Facebook’s fight against fake news isn’t going so well

  Facebook’s fight against fake news isn’t going so well This week, Facebook’s top two executives have touted the company’s effort to fight fake news. Analytics from tracking firm NewsWhip, tweeted out by John Herrman at The New York Times, and confirmed to Quartz by NewsWhip, show that the fourth most-engaged-with story on Facebook from the first week of September 2018 is a story from America’s Last Line of Defense, which fact-checking website Snopes (which Facebook works with) has called a “junk news network.” The piece claims that Michael Jordan has resigned from Nike’s board, “taking Air Jordans with him.” It is, of course, false. (For one thing, Jordan isn’t even on Nike’s board.

Its external partners have said the system is inefficient. Some of them are getting brutally attacked online. Partisan bickering has also been an issue. And most importantly, sketchy news sources and fake stories continue to thrive on the platform.

Facebook’s executives, on the other hand, keep praising the program. And on Thursday (Sept. 13), the company announced that it would be expanding its fact-checking work to photographs and videos. In a post, Antonia Woodford, a product manager at Facebook, says it built a machine-learning model to identify potentially false images or clips. These get sent to one of Facebook’s 27 fact-checking partners who are based in 17 countries. These fact-checkers are expected to use techniques “such as reverse image searching and analyzing image metadata” to determine whether the content has been falsified.

Fact checking: The new workplace skill

  Fact checking: The new workplace skill In 2018, policy debate is often infected by the rapid dissemination of misinformation. That's why an emphasis on education in verification is increasingly important for workers, writes RMIT ABC Fact Check's Sushi Das.Young people are tech-savvy and adept users of digital media, relying on their devices for news about current affairs, their social scene or their studies.

“As we get more ratings from fact-checkers on photos and videos, we will be able to improve the accuracy of our machine learning model,” Woodford writes. The company is also working on technological solutions to determine whether visual content had been manipulated (as is the case with “deepfake” videos like this, for example).

Manipulated images are a common way to the spread of misinformation, and hoaxers are getting more and more sophisticated with their methods, but text-based articles are hard enough to check. The current system is far from perfect, and now Facebook is piling on yet another, difficult ask.

Instagram will promote mid-term voting with stickers, registration info .
Facebook is getting ready to purposefully influence the U.S. mid-term elections after spending two years trying to safeguard against foreign interference. Combined, these efforts could boost voter turnout, especially amongst Instagram's core audience of millenials. If one political party's base skews younger, they could receive an advantage.
