What was the paper about?
The paper reports on an analysis of the spread of “fake-news” on twitter. The study analysed 126,000 Twitter stories or “cascades” (unbroken chains of retweets with a common, singular origin), tweeted by ~3 million people more than 4.5 million times, and showed that false news spread wider and faster than true ones.
When the stories were controlled for bots, the study found that bots spread stories approximately equally whether false or true, indicating that human activity was by far the largest cause of the spread of fake news.
Of the 126,000 stories, the largest category (political stories) comprised 45,000 stories.
The study also used an LDA model with 200 topics, to calculate whether stories were novel compared to a general user’s feed. The study found that false news was significantly more novel than truth, potentially leading to its increased sharing as it also resulted in responses that had more surprise.
