A study conducted by the Stanford Graduate School of Education from January 2015 revealed difficulties that middle, high school, and college students experienced in differentiating between advertisements and news articles, or identifying where information originated.[88] One concern noted by researchers of the study is that democracy is at risk of devolving due to the ways in which falsehoods about civic issues can quickly spread with a growing ease of access. In one assessment, high school students were asked to evaluate two Facebook posts mentioning Donald Trump's candidacy for president; one was from an actual Fox News account and the other was from a fake account.[88] Over 30 percent of students stated that the fake account was more reliable because of its graphic elements and only a quarter recognized the significance of the blue checkmark on Twitter and Facebook, which indicates that an account was marked as legitimate.[88]
