    New paper in Science: In a platform-independent field experiment, we show that reranking content expressing antidemocratic attitudes and partisan animosity in social media feeds alters affective polarization. 🧵
    Today, social media platforms hold the sole power to study the effects of feed-ranking algorithms. We developed a platform-independent method that reranks participants’ feeds in real time and used this method to conduct a preregistered 10-day field experiment with 1256 participants on X during the 2024 US presidential campaign. Our experiment used a large language model to rerank posts that expressed antidemocratic attitudes and partisan animosity (AAPA). Decreasing or increasing AAPA exposure shifted out-party partisan animosity by more than 2 points on a 100-point feeling thermometer, with no detectable differences across party lines, providing causal evidence that exposure to AAPA content alters affective polarization. This work establishes a method to study feed algorithms without requiring platform cooperation, enabling independent evaluation of ranking interventions in naturalistic settings.

    [Please RT] I’m recruiting PhD students to start Fall’23 at @UW! I’m looking for students passionate about using computational methods to study how social platforms can be reimagined to enable better conversations, bridge political divides, and reduce the spread of misinfo. >>

    Being on the job market was stressful (ppl were right) but also (surprisingly) fun. It was a pleasure to interact with so many amazing people along the way. Huge thanks to my mentors and collaborators for their support, especially @jugander, @dkroy, @ladamic, and @deaneckles.

    Very excited to see my officemate's (@CrashTheMod3) excellent work on the cover of Science! False news spread farther, faster, deeper, and more broadly than the truth news.
