Facebook Data Whistleblower: 'Fake News to the Next Level'

Wylie left Cambridge Analytica in 2014, and it's not clear how the firm targeted people with misinformation during the 2016 presidential campaign. What is clear is that two-thirds of Americans get at least some of their news on social media, according on Pew Research Center, and about 20 percent do so "often." While people don't exist in a Facebook-only vacuum, it is possible that bogus information users saw on the site could later be reinforced by the "rabbit hole" of clicks and conspiracy sites on the broader internet, as Wylie described.
