NOTE: as of yesterday this Post is up at Climate Etc, the well known Lukewarmer blog of atmospheric scientist Judith Curry: http://judithcurry.com/2015/08/14/climate-culture-versus-knowing-disbelief/
(…and the embedded links pointing to referenced previous posts are set to the Climate Etc. version of these posts).
In a previous post at Climate Etc I showed two analyses on US public attitudes to climate change, based upon data from psychologist Dan Kahan’s studies plus some independent surveys. Both of these seek to explain what social / psychological mechanisms are driving the observed attitudes. The first analysis is Kahan’s own, which concludes that identity defense by adherents of particular political views / parties is the chief mechanism explaining the data, of which ‘knowing disbelief’ is the strongest form exhibited by those Conservatives / Republicans who are science aware. The second analysis, mine, demonstrates that the concept of a ‘climate culture’ provides a much better fit to the data, a culture that has adherents in its own right plus asymmetrical alliance with politics; also that Kahan’s conclusion is largely a product of his own bias due to a major influence from this same climate culture.
For some time before the above post was published (Jan 30th), I’d been looking out for a particular kind of survey that ought to provide significant evidence supporting either one or other of the above analyses. Unfortunately there seemed to be no such survey measuring the group I was interested in, so I had to run without this. However I noticed in June that a Gallup poll (G1) had appeared at the end of March, which while not ideal does measure a superset grouping in an appropriate enough manner to provide useful insight. This new poll data matches closely what the ‘climate culture’ hypothesis expects, and I believe it strongly challenges the ‘knowing disbelief’ hypothesis. While G1 covers respondents from the full US political spectrum, the most insightful data comes from the Independents. The next section is thus helpful context for understanding this data. (Note: for new readers wanting a short-cut, or prior readers wanting a refresher, there’s a compressed summary of Kahan’s theory versus mine in the ~700 word Appendix). Continue reading →
