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 doi.org/10.1016/j.co...

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."

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."

"You can’t reboot the planet if you crash it" | My commentary on Bill Gates' flawed new climate missive for @thebulletin.org: thebulletin.org/2025/10/you-...

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.

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. 1/n

If you’re in #Munich 🥨 and curious about decision-making, perception, and cognition through a translational lens, join us for a seminar I’m hosting on Oct 30 with three fantastic speakers: @jkesby.bsky.social (visiting from 🇦🇺), @miguelbengala.bsky.social, and @jacob-lab.bsky.social 🧠💡

you heard of running Doom on random gadgets but have you ever heard of… “Hosting a WebSite on a Disposable Vape” bogdanthegeek.github.io/blog/project... this explains how! ((the internet is healing 😌)) #IndieDev

Just back from this - I was the misfit invited speaker who knows nothing about psychology. It was really educational for me, expanded my view of theory construction problems in the human sciences.

A nice shift in perceived colour between central and peripheral vision. The fixated disc looks purple while the others look blue. The effect presumably comes from the absence of S-cones in the fovea. From Hinnerk Schulz-Hildebrandt: arxiv.org/pdf/2509.115...

Excited to share joint work with Ulf Hahnel and @sgluth.bsky.social on investigating how attribute translations - a widely implemented behavior intervention - lead to more ecological consumer choices. Main results are below, but check out our preprint 👇 www.researchsquare.com/article/rs-7...

For all who use Bayesian hierarchical models, have a look at our new preprint, out now together with @linushof.bsky.social @nunobusch.bsky.social and @thorstenpachur.bsky.social osf.io/preprints/ps...

We know that a consensus of opinions is persuasive, but how reliable is this effect across people and types of consensus, and are there any kinds of claims where people care less about what other people think? This is what we tested in our new(ish) paper in @psychscience.bsky.social

We ran a randomized controlled trial to see how much AI coding tools speed up experienced open-source developers. The results surprised us: Developers thought they were 20% faster with AI tools, but they were actually 19% slower when they had access to AI than when they didn't.

Congratulations to @linushof.bsky.social from our lab @tum.de for being the runner-up at this year’s #teap2025 poster competition! His research shows that people search adaptively in decisions from experience.

The short paper on the statConfR package together with Sascha Meyen and @sehellmann.bsky.social has now been published. Reviews in JOSS are not only about the paper but also the code, which I think is a great idea, especially for cognitive modelling.

StatConfR v. 0.2.0 for static models of decision confidence and measures of metacognitive efficiency is now available on CRAN. Thanks to Sascha Meyen, the package now includes information-theoretic measures of #metacognition. Also, the package can now be used to visualize model fits.

Serial dependence of confidence judgments reveals metacognitive adaptation: http://osf.io/f35br_v1/

New from my lab: "Priors for natural image statistics inform confidence in perceptual decisions" We used a natural image statistics approach to investigate the computations underlying perceptual confidence. 🧵 Article: www.sciencedirect.com/science/arti...

Why does it feel good to be sure? In new work @voalan.bsky.social @andero.bsky.social and I bridge confidence and affect. In perceptual DM, we found a remarkably consistent association between both measures! ↓↓↓ link: www.tandfonline.com/doi/full/10.... #PsychSciSky #Neuroscience #Neuroskyence

Fresh out: a short review article where I give an overview of different ways that across-trial temporal structure is helpful in understanding cognitive models of decision-making osf.io/preprints/ps...

In a new study, we show that while metacognitive confidence is domain-general, updating self-beliefs is highly domain-specific across memory, vision, and semantic knowledge. Our findings illuminate how metacognitive experiences refine self-assessments. #psych 🧪 www.sciencedirect.com/science/arti...

Thanks for teaching me so much @manurausch.bsky.social !

New preprint together with @manurausch.bsky.social about the importance to consider decision time when reflecting on the accuracy of a decision, showing that considering decision time in confidence is Bayes optimal and human observers seem to make use of this information. osf.io/preprints/ps...
