Once people have accepted false information as true, they usually don’t change their views. Research using exposure to a list of 31,000 scientists including the Spice Girls and Charles Darwin who repudiated the idea of global warming. People who knew the list was bogus before they saw it were more likely to accept the scientific consensus than those who found out the list was bogus afterward.
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, new research suggests.
