On Twitter, limited number of characters spreading fake info

WASHINGTON (AP) — A tiny fraction of Twitter users spread the vast majority of fake news in 2016, with conservatives and older people sharing misinformation more, a new study finds. Scientists examined more than 16,000 U.S. Twitter accounts and found that 16 of them — less than one-tenth of 1 percent — tweeted out nearly 80 percent of the misinformation masquerading as news, according to a study Thursday in the journal Science . About 99 percent of the Twitter users spread virtually no fake information in the most heated part of the election year, said study co-author David Lazer, a Northeastern University political and computer science professor.
