Facebook has been concerned about fake news stories that circulate on its social platform and how often such incidents occur. The company has had high-level internal debates over the matter since May, discussing different options to curb movements of hoax and false stories. Gizmodo reports Monday that Facebook executives conducted a wide-ranging review of products and policies earlier this year with "the goal of eliminating any appearance of political bias." The company even had a major update for the News Feed planned which could have supposedly filtered fake stories, but the update never saw the light of the day because it was afraid to use it. From the report:One source said high-ranking officials were briefed on a planned News Feed update that would have identified fake or hoax news stories, but disproportionately impacted right-wing news sites by downgrading or removing that content from people's feeds. According to the source, the update was shelved and never released to the public. It's unclear if the update had other deficiencies that caused it to be scrubbed. "They absolutely have the tools to shut down fake news," said the source, who asked to remain anonymous citing fear of retribution from the company. The source added, "there was a lot of fear about upsetting conservatives after Trending Topics," and that "a lot of product decisions got caught up in that." In an emailed statement, Facebook did not answer Gizmodo's direct questions about whether the company built a News Feed update that was capable of identifying fake or hoax news stories, nor whether such an update would disproportionately impact right-wing or conservative-leaning sites. Instead, Facebook said it "did not build and withhold any News Feed changes based on their potential impact on any one political party."
