AI Summary

This study investigates how individual versus collective misinformation labeling mechanisms affect information diversity and cross-community diffusion on Twitter (X). Using real-world platform data, we construct a causal inference framework integrating event study methodology, information entropy–based diversity metrics, and network mobility modeling to empirically disentangle the distinct sociotechnical effects of these two labeling paradigms. Results demonstrate that collective labeling significantly enhances users’ exposure diversity (+27%) and cross-community information flow (+41%), exhibiting a nonlinear amplification effect; in contrast, individual labeling yields negligible and statistically unstable effects. Our findings reveal the pivotal role of coordinated, community-driven annotation in fostering heterogeneous information ecosystems. By providing mechanistic evidence on how labeling design influences structural properties of information diffusion, this work advances platform governance theory and offers concrete, evidence-based design principles for content moderation systems.
