Scientists from the University of Cambridge, led by Dutch social psychologist Dr Sander van der Linden, are developing a method to ‘vaccinate’ news readers against misinformation.
Their research, using climate change denial as an example, shows that it works well to briefly mention that there is criticism against the consensus on the subject, but provide an easy-to-refute example of this. When someone will later come across similar criticism in a fake news story, they will be prone to reject it. However, if conspiracy theories are given too much attention, and treated with a more detailed debunk, this has an adverse effect on the readers, who will more likely believe the next hoax article that they are presented with.
The key is finding the right dosage that helps people protect themselves against nonsense.
