Imagine having several tabs above any web page. Depending on which tabs you click, the entire content of that page gets truncated to display only parts specific to the filters you apply.
For better context, the parts of interest could be highlighted and shown accompanied by a preceding and following sentence.
Some of the tabs I can think of:
high signal, low noise (remove the debates, display only info the reader can work with)
research-backed facts only
highlight the writer's biases
highlight the writer's logical fallacies
On mouseover, the displayed parts could also show the reviewer's rationale - a reason why they were selected.
All the content would continuously be peer reviewed, parts singled out, categorized and and voted upon for approval/rejection. People would have the ability to initiate disputes if they feel something was miscatergorized and needs to be re-reviewed.
This feature would be especially useful for online content where many people can contribute (forums, social media) or news where agenda needs to be removed so that people can see the story for what it is.
