Fact checking is a good tool (critical thinking and self-verification would be better). What can save time over time is to know which publications continously publish the most verifiable truths. Albeit always reading with vigilance.
In what way would fact checking be polarizing?
Humans don't act this way and don't respond to it. The media isn't out to inform people through content, but to program people through delivery.
The only result of this will be to have people say "SEE! GOOGLE SAYS IT'S TRUE/FAKE!" And they'll share the headline on Facebook/Twitter and be done with it.
People don't act rationally anymore, especially when it comes to media.
Media outlets have agendas. The press hasn't been free in a long time. https://medium.com/@SarahRRunge/amazon-the-washington-post-a...
