In 2013, Public Policy Polling (PPP) surveyed 1,247 registered American voters on a range of conspiracy theories. This blog post looks at six of them:
|Conspiracy theory||Believe||Disbelieve||Not sure|
|TV mind control||15%||70%||15%|
|Moon landing fake||7%||84%||9%|
The Roswell theory is that a UFO crashed at Roswell, New Mexico in 1947, and the US government covered it up. In fact, we now know that what they covered up was a classified military balloon project.
Many people, sadly, believe in a Vaccines/autism link, thanks to some fraudulent research. Several large-scale studies prove conclusively that there is no such link (for example, a Danish study of 537,303 children).
Many people believe in TV mind control, i.e. that the government and/or media secretly adds mind-controlling signals to TV broadcasts. Some wear tin foil hats (above) to protect themselves from this imaginary danger.
Many also believe, implausibly, that the 1969 NASA Moon landing was fake. This idea has been thoroughly debunked, and it was never very believable. For one thing, it assumes that hundreds of thousands of people around the world (including many Australians) would have kept the conspiracy a secret.
Also popular is the Chemtrails theory, that contrails seen in the sky are actually chemicals being sprayed by the government for sinister reasons. In fact, there is no evidence to support the idea, it’s ridiculous to believe that conspirators would spray themselves, the physics of contrails is well understood, and contrails have been around since World War II (as the 1943 photo above by Sgt. Stanley M. Smith, USAF proves).
Finally, the Lizard people theory is that the world is secretly run by shape-shifting lizards in human form. I cannot even imagine why someone would believe that.
The chart below shows the breakdown of the PPP results by sex, political party, race, and age (click to zoom):
This chart only shows the percentages who are sure of their belief in these conspiracy theories. The substantial “Not sure” numbers (in the table at the top of this post) are not included. The chart below shows how much more likely different groups are to believe a theory than average. The most gullible groups seem to be people under 30 and “other races” (i.e. not Hispanic, White, or African-American). African-Americans seem quite sceptical of many of the six conspiracy theories listed here (although other conspiracy theories are accepted – see the complete survey results). Republicans are slightly more likely than Democrats (14% vs 11%) to believe the six conspiracy theories listed here.
Overall, the results suggest that many people in the USA lack the ability to accurately evaluate the truth or falsity of a statement. This does not reflect well on the educational system there. That said, I’m not sure that things are actually better here in Australia.
