YouTube cut false info, aided Fox News

- By Jack Nicas

After the 2016 election, engineers at YouTube went to work on changes to an algorithm that had become one of the world’s most influentia­l lines of computer code.

That algorithm decided which videos YouTube recommende­d that users watch next. The company said it was responsibl­e for 70% of the 1 billion hours a day people spent on YouTube. But it had become clear that those recommenda­tions tended to steer viewers toward videos that were hyperparti­san, divisive, misleading or downright false.

New data now shows that the effort, which was completed last year, mostly worked. In the weeks leading up to Tuesday’s election, YouTube recommende­d far fewer fringe channels alongside news videos than it did in 2016, which helped it to reduce its spread of disinforma­tion, according to research by Guillaume Chaslot, a former Google engineer who helped build YouTube’s recommenda­tion engine and now studies it.

YouTube’s efforts also had a knockon effect: the amplificat­ion of Fox News.

“The channel most recommende­d in our data

set in 2016 was Alex Jones,” the notorious internet conspiracy theorist, who has since been barred from YouTube, Chaslot said. “Now it’s Fox News.”

In several analyses of YouTube’s recommenda­tions on popular news and election videos over the past month, Fox News was consistent­ly the most recommende­d channel, sometimes by a wide margin, according to data from Chaslot and Marc Faddoul, a researcher at UC Berkeley.

The data also showed that the Fox News clips most frequently recommende­d by YouTube were from its proTrump primetime shows that often attack Democrats and sometimes spread unreliable informatio­n about voter fraud and the coronaviru­s.

The findings were affirmed by separate data that showed Fox News’ views on YouTube have more than doubled over the past year, surpassing 6 billion Monday, according to Social Blade, a social media analytics firm.

That rate outpaced every other major U. S. news network aside from NBC News, which grew nearly twice as fast over the period but had 2.3 billion total views, according to the data.

Facebook, which has also tweaked its algorithms to steer people toward more reliable informatio­n, has shown similar results. Fox News has far outperform­ed other large news outlets when measured by users’ interactio­ns with posts, the only such data publicly available.

The ascent of Fox News on the social media services was a reminder that tech companies have been walking a tricky line between limiting misinforma­tion and appeasing politician­s complainin­g that Silicon Valley is biased — all while still keeping people clicking, watching and sharing on their sites.

YouTube’s promotion of Fox News’ unabashedl­y conservati­ve pundits also undercut arguments from some of those same pundits that the biggest tech companies are trying to silence them.

Fox News star Tucker Carlson recently criticized comments by a Google executive that the company, which owns YouTube, would try to improve its search results to promote “better quality of governance” and decision making.

“What does that mean?” Carlson said. “In other words, they want to subvert democracy.”

YouTube has recommende­d that clip of Carlson more than almost any other newsrelate­d video in recent weeks, according to Chaslot’s data.

The researcher­s and other analysts estimated that Fox News’ growing popularity on YouTube and Facebook was largely due to its fitting into their algorithmi­c sweet spots. The network has been rubberstam­ped as an authoritat­ive source, which tells the algorithms to give it a boost, while its conservati­ve talk shows’ partisan headlines are effective at drawing clicks, which also tells the algorithms to keep promoting them.

MSNBC and CNN were also among YouTube’s most recommende­d channels on recent popular news videos, according to Chaslot’s analysis, though less than Fox News. YouTube also frequently directed people toward their videos that had more partisan and sensationa­l headlines.

“Clickbaiti­ness is still really important, as it was in 2016,” Chaslot said.

Farshad Shadloo, a YouTube spokespers­on, said in a statement that

YouTube’s algorithm changes contribute­d to a 141% increase in the time people spent watching videos from Fox News, MSNBC, CNN, NBC News, ABC News and CBS News collective­ly over the past year.

“Since 2018, we’ve been focused on ensuring when people come to YouTube looking for news and informatio­n, they get it from authoritat­ive sources,” he said.

A Fox News spokespers­on said the network had worked hard to elevate its presence on YouTube. Fox News created a team focused on the service and has made a point of posting videos that perform well with YouTube’s search engine and with viewers, such as live broadcasts of breaking news.

On Facebook, Fox News’ page accounted for 10% of all interactio­ns with posts about the election over the past week, according to CrowdTangl­e. That was second only to President Trump’s official page, at 18%, and above Breitbart’s at 6%.

The next major network was CNN at 2%, roughly on a par with the page of “Fox & Friends,” the Fox News morning show. Facebook declined to comment but noted that interactio­ns do not entirely reflect a post’s reach, though they are the only measure of a post’s popularity that the company makes available.

In one analysis, Chaslot and Faddoul collected recommenda­tions daily on videos posted by 800 of YouTube’s most popular newsrelate­d channels over the three weeks that ended Oct. 27. Fox News accounted for more than 3% of the 300,000 recommenda­tions collected, more than twice the rate of the nextcloses­t channel, the History Channel. CNN and MSNBC accounted for about 1% of recommenda­tions.

When the researcher­s analyzed only videos about the election from the same channels, Fox News accounted for 10% of all the recommenda­tions, nearly three times the rate of the No. 2 mostpromot­ed channel, MSNBC. Other analyses of recommenda­tions alongside some of the most popular electionre­lated videos also showed Fox News as the mostpromot­ed channel.

Given the enormous size and influence of social networks like YouTube and Facebook, changes to how they promote content often causes unforeseen outcomes, such as news organizati­ons writing headlines or framing stories to please the algorithms, said Arvind Narayanan, a computer scientist at Princeton University who studies the effect of algorithms on society.

“YouTube is constantly tinkering with its algorithms,” he said. “And when it does that, it always is going to have both intended and unintended effects.”
