Users preferentially consume information according to their system of beliefs and the strife within users of opposite worldviews (e.g., scientific and conspiracist) may result in heated debates. In this work we provide a genuine example of information consumption on a set of 1.2 million of Facebook Italian users. We show by means of a thorough quantitative analysis that information supporting different worldviews ? i.e. scientific and conspiracist news ? are consumed in a comparable way. Moreover, we measure the effect of 4709 evidently false information (satirical version of conspiracist stories) and 4502 debunking memes (information aiming at contrasting unsubstantiated rumors) on polarized users of conspiracy claims.
