Internal Bug Promoted Problematic Content on Facebook

Content identified as misleading or problematic were mistakenly prioritized in users' Facebook feeds recently, thanks to a software bug that took six months to fix, according to tech site The Verge.

Facebook disputed the report, which was published Thursday, saying that it "vastly overstated what this bug was because ultimately it had no meaningful, long-term impact on problematic content," according to Joe Osborne, a spokesman for parent company Meta.

But the bug was serious enough for a group of Facebook employees to draft an internal report referring to a "massive ranking failure" of content, The Verge reported.

In October, the employees noticed that some content which had been marked as questionable by external media -- members of Facebook's third-party fact-checking program -- was nevertheless being favored by the algorithm to be widely distributed in users' News Feeds.

"Unable to find the root cause, the engineers watched the surge subside a few weeks later and then flare up repeatedly until the ranking issue was fixed on March 11," The Verge reported.

But according to Osborne, the bug affected "only a very small number of views" of content.

That's because "the overwhelming majority of posts in Feed are not eligible to be down-ranked in the first place," Osborne explained, adding that other mechanisms designed to limit views of "harmful" content remained in place, "including other demotions, fact-checking labels and violating content removals."

AFP currently works with Facebook's fact checking program in more than 80 countries and 24 languages. Under the program, which started in December 2016, Facebook pays to use fact checks from around 80 organizations, including media outlets and specialized fact checkers, on its platform, WhatsApp and on Instagram.

Content rated "false" is downgraded in news feeds so fewer people will see it. If someone tries to share that post, they are presented with an article explaining why it is misleading.

Those who still choose to share the post receive a notification with a link to the article. No posts are taken down. Fact checkers are free to choose how and what they wish to investigate.

President Donald Trump took to social media Thursday morning to support Elon Musk's car company, a startling development given their bitter public feud.

”I want Elon, and all businesses within our Country, to THRIVE,” Trump wrote on Truth Social, Reuters reported.

The post wasn't enough to help Tesla's stock, which fell sharply after the company reported another quarter of lackluster financial results and Musk warned of some potentially “rough quarters” into next year. At midday, the stock was down around 9%.

Late Wednesday, Tesla said revenue fell 12% and profit dropped 16% in the April-June quarter. Many prospective buyers have been turned off by Musk’s foray into right-wing politics, and the competition has ramped up in key markets such as Europe and China.

Investors have been unnerved by Musk's social media spat with the president because Trump has threatened to retaliate by ending government contracts and breaks for Musk's various businesses, including Tesla.

But Trump struck a starkly different tone Thursday morning.

“Everyone is stating that I will destroy Elon’s companies by taking away some, if not all, of the large scale subsidies he receives from the US Government. This is not so!" Trump wrote. “The better they do, the better the USA does, and that’s good for all of us.”

After Trump's massive budget bill passed earlier this month, Tesla faces the loss of the $7,500 EV tax credit and stands to make much less money from selling regulatory credits to other automakers. Trump’s tariffs on countries including China and Mexico will also cost Tesla hundreds of millions of dollars, the company said on its earnings call.

Musk has blasted the budget bill on his own social media platform X for adding to US debt at a time when it is already too large. The Tesla CEO has called the budget pushed by the president a “disgusting abomination” and has threatened to form a new political party.

On Wednesday's call, Musk said the electric vehicle maker will face “a few rough quarters” as it moves into a future focused less on selling cars and more on offering people rides in self-driving cars. He also talked up the company's business making humanoid robotics. But he acknowledged those businesses are a ways off from contributing to Tesla’s bottom line.

Tesla began a rollout in June of its paid robotaxi service in Austin, Texas, and hopes to introduce the driverless cabs in several other cities soon. Musk told analysts that the service will be available to probably “half of the population of the US by the end of the year — that’s at least our goal, subject to regulatory approvals.”

“We’re in this weird transition period where we’ll lose a lot of incentives in the US,” Musk said, adding that Tesla “probably could have a few rough quarters” ahead. He added, though, “Once you get to autonomy at scale in the second half of next year, certainly by the end of next year, I would be surprised if Tesla’s economics are not very compelling.”
