Who endorses conspiracy theories? A moderated mediation model of Chinese and international social media use, media skepticism, need for cognition, and COVID-19 conspiracy theory endorsement in China

Abstract

During the COVID-19 pandemic, various conspiracy theories have been circulating through social media platforms Scholars have raised concerns about the negative ramifications of conspiracy theories, such as the deterrence of preventive measures Against this backdrop, the current study analyzed an online survey (N = 731) from China and examined the conditional indirect effects of Chinese and international social media use on conspiracy theory endorsement (CTE) regarding COVID-19 Findings showed that Chinese social media use was not associated with CTE, while international social media use was negatively associated with CTE Moreover, the significant association was mediated by media skepticism Further, individuals’ level of need for cognition (NFC) was found to moderate the indirect effect That is, among people with higher levels of NFC, the negative indirect effect of international social media use on CTE became stronger Theoretical and practical implications were discussed
