User Correction.

This paper reviews the existing literature on user correction to consider its value for combating misinformation on social media. We discuss the effectiveness of user correction in reducing misperceptions, and synthesize best practices, highlighting the dual audiences for public correction on social media. We outline how often user correction occurs across contexts, countries, and social media platforms. We pay special attention to the methodological constraints in existing research, emphasizing the need for using diverse and interdisciplinary methods, including longitudinal surveys and experiments, computational methods, realistic simulated environments, and qualitative methods. We call for a more comprehensive understanding of user correction in terms of its long-term and downstream effects on social media platforms.
