"The role of Fox News. In a pioneering study that laid the groundwork for much future work, the Program on International Policy Attitudes at the University of Maryland used a series of post-Iraq War polls (conducted from June through September in 2003) to analyze the the preponderance of false beliefs about the war. The study first defined three clear falsehoods: (1) real evidence linking Iraq and Al Qaeda had been uncovered; (2) WMD had been discovered in Iraq following the US invasion; and (3) global public opinion was in favor of the US invasion. Then, it examined the likelihood of holding such incorrect beliefs based upon a person's political party affiliation and habits of news consumption.
Fox viewers led the way in embracing these false assertions, with 80 percent of them believing at least one of the three. For consumers of both NPR and PBS, in contrast, only 23 percent believed one or more of these pro-war myths."
