from Dan Kahan:
[W]hen positions on a fact that admits of scientific investigation (“is the earth heating up?”; “does the HPV vaccine promote unsafe sex among teenage girls?”) becomes entangled with the values and outlooks of diverse communities—and becomes, in effect, a symbol of one’s membership and loyalty in one or another group—then people in those groups will end up in states of persistent disagreement and confusion. These sorts of entanglements (and the influences that cause them) are in effect a form of pollution in the science communication environment, one that disables people from reliably discerning what is known to science.
The science communication environment is filled with these sorts of toxins on climate change. We need to use our intelligence to figure out how to clean our science communication environment up.
An example or two may help:
How readily and open-mindedly people will engage scientific information depends very decisively on context. A person who hears about the HPV vaccine when she sees Michelle Bachman or Ellen Goodman screaming about it on Fox or MSNBC will engage it as someone who has a political identity and is trying to figure out which position “matches” it; that same person, when she gets the information from her daughter’s pediatrician, will engage it as a parent, whose child’s welfare is the most important thing in the world to her, and who will earnestly try to figure out what those who are experts on health have to say. Most of the contexts in which people are thinking about climate change today are like the first of these two. Find ones that are more like the second. They exist!
Dan’s sciency take on this subject provides a sort of post hoc explanation for why I abandoned the climate wars.
