For all categories of information — politics, entertainment, business and so on — we found that false stories spread significantly farther, faster and more broadly than did true ones. Falsehoods were 70 percent more likely to be retweeted, even when controlling for the age of the original tweeter’s account, its activity level, the number of its followers and followees, and whether Twitter had verified the account as genuine. These effects were more pronounced for false political stories than for any other type of false news.
