If you believe that the CIA deliberately infected African Americans with the HIV virus or another medical conspiracy theory, you have plenty of company: about half of all Americans, reports Reuters:
About half of American adults believe in at least one medical conspiracy theory, according to new survey results.
Some conspiracy theories have much more traction than others, however.
For example, three times as many people believe U.S. regulators prevent people from getting natural cures as believe that a U.S. spy agency infected a large number of African Americans with the human immunodeficiency virus (HIV).
J. Eric Oliver, the study’s lead author from University of Chicago, said people may believe in conspiracy theories because they’re easier to understand than complex medical information.
“Science in general – medicine in particular – is complicated and cognitively challenging because you have to carry around a lot of uncertainty,” Oliver said.
“To talk about epidemiology and probability theories is difficult to understand as opposed to ‘if you put this substance in your body, it’s going to be bad,’” he said.
