YouTube’s video recommendation system has been repeatedly accused by critics of sending people down rabbit holes of disinformation and extremism. Now Mozilla, the nonprofit that makes the Firefox browser, wants YouTube’s users to help it research how the controversial algorithms work. From a report: Mozilla on Thursday announced a project that asks people to download a software tool that gives Mozilla’s researchers information on what video recommendations people are receiving on the Google-owned platform. YouTube’s algorithms recommend videos in the “What’s next” column along the right side of the screen, inside the video player after the content has ended, or on the site’s homepage. Each recommendation is tailored to the person watching, taking into account things like their watch history, list of channel subscriptions or location. The recommendations can be benign, like another live performance from the band you’re watching. But critics say YouTube’s recommendations can also lead viewers to fringe content, like medical misinformation or conspiracy theories. Read more of this story at Slashdot.
