WHO is fighting false COVID info on social media. How's that going?
Researchers say there are limits to some of the anti-misinformation tactics used by social media companies.
Flagging or pulling down a problematic social media post often comes too late to undo the harm, says Nasir Memon, professor of computer science and engineering at New York University. His research includes cybersecurity and human behavior.
"It only comes after the post has gone viral. A company might do a fact check and put a warning label," he says. "But by then the ones who consumed that information already have been influenced in some way."
