...I want to pause here and talk about this notion of consensus, and the rise of what has been called consensus science. I regard consensus science as an extremely pernicious development that ought to be stopped cold in its tracks. Historically, the claim of consensus has been the first refuge of scoundrels; it is a way to avoid debate by claiming that the matter is already settled. Whenever you hear the consensus of scientists agrees on something or other, reach for your wallet, because you're being had.
Let's be clear: the work of science has nothing whatever to do with consensus. Consensus is the business of politics. Science, on the contrary, requires only one investigator who happens to be right, which means that he or she has results that are verifiable by reference to the real world. In science consensus is irrelevant. What is relevant is reproducible results. The greatest scientists in history are great precisely because they broke with the consensus.
There is no such thing as consensus science. If it's consensus, it isn't science. If it's science, it isn't consensus. Period.
...Finally, I would remind you to notice where the claim of consensus is invoked. Consensus is invoked only in situations where the science is not solid enough. Nobody says the consensus of scientists agrees that E=mc2. Nobody says the consensus is that the sun is 93 million miles away. It would never occur to anyone to speak that way.
...Yet for most people, the fact that nuclear winter was a scenario riddled with uncertainties did not seem to be relevant.
I say it is hugely relevant. Once you abandon strict adherence to what science tells us, once you start arranging the truth in a press conference, then anything is possible. In one context, maybe you will get some mobilization against nuclear war. But in another context, you get Lysenkoism. In another, you get Nazi euthanasia. The danger is always there, if you subvert science to political ends.
...As the twentieth century drew to a close, the connection between hard scientific fact and public policy became increasingly elastic. In part this was possible because of the complacency of the scientific profession; in part because of the lack of good science education among the public; in part, because of the rise of specialized advocacy groups which have been enormously effective in getting publicity and shaping policy; and in great part because of the decline of the media as an independent assessor of fact. The deterioration of the American media is dire loss for our country. When distinguished institutions like the New York Times can no longer differentiate between factual content and editorial opinion, but rather mix both freely on their front page, then who will hold anyone to a higher standard?
And so, in this elastic anything-goes world where science-or non-science-is the hand maiden of questionable public policy, we arrive at last at global warming.
When did "skeptic" become a dirty word in science? When did a skeptic require quotation marks around it?
[Much more begging to be highlighted :^) Absolutely brilliant. If you were postponing to read this article because of it size, be assured that this is the time well invested]
Nailed It!
This ping list is not author-specific for articles I'd like to share. Some for the perfect moral clarity, some for provocative thoughts; or simply interesting articles I'd hate to miss myself. (I don't have to agree with the author all 100% to feel the need to share an article.) I will try not to abuse the ping list and not to annoy you too much, but on some days there is more of the good stuff that is worthy of attention. You can see the list of articles I pinged to lately on my page.
You are welcome in or out, just freepmail me (and note which PING list you are talking about). Besides this one, I keep 2 separate PING lists for my favorite authors Victor Davis Hanson and Orson Scott Card.
