Researchers at George Mason University and Yale broke down U.S. public opinion into six different categories
, based on people’s belief in, and concern about, global warming.
For the nickel version, see the graphic below:
Of course, I’m sure there are more than six ways of slicing this pie. It seems likely to me that public opinion lies in a continuum, rather than in six discrete groups.
Still, the authors’ analysis yields some interesting findings. My favorite is this: folks who are convinced that global warming is a hoax—the “Dismissives”—admit they haven’t thought all that much about the issue (see Figure 6 on page 14 of the pdf) yet rank themselves as extremely knowledgeable and well informed (see Figure 7).
That should tell us something: for many climate skeptics, facts don’t matter much. They’ve only given the subject a bit of thought, but are still convinced that they know the answers. I don’t mean to be snarky, but to me this suggests that some “Dismissives” may suffer from some version of the Dunning-Kruger effect—the idea that people are very poor judges of their own incompetence. That probably makes many “Dismissives” unreachable: when facts confront their biases, the facts bounce off and the biases stand firm. (I’m sure that’s true of us all, to some degree or another.)
