Want to Sway Climate Change Skeptics? Ask About Their Personal Strengths (And Show Pictures!)
Readers of my posts over the last half year will be familiar with the phenomenon of motivated reasoning, in which people’s subconscious emotional impulses lead them to respond, in a biased way, to information that challenges their deeply held beliefs and worldviews. We’ve been focusing on this so much because I believe it explains a great deal of what we here call climate change denial, and the resistance to inconvenient science (and inconvenient facts) in general.
One important researcher on motivated reasoning is Dartmouth political scientist Brendan Nyhan. In Mother Jones, I described one of his previous studies, demonstrating how motivated reasoning can lead to a “backfire effect” when people are confronted with politically inconvenient information:
Take, for instance, the question of whether Saddam Hussein possessed hidden weapons of mass destruction just before the US invasion of Iraq in 2003. When political scientists Brendan Nyhan and Jason Reifler showed subjects fake newspaper articles (PDF) in which this was first suggested (in a 2004 quote from President Bush) and then refuted (with the findings of the Bush-commissioned Iraq Survey Group report, which found no evidence of active WMD programs in pre-invasion Iraq), they found that conservatives were more likely than before to believe the claim. (The researchers also tested how liberals responded when shown that Bush did not actually "ban" embryonic stem-cell research. Liberals weren't particularly amenable to persuasion, either, but no backfire effect was observed.)
So how do you persuade people, if not with factual corrections of the sort run by newspapers? That’s what a new paper by Nyhan and Reifler has undertaken to study.
