Why are so many Americans uninformed about the world around them? A Newsweek study asked 1,000 U.S. citizens to take the nation’s official citizenship test, and the results may shock you.

More than three million immigrants took the test from October 2009 to August 2013. Roughly 92 percent of applicants passed it.

'Watters' World' Finds Out What Americans (Don't) Know About U.S. Presidents

Among U.S. citizens in the study, 29 percent could not name the vice president, 43 percent were unable to define the Bill of Rights, and a startling 40 percent did not know America fought Japan and Germany in World War II. Also, 73 percent did not know communism was the main concern of the Cold War, and 67 percent couldn't identify capitalism as our economic system.

Another poll found that one in four Americans couldn't name more than one of the five freedoms in the First Amendment.  But more than half of those polled could name at least two members of “The Simpsons” cartoon family.

“That’s a disaster,” Bill O’Reilly said, reacting to the findings in his Talking Points Memo.

People Signing Away Rights to 'Support Obama'? Yep.

The Factor host said the public school system is a main culprit by not teaching history, geography and civics effectively.

He blamed the Internet for creating a generation of "self-absorbed, addicted, distracted and ignorant people."

The result, O’Reilly said, is that a select few “shrewd” people are wielding enormous power. “Many Americans are now voting for what they can get, not for what is best for this nation.”

O’Reilly said America is in decline because so many citizens are not paying attention and are not interested in the welfare of the country.

Is America Going to Pot?

Juan Williams agreed with O’Reilly’s analysis. “If people don’t know what’s in the Constitution, how do you then stand up for your constitutional rights?”
