Does 'Fake News' Travel Faster than 'Real News'? (Spoiler: No.)

The COVID-19 online edition of the wonderful Social Media & Society conference has just started, and my colleague Tobias Keller and I are presenting our latest research via a YouTube video that has now been released. In our study we examine the average dissemination curves for news articles from mainstream and fringe news sources; this analysis is prompted by the persistent media framing of past research as (supposedly) showing that ‘fake news’ disseminates more quickly than ‘real news’.

Leaving aside such disputed labels, we find no evidence of any systematic differences in dissemination speeds on Twitter: during 2019, for example, stories from the Australian Broadcasting Corporation’s ABC News site (Australia’s most trusted news source) disseminated almost exactly as quickly as those from the hyperpartisan outlet Breitbart: on average, both reached 25% of their eventual dissemination within just under four hours, and 50% after ten hours.

There are, though, notable differences between different site types: content from specialist sites like The Conversation (which publishes scholarly findings and commentary for a general audience) or Judicial Watch (engaging in hyperpartisan legal commentary and lawfare) usually disseminates considerably more slowly than material from more generalist news sites, from the mainstream or the fringes.

Here are the video and slides from our presentation – and a work-in-progress paper (though focussing on only one month of data, rather than all of 2019) is also online.
