In this talk, I will talk about two recent projects.

First, I will talk about a cross‑platform study where we collected 10 million news‑link posts across seven social media platforms and examined engagement by outlets’ political slant and quality. We find that platforms with more conservative user bases share lower‑quality news on average; the partisan engagement advantage flips by platform (aligned content wins); and within users, lower‑quality links get higher average engagement—even on non‑ranked feeds—implicating user preferences rather than algorithms.

Next, I will talk about an experimental project that combines lab and field to debunk false claims using LLMs. We tune conversational corrections in a simulated feed, then deploy the best strategies on Bluesky and X to test external validity with native engagement metrics.

The seminar will be hybrid, and online attendance will be available via Zoom.
