The Center for Countering Digital Hate published The Disinformation Dozen" " a report on the 12 influencers it claimed were responsible for 65 percent of anti-vaccine falsehoods disseminated on Facebook and other social media platforms. But the story of charlatans peddling fake cures and political conspiracy theories isn't the only part of the Covid misinformation saga. Distrust in public-health messaging is also sown when public-health messengers show themselves to be less than completely trustworthy. The latest set-to in this drama was a July 20 screaming match between Dr. Anthony Fauci and Senator Rand Paul. The Kentucky Republican suggested that Fauci had lied to Congress in claiming that the National Institutes of Health had never funded gain-of-function research at the Wuhan Institute of Virology. Fauci took vehement exception, saying the research that the N.I.H. had funded ... didn't qualify as gain-of-function, a research technique in which a pathogen is made more transmissible. The larger truth " obscured until recently by fervent efforts (including by Fauci) to dismiss the lab-leak theory for the origins of the pandemic " is that the U.S. government's scientific establishment did support gain-of-function research that deserved far more public debate than it got. Beneficiaries of that funding engaged in deceptive tactics and outright mendacity to shield their research from public scrutiny while denouncing their critics as conspiracymongers.
