Extreme stances about AI and LLMs in particular (be them deflationary or inflationary) are very likely wrong, valid and certainly not good for an healthy debate. But where do they come from? We (with @giadapistilli.com) argue that common cognitive biases may play a role: osf.io/preprints/ps...

PNAS is explicit that “The purpose of peer review is not to demonstrate the reviewer’s proficiency in identifying flaws” Is this your skill set? Review for us at @error.reviews instead where this explicitly is the necessary skill set. error.reviews www.pnas.org/reviewer

How can we reduce conceptual clutter in the psychological sciences? @ruimata.bsky.social and I propose a solution based on a fine-tuned 🤖 LLM (bit.ly/mpnet-pers) and test it for 🎭 personality psychology. The paper is finally out in @natrevpsych.bsky.social: go.nature.com/4bEaaja

Excited to share the materials for our course on open LLMs for science of science research @zakashussain.bsky.social and I offered at the recent meeting of @euroscisci.bsky.social at @lmumuenchen.bsky.social. github.com/zak-Hussain/...

Do LLMs think? Excited to share our updated preprint critically discussing two "Justaic" stances claiming that LLMs lack cognition because they are "just" next-token predictors or "just" machines. Led by @zakashussain.bsky.social and with @ruimata.bsky.social . osf.io/preprints/os...

🚨 Applications for the 22nd Summer Institute on Bounded Rationality are now open! 🌐 Join us in Berlin @mpib-berlin.bsky.social from June 17–25, 2025 to explore "Decision Making in a Digital World". ✏️ Application deadline is March 9 - more info at 👇!! www.mpib-berlin.mpg.de/research/res...

In our latest article, published in @pnas.org and led by @marcelbinz.bsky.social and Stephan Alaniz, we got together four diverse groups of scientists to reflect on how LLMs should affect science. From treating them like co-authors to using other tools instead, many interesting arguments emerged.

The potential of LLMs in social & behavioral science is enormous—but how can we leverage them? Zak Hussain & I just taught a 5-day course at #GSERM Ljubljana on this. Check out our open materials (cc-by-sa) on using open LLMs with @hf.co. github.com/Zak-Hussain/...
