Merchants of Doubt: How a Handful of Scientists Obscured the Truth on Issues from Tobacco Smoke to Climate Change Paperback – May 31, 2011
Purchase options and add-ons
Featuring a new Foreword by former Vice President Al Gore
Finalist for the Los Angeles Times Book Prize
"Important and timely. We ignore this message at our peril."-Elizabeth Kolbert
Merchants of Doubt has been praised-and attacked-around the world, for reasons easy to understand. This book tells, with “brutal clarity” (Huffington Post), the disquieting story of how a loose-knit group of high-level scientists and scientific advisers, with deep connections in politics and industry, ran effective campaigns to mislead the public and deny well-established scientific knowledge over four decades. The same individuals who claim the science of global warming is “not settled” have also denied the truth about studies linking smoking to lung cancer, coal smoke to acid rain, and CFCs to the ozone hole. “Doubt is our product,” wrote one tobacco executive. These “experts” supplied it. Merchants of Doubt rolls back the rug on this dark corner of American science. Now with a new Foreword by former Vice President Al Gore, and with a new Postscript by the authors.

- Reviewed in the United States on June 8, 2013I came across this book after reading two books on the science of climate change. I, therefore, was familiar with the denial movement's efforts to quash the science in that case. Merchants of Doubt showed me just how this phenomenon was not just an issue with climate science but with many other facets of science. Oreskes and Conway summed it up nicely saying, "Doubt is crucial to science - in the version we call curiosity or healthy skepticism, it drives science forward - but it also makes science vulnerable to misrepresentation, because it is easy to take uncertainties out of context and create the impression that everything is unresolved." This is their culmination of five years of research.
The authors begin, by explaining the doubt that was sowed by the tobacco industry. I think we are all familiar with the manner in which the industry tried to persuade the public that smoking and second hand smoke were not dangerous. This continued on with the Strategic Defense Initiative during the Regan administration where a coordinated attack was made on the concept of a nuclear winter as proposed by Carl Sagan and others. This marked a period where "the right-wing turn against science had begun." The attack on nuclear winter was a prelude to the fights that were to come. Continuing to the subject of acid rain, the authors noted a familiar pattern emerging, and that was that scientific facts were published in peer review scientific journals - where few non-scientists would see them - while all the claims that acid rain was not a problem pushed by the deniers ended up in the mainstream media for all to see.
The next topic was the fight over the ozone hole. The authors explained in detail the counter narrative proposed by the ozone hole deniers despite all the scientific evidence to the contrary - that the ozone depletion was a natural variation "that was being cynically exploited by a corrupt, self-interested, and extremist scientific community to get more money for their research." Really? - no, of course not. This was to be the narrative to be used by the global warming deniers as well. During the 1980s, "an anti-environmentalism had taken root in a network of conservative and libertarian think tanks in Washington," such as the American Enterprise Institute, the Heritage Foundation, the Marshall Institute, and the Competitive Enterprise Institute. These institutes derived their support from businessmen, corporations, and conservative foundations. What the deniers were afraid of was anything that impeded the free markets and the capitalist system, or that caused the government to produce any kind of regulation that might affect business interests according to Fred Singer, a prominent individual in the denier movement.
I particularly liked the section on global warming, having just read two books previously on this "seemingly" controversial subject. The authors show that there is, in fact, no controversy; the climate scientists are correct in their assessments - yes, really! It was the small number of key people, such as Seitz, Jastrow, Nierenberg, and Singer who engaged in a campaign of misinformation, and these people, along with others, can "have large, negative impacts, especially if they are organized, determined, and have access to power." These men had the power by virtue of positions as physicists during the cold war era. This movement has turned into a stealthy financed, powerful, conglomerate of various organizations bent on attacking the science in order to achieve various political and industry goals.
