A new study looks at how ideological and political beliefs affect people’s perceptions of the weather. The authors surveyed 8,000 people across the U.S. between 2008 and 2011 and found that while floods and droughts were remembered correctly, temperature changes were a different story. From Ars Technica:
In fact, the actual trends in temperatures had nothing to do with how people perceived them. If you graphed the predictive power of people’s perceptions against the actual temperatures, the resulting line was flat—it showed no trend at all. In the statistical model, the actual weather had little impact on people’s perception of recent temperatures. Education continued to have a positive impact on whether they got it right, but its magnitude was dwarfed by the influences of political affiliation and cultural beliefs.
And those cultural affiliations had about the effect you’d expect. Individualists, who often object to environmental regulations as an infringement on their freedoms, tended to think the temperatures hadn’t gone up in their area, regardless of whether they had. Strong egalitarians, in contrast, tended to believe the temperatures had gone up.
