I fear we are entering the misinformation stage of this election. Lots of smart folks have studied how to combat misinformation. Here are four key points to effective fact-checks:
They are from highly credible sources (with extra credit for those that are also surprising, like Republicans contradicting other Republicans or Democrats contradicting other Democrats).
They offer a new frame for thinking about the issue (that is, they don’t simply dismiss a claim as “wrong” or “unsubstantiated”).
They don’t directly challenge one’s worldview and identity.
They happen early, before a false narrative gains traction.
