While conspiracy thinking has become a more pressing social problem, thus far, most research has focused on beliefs in specific conspiracy theories. Less attention has been paid to generic conspiracist beliefs, despite findings that such beliefs are among the most important predictors of beliefs in specific conspiracy theories. There is also very limited research on how media use may impact generic conspiracist beliefs. The purpose of this paper is hence to investigate the antecedents of generic conspiracist beliefs, with a particular focus on the role of media use. Utilizing a large-scale representative panel survey in Sweden, we find that media use matters, and that use of right-wing political alternative media is one of the strongest predictors of generic conspiracist beliefs.
