An MIT researcher hopes his study of fake news will encourage other scholars to take a closer look at why humans seem hard-wired to spread false news online and seek out ways to nudge people toward the truth.Data scientist Soroush Vosoughi’s work, published last week in Science, examined 126,000 “rumor cascades” of stories shared by 3 million people and found that the true stories took six times longer to reach 1,500 people than the fake ones, with false political stories going deeper, broader and ultimately reaching more people.
