From Belief in Conspiracy Theories to Trust in Others: Which Factors Influence Exposure, Believing and Sharing Fake News

Drawing on social-psychological and political research, we offer a theoretical model that explains how people become exposed to fake news, come to believe in them and then share them with their contacts. Using two waves of a nationally representative sample of Chileans with internet access, we pinpoint the relevant causal factors. Analysis of the panel data indicate that three groups of variables largely explain these phenomena: (1) Personal and psychological factors such as belief in conspiracy theories, trust in others, education and gender; (2) Frequency and specific uses of social media; and (3) Political views and online activism. Importantly, personal and political-psychological factors are more relevant in explaining this behavior than specific uses of social media.
