📣 Work with me on AI and behavioral science. I am hiring an Assistant Professor (3 years) at WU Vienna, in collaboration with my team at the MPI for Human Development. Start Jan 2027 or by arrangement. Deadline Nov 11. Please share. jobs.wu.ac.at/Assistant-Pr...

📣 Delighted to share that I have joined WU (Vienna University of Economics and Business) as Professor of Artificial Intelligence and Behavioral Science. Announcements for at least one postdoc-level position will follow soon. Please reach out if you are interested.

Women still exit psychological research at a disproportionate rate. Tracking 80k researchers, our new article maps the gender attrition gap and shows that differences in performance, networks, and institutions explain only part of it. psycnet.apa.org/doi/10.1037/... arxiv.org/abs/2510.13273

🚨 New preprint Excited to share new work led by Raluca Rilla, showing how cheap, open agents threaten online data collection and how open-text analysis beyond conventional traps can help mitigate this threat. 🔗 arxiv.org/abs/2609.31054 With @Anne-Marie Nussberger and @ruimata.bsky.social .

New paper out in @pnas.org 🚨 Human learning is an understudied but promising lever for boosting human–AI synergy @jasonburton.bsky.social @ralfkurvers.bsky.social @stefanherzog.bsky.social @dirkwulff.bsky.social

Very proud of @kirikuroda.bsky.social for preprinting this study on social influence and information cascades in experienced based decision making. osf.io/preprints/ps... @arc-mpib.bsky.social. Great collab with @simyciri.bsky.social @dirkwulff.bsky.social

🚨 Out now in TICS How can language models help cognitive science? @ruimata.bsky.social & I outline 5 uses: mapping research fields, formalizing theories, cleaning up constructs & measures, predicting behavior across tasks, and capturing environmental variation. 🔗 doi.org/10.1016/j.ti...

🚨 Now out in PNAS In decision research, "talk is cheap." We show it isn't. Using LLMs to analyze participants' free-text explanations of their choices, we find verbal reports are a rich, scalable window into how people actually decide. 🔗 www.pnas.org/doi/10.1073/... Led by Kamil Fulawka

📣 Reporting checklist for LLMs in behavioral and social science New article presenting a consensus-based reporting checklist (GUIDE-LLM) for the use of LLMs in the behavioral and social sciences to foster transparency, reproducibility, and ethical use. 🔗 www.nature.com/articles/s41...

🚨 New preprint 🚨 Excited to share a new preprint led by @zakashussain.bsky.social. We review how large language models compare to humans in behavior and representations. Our conclusion: LLM cognition is not simply human-like or non-human-like. It is jagged. 🔗 Preprint: osf.io/preprints/ps...

🚨 Updated preprint 🚨 Excited to share this updated preprint, in which @ruimata.bsky.social and I discuss five ways LLMs can help address longstanding challenges in cognitive science and psychology, examining both opportunities and pitfalls. 🔗 arxiv.org/abs/2511.00206

🚨 New publication 🚨 Excited to share this new forum piece led by @kevinetiede.bsky.social We propose broadening risk communication to cover neglected dimensions outlined in our risk-information taxonomy, requiring greater reliance on simulated experiences. Open access: doi.org/10.1016/j.ti...

WORKSHOP ON BEHAVIORAL CLONES Imitating humans is a powerful route to machine behavior, an emerging lens on human cognition, and a prerequisite for social simulation. 🗓 Fri 20 May 26 Following Machine+Behavior @ Max Planck Berlin Invited talks by @danicajdillion.bsky.social @marcelbinz.bsky.social

🚨 New preprint 🚨 We present the decisions-from-experience database (DfE-DB), including data from 168 studies. The data are currently shared with the original authors and made public upon publication. 🔗 Database: github.com/dwulff/dfe-db 🔗 Preprint: www.biorxiv.org/content/10.6...

I am hiring a postdoc for a DFF-funded project on social influence, and the decision processes that fuel rich-get-richer dynamics in the online/offline world. The position is for up to a year, competitive Danish salary, remote work possible. Interested or know somebody? DM me or share!

🔬 How has psychology contributed to achieving the 🇺🇳 SDGs? Our new preprint maps 230,000 psychology articles to the SDGs using our text2sdg R package (www.text2sdg.io) and analyzes historical trends in topics, national and gendered contributions, and citation patterns. 🔗 arxiv.org/abs/2512.08628

@cos.io, I noticed that, since the relaunch, PsyArXiv preprints are no longer being indexed by Google Scholar. Do you know if this will be fixed? Thank you for your work!

How can LLMs advance the cognitive sciences? @ruimata.bsky.social and I put together a review on how LLMs can help us address five long-standing problems in cognitive science (e.g., disciplinary silos or lack of generalizability). 🔗 arxiv.org/2511.00206

🚨 New preprint - Advancing Cognitive Science with LLMs Excited to share this new preprint together with Rui Mata. We review how 🤖 LLMs can help address long-standing problems in cognitive science, highlighting opportunities and pitfalls. 🔗 Preprint: arxiv.org/abs/2511.00206
