Misinformation can undermine critical public health efforts around the world to counter the coronavirus pandemic. Worse, amplified by social media, misinformation has the potential to fuel false conspiracy theories.
Twitter recently announced plans to add labels and warning messages on some tweets with disputed or misleading information about COVID-19 as part of a new approach to misinformation that will eventually extend to other topics.
The company said that depending on the propensity for harm and type of misleading information in the tweet, warnings may also be added to say the tweet conflicts with guidance from public health experts before a user views it.
Facebook, which recently reported a sharp increase in the number of posts it removed for promoting violence and hate speech across its apps, has also put warning labels on about millions of pieces of content related to COVID-19, after taking the unusually aggressive step of banning harmful misinformation about the new coronavirus at the start of the pandemic.
"We have a good sense that these warning labels work. Ninety-five percent of the time that someone sees content with a label, they don't click through to view that content," Facebook Chief Executive Mark Zuckerberg told reporters on a press call.
