From the Pew Research Center:
Many Americans say the creation and spread of made-up news and information is causing significant harm to the nation and needs to be stopped, according to a new Pew Research Center survey of 6,127 U.S. adults conducted between Feb. 19 and March 4, 2019, on the Center's American Trends Panel.
Indeed, more Americans view made-up news as a very big problem for the country than identify terrorism, illegal immigration, racism and sexism that way. Additionally, nearly seven-in-ten U.S. adults (68%) say made-up news and information greatly impacts Americans' confidence in government institutions, and roughly half (54%) say it is having a major impact on our confidence in each other.
U.S. adults blame political leaders and activists far more than journalists for the creation of made-up news intended to mislead the public. But they believe it is primarily the responsibility of journalists to fix the problem. And they think the issue will get worse in the foreseeable future.
