15 Apr 2016: iDEA workshop on debunking myths

At the 2016 annual conference for the Doctors for the Environment Australia, I presented a one hour workshop at the Royal Brisbane Hospital on the psychology of debunking myths. For the first half of the workshop, I explained the psychological research into debunking misinformation, concluding with the Fact-Myth-Fallacy structure of an effective debunking. Then the workshop split up into small groups to develop their own Fact-Fallacy debunking of a myth of their choice. Lastly, each group reported back with what they came up with, which resulted in some fascinating discussion in what was the key "factual alternative" to dislodge specific myths, and what fallacy did the myth employ. The below video features my initial talk on the psychology of debunking, and here are the PPT slides (with the videos removed to reduce file size).
