Politicizing Science Causes Both Liberals and Conservatives to Distrust Science

The media often presents conservatives as anti-science and liberals as pro-science. But, that isn't true. Both groups tend to oppose scientific theories that are different than their worldviews.

A recent article published in The Annals of the American Academy of Political and Social Science describes an experiment in which liberals and conservatives were given scientific information on climate change and evolution (pro-liberal worldview) and fracking and nuclear energy (pro-conservative worldview) as well as two neutral topics on astronomy and geology.

They found that both liberals and conservatives begin to distrust science when the information involves issues where the science is opposed to their opinions.

Brian Resnick of National Journal explains:
In the nuclear-energy-fracking condition, liberals "had a more negative emotional experience than conservatives, resisted the information more than the conservatives," [Erik Nisbet, a communications researcher at Ohio State University] says. They also indicated a lower trust in science than the liberals in the ideological neutral condition (the geology-astronomy condition). That's right: When liberals are confronted with topics they tend to disagree with, they begin to distrust the science.
"The difference between liberals and conservatives is not that one has biases and one does not," Nisbet says. "It's that we may have biases against specific topics." Conservatives may be seen as antiscience, but that perception arises because scientific topics that are most often discussed are those that most readily offend the conservative worldview.
When conservatives read about evolution or climate change, they too reacted negatively, but their reactions were stronger (i.e., more negative). Nisbet says that could be because climate change and evolution are more salient in everyday discussions than fracking and nuclear power.
The really bad news for anyone who loves science is not hard to guess. Politicizing science makes people, liberals and conservatives, generally more distrustful of all science on politicized subjects.
More troubling, Nisbet finds evidence that political discussion on scientific issues may make everyone more skeptical of science. Even liberals, who reported they believe in climate change and evolution, were more skeptical of science in the climate-change-evolution condition than in the neutral geology-astronomy condition. "Both liberals and conservatives had lower trust in science after the exposure to that information," Nisbet says. "Politicizing science may reduce trust for everybody, because it starts raising questions over whether science is being used for political reasons on one side or another."
[There's also an interesting video presentation at the end of Resnick's article in which he talks about the differences in the brains of conservatives and liberals when they think.]

Okay, these are contradictory statements (unless I'm missing something). It seems that the second statement should read: "They also indicated a lower trust in science than the conservatives..."

Otherwise, it makes no sense to me.

I do, however, tend to agree with the overall finding that people (especially liberals) are skeptical of material that's at odds with their personal views. It's an interesting piece.

Absolutely right, Max. This part was poorly written. Resnick left out the change from liberals to conservatives and then back to liberals.

I think he was saying that the study showed that conservatives overall had less trust even in neutral science because more of the politicized issues are done against conservative beliefs, and that taints all science a bit. But, that both camps lose trust in science when it is politicized. Thus, the liberals had lower trust in the global warming/evolution science even though they agree with it than in neutral science because they know it is politicized.

If that makes any sense.
