Science denial has significant consequences. AIDS denial caused over 300,000 deaths in South Africa. Vaccination denial has allowed preventable diseases to make a comeback. Climate science denial helped delay sorely needed mitigation policies, committing us to direr climate impacts for decades to come.
Skepticism (by which I mean an evidence-based approach) is the antidote to denial. But skepticism doesn’t just apply to how we practice our science. It must also apply to how we communicate our science. There is a wealth of psychological research into the phenomena of denial and how to neutralize the influence of misinformation. To ignore this evidence when countering science denial and pseudoscience is, ironically, not a skeptical approach.
So what is an evidence-based response to science denial? To illustrate, allow me to use an example from my own area of research: the scientific consensus on climate change. The psychological principles emerging from this topic have implications that can be applied to many areas of science.
