Abstract / Description of output

Warning messages are being discussed as a possible mechanism to contain the circulation of false information on social media. Their effectiveness for this purpose, however, is unclear. This article describes a survey experiment carried out to test two designs of warning messages: a simple one identical to the one used by Facebook, and a more complex one informed by recent research. We find no evidence that either design is clearly superior to not showing a warning message. This result has serious implications for brands and politicians, who might find false information about them spreading uncontrollably, as well as for managers of social media platforms, who are struggling to find effective means of controlling the diffusion of misinformation.
