This obsession with "fake" news is all about one thing: government censorship.
All this study proves is that young kids are gullible (duh) and our public education system is one of the worst in the world (not news).
First liberals complained about Citizens United endlessly. And now that Trump won with far less spending than Hillary, suddenly they're concerned about "fake" news while ignoring the false editorializing of the liberal media and rampant lead burying.
Liberal Fascists just can't stand that they no longer control the narrative. And it's really a thumb in their eye whenever Trump tweets out something they don't like. Historically, if the President wanted to say something, they had to go through the filter of the press.
And good riddance.
