Cl4rify

First crowd-sourced fact-checking tool. Anyone can sign up and make a claim. People are then encouraged to submit evidence to support it or counterevidence to disprove it. This evidence is in the form of studies or articles. You are presented with a form asking for url to the source, authors, year, etc. Citation is automatically generated. People can also discuss and vote. I think it could be a place in the future where you go to get clarity on difficult topics.
