Compared to other groups, conservatives have least confidence in science

In the US, science has become a bit of a political punching bag, with a number of presidential candidates accusing climatologists of fraud, even as state legislators seek to inject phony controversies into science classrooms. It's enough to make one long for the good old days when science was universally respected. But did those days ever actually exist?

A new look at decades of survey data suggests that there was never a time when science was universally respected, but one political group in particular—conservative voters—has seen its confidence in science decline dramatically over the last 30 years.

The researcher behind the new work, North Carolina's Gordon Gauchat, figures there are three potential trajectories for the public's view of science. One possibility is that the public, appreciating the benefits of the technological advances that science has helped to provide, would show a general increase in its affinity for science. An alternative prospect is that this process will inevitably peak, either because there are limits to how admired a field can be, or because a more general discomfort with modernity spills over to a field that helped bring it about.

The last prospect Gauchat considers is that there has been a change in views about science among a subset of the population. He cites previous research that suggests some view the role of science as having changed from one where it enhances productivity and living standards to one where it's the primary justification for regulatory policies. "Science has always been politicized," Gauchat writes. "What remains unclear is how political orientations shape public trust in science."



Examining other demographic trends, Gauchat noted that the only other group to see a significant decline over time is regular churchgoers. Crunching the data, he states, indicates that "The growing force of the religious right in the conservative movement is a chief factor contributing to conservatives’ distrust in science." This decline in trust occurred even among those who had college or graduate degrees, despite the fact that advanced education typically correlated with enhanced trust in science.

One challenge with interpreting these results is that science is not a monolithic thing, and the survey was not able to capture which aspect of science (if any) was responsible for the loss of confidence. To use examples provided by the author, it's possible to retain trust in the scientific method, but have lost trust in the research universities where science typically takes place. Conservatives have generally viewed these as bastions of a liberal elite, which may explain part of the trend.

Another potential problem is the relative value people give to the knowledge produced by science (compared to, say, their own intuitions). Gauchat cites other research that suggests that "conservatives were far more likely to define science as knowledge that should conform to common sense and religious tradition." The fact that it sometimes doesn't, then, could also account for some of the decline.

The author also considers what this means in practical terms. In the 1970s, when both liberals and conservatives had equivalently high esteem for science, it may have been possible to enact science-driven policies. "A breakdown of this postwar consensus along sociopolitical lines may signal that the authority of science no longer provides sufficient legitimacy to policymakers and government regulators," Gauchat warns.

That may be true, but there's little evidence that this is what's actually taking place. Politicians are not arguing that we should trust our intuitions when it comes to the climate; instead, they claim that the science has been manipulated. Groups that oppose regulations driven by scientific findings are likewise funding individuals that question the scientific community's conclusions. In other words, nobody is acting like it's politically palatable to simply ignore the science in favor of some other form of knowledge, like intuition.

At least outside of Stephen Colbert. Although if the current trends continue, it's possible that may change.
