"Election officials and researchers from Arizona to Taiwan are adopting a radical playbook to stop falsehoods about voting before they spread online, amid fears that traditional strategies to battle misinformation are insufficient in a perilous year for democracies around the world. Modeled after vaccines, these campaigns — dubbed “prebunking” — expose people to weakened doses of misinformation paired with explanations and are aimed at helping the public develop “mental antibodies” to recognize and fend off hoaxes in a heated election year.  Prebunking draws inspiration from “inoculation theory,” which was developed by the social psychologist William J. McGuire in the 1960s. McGuire posited that you could prepare people to reject a misguided argument by first exposing them to a weakened form of that argument, along with a strong refutation of it — sort of like a vaccine for the mind. Then when people encounter that argument in the wild, the theory goes, they recognize it and are less likely to fall for it.(Washington Post)
