"Climate change e-mail scandal underscores myth of pure science"

From December 16th's L.A. Times.

Very good read and worth your time.

The authors remind us that using science to make political decisions is just as dangerous as using politics to make decisions in which science is needed.  Some selections:

"The real scandal illustrated by the e-mails is not that scientists tried to undermine peer review, fudge and conceal data, and torpedo competitors, but that scientists and advocates on both sides of the climate debate continue to claim political authority derived from a false ideal of pure science. This charade is a disservice to both science and democracy. To science, because the reality cannot live up to the myth; to democracy, because the difficult political choices created by the genuine but also uncertain threat of climate change are concealed by the scientific debate."

"That myth has allowed politicians to shirk their responsibility to be clear about the values, interests and beliefs that underpin their preferences and choices about science and policy. Better to recognize that decision-makers, depending on their political beliefs, will weigh the evidence and risks of climate change differently when evaluating policy options. Their choices will influence the distribution of benefits and costs, and will have varying and uncertain prospects for success. Voters should evaluate the decisions on that basis, rather than on the false notion that science is dictating the choices."

"The choices are extraordinarily difficult; the costs of action, and inaction, are potentially momentous. No one can know what the "right" decisions will be, but the e-mail controversy reminds us that imperfect people, not pure science, must decide that question. This is a job for democratic politics, informed by, but not shackled to, a pluralistic, insightful and imperfect scientific enterprise."

A Thought About Climategate

As the "ClimateGate" situation continues to unfold, there is one reason in particular why this whole hot mess troubles and disappoints me.  As I described to a friend earlier this week, not only has ClimateGate brought into question some knowledge or theory that some of us believed to be truth, it has also cast doubt on the very reasons why we believe what we believe.  As Ilya Somin writes on the Volokh Conspiracy blog, I think we often forget how much "truth" relies on social validation.  The fact that ClimateGate involves scientific knowledge makes the social validation proposition that much more troubling.  I - and I think there are others who agreed with me on this point - believe science to be one of the few terrestrial sources of truth, or something close to it.  I believe this because, while science certainly relies on theory, it strives to validate theory through data.  And, unlike words, numbers are not subject to interpretation.  Five is five - upside down or inside out.  The fickle and fleeting nature of words' meaning is famously illustrated by statements like "It depends on what the definition of 'is' is."  Thus, when circumstances cast doubt on the reliability of numbers, I start to notice little beads of sweat on my brow.
