I've been wondering for quite some time why you see the same "scientists" on the denial side for every science related issue: tobacco, climate change, ozone, cancer, acid rain, whatever. There are some easy answers, money, fame, attention, and you know some of the easy answers make sense, but there is also something deeper that needs to be thought about. I know scientists in senior positions who are politically far, far to the right of George Bush, but they are very straight on their science. I can disagree with their science, and we talk about the scientific reasons for their opinions and mine. They go where the facts are on science and I do too. I know some scientists whose politics are on the left, in senior positions who let their politics creep into their science or at least the policy related parts of it, but they confine their science to their own areas, and don't try to be polymaths (the big exception would be Noam Chomsky). In any case, this needs more thought and research.
Recently I started to get into the issue in comments on Prometheus. Steve Hemphill played interlocutor. I said that Singer, Seitz and Lindzen, were for reasons I didn't much understand, into both tobacco and climate denial and pointed to the tobacco document depository, the trove of documents uncovered in litigation about how the tobacco industry suppressed information about the health effects of their products and used public relations campaigns to confuse the issue. It was trivial to show that Frederick Seitz was a key player, but Steve Hemphill keeps trying to play nyah, nyah and wanted evidence that Fred Singer was also involved (The poster hank on Prometheus showed that Lindzen is one of those who denies the ill effects of environmental tobacco smoke). I spent some time last night going through the tobacco documents and came upon this interesting set which definitively illuminates the astroturf industry at its most effective
S. Fred Singer played a key role in their attempts to deny the harm from environmental tobacco smoke (ETS)
Here is the man who will handle the EPA/ETS (illegible) work Brennon wants for us on the “social costs". Very impressive resume. I think the project is worth the 20K we discussed. Agree?.
On behalf of the directors of the Alexis de Tocqueville Institution, I would like to thank the Tobacco Institute for its grant of $20,000 to support our research and education projects. IRS regulations require us to inform you in writing that we received your tax deductible $20,000.00 donation (check # 016214) today.
DRAFT ONLY The EPA and the Science of Environmental Tobacco Smoke Introduction by S. Fred Singer and Kent Jeffreys
In 1994 Cesar Conda was executive director of the Alexis de Tocqueville Institution listed as "Senior Staff and Contributing Associates" on a Lorillard Tobacco Company paid-for publication titled "Science, Economics, and Environmental Policy" by author Kent Jeffreys.  Principal Reviewer was listed as S. Fred Singer, and to give this propagandistic tract a sheen of scientific appearance, a loaded gang of "experts" from assorted tobacco-funded front organizations with impressive names was listed: SEPP, Hoover Institution, John M. Olin Center for Policy, George Mason University.
