Some good concrete suggestions from @wihbey for countering misinformation in the media if you are a journalist:
1) Find sources within the communities that are susceptible to misinformation but who don’t buy into the misinformation, and quote them in your article.
2) List a conspiracy theory that is gaining traction next to other conspiracy theories that have clearly been discredited or that are more obviously absurd.
3) People often only see the headline of an article, e.g., on social media, so make sure the headline doesn’t muddy the truth.
