1. Evidence of interconnectedness -- Cross-platform community structure, narrative patterns, and discourse network proximity as a predictor of narrative adoption (across and within platform boundaries).
2. The role of smaller platforms -- Even platforms with relatively small userbases play meaningful roles in narrative propagation, particularly in fringe-to-mainstream flow.
3. Causal evidence & policy implications -- Counterfactual simulations quantifying the structural importance of different platform classes, and what that means for governance.
Patrick Gerard will present this Thursday (6/4 1:00pm-2:00pm ET; see blurb below).
Best regards,
Antonio

I'll be sharing work on the 2024 U.S. election information ecosystem across 13+ platforms. The central finding is that the ecosystem is deeply interconnected across platform boundaries in ways that have real consequences for how narratives spread. The presentation has three major aspects:
1. Evidence of interconnectedness -- Cross-platform community structure, narrative patterns, and discourse network proximity as a predictor of narrative adoption (across and within platform boundaries).
2. The role of smaller platforms -- Even platforms with relatively small userbases play meaningful roles in narrative propagation, particularly in fringe-to-mainstream flow.
