In response to the issue of fake news having recently received wide attention and stimulated intense global concern, several leading online and social media platforms have partnered with third-party fact-checking organizations to flag news content and evaluate its accuracy. However, increasing controversy exists regarding the impact and efficacy of fact-checking and the existence of an associated backfire effect. This study systematically examines the research on information correction and the backfire effect, identifies the possible impacts of fact-checking, and discusses the current practice of third-party fact-checking mechanisms in the U.S. Through analysis of secondary data and textual analysis, this study concludes that the current operating principles of fact-checking and the presentation of the results of such fact-checking in the U.S. correspond partly to the research findings regarding the backfire effect. More research is needed to further evaluate the practice and strategies of fact-checking to enhance the positive impact of information correction.
