Michael Tesler presented interesting data that he argued show that elite rhetoric and not motivated cognition accounts for political divisions on climate change. I have a hard time conjuring the psychological model that would see the two operating independently of each other; to me they are not discrete mechanisms, but steps in a process (elite cues help create/transmit the meanings that then motivate cognition for ordinary individuals) & I wasn't sure exactly how the data supported the inference, but I'm eager to see the write up, at which point I'll either get it or explain why I don't think he is right!
Alexandra Bass presented data on media content to show that values influence climate change perceptions. The presentation was great. But I have to say I don't really get media-content studies in general; they seem to draw inferences the validity of which depend on the ratio of frequency of content to frequency of events in the world--something for which the analyses never present any data. I didn't get a chance, though, to read Bass's paper, so I will, & see if that helps me.
Mathew Nowlin, a member of Hank Jenkins-Smith's amazing risk-perception group at theCenter for Applied Social Research at the University of Oklahoma, presented a cool paper on education, climate change knowledge, and politcal polarization.
Finally, Rebecca Bromley-Trujillo backed data out of the American National Election Study to support the hypothesis that "core political values"-- "such as equality"-- "are an important predictor of climate change attitudes, beyond other standard determinants of political attitudes, like partisanship or ideology." I found the cliam convincing, but I was admittedly predisposed to believe it.
