Manufacturing Doubt
Corporations have long history of perpetuating deadly products and activities by promoting "scientific uncertainty" Print-friendly Page By Daniel Engber

In 1969, a series of historic memorandums began to circulate at a tobacco company in Kentucky. The documents addressed growing public concern over the health risks associated with smoking and outlined a brazen response: The cigarette manufacturers would "establish—once and for all—that no scientific evidence has ever been produced, presented or submitted to prove conclusively that cigarette smoking causes cancer." To support this ludicrous assertion (which the tobacco executives knew to be false) would require a spin campaign of monumental proportions. That campaign's inaugural words have now become a slogan for corporate connivery: "Doubt is our product,"read one infamous memo,"since it is the best means of competing with the 'body of fact' that exists in the mind of the general public."
This corporate strategy of "manufactured uncertainty" has become only more refined in the last 40 years. According to former Assistant Secretary of Energy David Michaels, whose startling new book, Doubt Is Their Product: How Industry's Assault on Science Threatens Your Health, comes out this week, manufacturers routinely hire "product defense" firms to challenge scientific findings and stave off government regulation. Scientific consultants are brought in to dust off and reanalyze data sets, group and regroup subject pools, and dream up confounding variables—all so that a given study can be discredited as inconclusive or, worse, labeled as "junk science."
Indeed, corporations now use the manufactured-uncertainty strategy in almost every debate over environmental and public health. Energy companies wage doubt campaigns to delay action on climate change. Drug companies undercut results from clinical trials. Even the Indoor Tanning Association has lately gotten in on the action—touting the lack of "compelling evidence" that links UV exposure to melanoma. But the exploitation of uncertainty has become something larger and more significant than an industry PR tactic. It's now a political instrument, even semi-official White House policy. And ideological groups—bible-thumpers and tree-huggers alike—embrace its doubt-spewing rhetoric.
What makes this mode of thinking so effective—and so prevalent? Like David Berlinski, the doubt-mongers swear by the foundational motto of organized science, first pronounced by the Royal Society of London in 1663: Nullius in verb, "on no man's word." They show a deep commitment to the evidentiary record, always testing the established theories and demanding more data; they attempt to undermine science from within, by aping its vaunted incredulity. But in practice their contrarian mode amounts to something like the opposite of science—a tireless search for nonanswers, a quest for the null hypothesis.
Michaels gives a detailed history of how the beryllium industry, for example, has put this anti-science to work. By 1991, academic researchers had gathered enough data to conclude that the metal was a potent carcinogen and a danger to factory workers. But a team of scientists hired by the manufacturers looked at the same studies and disagreed. The cancers, they argued in their own peer-reviewed study, might have been caused by sulfuric acid mist on the factory floor, not beryllium. When no evidence materialized to support the acid-mist hypothesis, the industry team shifted tactics: Beryllium may cause cancer, they said, but what if not all forms of the metal were equally toxic? What if particles of one size were more dangerous than others? After more than 10 years of debate, the federal government once again put off tightening the standards for workplace exposure—at least until more data could be collected. ........(more)
