visibly* & institutions can choose the ones to reward nicolaijfoss.substack.com/p/coara-and-...

gonna post 100 likely permutations of the World Cup knockout bracket on bsky and then delete all the ones that were wrong after the final and then claim I predicted everything before the tournament to demonstrate p-hacking for my classes next semester

I was really happy to find a link to raw data in paper I was reading, but this is what I found when I clicked on the OSF link. At least it was better than a CSV file with one cell containing the text: "Data available upon reasonable request"

Please improve acknowledgments sections to better credit research contributors! www.tandfonline.com/doi/full/10.... Our new paper on this topic begins by summarising three pathways to improve crediting of research contributors – 1. Loosen authorship restrictions.

Psychology is in the middle of several overlapping crises—replication, generalisability, theory—but this isn't new. Crisis discussions first appeared in the 1920s (!?). The specific topics have changed but the structure seems kind of similar, maybe we can learn something from this? doi.org/czvw7m

Reminds me of the time I was at a conference in the US and I asked hotel reception the quickest route to walk to a restaurant about 1km away and they seemed stunned I would even suggest walking

Funnel plots and Egger's regression test measure small-study bias, not publication bias, which is a distinction many meta-analyses get wrong. So I made a screencast on how measure publication bias correctly in JASP and R: youtu.be/XiUj4yP8Nsw

Trust in science. Expert opinion, context, and open data all help, and in the era of AI, we should aspire to audit trails that confirm data provenance. Key to trust is accountability of researchers, however, and for that we need identity verification. New blog post. openrxiv.org/trust-signal...

What do you think is your most under-recognised paper and why should people be paying more attention? Go on, take the chance to toot your own horn 🎺

New book haul 📚

As long as a paper's methods are described *somewhere* I don't think it matters where they are located in a manuscript

Many people write grant applications assuming their reader is engaged, but the opposite is more likely. Your evaluators are time- and attention-poor, so you should design your application with this in mind. This slide is part of a talk I'm giving today on writing grant applications

Most autistic students who need accommodations in higher education never get them. In our latest preprint, we describe where the gaps are and what students said about them doi.org/q8js

In our new preprint, we describe the unique needs and experiences of autistic students in higher education osf.io/preprints/ps...

It’s paddle season

Timeline cleanse

Nothing says “emergency” quite like a 2x3x3 interaction effect (p = 0.043)

Social media platforms and how academics use them change, but one thing doesn't

did… did a journal write this?

We have a tradition in our lab: every PhD or Master’s publication gets its own custom mug ☕

Procrastination, 2026 style

A major release of the RoBMA package (4.0.0) is now on CRAN. Main highlights: - fully redesigned interface closely matching metafor - dedicated brma, bselmodel, bPET, bPEESE for single model fits - fit diagnostics features (residuals, influence, etc) (overview at fbartos.github.io/RoBMA/articl...)

Here’s a GIF I put together illustrating the advantage of an allostatic system vs. a homeostatic system for an upcoming talk 🧵

Effect size distributions (ESDs) can help determine small/medium/large effects, but publication bias may lead to imprecision. Iceberg plots visualize a raw ESD against a pub bias-adjusted ESD. Build this using data typically reported in published meta-analyses via our new ‘ESDist’ R package 📦

A meta-analysis is not a ‘easy’ publication. Search strategy development, screening, more screening, data extraction, requesting additional data, risk of bias assessments, the actual synthesis, write up—it all takes time. Many people heavily underestimate the resources required to complete one

Bring back printed course readers! 📗

New preprint: Preregistration is supposed to make research more transparent. But if registry records aren't kept up to date, the transparency benefit erodes. We checked 1,137 psych meta-analyses on PROSPERO and found the records are systematically out of sync with reality osf.io/preprints/ps...

Just want to check again: Has anyone with a PROSPERO systematic review registration received an email reminder to update their registration? The documentation says this is the case, but I've never received anything like this, and neither have a couple of others who responded to this original post

Really happy this paper is finally out. This began as an R script I wrote for a paper in 2016, and the Ben (first author) took this idea and improved it, iteration after iteration, into an R package.

Selecting an effect size for power analysis is hard. Many researchers fall back on Cohen's thresholds, but they have no empirical basis and vary wildly by field. Our new paper offers a better option: field-specific effect size distributions built from meta-analytic data doi.org/10.3758/s134...

My article "Three-Sided Testing to Establish Practical Significance" with @jackfitzgerald.bsky.social is now published in AMPPS! journals.sagepub.com/doi/10.1177/... Three-sided testing is an improved version of TOST that lets you test for equivalence, superiority and inferiority simultaneously.

My superpower is accepting peer review requests weeks apart whose deadlines all somehow fall within the same couple of days

For those with healthy enough boundaries to avoid bluesky over the weekend, here's a thread on my new preprint formalising the Allostatic Theory of Oxytocin (and what it taught me about theory-building in psychology)

Why are oxytocin study results so inconsistent? Methods get most of the blame, but the problem is also theoretical as existing accounts are too vague to falsify. In a new preprint, I formalise the Allostatic Theory of Oxytocin as a computational model osf.io/preprints/ps... 🧵

I always imagined that papers would become quicker to write as I got more experienced with research, but the opposite has happened instead because now I better understand how papers can be improved and spend much more time tweaking and rewriting

According to PROSPERO's documentation, automated emails are sent to reminder authors to update their registrations when their review is completed and to include citation details when it is published www.crd.york.ac.uk/PROSPERO/hel... Has anyone with a registration gotten this automated email?

Computationally formalising a verbal theory is an eye-opening experience because it forces you to openly state all the assumptions that the theory rest on

New preprint! Led by @aisartorius.bsky.social, we ran a meta-analysis on the effect of intranasal oxytocin on appetite + caloric intake. We found oxytocin reduces appetite in clinical populations, but data are too underpowered to draw conclusions in healthy populations doi.org/10.64898/202... 🧵

My first thought was “why create fake authors if you wouldn’t get the credit?”. But then it clicked—this is probably a citation boosting play
