Fact-checking is increasingly important in an era of disinformation on social media, especially with the current COVID pandemic, but an article for MedPage Today calls into question the process for Facebook’s medical fact-checking.
After an op-ed in the Wall Street Journal by Marty Makary, MD, MPH, Johns Hopkins professor and editor-in-chief at MedPage Today, was labelled “misleading” by Facebook fact checkers, another op-ed in MedPage Today asks how the social media giant is choosing its medical fact-checkers.
Mystified by why this would be labelled “misleading” by Facebook, and setting aside the ‘veracity’ of the article, Vinay Prasad, MD, MPH, a haematologist-oncologist and associate professor of medicine at the University of California San Francisco, investigated the website HealthFeedback.org that Facebook uses to fact-check some of its medical articles.
The process involves two to four reviewers chosen to examine an article. Prior to the COVID pandemic, medical fact checking appears to have been done by academics, but the flood of disinformation has resulted in the change of this process, Dr Prasad noted.
In one instance, a reviewer for the article was selected because he had already written an article critical of Dr Markary’s op-ed: in other words, he was selected because he had already announced his bias.
The website’s picking and choosing of reviewers “felt like a high school clique”, Dr Prasad wrote. One that allowed them to confirm their previously held ideas about COVID and extinguish differing viewpoints. Labelling the alternative views as misleading “instantly usurps the reader of their ability to make up their own mind. It is antithetical to the spirit of the academy.”
He found that the fact-checkers typically had large Twitter followings, while the typical medical professor seems to have them in the hundreds. This makes sense, Dr Prasad wrote, as leading academics and authorities are likely too busy to be courting large numbers of followers on Twitter.
Other than a “vague explanation” of the feedback process, Dr Prasad could not find any information on how Facebook chooses its reviewers, which of the billions of posts and articles on Facebook to fact-check, whether anyone is paid and how appeals are made.
