This study investigates whether social media platforms' attempts to combat misinformation—via general warnings or fact-check tags—are effective in reducing user belief.

Methodology: The authors analyze data from the Facebook News Feed, where false stories are tagged with either labels.

Key Findings: Both interventions reduce belief, but effectiveness varies significantly depending on label design and placement context. Fact-check tags show stronger impact when sourced directly by platforms rather than third parties.

Real-World Implications: These findings offer clear guidelines for platform designers aiming to enhance truthfulness online—prioritizing specific labeling strategies based on research outcomes.

👉 Emphasis: Beyond mere tagging, the study quantifies belief reduction effects across diverse scenarios.
