New research finds that misinformation on climate change can psychologically cancel out the influence of accurate statements. However, if legitimate facts are delivered with an "inoculation" -- a warning dose of misinformation -- some of the positive influence is preserved.
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.
