There are many moral setbacks in the world: wars, violence, harmful policies. Yet, many of us still try to create change. Why? Now out in Cognitive Science, with Tania Lombrozo and Sana Asifriyaz! doi.org/10.1111/cogs.7…


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

Join us tomorrow, for a presentation of our work (with Maximilian Maier 🔍, Vanessa Cheung , Fiery Cushman, Falk Lieder) on disentangling model-based and model-free moral Learning. Paper: escholarship.org/uc/item/8p05c2…


People in rich countries often underestimate how wealthy they are globally. A new study finds that a simple nudge correcting this misperception increases generosity. Research by Glen Spiteri, Maximilian Maier 🔍, Harry Coulson, & Falk Lieder: escholarship.org/uc/item/0wm7t7…


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…
