If you click on a highlighted claim on a web page then Dispute Finder will display a popup dialog showing arguments for alternative points of view that you might find convincing.
Of course, different people will disagree on which arguments are trustworthy or convincing. When Dispute Finder shows you an argument, you can vote it up or down to let Dispute Finder know whether you think the argument is interesting.
At present, Dispute Finder largely ignores these votes, but a future version of Dispute Finder will use these votes to predict which arguments it should show you in the future, and which claims have evidence that is most likely to convince you they are disputed.
To add an argument to Dispute Finder, browse to the web page that contains the
argument, select a representative paragraph of text to use as an excerpt, right click,
and select Use as evidence
from the popup menu
