Political Ideology, Ingroup Favoritism, and Conspiratorial Thinking: Patriotism, Nationalism, and COVID-19 Conspiracy Theories.

This article examined the relationship between ideology and conspiratorial thinking and the related mediating effect of ingroup favoritism in a non-Western society. We investigated patriotism and nationalism as two favorable orientations toward national ingroups. We also examined their relationship with the general conspiracy mentality and the specific conspiracy beliefs that have emerged during the COVID-19 pandemic. The results revealed that conservative ideology was associated with conspiratorial beliefs in China regardless of the specific conspiracy theories related to ingroups or outgroups, which indicates such tendencies may exist universally across cultures. Patriotism was not associated with conspiracy theories about the origin of COVID-19, whereas nationalism was negatively associated with the conspiracy theories about China (an ingroup) and positively associated with conspiracy theories about the US (an outgroup). Moreover, nationalism mediated the relationship between ideology and specific conspiracy beliefs during the pandemic. The general conspiracy mentality did not predict conspiracy theories about the origin of COVID-19. The results indicate that believing conspiracy theories is not only the result of a stable conspiracy mentality but is also influenced by ideology and intergroup relations.
