American voters were quizzed on their knowledge of issues and facts raised in the 2010 midterm elections, in a survey by World Public Opinion, a project managed by the Program on International Policy Attitudes at the University of Maryland.

Respondents were also asked where they get their news from: Fox News, MSNBC, CNN, newspapers, network TV news, public broadcasting.

The survey found that "substantial levels of misinformation were present in the daily consumers of all news sources." But Fox News viewers were significantly more likely to be misinformed than those who get their news from other sources. And, greater exposure to Fox News increased the degree to which viewers were misinformed.

This is not simply a matter of partisan bias. People who vote Democratic and watched Fox News were also more likely to be misinformed than those who did not watch it – though by a lesser margin than those who vote Republican. Those who got their news from NPR, CNN, or MSNBC were better informed on most – but not all – of the issues in the survey.

We've presented the 11 questions just as the survey asked them. How well informed are you?
