I thought you'd like this, then, a quick compilation of the percentage of Americans who believe in the kookier theories. These are the percentages of U.S. adults, based on a national survey, who are certain, are definite, in their belief. If we add in the "probably" then the number increases. Those are in parentheses. Yup, I've got the raw data.
- Feds directed Katrina flooding into poor areas -- 2.5 percent (12.8)
- Obama born outside the U.S. -- 5.6 percent (16.7).
- Death panels are in Obamacare -- 8.1 percent (25.9).
- Feds knew of 9/11 in advance -- 9.5 percent (26.4).
I expect to do a paper on this in the next few months, one that gets into who believes in this (demographics, political factors, media use, etc.). It's an area so ripe for research, I half wish I didn't have two other things in the queue to finish first.
Note: Corrected the second-to-last graph to reflect it's 9/11 that 1-in-4 believe in, not Katrina.
