I want diplomats recalled from the US. I want renegotiations about US bases in Europe. I want an official boycott of the World Cup by all participating nations. I want new articles of impeachment filed every single day.
Play time is over. Act like adults or make way for those who do.
cover of the book "Bayesian Workflow" by Gelman, Vehtari, et al. Coming out later this year, in the summer probably.
I would have preferred to have the "draw the rest of the owl" meme on the cover, but this will do. Seems like it is on schedule, and we'll leave some typos so you know we didn't write it with AI.
I am thrilled to announce the European Summer School on Eye Movements! #ESSEM2026 takes place 7-12 September, 2026, at the Institute of Psychiatry, Psychology & Neuroscience, King’s College London. Further details including info on how to register can be found here: essem2026.org
A viral dog rescue from 2016 is now immortalized with a statue in Kazakhstan. When a dog fell into the Sayran reservoir, bystanders formed a human chain to pull him to safety. The statue is a reminder of the value of unity, solidarity and collective action. 14/10 for all
How do people search for information to make efficient decisions?
Our new theory, now out in Psychological Review, suggests that an efficient search rule is (at the core of) the answer. And eye-tracking data support our theory.

@teap2026.bsky.social is over: 4 days, 10 workshops, 1 public lecture by @jensfoell.de, 3 keynotes, 80 talk sessions, and 3 poster sessions 👍🏼 Co-organizing this international experimental-psychology conference with Franziska Rück and Barbara Kaup, we brought over 700 researchers to Tübingen 😊
Curious about how context influences decision-making? 👀🧠
Make sure to check out our symposium on Wednesday 11:00-12:30 at Room N2 #TeaP2026

I tracked every keyword in 22 years of Cosyne abstracts to map how computational neuroscience evolved — from Bayesian brains to neural manifolds to LLMs — and where it's heading next.
Our new paper is out in Cognition! What determines whether confidence follows the classic "folded-X" pattern vs. the "double-increase" pattern? The answer lies in the type of stimulus manipulation. Big thanks to my advisor Doby @dobyrahnev.bsky.social and co-first author @herrickfung.bsky.social !
Yesterday, we finally got to celebrate the successful PhD defense of our PostDoc @maryamtohidi.bsky.social at a delicious Iranian restaurant😋
We are so proud of Dr Tohidimoghaddam, who continues her journey with us elucidating multi-attribute decision-making🧠 Stay tuned for her future contributions!
'If you've eliminated a few possibilities and you can't think of any others, your weird theory is proven right' isn't quite as rhetorically compelling.

Compositional data (proportions that sum to 1) behave in ways standard models aren’t built for
I walk through why Dirichlet regression is often the right tool & what extra insight it gives using a real ex of eyetracking

How do priors influence speech processing? Do they enhance expected signals or highlight the unexpected (prediction errors)? @fabianschneider.bsky.social' s work shows: It depends!

New article in Cognitive Psychology with @thorstenpachur.bsky.social and Veronika Zilker: “How sampling strategies shape experience-based risky choice.”
We present a computational framework for information search and choice in decisions from experience. 1/4

Computer scientists: "So with machine learning we can extract subtle patterns from massive datasets. What shall we do with it?"
Business school professors, every single time: "You know, I think phrenology got a raw deal in the late 1800s."
Well this is exciting!

Grüne vollziehen Kehrtwende bei der Homöopathie: Am ersten Tag des Grünen-Parteitags in Hannover wird es lebhaft: Ein Antrag wird angenommen, der die Finanzierung homöopathischer Leistungen durch gesetzliche Krankenkassen untersagen will. Eine historische Kehrtwende.

Wir starten mit der ersten Seite der Doktorarbeit von Paul Langerhans, dem Entdecker der pankreatischen Inseln. Lief wohl alles nicht so rund und ich mag diesen Satz sehr: "Der einzige Zweck dieser Entstehungsgeschichte meiner Arbeit ist Motivierung und Entschuldigung ihres geringen Gehaltes."

Another good reason to kill this whole industry now. It’s going to fail anyway, we may as well do so while we still have a chance to restore the planet.
Kurzgesagt - in a nutshell explains perfectly why AI in such Context is really problematic.
Also John Oliver from Last week tonight did a really good video about AI Slop and how many think it's real.

Congrats to @hashimsat.bsky.social and our amazing collaborators on this great team effort.
Special shout-out to @haukeren.bsky.social, who made this possible through his generous support 🙌
Award-winning pain researcher here. This is not something that can be done. Hope this helps.
Glad to see my first-year project is out!
In two experiments, we manipulated multiple stimulus features in a perception task, yet their effects on confidence and accuracy fell into just two distinct behavioral patterns, offering a way to predict the effects of novel stimulus manipulations.
