Roughly one in 10 news websites analyzed by NewsGuard, a project launched by two respected longtime journalists, feature misinformation about health.
NewsGuard analyzed nearly 3,000 websites that account for 96 percent of online engagement among Americans, and found that 11 percent provided news with health misinformation. For instance, references to the debunked link between vaccines and autism.
NewsGuard has a system of rating sites based on reliability. Of the sites considered somewhat unreliable, nearly 40 percent publish false or unfounded health claims.
