Question: Conspiracy Theory In a recent survey, Americans were asked about 20 popular conspiracy theories. Thirty-seven percent of voters believe global warming is a hoax, 21% are certain a UFO crashed in Roswell, New Mexico, and 7% believe the moon landings were faked. (You might consider investigating the theory about lizard people who control our society.) The survey results were often very different according to political affiliation.
