« We believe providing more context can help people decide for themselves what to trust and what to share. We’ve started a program to work with third-party fact checking organizations that are signatories of Poynter’s International Fact Checking Code of Principles. We’ll use the reports from our community, along with other signals, to send stories to these organizations. If the fact checking organizations identify a story as fake, it will get flagged as disputed and there will be a link to the corresponding article explaining why. Stories that have been disputed may also appear lower in News Feed.
