Is anyone willing to share their slides on philosophy of science for undergraduate (statistics) students, especially as it pertains to the hypothetico-deductive framework? Here are my current notes on the topic: lnkd.in/eB-TZGDK

Any experiences with "Journal of Computational Social Science"? I reviewed a manuscript that should have been desk-rejected (grammatically incorrect, not embedded in relevant literature, ad-hoc and nonsensical analysis decisions); the decision was "minor revision" based on ONLY my review. How!?

Finally! 🤩 Our position piece: Against the Uncritical Adoption of 'AI' Technologies in Academia: doi.org/10.5281/zeno... We unpick the tech industry’s marketing, hype, & harm; and we argue for safeguarding higher education, critical thinking, expertise, academic freedom, & scientific integrity. 1/n

I was reminded today of the heroic work done by @eikofried.bsky.social and @robinnkok.bsky.social to see what information Elsevier collects on academics and was re-horrified. 🧵 (1/5) eiko-fried.com/welcome-to-h... #academicsky

Day 2 Keynotes kicked off with Laura Nelson's inspiring presentation, “Why Qualitative Research Needs Computational Social Science”. What is the state of this maturing field called qualitative computational methods? What are the ongoing debates and futures? #ic2s2

Loving @ic2s2.bsky.social , but I wonder if we're asking the right questions. Is "How can I outsource this task to a proprietary, black box, resource-intensive, often un-validated LLM?" when fit-for-purpose classifiers abound a computational a computational research question? Or even scientific?

At my preconference workshop @ic2s2.bsky.social participants will conduct a *fully reproducible* and *FAIR theory based* simulation study. The full interactive tutorial is in the theorytools R-package docs: cjvanlissa.github.io/theorytools/... And slides: cjvanlissa.github.io/worcshop/ic2...

To be FAIR: Theory specification needs an update! Theories that others can reuse and update help navigate the "theory crisis". The theorytools R-package now has tutorials showing how to make theories FAIR and use them to select covariates, simulate data, etc osf.io/preprints/ps...

🚨 Program Highlight! We're thrilled to welcome @cjvanlissa.bsky.social as our keynote speaker on June 5th! He’ll present his work on FAIR theory—a framework to make theories Findable, Accessible, Interoperable & Reusable—and share his path as a meta-scientist. #openscience #FAIRtheory #metascience

I'm hiring a PHD candidate in Machine Learning-Informed Formal Theory Construction. Please encourage talented students to apply, or reach out if you want to collaborate. Looking for machine learning, theory development, and programming skills, and interdisciplinary interests! See tiu.nu/22752

For @tilburg-university.bsky.social 's #sciencequest podcast, I discussed the question: Do we still need scientific models? Can we not just use AI to answer all of our questions? The interview is in Dutch, accompanying text in English: www.tilburguniversity.edu/magazine/ove...

Extremely disappointing & cowardly. The American Psychological Association is rescinding diversity requirements. Not due to any actual mandate from the federal government, but only because it may *someday* face pressure from the government www.nytimes.com/2025/03/27/h...

Went bouldering with Noah van Dongen and @cjvanlissa.bsky.social. Noah got a Veni grant this year, Caspar a Vidi, and I received a Vici, so we had to make this picture 😊 We will also work together in our projects on improving theorising in psychology!

Alle Europese landen zijn serieus werk aan het maken van het aantrekken van Amerikaanse wetenschappers. Behalve de Nederlandse coalitie van "boekhouders en ruziemakers", zegt Rob Jetten van D66. Het kabinet is dit ook niet van plan, zegt Dick Schoof.

Bridging the gap between #R package documentation and #openscience Open Educational Materials, I'm embedding formative quizzes in the package vignettes (based on @debruine.bsky.social 's webexercises)! Check the development version of github.com/cjvanlissa/t... to see how it's done.

To be FAIR: Theory needs an update! FAIR theory can be shared, reused in analysis software, and updated based on new findings. Using existing #openscience infrastructure, it streamlines collaboration, reduces research waste, and accelerates cumulative knowledge development osf.io/preprints/ps...

Revising papers became easy when I discovered James Conigrave's "revise" package, which inserts tagged snippets from a manuscript into a revision letter! No more back-and-forth, no more consistency checking. Now on CRAN, may it save you as much time as it did me! cran.r-project.org/web/packages...

Who is "the researcher of tomorrow"? Will we be replaced by AI? I really enjoyed discussing these issues in front of a live audience with Studium Generale Tilburg The video starts on the panel discussion, but make sure to check Nathan Wildman's inspiring lecture too www.youtube.com/watch?v=0oRx...

Tired but happy to say this is out w @andreaeyleen.bsky.social: Are Neurocognitive Representations 'Small Cakes'? philsci-archive.pitt.edu/24834/ We analyse cog neuro theories showing how vicious regress, e.g. the homunculus fallacy, is (sadly) alive and well — and importantly how to avoid it. 1/

Is the AI bubble bursting? Maybe for ChatGPT, but there is now widespread support for automating everyday tasks. Academics build small specialized models, trained on high quality data, informed by domain knowledge. It's time to incorporate these into everyday workflows instead of "asking ChatGPT".

Open Science and Open Source only with Diversity, Equity, Inclusion and Accessibility. Inclusion is essential to science, and science is only worthwhile if it lifts everyone up together. ropensci.org/blog/2025/02... #OpenSource #OpenScience

Did this interview (Dutch) for @tilburg-university.bsky.social series "The Career Path", about interdisciplinarity, open science, and collaboration. Hopefully, this will encourage young scholars to pursue their curiosity and contribute to research that matters. www.youtube.com/watch?v=9z5h...

DeepSeek powerfully demonstrates the value of open source and the importance of optimization. I hope it will also help democratize LLMs. Watch it run on a Raspberry Pi, accelerated by an AMD graphics card! youtu.be/o1sN1lB76EA?...

Not every study needs super-complicated statistics, sometimes all you need is a contingency table. Now, thanks to Yasin Altinisik, Rebecca Kuiper et al, you can test informative hypotheses for contingency tables with the gorica R-package! link.springer.com/epdf/10.3758...

Open science is efficient: reusable code, data, results, and educational materials saves unnecessary work. Wen facing cutbacks, it's a bad idea to cut back on practices that increase efficiency! universonline.nl/nieuws/2025/...

It was a pleasure to contribute to this Participatory Value Evaluation on Research Funding by the Dutch Young Academy; one main conclusion - that dependence on grant funding threatens academic freedom - is more relevant than ever in the context of cutbacks. dejongeakademie.nl/en/news/2937...

Zotero is great and I think that anyone who needs to organise and cite more than a handful of references should be using it. Here's an intro to Zotero that I made for my undergrad students (but the info is relevant for anyone new to Zotero). Full vid [13 mins]: youtu.be/SlUHjOqVCyU Preview ⬇️

Was recently reminded of David Hand's alternative missing data taxonomy renaming the (in)famous taxonomy MCAR/MAR/MNAR by Donald Rubin to NDD/SDD/UDD. I am not generally a fan of renaming things, but this might be the exception Source: rss.org.uk/training-eve...

I frankly believe everyone should do this. OA, based on huge APCs, is just an example of the perfect co-optation of a once good idea, making it quite horrible, while enriching publishers in the process. moreover, subscriptions were paid from library budgets; now, APCs come from research funds...
