Facebook fact-checks presidential candidate: Now-GOP presidential candidate Larry Elder posted an article February 21 from The Daily Signal, titled, “39 States Mandated Masks. Now a New Study Shows Masks Don't Work.” Facebook imposed a “Missing context” label on the post, claiming, “Independent fact-checkers say this information is missing context and could mislead people.” The fact check linked to Health Feedback and the assertion: “Inadequate support: Claims that face masks are ineffective at reducing the spread of COVID-19 based on a Cochrane review didn’t take into account the limitations of the review…the individual studies it evaluated varied greatly in terms of quality, study design, populations studied, and outcomes observed.” Multiple studies and reviews have presented evidence that masks are in fact not only ineffective at stopping COVID-19 but actively harmful.
