Facebook spokeswoman Danny Liver said: “The fact that we haven’t put in the resources to fight Covid’s misinformation and support the vaccine rollout is not justified by the fact.” “With no standard definition for vaccine misinformation, and with both false and true content (often shared by mainstream media) potentially discouraging vaccine acceptance, we focus on the outcome – people using Facebook accepting Covid-19 vaccines To measure whether. “

Facebook officials, including its chief executive Mark Zuckerberg, have said the company is committed to removing the misinformation of Kovid-19 since the outbreak. The company said it had deleted more than 18 million pieces of Covid-19 misinformation, although it did not specify a timeline.

Experts who studied the disinformation said that the pieces that Facebook removed were not as informative as how many were uploaded to the site, or people were seen spreading false information in groups and pages.

“They need to open BlackBox which is their content ranking and content amplification architecture. Take that black box and open it up for audit by independent researchers and the government, “said Imran Ahmed, chief executive of the nonprofit Center for Countering Digital Hat, which aims to fight disinformation.” We don’t know how many Americans are infected with misinformation.

Mr. Ahmed’s group, using publicly available data from Facebook-owned program CrowdTangle, found that 12 people were responsible for 65 percent of the Covid-19 misinformation on Facebook. The White House, including Mr. Biden, has been repeating the figure in recent weeks. Facebook says it’s wrong but doesn’t give details.

Renee Deresta, a disinformation researcher at Stanford’s Internet Observatory, called on Facebook to release more granular data that would help experts understand how false claims about the vaccine are affecting certain communities in the country. The information, known as “comprehensive information”, essentially looks at how comprehensive the story is, such as what percentage of the community on the service sees it.

“The need for more granular comprehensive data is the reason that false claims do not spread evenly across all audiences,” Ms. Diresta said. “In order to effectively combat the specific misconceptions that communities are seeing, civil society organizations and researchers need a better understanding of what is happening in those groups.”
