Months before critics revisited Facebook’s embrace of Holocaust deniers and other conspiracy peddlers, YouTube faced similar pressures. In February, a Wall Street Journal investigation found that Google’s video-sharing site routinely pushed users to misinformation or hyper-partisan content through its automated recommendations. In a widely follow-up in the New York Times, Zeynep Tufekci called Google’s video-sharing site “the great radicalizer.”

Like Facebook, Google is loath to declare any topic off-limits to its user base. And so at South By Southwest, YouTube CEO Susan Wojcicki unveiled a potential solution: “information cues,” a companion product for conspiracy videos that offers users additional, non-crazy viewpoints about subjects like the moon landing and chemtrails. It began rolling out just within the past two weeks, and the company does not yet have data to share about how it’s working, a YouTube spokeswoman said.
