USA - Only a quarter of US adults in a recent survey could fully identify factual statements - as opposed to opinion - in news stories, the Pew Research Center found in a study released on Monday. The survey comes amid growing concerns about so-called fake news spread on the internet and social media. The term generally refers to fabricated news that has no basis in fact but is presented as being factually accurate. The study was intended to determine if respondents could differentiate between factual information and opinion statements in news stories.
