Facebook made a few noteworthy changes to its misinformation policies this week, including the news that the company will now allow claims that COVID was created by humans — a theory that contradicts the previously prevailing assumption that humans picked up the virus naturally from animals.

“In light of ongoing investigations into the origin of COVID-19 and in consultation with public health experts, we will no longer remove the claim that COVID-19 is man-made from our apps,” a Facebook spokesperson told TechCrunch. “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.”

The company is adjusting its rules about pandemic misinformation in light of international investigations legitimating the theory that the virus could have escaped from a lab. While that theory clearly has enough credibility to be investigated at this point, it is often interwoven with demonstrably false misinformation about fake cures, 5G towers causing COVID and most recently the false claim that the AstraZeneca vaccine implants recipients with a Bluetooth chip.

Earlier this week, President Biden ordered a multi-agency intelligence report evaluating if the virus could have accidentally leaked out of a lab in Wuhan, China. Biden called this possibility one of two “likely scenarios.”

“… Shortly after I became President, in March, I had my National Security Advisor task the Intelligence Community to prepare a report on their most up-to-date analysis of the origins of COVID-19, including whether it emerged from human contact with an infected animal or from a laboratory accident,” Biden said in an official White House statement, adding that there isn’t sufficient evidence to make a final determination.

Claims that the virus was man-made or lab-made have circulated widely since the pandemic’s earliest days, even as the scientific community largely maintained that the virus probably made the jump from an infected animal to a human via natural means. But many questions remain about the origins of the virus and the U.S. has yet to rule out the possibility that the virus emerged from a Chinese lab — a scenario that would be a bombshell for international relations.

Prior to the COVID policy change, Facebook announced that it would finally implement harsher punishments against individuals who repeatedly peddle misinformation. The company will now throttle the News Feed reach of all posts from accounts that are found to habitually share known misinformation, restrictions it previously put in place for Pages, Groups, Instagram accounts and websites that repeatedly break the same rules.
