How to Get a Liberal to Question Global Warming

Readers of my posts will know that I’ve often focused on the work of Yale’s Dan Kahan and his colleagues, who have published fascinating research on how our political and cultural views skew our perceptions of scientific reality. In particular, Kahan et al find that “hierarchical-individualists” (aka conservatives) have very different responses to a variety of facts than do “egalitarian-communitarians” (aka liberals), and that these responses spring not from objective assessments of the evidence, but rather, from deeply seated worldviews that color our perceptions of what is true.

Such research has often been interpreted in a way that has made conservatives look, well, kinda bad. In one Kahan study, for instance, hierarchical-individualists overwhelmingly rejected the very idea that a scientist could be considered a real and legitimate “expert” because of that scientist's opinion that global warming is real and caused by humans. This is not exactly what I would call open-minded behavior.

But the research coming out of the Kahan group is actually quite balanced and does not merely target conservatives. And since I myself am often drawing on these sort of studies to criticize the right, I think it’s only fair to discuss a new Kahan et al study that, if you look closely, appears to show liberals also reasoning in a biased fashion.

[Don’t worry: I still think conservatives have much more deeply rooted issues with science. But it’s a complicated world out there, and it isn’t like liberals and environmentalists are complete innocents all the time. In my view, if we're going to criticize our ideological opponents, we've also got to try hard to see our own blind spots.]

So how do you get liberals to behave in a manner that, at least to my mind, might be called ideologically biased?
