Vulnerability, self-uncertainty, and collective narcissism mediate the relationship between ostracism and conspiracy beliefs: Α representative sample study during the first wave of the pandemic
A correlational study (N=895) examined the association between ostracism and endorsement of COVID-19 conspiracy theories, the mediating role of sense of vulnerability, self-uncertainty and collective narcissism and the moderating role of conspiracy mentality. We found that ostracism positively predicted endorsement of COVID-19 conspiracy theories and this association was mediated by sense of vulnerability, self-uncertainty and collective narcissism. Conspiracy mentality moderated the relationship between ostracism with the sense of vulnerability, but not the self-uncertainty nor of the collective narcissism. Our study expands on the still very few and scarce research on ostracism and conspiracy theories, by confirming their relationship in the context of the pandemic, as well as exploring further interrelationships, responding to the recent calls for investigating the mediating role of both individual and group-level variables. Theoretical and societal implications are discussed. Results offer a novel insight in the relationship between ostracism and conspiracy theories focused on COVID-19, advancing our current knowledge and developing their relationship even further.
