💥 Our new paper (with Lucas Molleman and Björn Lindström) is now out in @NatureHumBehav 🥳 nature.com/articles/s41562-0… 🧠 Here, we advance a novel RL account—the Social Feature Learning (SFL) model—that explains how people learn to learn from others! 🤝 🧵👇

🎊 New paper out! In this @TrendsCognSci Forum, we (with Lucas Molleman and Björn Lindström) summarize how reward learning can lead to adaptive social learning. We also explore the broader consequences for cultural evolution: cell.com/trends/cognitive-sc…

Reward is enough for social learning

Adaptive behaviour relies on selective social learning, yet the mechanisms underlying this capacity remain debated. A new account demonstrates that key strategies can emerge through reward-based...

Going beyond these experiments, we explore the implications of the SFL model for social learning under a variety of environmental contexts (such as spatial & environmental variability or dangerous environments, check out the full paper for these agent-based simulations and more)

Altogether, we present a mechanistic account for the substantial flexibility and variability in social learning. A domain-general reward learning model shows that personal experience shapes social learning to render it adaptive Thanks to the reviewers and editorial team! 💐

This research advances a mechanistic reward learning account of social learning strategies. Through experiments & simulations, it shows how people learn to learn from others, dynamically shaping the processes involved in cultural evolution. @DSchultner nature.com/articles/s41562-0…

🚨 New preprint out! 🚨 How do people make moral judgments as third parties? 👀 We show how two motivations—inequality aversion (fair = moral) ⚖️ and the common-is-moral heuristic (frequent = moral) 👨‍👩‍👧‍👧—interact to shape evaluations 🧵👇 📄 osf.io/preprints/psyarxiv/na…

Inequality Aversion and the Common-is-Moral Heuristic shape Third-party Morality

Moral norms regulate social life in ways that can promote prosocial behavior. Not only directly involved individuals, but also uninvolved third parties judge and punish norm violators. The principles...

Together, these findings show that fairness concerns & conformity jointly but independently shape moral norms. Understanding their interplay can help explain the successes & failures of third-party judgments regulating prosociality in social systems

A fantastic blog post on our recent PNAS paper! It elegantly describes our rather complex findings and discusses their implications for bias reduction. I love the AI-generated podcast version, too. Thanks to @thepeoplegeek.bsky.social! davehodges.substack.com/p/th…

🌻 New paper out in @PNASNews! We employ a reinforcement learning approach to understand how societal stereotypes are internalised as personal prejudice. link: pnas.org/doi/10.1073/pnas.24… @david_m_amodio's excellent explainer 🧵 below:

🚨New in @PNASNews, led by @DSchultner & Ben Stillerman: In 8 studies, we test a mechanism through which exposure to societal stereotypes—even those we know may be false—can implicitly transform into individual-level prejudice and then spread across a community.

This research is in conversation with our other work on observational learning of prejudice: science.org/doi/10.1126/scia…

Transmission of social bias through observational learning

Viewing a prejudiced person’s intergroup behavior induces that bias in observers, revealing a mechanism of bias propagation.
