Many decisions about science policy are made not through decision or analysis but on ideological and political grounds. - Chris C. Mooney

In part, the divorce of science and politics can be explained by the very different worldviews that inform each field.

The Right’s war on science also spreads a massive amount of misinformation, and sometimes even fosters outright ignorance. Consider the creationist quest to thwart the teaching of the theory of evolution to public school children. Science has managed to answer one of the most profound questions around—where does the human species come from?—but religious conservatives don’t want anyone to know about it. And with the spread of ignorance and pseudoscience comes a decline in critical thinking—a lapse in our collective capacity to cut through all the lies and distortions and determine which ideas we should trust.

To be sure, it remains up to policymakers to decide whether the economic costs of such preventative measures outweigh the benefits. But that key question isn’t even being properly debated. Instead, climate change has become an issue on which conservatives have elected to fight over science at least as much as over economics, relying on stunning distortions and a shocking disregard for both expertise and the most reputable sources of scientific assessment and analysis.
If this situation is maddening, it is also tragic. There may be no other issue today where a corruption of the necessary relationship between science and political decision-making has more potentially disastrous consequences. And together, James Inhofe and the Bush administration have made that corruption systematic and complete. Not only do they strive to prevent the public from understanding the gravity of the climate situation, but in sowing confusion and uncertainty, they help prevent us from doing anything about it. And this—this—is what the Right calls “rational, science-based thinking and policy-making.”
