A much-talked-about article called "The Real Computer Virus" was published in the American Journalism Review in 2001. It forwarded the idea of the threat posed by the rapid spread of misinformation online, essentially that the water-cooler rumor mill has now gone global. Ten years on, the point still stands.
And there is perhaps no better example than in the army of untruths that has marched on America regarding the Affordable Care Act, colloquially known as Obamacare.
As evidence of how much misinformation about the bill still stands, here is a Washington Post poll showing that four out of 10 Americans are not even aware of whether or how the Supreme Court announced its ruling on the bill, surely the biggest news event of last week.
Because of the level of misinformation out there, The Henry J. Kaiser Family Foundation has put together a 10-question quiz on the basics of the bill and the biggest myths about it to test your knowledge.
The quiz takes about two minutes and can be found here.
