Here are my picks for the 10 worst predicitons of 2012:
1. The World Will End in 2012: By the Mayans (but not really)
Let's get one thing clear: The ancient Mayans did not believe the world was going to end on Dec. 21, 2012, and it's not even certain the date had any significance for them.
Some archaeologists believe that Dec. 21 will mark the end of the "Great Cycle" of 13 baktuns, the 1,872,000-day periods that are the largest unit of time on the ancient Mayan calendar, which is no longer in use among the Mayans' descendants. Others believe it will be Dec. 23 or a different day entirely.
So where did the idea that Dec. 21 equals the apocalypse come from? Author Michael Coe first popularized the theory that the Mayans believed this date is when the world would end - for what it's worth, he didn't actually believe they were right - but later archaeologists disputed his interpretation and recently discovered calendars that show dates thousands of years past 2012.
None of that has stopped a cottage industry of doomsday prophets from cashing in on the phenomenon, often connecting it to similarly crackpot ideas about solar flares, shifting global polarities, extraterrestrials, and the phantom planet Nibiru (and of course, that movie).
It's easy to laugh at the 2012ers, though the hysteria has had occasionally tragic consequences. An Ipsos poll conducted in 21 countries this year found that 8 percent of respondents were experiencing anxiety over the "prophesy."
In Russia, there have been several documented cases of "collective mass hysteria" over the date, with worried citizens raiding stores to stock up for the apocalypse. In China, more than 1,000 members of a doomsday cult preparing for the apocalypse on Dec. 21 were arrested.
