Belief in science-related conspiracy theories

Conspiracy theories attempt to explain social phenomena by attributing them to the supposed secret actions of powerful, malevolent groups. Due to their associations with potentially harmful nonnormative behaviours at both the individual and collective levels, researchers have expressed particular concern over conspiracy theories that malign science. To better understand such beliefs, we conducted a national U.S. survey to gauge respondents’ agreement with 11 science-related conspiracy theories and their political, psychological, and social characteristics. We find that beliefs in specific science-related conspiracy theories represent two unique factors that are (i) related to nonnormative behaviours including political violence, vaccine refusal, and sharing false information online, and (ii) undergirded by a range of nonnormative personality traits and attitudes. We conclude by discussing the potential role of political leaders in propagating science-related conspiracy theories and the implications for preventing or reversing science-related conspiracy theory beliefs.
