There is rising pressure worldwide to investigate the origins of the pandemic, including the possibility that the Covid-19 virus—the SARS-CoV-2—came from a lab in Wuhan, China.
Facebook will no longer remove posts claiming that Covid-19 is human-made or manufactured, “in light of ongoing investigations into the origin of Covid-19 and in consultation with public health experts”, the world’s largest social media network said.
There is rising pressure worldwide to investigate the origins of the pandemic, including the possibility that it came from a lab. Since the pandemic began, Facebook has been changing what it allows on the topic and what it bans. In February, it announced a host of new claims it would be prohibiting—including that Covid-19 was created in a Chinese lab. Other claims it added at the time included the false notion that vaccines are not effective or that they are toxic.
Lisa Fazio, a professor of psychology at Vanderbilt University, said the reversal shows the difficulty of fact-checking in general, particularly with something unprecedented like the coronavirus, when experts can disagree and change their minds with new evidence.
“It’s one reason that content moderation shouldn’t be static, scientific consensus changes over time,” Fazio said. “It’s also a reminder to be humble and that for some questions the best current answer is “we don’t know yet” or “it’s possible, but experts think it’s unlikely.”
Facebook’s reversal comes as President Joe Biden ordered US intelligence officials to “redouble” their efforts to investigate the origins of the Covid-19 pandemic, including any possibility the trail might lead to a Chinese laboratory. After months of minimising these claims as a fringe theory, the Biden administration is joining worldwide pressure for China to be more open about the outbreak. It aims to head off GOP complaints that Biden has not been tough enough and to use the opportunity to press China on alleged obstruction.
“We’re continuing to work with health experts to keep pace with the evolving nature of the pandemic and regularly update our policies as new facts and trends emerge,” Guy Rosen, Facebook’s vice president of integrity, said in a statement on Wednesday.
Facebook does not usually ban misinformation outright on its platform, instead adding fact-checks by outside parties, which includes The Associated Press, to debunked claims. The two exceptions have been around elections and Covid-19.
