Merchants of Doubt

Merchants of Doubt is a earth science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Merchants of Doubt rather than just read about it. In short: Merchants of Doubt: How a Handful of Scientists Obscured the Truth on Issues from Tobacco Smoke to Global Warming is a 2010 non-fiction book by American historians of science Naomi Oreskes and Erik M. Conway.

Key takeaways

  • Merchants of Doubt belongs to earth science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Merchants of Doubt to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Merchants of Doubt from memory before moving on to harder problems.

Reference excerpt

Merchants of Doubt: How a Handful of Scientists Obscured the Truth on Issues from Tobacco Smoke to Global Warming is a 2010 non-fiction book by American historians of science Naomi Oreskes and Erik M. Conway. It identifies parallels between the global warming controversy and earlier controversies over tobacco smoking, acid rain, DDT, and the hole in the ozone layer. Oreskes and Conway write that, in each case, the overall strategy of those opposing action is to "keep the controversy alive" by continuing to spread doubt and confusion long after a scientific consensus has been reached. In particular, they show that Fred Seitz, Fred Singer, and a few other contrarian scientists joined forces with conservative think tanks and private corporations to challenge the scientific consensus on a wide variety of contemporary issues. Some of the book's subjects have been critical of the book, but most reviewers received it favorably. It was made into a film, Merchants of Doubt, directed by Robert Kenner, released in 2014.

Summary

Oreskes and Conway write that a handful of politically conservative scientists, with strong ties to particular industries, have "played a disproportionate role in debates about controversial questions". The authors write that this has resulted in "deliberate obfuscation" of the issues which has had an influence on public opinion and policy-making. The book criticizes the so-called Merchants of Doubt, some predominantly American science key players, above all Bill Nierenberg, Fred Seitz, and Fred Singer. All three are physicists: Singer was a space and satellite researcher, whereas Nierenberg and Seitz worked on the atomic bomb. They have been active on topics like acid rain, tobacco smoking, global warming and pesticides. The book says that these scientists have challenged and diluted the scientific consensus in the various fields, as of the dangers of smoking, the effects of acid rain, the existence of the "ozone hole", and the existence of anthropogenic climate change. Seitz and Singer have been involved with institutions such as the Heritage Foundation, the Competitive Enterprise Institute, and the George C. Marshall Institute in the United States. Funded by corporations and conservative foundations, these organizations have opposed many forms of state intervention or regulation of U.S. citizens. The book lists similar tactics in each case: "discredit the science, disseminate false information, spread confusion, and promote doubt." The book states that Seitz, Singer, Nierenberg and Robert Jastrow were all fiercely anti-communist and they viewed government regulation as a step towards socialism and communism. The authors argue that, with the collapse of the Soviet Union, they looked for another great threat to free market capitalism and found it in environmentalism. They feared that an over-reaction to environmental problems would lead to heavy-handed government intervention in the marketplace and intrusion into people's lives. Oreskes and Conway state that the longer the delay the worse these problems get, and the more likely it is that governments will need to take the draconian measures that conservatives and market fundamentalists most fear. They say that Seitz, Singer, Nierenberg and Jastrow denied the scientific evidence, contributed to a strategy of delay, and thereby helped to bring about the situation they most dreaded. The authors have a strong doubt about the ability of the media to differentiate between false truth and the actual science in question; however, they stop short of endorsing censorship in the name of science. According to the authors, the journalistic norm of balanced reporting has been undermined to amplify the misleading messages of the contrarians through false balance. Oreskes and Conway state: "small numbers of people can have large, negative impacts, especially if they are organised, determined and have access to power". The main conclusion of the book is that there would have been more progress in policy making if not for the influence of the contrarian "experts", who tried for ideological reasons to undermine trust in the science base for regulation. Similar conclusions were already drawn, among others on Frederick Seitz and William Nierenberg in the book Requiem for a Species: Why We Resist the Truth about Climate Change (2010) by Australian academic Clive Hamilton.

Worked examples

Example 1 — a first encounter with Merchants of Doubt

Start with the simplest possible case. Write down what Merchants of Doubt claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Merchants of Doubt before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Merchants of Doubt ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Merchants of Doubt

In research
Merchants of Doubt appears in earth science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Merchants of Doubt in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Merchants of Doubt is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2010 in the environment, 2010 non-fiction books, 21st-century history books, so understanding it makes those chapters shorter.
In everyday life
Look for Merchants of Doubt outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
