Back in 2012, Columbia Journalism Review gave some tips for how the media can try to counter misinformation. It’s hard and nothing is foolproof, but there are some best practices. People tend to believe things they hear repeated, things that meet their preconceived notions, and statements from people and organizations they trust. One best practice is to state the truth in a positive way rather than as the negation of a false statement. Another is to not quote partisan or ideological sources when refuting the false statement. Another is using graphics where possible to give context to numbers.
