Now out in Behavior Research Methods! With @maxmaier.bsky.social & Falk Lieder, we developed the 12-item Decision Process Scale, which measures how much people rely on rules vs. cost-benefit reasoning and intuition vs. deliberation in individual dilemmas. link.springer.com/article/10.3...

I was just trying to download some replication files from Management Science and came across this highly unusual policy! This seems very problematic as it would allow the journal to reject any work scrutinising the paper completely at their discretion, without possibility of submitting elsewhere.

Today's HotFresh recommended paper is: Maier, M., Harris, A. J. L., Kellen, D., & Singmann, H. (2025). Decision making under extinction risk. Cognitive Psychology, 159. doi.org/10.1016/j.co...

I am recruiting (Canadian🇨🇦) graduate students at York University for Fall 2026 in Social and Personality Psychology! If you are interested in misinformation, political polarization, and/or computational social science, I'd love to hear from you. Feel free to reach out with any questions.

Exciting #rstats news for Bayesian model comparison: bridgesampling is finally ready to support cmdstanr, see screenshot. Help us by installing the development version of bridgesampling and letting us know if it works for your model(s): pak::pkg_install("quentingronau/bridgesampling#44")

How do people choose between moral rules or cost-benefit moral reasoning when faced with dilemmas? Research by @maxmaier.bsky.social et al suggests metacognitive learning from *consequences* shapes moral decision-making, which is surprisingly malleable: buff.ly/6SREXa0

Our new research paper is out in NHB, which we apparently coauthored with acclaimed actor Ryan Reynolds. Critics are calling it his best work since Deadpool.

For all those at #CogSci2025, @glenspiteri.bsky.social will be presenting this work at 14:15 PDT (22:15 BST for those online and UK based)! “Communicating Global Income Rank Increases Charitable Donations” Session: ‘Talks 8: Social Cognition’ @cogscisociety.bsky.social

@fbartos.bsky.social @maxmaier.bsky.social‬ & EJ Wagenmakers have extended RoBMA with 3-level publication bias-adjusted model-averaged meta-regression models in R along with the usual code-free and intuitive @jaspstats.bsky.social implementation. Nerdy details are osf.io/preprints/ps...

In Deutschland wird leidenschaftlich über mögliche Änderungen an den Strukturen der wissenschaftlichen Zusammenarbeit diskutiert. Das Ziel ist, die vielfältigen Verführungen zum Machtmissbrauch, die das gegenwärtige deutsche System beinhaltet, stärker zu beschränken.

Happy to share that I passed my viva yesterday without corrections and will start as Assistant Professor at Warwick Business School on 1st of August - I look forward to the next chapter at Warwick and to building new collaborations with the exceptional colleagues there!

Out in Cognitive Psychology, led by @maxmaier.bsky.social: www.sciencedirect.com/science/arti... A new lottery task with choices that matter across trials; the risky option has a chance of going extinct, which ends the study. We derive optimal policies and develop a strategy-classification model.

Excited to share that this paper is now published in PNAS! (With @maxmaier.bsky.social & Falk Lieder) www.pnas.org/doi/10.1073/...

New preprint w/ @glenspiteri.bsky.social , @maxmaier.bsky.social & Falk Lieder: Telling people their global income rank (RBN) increased charitable donations. Also explored RBN’s effect on perceived global income distribution + whether asking how much others should donate increased giving (IDT) 🧵…

New paper with Tong Liu and Arndt Broeder, just accepted in Cognition. We test novel qualitative predictions from sampling-based models of probability estimation in an event ranking task. Results provide evidence for the idea that mental sampling underlies probability judgements.

First time on Blue Sky! Super happy this article is now out in an issue of Political Psychology! And honoured by the promo tweet with custom-made graphic! @leede-wit.bsky.social

Dave Lagnado is looking for a post doc to work on causal inference! The BR-UK team is doing some very cool stuff, so if you're currently looking for a job, check this out: www.ucl.ac.uk/work-at-ucl/...

New preprint "Decision Making Under Extinction Risk" with Adam Harris, David Kellen, and @singmann.bsky.social. osf.io/preprints/ps...

We updated our preprint on moral decision-making in LLMs (osf.io/preprints/ps...) with a new study investigating sources of the yes-no framing bias and amplified omission bias. Results show that they likely arise from fine-tuning for chatbot applications. (w/ @maxmaier.bsky.social and Falk Lieder)

(1/5) Very excited to announce the publication of Bayesian Models of Cognition: Reverse Engineering the Mind. More than a decade in the making, it's a big (600+ pages) beautiful book covering both the basics and recent work: mitpress.mit.edu/978026204941...

New paper "Model-Averaged Bayesian t tests" in Psychonomic Bulletin and Review with Frantisek Bartos, @dsquintana.bsky.social, Fabian Dablander, Don van den Bergh, @maartenmarsman.bsky.social, Alexander Ly, & @ejwagenmakers.bsky.social Paper: doi.org/10.3758/s134... Tutorial video & summary below👇
