Fairleigh Dickinson University conducted a study about Fox News viewers in New Jersey.
Jerseyans were surveyed about the uprisings in Egypt and Syria.
With education and partisanship accounted for, the study showed "people who watch Fox News are 18-points less likely to know that Egyptians overthrew their government" and 6-points less likely to know that Syrians have not yet overthrown their government" compared to Jerseyans who don't watch news at all.
Overall numbers include 53% knew of Egypt and 48% knew of Syria.
Because of the controls for partisanship, we know these results are not just driven by Republicans or other groups being more likely to watch Fox News. Rather, the results show us that there is something about watching Fox News that leads people to do worse on these questions than those who don’t watch any news at all.
Reports also said that this is not the first study to conclude this way.
Last year, a University of Maryland study show Fox News viewers were more likely to believe false information about politics.
