“The study concludes that media sources have a significant impact on the number of questions that people were able to answer correctly,” wrote Cassino and his colleagues. “The largest effect is that of Fox News: all else being equal, someone who watched only Fox News would be expected to answer just 1.04 domestic questions correctly—a figure which is significantly worse than if they had reported watching no media at all. On the other hand, if they listened only to NPR, they would be expected to answer 1.51 questions correctly.”
This should come as no surprise if you follow Fox. Consider some recent history. Fox and Friends host Steve Doocy invented a quotation from President Obama completely out of thin air. He falsely claimed that Obama had said he and Michelle were not born with silver spoons in their mouths “unlike some people,” in reference to Mitt Romney’s privileged upbringing. In fact, Obama did not say “unlike some people” and he has been using the silver spoon line for years. Several other news outlets repeated Doocy’s assertion as fact and Doocy initially avoided correcting the record after it was revealed he was wrong. Eventually he admittedthat he “seemed to misquote” Obama, instead of stating that he did, in fact, misquote him. And he did not apologize for the error.
