They double-booked a room for the "Healthy, Wise, Wealthy, Decision Making" and "Moral Machines" sessions at SPSP, but @williambrady.bsky.social exercised some masterful (& healthy & wise & moral & wealthy?) negotiation skills and we're now getting two sessions of talks in one 😊

@killianmcloughlin.bsky.social social media news especially likely to use villian / victim framing; low quality news especially; more likely to evoke outrage and draw engagement when doing so #spsp

Many think LLM-simulated participants can transform behavioral science. But there's been a lack of accessible discussion of what it means to validate LLMs for behavioral scientists. Under what conditions can we trust LLMs to learn about human parameters? Our paper maps the validation landscape.

Last year at SPSP we had some great discussions about research with LLMs. This time #spsp2026 we're back with a whole workshop!
Friday 2/27 at 8am, + informal drinks at 6pm to continue the conversation
More info, plus a chance to submit discussion topics, here:

Interested in why moral conflict is so common on social media?
Join us at #SPSP 2026 for our symposium. We’ll present new findings on how platforms shape digital discourse and explore pathways toward healthier online environments
🗓 Saturday, the 28th | 9:30–10:40 AM
📍 Room E270, Level 2

Before the end of this year, I’m glad to share a short perspective/policy piece, recently out with @joshcjackson.bsky.social , Zhao Wang, and @williambrady.bsky.social: “Large AI Models Have a Prioritization Problem: Policy Implications and Solutions.”

Abstract When we empathize with someone going through something, we often draw on our past experiences with the someone and the something. These kinds of experiences ground "thick empathy", a form of empathy that has been largely overlooked in the psychology and neuroscience literature. Consider how a mother, empathizing with her daughter about to give birth, can draw on her own experience of childbirth, and her relationship with her daughter, to deeply grasp what her daughter is going through in a way that others who lack those experiences cannot. I argue that thick empathy deserves more empirical attention because it is associated with well-being and helps us build networks of effective mutual social support. My analysis highlights novel risks and dilemmas posed by "empathy machines" that promise to enhance or even replace human empathy and are becoming increasingly popular as a potential solution to widespread loneliness. Even when empathy machines provide value to individuals, their widespread adoption risks imposing collective emotional and epistemic costs that ultimately make it harder for us to empathize well. Keywords: empathy, understanding, experience, thick description, ethnography, phenomenal knowledge, interpersonal knowledge, virtual reality, artificial intelligence, chatbots

It is perhaps foolhardy to attempt to say something new about a topic as widely studied as empathy. I tried anyway! 1/
New from me - how AI-generated political videos have become just another part of social media, used to entertain, outrage and monitize attention

Out now in Scientific Reports! Despite high correlations, ChatGPT models failed to replicate human moral judgments. We propose tests beyond correlation to compare LLM data and human data.

So there you have it, twin study estimates were greatly inflated, and molecular data sets the record straight. I walk through possible counter-arguments, but ultimately the uncomfortable truth is that genes contribute to traits much less than we always thought.

Great work by @natematias.bsky.social & Megan Price: public involvement in AI is an important part of rigorous science. AI systems are sociotechnical, meaning that the lived experience of the public is essential for validation, etc.

New preprint out 📄
“Why Reform Stalls: Justifications of Force Are Linked to Lower Outrage and Reform Support.”
Why do some cases of police violence spark reform while others fade? We look at how people explain them—through justification or outrage.

Examining news on 7 platforms:
1)Right-leaning platforms=lower quality news
2)Echo-platforms: Right-leaning news gets more engagement on right-leaning platforms, vice-versa for left-leaning
3)Low-quality news gets more engagement EVERYWHERE - even BlueSky!

Humans are imperfect decision-makers, and autonomous systems should understand how we deviate from idealized rationality
Our paper aims to address this! 👀🧠✨

They also show we might be able to people more receptive to political dialogue with a political opponent even when outrage is clearly expressed against people’s own political views.
11.11.2025 16:34 — 👍 1 🔁 0 💬 1 📌 0These results help solve a puzzle (cc @steverathje.bsky.social). Why do people express outrage when reporting they don't want to see it in their feeds? We suggest because when they express it they typically have behavioral motives, but they think others have contra-hedonic motives!
