Shape the future of social science as a PhD student of machine learning-informed theory construction, based on patterns in high-frequency longitudinal data! You will be part of vibrant communities like the INSIGHT Lab, Theory Methods Society, and Tilburg Experience Sampling Center tiu.nu/23721

Working in modern academia means spending 75% of your time being lectured by admins about not following minutia details of 100+ page handbooks (often now LLM-written) and making endless formatting tweaks to documents you need approved for the work you’re supposed to spend 100% of your time doing.

EU scholars should be digitally autonomous, free from unreliable US big tech. In this article I discuss what YOU can do, which lessons the COVID-19 crisis teaches us, and how we can build on the most recent successful culture change in academia (open science) www.scienceguide.nl/2026/03/digi...

💭 Come work with me, Mark Hoogendoorn, and Dimitris Rizopoulos! We are offering a 3 year PostDoc to do research on the intersection of machine learning (ML) and statistics. 🔢 💫 You will be part of the Stress in Action consortium: stress-in-action.nl/science-of-s... Vacancy: lnkd.in/ewN5T6AA

The "Theory Paper Format" is a template for writing psychological theory papers, developed by the Taskforce Theoretical Psychology (Lorentz Workshop, 2025). Use it to structure your theoretical paper, or (for editors) consider creating journal space for theory papers doi.org/10.17605/OSF...

New post! "Valuing the Process vs. the Product in Research," in which I try to describe some of the tensions around using GenAI/LLMs in scientific research, and why it can be so difficult to have productive conversations on the topic. getsyeducated.substack.com/p/valuing-th...

Does your R-script work on your computer? Want to make it fully reproducible on ANY system, now and in the future? In this video, I demonstrate how to turn R scripts into reproducible, version-controlled projects with worcs, renv, targets, and testthat to verify reproducibility. youtu.be/3mgRFMr5APU

Everyone’s talking about the "theory crisis" - but do we fix it with formal- or agent-based models, DAGs, propositions? Regardless: we need a shared medium to exchange and improve ideas. That medium is FAIR theory: Findable, Accessible, Interoperable, Reusable doi.org/10.1177/1745...

To Be FAIR: Theory Specification Needs an Update - Caspar J. Van Lissa, Aaron Peikert, Maximilian S. Ernst, Noah N. N. van Dongen, Felix D. Schönbrodt, Andreas M. Brandmaier, 2026

Open science innovations have focused on rigorous theory testing, yet methods for specifying, sharing, and iteratively improving theories remain underdeveloped....

Open source software is powerful, but only if people know how to use it. After publishing 12 R packages, I'm shifting toward open educational materials with monthly deep-dive videos on data science in R. First up: mixed data (continuous/categorical) Latent Class Analysis with tidySEM! What's next?

Latent Class Analysis with Continuous and Ordinal Indicators in R

Over christmas, I added tidySEM much-requested support for mixed-data latent class analysis (continuous/categorical)! This was technically possible, but the new implementation is easier, faster, with better convergence! Try it by running remotes::install_github("cjvanlissa/tidySEM"); ?mx_mixed_lca

Fantastic projects awarded, including two I'm part of: Hannes Datta's "ReproHub", which integrates reproducibility/checks into research infrastructure, and Terrence Jorgensen's "Infra-Structural Equation Modelling", which develops lavaan and related open educational material! Congratulations to all!

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!?

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
