Despite the prevalence of antisemitism around the world, its coverage in public discourse is primarily limited to that of hate crimes or occasionally condemning politicians who say something out of line. It is not known if any specific types of thinking are related to which individuals adopt antisemitic attitudes. I obtained data from a questionnaire distributed on Amazon’s MTurk software. Participants responded to questions about magical ideation, antisemitic conspiracy theories, and the 2020 election. Those who were more antisemitic were more likely to engage in magical ideation. Participants who voted for Donald Trump were more antisemitic than those who voted for Joseph Biden. Ambiguity tolerance did not differ between participants based on their candidate. Overall, the research indicates that magical ideation is related to belief in antisemitic conspiracy theories, suggesting an important step for further research on combatting hatred and dispelling conspiracy theories.
