Our new article in @science.org enables social media reranking outside of platforms' walled gardens.
We add an LLM-powered reranking of highly polarizing political content into N=1256 participants' feeds. Downranking cools tensions with the opposite party—but upranking inflames them.

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.

What does coordinated inauthentic behavior look like on TikTok?
We introduce a new framework for detecting coordination in video-first platforms, uncovering influence campaigns using synthetic voices, split-screen tactics, and cross-account duplication.

We constantly ask our apps where to visit, eat or drink.
AI tells us, and most of the time, we follow it. The loop continues.
But do AIs favor certain places? How would we even know if we don’t own the platforms?
We modeled this complex phenomenon, and results are fascinating!

The three horsemen of social media: brain rot, anxiety and foreign interference
With so many media institutions bidding farewell to X, it's a good time to reflect on the relationship status of social media and European society at large.
