YouTube's recommendation algorithm might have been a key weapon for the far-right to firehose public discourse with disinformation
Next week, Brazilian former President Jair Bolsonaro will go on trial for instigating false claims over electoral fraud. Now, a new study reveals how YouTube's recommendation algorithm might have been a key weapon for him to firehose public discourse with disinformation.
In an effort to study Brazilian YouTube users' perceptions of political content, researchers from Mozilla, Instituto Vero, and Exeter University have detailed how a complex, web-like influencer system of YouTube channels helped shape political narratives during Brazilian elections.
This is in addition to YouTube's own recommendation algorithm, which also generates suggestions based on users' viewing patterns.
