🚨New preprint!🚨Excited to share my 1st PhD project with Bonan Zhao / 赵博囡 Griffiths Computational Cognitive Science Lab Natalia Vélez (natvelali.bsky.social @ 🦋) Teaching is a powerful way to pass on "tools for thought" to solve new problems. How well do existing teaching models of teaching capture this process? Link: osf.io/preprints/psya…

🚨 Job alert 🚨 One more week to apply for two positions (PhD and Postdoc) at Center for Adaptive Rationality (MPIB, Berlin) and Max Planck Institute for Human Development on using LLMs to improve generalizability in the behavioral and social sciences LLMs. The positions are fully funded for three years. Apply by October 13! Thank you for

New Psychology Today post: "Failure to Replicate the Identified Victim Effect: We may need to rethink and reframe charitable-giving biases" Read: buff.ly/40jYoqA by Rajarshi Majumder, who led the project to a publication in JDM. Preprint: osf.io/ybz2a

Our paper on "Model-Averaged Bayesian t tests" is now published in Psychonomic Bulletin and Review doi.org/10.3758/s13423… Tutorial video available at: youtube.com/watch?v=EcuzGT… Summary of the paper below👇

For anyone who is still here, I am planning to mostly post on the other place from now on!

We updated this preprint (osf.io/preprints/psya…) with a new study investigating sources of this yes-no framing bias and amplified omission bias in LLM moral decision-making. Results suggest that they likely arise from fine-tuning for chatbot applications. Maximilian Maier 🔍 Falk Lieder

There is a major improvement to the RoBMA package. Model structure and parameters can be estimated within a single MCMC yielding a tremendous speedup! A Bayesian publication bias model-averaged meta-regression can be estimated in less than a minute now! (down from 30min)

New preprint w/ Maximilian Maier 🔍, Harry Coulson & 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 preprint w/ Maximilian Maier 🔍, Vanessa Cheung, Fiery Cushman, & Falk Lieder: Disentangling Model-Based and Model-Free Moral Learning doi.org/10.31234/osf.i… Excited to present this work at #CogSci2025!

Excited to share that our paper is now published in PNAS! pnas.org/doi/10.1073/pn…

In this article, Maier et al. show that metacognitive learning from consequences can shape moral decision-making. Maximilian Maier 🔍 Vanessa Cheung Falk Lieder The Rational Altruism Lab nature.com/articles/s4156…
