My department is hiring. It's a rare department that prides itself on massive interdisciplinarity. Our students are all graduate students, typically mid-career military officers, currently ~30% international.

In 2023 we showed how engagement-based algorithms exploit human social learning biases, distorting how we learn what's normal, common, or credible from each other ("Algorithm-mediated social learning," Trends in Cognitive Sciences). The obvious follow-up: where does generative AI fit in?

In this new paper w/ @joshcjackson.bsky.social , @nickornstein.bsky.social , @felix-chenwei.bsky.social , & Bolun Sun, we argue generative AI also distorts social learning, but because it optimizes for something different, it distorts in a different direction.

I'm not sure I'll ever collaborate on a project cooler than this one -- huge props to Billy (@williambrady.bsky.social) for his fearless leadership from start to finish! And how cool is this!?: This paper is Nature's first-ever published Stage 2 Registered Report. 🔥

✨New paper out @nature.com ✨ For 8 weeks around the 2024 US election, we randomly assigned 2,000 people to use social media algos we built ourselves. Do engagement-based algorithms amplify intergroup, moral & emotional (IME) content—and does that distort how we see political norms? 🧵🔗 👇
