Twenty
percent of people said that cellphones cause cancer — and that large
corporations are keeping health officials from doing anything about it. And
another 20 percent think doctors and the government want to vaccinate children
despite knowing that vaccines cause autism.
From
time to time, everyone has a preconceived idea about things. However,
conspiratorial thinking goes beyond that ignoring any evidence that is contrary
to the theory.
The
single most important factor leading to conspiracy belief is that it gives
people a sense of control. Someone, rather than random events, is to blame. If
a person feels discriminated against or even is unsure about their job, this
can increase the likelihood they’ll believe in a conspiracy.
Working
in AIDS, I heard a lot of discussion about the government creating HIV and the
polio vaccine was the reason so many people were infected. It was interesting
to note that as more effective treatments became available, and people had more
control over their disease, a lot of the conspiracy theory dropped out of the
conversation.
While
the Tuskegee Institute’s study of the natural course of syphilis in the 1930s on black men is very well
known, a lot of people are not aware of the eugenics movement that
swept the United States in the first half of the 20th Century. This resulted
in the sterilization of over 60,000 people who were considered “disabled” due
to mental illness or belonging to a socially disadvantaged group. Thirty states
had sterilization laws, with some of them continuing this practice into the
1970s. Eugenics: Compulsory Sterilization in 50 American States.
Chemical
and drug maker Bayer AG, knowingly sold Factor VIII, a blood clotting agent for
people with hemophilia, in the 1980s to Latin America and Asia, while marketing
a newer safer product in the United States and Europe. Since Factor VIII used
10,000 or more donors to create this product, until there was screening for HIV
thousands of people with hemophilia became infected with the AIDS virus.
Ultimately, Bayer and three other companies paid about $600 million to settle
more than 15 years of lawsuits. Associated Press
With
just these 3 examples, it’s not surprising that people believe in medically
related conspiracy theories. In the JAMA study, people were asked about six
theories. In addition to the three listed above, the other three are: the CIA
deliberately infected African Americans with HIV; genetically modified foods
are a conspiracy to reduce population worldwide; and water fluoridation is used
to cover up pollution.
While
there is good research that refutes most of these conspiracy theories, half of
the American population believes in one or more of them. This is a problem
since it results in people not receiving needed care and children not receiving
vaccinations and so conditions like pertussis (whooping cough) are on the rise.
How
do we change this? Can we change it? My sense is that the humans have always
done some version of this because it makes them feel more certain and secure.
The availability of the Internet may be adding more to it, since all kinds of
“faux” research is now easily available. Ultimately though, we each need to
make decisions about our medical care. As much as possible, choices should be
made based on our own situations and hopefully with the support of a medical
provider we trust. Finally, we all need to keep an open mind as much as possible.