And now we turn our attention to Rachel Carson and her book Silent Spring. This book was written in 1962. I have heard the harsh criticism - bordering on contempt - against her by various right-wing media outlets, and I wondered what in the world this woman did over fifty years ago, and why is this decades old debate being reopened. The authors brilliantly cleared up my questions. You might know that Carson brought attention to the indiscriminate use of pesticides in the environment. Eventually, about ten years later, a ban was implemented by Richard Nixon. This turned out to be an example of regulation done well, based on several national level science assessments that confirmed the dangers of the persistent chemical DDT. Well, as the authors point out, "free marketers realized that if you could convince people that an example of successful government regulation wasn't, in fact, successful - that it was actually a mistake - you could strengthen the argument against regulation in general." Also noted is that the environmental movement was shifting from an aesthetic environmentalism towards one more oriented in favor of legal regulation. Ah, now we know why this matter is in the news, and why the attack on Carson. Carson's input was fundamental to this reorientation. If Carson could be proved wrong, then perhaps this reorientation could be shown to be based on a fallacy, and the anti-regulatory powers that be could be vindicated. I don't want to leave out that the authors make a very compelling case showing why DDT failed and why it did not lead to "millions of deaths" as claimed by people such as Steve Milloy (founder of The Advancement of Sound Science Coalition for Philip Morris) and J. Gordon Edwards (entomologist at San Jose State University) - a phrase that is now repeated by right-wing media outlets. This was a riveting chapter. It read like an intriguing suspense novel!
I found the next chapter on free speech and free markets to be just as riveting. Many of these deniers believe in something that has been called "free market fundamentalism." This basically says the free markets are the only way to run an economic system that will not ultimately destroy our freedoms. However, the authors note that this belief system is uncannily similar to its bête noir - Marxism. They say that like Marxism, laissez-faire economics claimed to be scientific, based upon immutable laws of nature, and also like Marxism, it has not stood the test of experience. If it were a scientific theory, it would have long ago been rejected." They conclude that this fundamentalism is just an article of faith. But it is this "faith" that has resulted in these "fundamentalists" coming to the unbelievable notion that environmentalism is the next great threat to freedom, that it is a slippery path to socialism, that environmentalists are closet socialists, that people in the United Nations are connected to the International Socialist Party and they are the ones in the UN environmental program. I read this and said to myself: Wow, really! It appears that the Cold War Warriors (Jastrow, Seitz, Nierenberg, and others) needed a new threat and found it in environmentalism. But as a more in depth analysis shows, it is all about government regulation; anything that promotes more regulation, even if necessary, is anathema to these people, and, I might add, to the businesses that fund them. The sad part is the nature of the attacks on scientists doing good science. Some have become reluctant to make strong claims or err on the side of conservatism because of fear of attack. It seems that intimidation works. I could go on, but you'll just have to read the book to get the full story.
I highly recommend this book. It does an excellent job of clearing the fog of misinformation that seems so pervasive today. If you have any lingering doubts on any of these subjects or if you wonder what the truth of the matter is in each case, please read the book.

5.0 out of 5 stars A critically important book that everyone must read - especially climate skeptics
This book made me angry. And it should make you angry as well. The title "Merchants of Doubt" comes from the same line from a tobacco company executive used in a similar book that came out a couple of years ago that I recently reviewed (Doubt is Their Product). The basis, first used by the tobacco industry many years ago, was that their goal was to "manufacture doubt" in the minds of the public and policy-makers so that no policy-making action would occur, or at least so that it should be delayed as long as possible. And the tobacco industry succeeded for decades after they themselves knew that tobacco/nicotine was addictive and caused cancer. Yet they carried on a well-funded campaign to confuse and disinform the public.
Naomi Oreskes and Erik Conway are science historians. And what they have uncovered with this book should shock even those who are familiar with some of the tactics used by the professional denialist industry. What is even more shocking is how just a handful of scientists and their collaborators have had a hand in nearly every major science denial episode for the last 40 years. And in the center of it all is the George C. Marshall Institute, Fred Seitz, S. Fred Singer, and the lesser known but equally deceptive William Nierenberg and Robert Jastrow.
After the tactics were perfected in the fight to deny that smoking causes cancer, these handful of men with close ties to the Reagan and conservative ideologies employed them over and over again to deny smokestack emissions cause acid rain, CFCs cause ozone depletion, second hand smoke cause cancer in non-smokers, and greenhouse gas emissions cause global warming. In all cases the science has been right, and this group of men helped delay action for many years until even their deceit couldn't hide the truth.
