Various conspiracy theories have accompanied COVID-19 since its initial outbreak. Based on a nationwide survey in China, this study probes the health consequences of beliefs in different COVID-19 conspiracy theories in China. The research found that believing the coronavirus has a foreign natural origin was associated with increased rather than decreased intention to adopt protective behaviors. Nonetheless, believing that the source of the pandemic was a Chinese lab or that it is a foreign biological weapon was related to reduced intentions to protect one's health. In addition, measured as national pride and satisfaction with China's pandemic control effort, people's level of nationalism was strongly associated with their intention to adopt protective behaviors, which moderates the health consequences of believing in false conspiracy theories. Scientific literacy was also associated with an increased likelihood of adopting preventive measures. Despite revealing the diversified health consequences of conspiracy beliefs, this study demonstrates the importance of examining collectivist sociopolitical constructs in health communication.
