Myths in education can be expensive, sometimes funny and can make me sometimes start to throwing things. But most of the time they are not too harmful, except maybe for your wallet. This research by Daniel Jolley and Karen Douglas talks about a whole other level. A belief in conspiracy theories may influence parents’ intentions to have their children vaccinated against diseases such as measles.

From the press release:

Jolley and Douglas asked a sample of 89 parents about their views on anti-vaccine conspiracy theories and then asked participants to indicate their intention to have a fictional child vaccinated. They found that stronger belief in anti-vaccine conspiracy theories was associated with less intention to have the child vaccinated.

In a second study of 188 participants, Jolley and Douglas exposed participants to information concerning anti-vaccine conspiracy theories. It was found that reading this material reduced participants’ intention to have a fictional child vaccinated, relative to participants who were given refuting information, or those in a control condition.

Daniel Jolley said: “The recent outbreak of measles in the UK illustrates the importance of vaccination. Our studies demonstrate that anti-vaccine conspiracy theories may present a barrier to vaccine uptake.”

Dr Douglas added: “Our findings point to the potentially detrimental consequences of anti-vaccine conspiracy theories. It is easy to treat belief in conspiracy theories lightly, but our studies show that wariness about conspiracy theories may be warranted.”
