Facebook fed posts with violence and nudity to people with low digital literacy skills – USA TODAY

Two years ago, Facebook researchers conducted a five-question survey designed to assess its users’ digital literacy skills.
It tested users on how well they understood Facebook’s app interface and terms like “tagging” someone on social media. Their score was the number of questions they answered correctly. The researchers then compared the users’ scores to the types of content Facebook’s algorithms fed them over a 30-day period.
