Lets say, fact checking sites like Snopes or Politifact have already published their own fact-checking of Eric’s post. This new capability would allow you, as a reader, to use Snopes to filter your own feed. In that case, you would have seen that story labeled as false even before Eric retracted it. Someon…
Good concept, though you’d need a significant amount more fact checking sites for it to be practical. Snopes is good, but it can only cover a very limited amount of stories a day (which I’d guess is maybe about 1% of the questionable news shared online).
At the end of the day, we need a service which is like Snopes, but scales much better. A couple of people checking stories in their free time (or even for their day job) just isn’t enough in today’s world.
