evidence: Facebook should immediately extend its fact-checking programme to also cover Instagram, according to Full Fact, a journalism charity that was the first UK member of the scheme. [...] Full Fact joined the fact-checking programme in January. The programme gives fact-checking organisations tools to scan Facebook for factual claims and mark them as true or false, and provide a link to a detailed assessment of their veracity. [...] The charity, which is paid by Facebook to provide the fact-checking service, listed nine other recommendations for how Facebook could improve its programme. These include automatically applying previous ratings to new attempts to repost the same claim; adding more options that lie between "true" and "false" for posts that are unsubstantiated, humorous or lacking in context; and being more open about any plans to use the results of human fact-checking to train automated systems to do the same thing.