And those tactics, repeated to deny the science in each of these issues, were all the same: employ a few scientists willing to shill for the industry or who are "skeptical" (to create the illusion of credibility), focus the efforts through well-funded right wing think tanks (to create the illusion of independence), create "new" science specifically designed to create uncertainty (i.e., not to answer questions, but to create contrasting data they can misrepresent), hyperventilate about how "the science is not settled" (knowing that science is never settled, but the public won't understand), and of course, using their PR skills, Frank Luntz wordsmithing, and punchy - though meaningless - catchphrases like "sound science" to make it sound like they are saying something when they are not saying anything.
What I found amazing was how the origins of the George C. Marshall Institute and all of its subsequent science denialism came out of the cold war fight against communism. These handful of scientists were atomic bomb builders and astrophysicists who had no expertise in any of the science they were denying. But they had connections, most notably with the Reagan administration and the Strategic Defense Initiative (Star Wars) for which the George C. Marshall Institute was started to sell to the public, the military, and the conservative legislators they were trying to influence. Yet despite this lack of any expertise they continued to insert themselves into the acid rain debate, the CFC debate, the second hand smoke debate, and the climate change debate. And each and every time their goal was to push the denial of the science. They equated environmentalism with communism ("green on the outside, red on the inside"). And using their lobbying skills and influence they were able to create the impression that there was still a raging debate in the science, even though in all cases the science was overwhelming and they represented a very minority opinion. Actually, in all cases they were not being scientists at all, but rather advocates for non-action (all of these men had long-since stopped doing actual research, and none of them had ever done research in the areas of science they were denying).
What is most disturbing is that they routinely employed unscientific methods and deceit to push their political views. These handful of men have almost single-handedly cost the lives of thousands of Americans and increased the cost to taxpayers millions or even billions of dollars through their denial of the science. Most egregious in this has been S. Fred Singer. First as a denier that smoking caused cancer, then as a denier that CFCs caused ozone depletion, and now as a denier of climate change, Singer has used despicable methods to deceive fellow scientists who were too slow to realize that such deceit was possible from one of their own. What he did to Roger Revelle on his death bed is disgraceful. What he did to Justin Lancaster is despicable. What he and others did to Ben Santer is just one more example showing that the denialist industry, led by these few men and paid for by the biggest industries on the planet, will go to no end to deny any science or destroy any scientist in their path. The recent attacks on climate scientists like Michael Mann and Phil Jones are the latest iterations in the denialist industry's tactics.
And according to Oreskes and Conway, the denialist industry isn't even satisfied denying the present and the future, they have also recently turned to denying the past. You may have heard parroted from people here that the banning of DDT by environmentalists has killed millions of people in Africa. Not true. But the denialist industry has decided it needs to deny ALL science, and that means going back to the 1960s to attack Rachel Carson, whose book "Silent Spring" documented the dangers of widespread pesticide spraying. DDT was banned in the US after it was discovered that it caused the thinning of eggshells in raptors like our national symbol, the Bald Eagle. But like all the other denialist attacks, the idea that the US ban cost lives in Africa is completely false. DDT use actually increased in Africa after it was banned in the US, and in fact is still used today. It just doesn't work any more because the mosquitoes it is supposed to kill gained resistance to it, in part because of the overspraying advocated by the manufacturers to sell more product. But this is just one more case where facts are tossed aside in favor of an ideological promotion of an anti-science agenda designed to further the profit of the few at the expense of the many.
Oreskes and Conway end their book with "A New View of Science," which I'll let people read for themselves. And they should. In fact, they must. This book must be on the reading list of anyone and everyone interested in science, so they can read for themselves how just a handful of unscrupulous scientists with deep political connections and a near religious anti-communism fervor have been at the heart of every denial of science in the last several decades. As I indicated to open this review, the book made me angry. And we should be angry. And then we should not let them get away with it any longer.
