Create an algorithm that "checks" the fact behind an article and gives the reader a percentage number of how accurate the facts might be.
Realizing the Idea
Gather a bunch of intelligent people in a locked room and tell them to create this algorithm. Don't let them out until they have succeeded.
After that lock the algorithm away so that it cannot be tampered with.
It gives the reader of information on the internet a hint of how well the view or article is base on facts or just on the persons personal view. A persons view is based on culture, parents, upbringing and values, not always on facts.
If google and other search engines can create answers that more or less fit the person that is looking then give them the tool to see how "fact" based the view is.
