Not anyone can use ClaimReview. Google has published rules on who can include the code in their articles, which include things like “discrete, addressable claims and checks must be easily identified in the body of fact-check articles” and “readers should be able to understand what was checked and what conclusions were reached.”
That’s different than what BuzzFeed characterized as YouTube’s “verified fact-checking partners.” YouTube is basically just employing technology that Google is already using to surface fact checks in search results.
It’s also a more hands-off approach to misinformation than that taken by Facebook, which launched a program in December 2016 to individually partner with fact-checking organizations around the world. That initiative relies on fact-checkers to manually debunk discrete posts in a custom dashboard on the site, thereby decreasing false posts reach in the News Feed. (Disclosure: Being a signatory of the International Fact-Checking Network’s code of principles is a necessary condition for joining the project.)
Both Google and Facebook’s approaches to misinformation have been widely cited for their efforts to surface content from fact-checkers. And while the former has not been as widely scrutinized as the latter, it hasn’t been flawless.
In January, an online furor began after Google search results erroneously appended a Washington Post fact check to a story from The Daily Caller. The fact check, which was displayed in Google’s “Knowledge Panel” feature for The Daily Caller — similar to YouTube’s information panels — debunked a statement that was not made verbatim in the outlet’s story.
