A survey of 1,010 randomly selected adults asked about media use and belief in three conspiracy theories about the attacks of September 11, 2001. "Paranoid style" and "cultural sociology" theories are outlined, and empirical support is found for both. Patterns vary somewhat by conspiracy theory, but members of less powerful groups (racial minorities, lower social class, women, younger ages) are more likely to believe at least one of the conspiracies, as are those with low levels of media involvement and consumers of less legitimate media (blogs and grocery store tabloids). Consumers of legitimate media (daily newspapers and network TV news) are less likely to believe at least one of the conspiracies, although these relationships are not signifcant after controlling for social structural variables. Beliefs in all three conspiracies are aligned with mainstream political party divisions, evidence that conspiracy thinking is now a normal part of mainstream political conflict in the United States.In the last twenty years there has been a surge of scholarly interest in rumors and conspiracy theories. Only a few have conducted systematic studies of conspiracy believers or the social factors contributing to belief, but there is no shortage of thoughtful and provocative theorizing. Much of this expanding literature suggests that conspiracy theories provide clarity of vision and clear targets for addressing the confusions, frustrations, and insecurities of living in contemporary societies which are characterized by rapid social change; a multiplicity of voices and interests; multi-level, multi-polar balances of power where those at higher levels maintain control through secrecy and controlling information; declining individual autonomy; increasing risk awareness associated with technological advances and "post-scarcity" conditions; high levels of social and geographic mobility; declining trust in national governments; and post-9 / 11 fears of terrorist/outsider threats.' While these theories are stimulating and insightful, we believe there is a need to bring more systematic evidence to bear on two basic questions: Who believes conspiracy theories, and what sources of information are associated with believing conspiracy theories?
