The most prevalent conspiracy theory in the United States is that the government is concealing information about the 9/11 attacks with slightly over half of Americans holding that belief. Approximately half of Americans also believe in a cover up regarding the assassination of John F. Kennedy.
Significant minorities of Americans (40%+) believe the government is hiding information about extraterrestrials and global warming. Several other conspiracy theories are convincing to about a third of Americans including plans for a one world government (33%), Obama’s birth certificate (30%) and the origin of the AIDS virus.
About a fourth of Americans believe there is something suspicious about the death of supreme court justice Antonin Scalia (28%) and slightly less than a fourth think the government is covering up information on the moon landing (24%).
