Myths and debunking

Quoting Skeptical Science on debunking myths:

Common wisdom is that the more counter-arguments you provide, the more successful you’ll be in debunking a myth. It turns out that the opposite can be true. When it comes to refuting misinformation, less can be more. Debunks that offered three arguments, for example, are more successful in reducing the influence of misinformation, compared to debunks that offered twelve arguments which ended up reinforcing the myth.

For more information, read Schwarz, Sanna, Skurnik, Yoon: Metacognitive experiences and the intricacies of setting people straight: implications for debiasing and public information campaigns.

For commentary on how scientists should respond to denialists, read Diethelm and McKee: Denialism: what is it and how should scientists respond?
