In a sample of 95 U.S. undergraduates (49.5% women, Mage = 20.99 years, SD = 3.48), we analyzed the effects of symbolic threat on right-wing authoritarianism (RWA). We used data from an experimental study in which negative political attacks on one’s own favorite candidate were considered as symbolic threats. A hierarchic moderated regression showed that, as with societal threat, symbolic threat fostered an increase in RWA only among participants with low initial scores on RWA. This increase did not depend on the persuasive effect of being exposed to negative campaigning. The implications, limitations, and possible developments of the research are discussed.
