The new survey from PBS NewsHour, NPR and Marist Poll found that 59 percent of Americans say it is hard to identify false information — intentionally misleading and inaccurate stories portrayed as truth — on social media. Another 37 percent disagreed, saying it is easy to spot.

Furthermore, with the 2020 presidential campaign about to pick up in earnest, more than half of U.S. adults said discerning these fake or deceptive stories has become increasingly difficult over the last four years. That sentiment was shared by 58 percent of Democrats, 55 percent of independents and a slightly lower proportion of Republicans at 44 percent.
