In social media, sharing posts exposes a larger number of users to the preferred content of their peers. As users select or discard content, they collectively highlight facets of events or issues as to promote a particular interpretation.

We model cognitive dissonance modeling time-to-retweet and exemplify the proposed theory with a study of recent protest events in Argentina.
