A decades’ experience shows that “Consensus messaging” doesn’t work. – Dan Kahan
Two weeks ago, Bristol University hosted a debate between Stefan Lewandowsky and Dan Kahan [link].
What is the best way to communicate the risks from climate change to the public? Dan Kahan has been championing the idea that risk perception depends on one’s culture or “worldview”, with people on the political right being more likely to downplay the risks from climate change than people on the political left. Stephan Lewandowsky has also found support for this notion in his own research, but he additionally finds that knowledge of the pervasive scientific consensus about global warming is a “gateway belief” that shapes people’s acceptance of the science and their willingness to support mitigation policies. So what are the implications of those two positions? Do they permit synergy or are they locked in opposition? Is there a third way to communicate science?
