For anyone following the war on science over the last 30 years or so, it was clear that the general movement to delegitimize real expertise and disinform the public, eventually would become a threat to democracy. Welcome to 2017.
Researchers used the hoary “30,000 scientists’ petition as a test case of climate denial nonsense. It is, according to John Cook, actually one of the most shared denial memes on Facebook – which probably accounts for the continued popularity of my vid, above.
Expect the anti-vaxxers out on this one.
In medicine, vaccinating against a virus involves exposing a body to a weakened version of the threat, enough to build a tolerance
Social psychologists believe that a similar logic can be applied to help “inoculate” the public against misinformation, including the damaging influence of ‘fake news’ websites propagating myths about climate change.
A new study compared reactions to a well-known climate change fact with those to a popular misinformation campaign. When presented consecutively, the false material completely cancelled out the accurate statement in people’s minds – opinions ended up back where they started.
Researchers then added a small dose of misinformation to delivery of the climate change fact, by briefly introducing people to distortion tactics used by certain groups. This “inoculation” helped shift and hold opinions closer to the truth – despite the follow-up exposure to ‘fake news’.The study on US attitudes found the inoculation technique shifted the climate change opinions of Republicans, Independents and Democrats alike.“Misinformation can be sticky, spreading and replicating like a virus,” says lead author Dr Sander van der Linden, a social psychologist from the University of Cambridge and Director of the Cambridge Social Decision-Making Lab.
“We wanted to see if we could find a ‘vaccine’ by pre-emptively exposing people to a small amount of the type of misinformation they might experience. A warning that helps preserve the facts.
“The idea is to provide a cognitive repertoire that helps build up resistance to misinformation, so the next time people come across it they are less susceptible.”
To find the most compelling climate change falsehood currently influencing public opinion, van der Linden and colleagues tested popular statements from corners of the internet on a nationally representative sample of US citizens, with each one rated for familiarity and persuasiveness.
The winner: the assertion that there is no consensus among scientists, apparently supported by the Oregon Global Warming Petition Project. This website claims to hold a petition signed by “over 31,000 American scientists” stating there is no evidence that human CO2 release will cause climate change.
