The new skepticism

I was reminded this morning in thinking about things like climate change and evolution how starkly different the certitude level on issues in "pure" politics (like war, foreign policy and economic policy) is from scientific issues. I was thinking about how King W will come out and feign cautious, wise skepticism to reserve judgment on things like whether humans are causing global warming and on ID-creationism. The way these issues are framed appeals to American's sense of fairness and objectivity - "let's sit down and discuss all the rational possibilities, and at the end of it, since these issues are so complicated, we'll still have uncertainty, and thus cause for further debate," this frame says. And conservatives love to toe the party line on this in all discussions about climate change and evolutionary biology.

But look how starkly different these conservatives are when asked to discuss the realities of the Iraq war and our general muscular, hawkish foreign policies, or economic policies. Then, "debate" is not so welcome, and instead you become a terrorist sympathizer or a limp-wristed sissy whose idealitistic notions deserve the label of "flower child"...

Scientists have always been promoters of skepticism. The scientific method is conducive to doubt, as its goal is to provide explanations for natural phenomena which have been thoroughly tested in an effort to debunk their validity. Most of the progress we make in science, contrary to public misconception, is based on what we prove wrong. For example, if I have a hypothesis about how a cell regulates its own MAPK proteins, and I test it and falsify it, then we have progress in the form of eliminating possible rational answers. Cumulatively, these falsifications build up until there are only so many rational alternatives left, and these become, if you will, scientific orthodoxy. But even the most hardened orthodoxy, it is understood, is still subject to modification: that's the beauty of scientific knowledge -- it can always be improved and progress is the goal, not just a possibility.

All that said, I want to point out that it is this very tentative nature of science which those who want to exploit the lack of dogma seize on. Any "controversy" in science, real or imagined, can be created because people understand that a white lab coat is not the same thing as a Roman collar -- our lack of dogma makes it easy to challenge the status quo and current thinking. We eschew rigidity and faith in favor of evidence and questioning.

Those with agendas have exploited this feature of science to no end, emphasizing the fact that "all the facts are never in" -- that it is always possible to find new data that would modify our current interpretations of existing data. Sharon Begley explores this theme in climate change at length in an August Newsweek article, "The Truth About Denial". She carefully chronicles the years-long efforts on the part of energy and oil companies to inject doubt into the mainstream American consciousness about the science behind climate change. It is a powerful strategy, and difficult to overcome.

Just yesterday, I had a surprising conversation with a science teacher who told me that both she and her husband are "climate skeptics". I started a conversation with her, and she told me that the sorts of scientific issues she feels are unresolved involve such things as Mars warming and the decay of the magnetic field of the earth. What was amazing to me was that, although her degree and background are in mathematics and not physics, she certainly had the available faculties to look up and investigate the veracity of these objections for herself, but hadn't. I found out that she had heard this somewhere (Faux News, probably), and had simply believed her source enough not to even go check it out. Little did she know that scientists have addressed all these possible alternative explanations for years, and that they have all been found lacking in merit for various technical reasons.

I really recommend the following index and "guides" for point-by-point refutations of the common objections to man-made climate change:

• The IPCC AR4 report FAQ section (pdf)
  
• Coby Beck's How to talk to Global Warming Skeptic
• New Scientist: Climate Change: A guide for the perplexed
• RealClimate: Response to common contrarian arguments
• NERC (UK): Climate change debate summary
• UK Met Office: Climate Change Myths
• Brian Angliss A Thorough Debunking
• John Cross Skeptical Science

These are all excellent resources with scientific references that should be shared amongst all your friends and colleagues, especially those with whom you think contentious discussions on climate change could take place.

What is so amazing to me is how easily duped people are who feign prudent skepticism towards scientific consensus, but display credulity by swallowing and mindlessly repeating talking points in politics (such as "if we fight them there, we won't have to fight them here" &c.). Is it just that people self-select their news sources in accordance with their pre-determined policy positions, and refuse to budge? Am I the same way? Is it possible to be that way (ignore one side's perspective) if there are actual facts which we can analyze to determine who is right and who is wrong?

Upon further analysis, the president's rationale for invading has been shown a farce and a lie, and every single rationale for the surge and every claim and metric used to support that "the surge is working" falls apart. The central issue of, "Even if we make Iraq 100% safe militarily, that doesn't solve the ethno-sectarian conflict and magically create a unified central government," is continually ignored now, even though Cheney admitted this kept them out of Iraq in 1994.

The numbers get spun in order to keep current policies in place, and people get shuffled when they are no longer willing to spin the right way. As Greenwald recently noted, when Bush is unable to find generals who tell him what he wants to hear, he simply replaces them with those who will. And now, as war with Iran is planned by the right, precipitated by lack of diplomatic progress, and with Faux News dutifully banging the war drums, we need skepticism and cynicism more than ever before. Will it manifest itself? God I hope so.

Why is it that the new skepticism is strongly directed towards scientists, but not towards politics with the same intensity and fervor?
