Conspiracy beliefs (i.e., beliefs in specific conspiracy theories or the more general conspiracy mentality) are associated with a need for uniqueness and lower adherence to social norms. These findings suggest that conspiracy beliefs might be generally associated with less influence by majority opinions – absolutely and compared to minority opinions. In five experiments involving scenarios unrelated to conspiracy theories (overall N = 1669), participants were informed about the majority/minority opinion on a given issue (e.g., the building of a tunnel), afterwards indicating their evaluation or voting intentions regarding the issue. We then tested whether the influence of a majority/minority opinion on evaluation or voting intentions is moderated by conspiracy beliefs. Across studies, we find no significant moderation. A meta-analysis confirms no correlation between conspiracy beliefs and susceptibility to majority influence. Taken together, our studies provide no evidence for the assumption that those holding conspiracy beliefs reject majority opinions per se.
