We've been asked what the most important thing we can do to improve research culture. My answer, the only answer, is to withdraw immediately from university rankings. bsky.app/profile/stat...

Writing some paragraphs about odds ratio and, more generally, different scales in nonlinear models. Any favorite articles on odds ratio?>

Our cluster Machine Learning for Science is up for 7 years more funding!

I need your input! Are there any good AI tools which can work on the reference section of a manuscript? i.e., you have a manuscript with an incomplete reference section and the tool can proactively find missing papers and information (e.g., page numbers). Like what journal production teams do.

New preprint w/ @christophvoelter.bsky.social et al. Individual differences in great ape cognition across time and domains: stability, structure, and predictability 48 apes 🦍, 10 tasks 🧠, 10 sessions📊, 1.5 y📅 ✅ Stable individual traits ❌ No g-factor 🤝 Social ≠ non-social 🔗: osf.io/preprints/ps...

This highlights the point that comparisons between humans and machines are continually muddied by a lack of distinction between evolution and development, both of which contribute to learning in the broad sense.

Since traveling to #cogsci2025 may be particularly difficult this year, we’re hosting a local workshop in Tübingen! 📅 July 24 | Talks & posters + catering supported by @ml4science.bsky.social Open to *everyone*, even without an accepted paper/abstr. 👉 Register by July 1: forms.gle/v6VtEE6UqYw5...

You don't want to miss this preprint (soon to be posted) about the many sins and crimes of p-curve procedures. See a quick tl;dr below. They were prematurely introduced into the science reform literature without doing the foundational theoretical work needed for all statistical methods.

#OCD is a understudied disorder, meaning that we know way too little about the underlying (brain) processes. We have thus built the Brain Explorer app www.brainexplorer.net where everyone can easily contribute to understanding OCD. #MentalHealthAwareness @tueneurocampus.bsky.social @ucl.ac.uk

Thanks to everybody who chimed in! I arrived at the conclusion that (1) there's a lot of interesting stuff about interactions and (2) the figure I was looking for does not exist. So, I made it myself! Here's a simple illustration of how to control for confounding in interactions:>

“There is far too much power in the hands of professors in the German system,” says @leising.bsky.social. My latest @nature.com story digs into efforts to tackle the entrenched structural heirarchy that enables academic bullies.

FYI: The Spencer Foundation, Kapor Foundation, The William T. Grant Foundation, and the Alfred P. Sloan Foundation have collaborated to offer $25K rapid response grants. "This rapid response bridge funding opportunity is for scholars and teams whose grants have recently been cancelled by NSF."

I created this reading list on theory in psychology a while back, so it probably needs an update! Would love any recommendations for papers to include – maybe I can turn this into a syllabus of sorts. PDF of this reading list here: williamngiam.github.io/reading_list...

🙌 Hot off the presses @natcomms.nature.com!

Our new preprint by Claudia Neuendorf!! Is social network information useful for prediction? Using a social network dataset of 46,000 students in 2,000 classrooms, we predicted various class-level outcomes from 313 social network metrics with machine learning methods. osf.io/preprints/ps...

Super excited for #AERA2025 to kick off tomorrow! As a former Coloradan and frequent visitor who currently lives at sea level, while we're in the Mile High City I highly recommend keeping well hydrated and looking for signs of altitude sickness. It's a thing! en.wikipedia.org/wiki/Altitud...

An instrument is not reliable or valid. Viewing validity as an argument, based on multiple types of validity and reliability evidence, addresses concerns about alpha, in particular. #PsychSciSky #AcademicSky #EduSky doi.org/10.1007/s106...

Okay appendices are getting out of control.

Four large Dutch universities, including Leiden University where I work, have decided to throw international psychology bachelor programs under the bus in an effort to appease the rightwing government. Here's my blog why this is a terrible idea. eiko-fried.com/cutting-inte...

This rigorous and critical meta-analysis of the existing experimental research on the effects of ChatGPT on learning and higher-order thinking may be more valuable for the critiques of the literature it raises than its findings. Kudos! doi.org/10.1016/j.co... #PsychSciSky #AcademicSky #EduSky

Really nice new paper by Jingyu Zhang, Oliver Lüdtke, and Alexander Robitzsch on the performance of doubly robust estimators of the ATE. A great example of clear writing and reporting, useful visualization through tables, and a review of modern literature. osf.io/5uj2f_v2

Proudly presenting the (for now) final version of "Why experiments work." To share the materials in a slightly more professional manner, I added a "Resources" page to my website: juliarohrer.com/resources/. That was long overdue anyway; now there's also a curated list of my papers and blog posts.

We @asapbio.bsky.social are planning some work on evaluating the community friendliness of preprint servers. Which factors matter to you, the community? For me = strong governance, transparent policies, good metadata, non-profit stewards, open licensing.

Developmental psychologists: Look! Children have amazing capacity!! Educational psychologists: How terrible! Children do not perform well!

Gave a talk to our PhD students today, and feeling appreciative of all the recent methods work on improving common practices. Thanks to all the authors who work to make their work accessible, especially on social media. A few articles we discussed:

Boy do I have the right measurement instrument for you.

“Ultimately, language is both an enhancement and a constraint, a double-edged sword that structures thought while simultaneously obscuring other modes of being,” argues Jeremy I Skipper. | iai.tv/articles/lan... #philsky #langsky #consky

I'm increasingly uncomfortable with publishing my work open access using a CC-BY licence, as required by many goverment funders. Unlike CC-BY-NC, this permits the work to be fed into thieving large language models for commercial gain. Am I the only one who's unhappy with this? #AcademicChatter

1/7 Our paper on individual variability in decision-making is finally out in @nature.com! Inspired by the classic work by Mante and Sussillo, we trained many rats to solve context-dependent decision-making, and we found that different brains use different neural mechanisms to solve the same task!

New blog post! In which I explain the issue with mediation analysis and sketch out one way to deal with the underlying causal inference problem -- in just a bit over 1,000 words! If you have never found the time to read up on this, now is your chance. www.the100.ci/2025/03/20/r...

Hope to see more papers like this that question the performance and trade-offs of more complicated and newer methods with a sample of datasets (not just simulations that can benefit from cherry picking). Combats the publication bias towards new methods and demonstrates on-going comparative work.

Tens of thousands of psychological measures have been created, but 79% are not reused more than twice. In a new article in NHB lead by @faridanvari.bsky.social and @ruben.the100.ci we quantify this fragmentation in psychology's measures and propose solutions. www.nature.com/articles/s41...

If you're thinking about attending the Psychonomic Society meeting in Denver this fall (Nov. 20-23), this pre-conference meeting, Symposium for Individual Differences in Cognition (organized by Andy Conway), may be of interest to you.
