YouTube's Notre Dame-9/11 flub highlights AI's blind spots
YouTube might need a few more humans. The machines whose job is to tamp down conspiracy theories are not cutting it just yet.
As people around the world Monday turned to YouTube to watch Notre Dame Cathedral burn in Paris, an automated system attached background information about the Sept. 11 terror attacks in New York to livestream videos of the fire.
The cause of the blaze has not been determined, but authorities said it appeared to be accidental, not arson or terrorism.
The background note was posted by a system YouTube recently put in place to combat well-known conspiracies about such events as the moon landing or 9/11. In this case, the algorithm might have had the opposite effect, fueling speculation about the cause of the fire and who might be behind it.
It's the latest example of artificial intelligence misfiring—and a sign that we have a long way to go before AI becomes smart enough to understand nuance and context.
In a statement, YouTube explained that the background information—an entry from the Encyclopedia Britannica—was mistakenly placed there by algorithms intended to protect users from fake material that spreads in the wake of some news events.
YouTube's algorithms have a history of misfiring and labeling videos inappropriately. Joshua Benton, director of the Nieman Journalism Lab at Harvard University, noted several in a blog post Monday.
Last fall, for instance, YouTube labeled a video of a professor's retirement from Michigan State University with the Encyclopedia Britannica entry for "Jew," along with a Star of David placed under the image. The professor, Ken Waltzer, had been head of the university's Jewish studies program, but Benton noted that nothing in the video's title or description mentioned anything Jewish.
YouTube's algorithm, which is presumably primed to bat down anti-Semitic conspiracies, somehow did that on its own.
When YouTube announced its anti-conspiracy efforts last summer, it said it would counter bogus information with sources people generally trusted, such as Wikipedia and Encyclopedia Britannica. It said it would add background from these sources to videos that feature common conspiracy subjects (for example, vaccinations, school shootings or the 1995 Oklahoma City bombing), regardless of whether the videos supported a conspiracy theory.
Videos of the Notre Dame fire were shown by large, trusted news organizations. YouTube's artificial intelligence, however, made no exceptions.
On Monday, the company quickly fixed the Notre Dame error and said its systems "sometimes make the wrong call." It turned off the information panels for the videos of the fire but did not say whether it was looking at the practice more broadly.
"I think they are sort of back and forth about how much good this is doing," Benton said. "It does get at the core question that we see with Facebook and YouTube and any other tech platform that aspires to global scale. There is just too much content to monitor and you can't have human beings monitor every video."
Instead, we have machines that are clearly still learning on the job.
"It's one thing to get something wrong when the stakes are low," Benton said. "When it's the biggest news story of the world, it seems like they could have more people looking at it."
