Merchants of Doubt (film)

The filmmakers interviewed more than a dozen individuals who have been involved in a series of conflicts ranging from the regulation of tobacco products due to the health risks to global climate change. In the sequence in which they appear in the film, they are:

• Stanton Glantz is a professor of medicine and activist for regulation of tobacco smoking. In 1994 he received a carton of documents copied from the records of the Brown and Williamson tobacco company that revealed their awareness of health risks as early as the 1950s.
• Sam Roe and Patricia Callahan are reporters at the Chicago Tribune newspaper who in 2012 exposed "manufacturers that imperil public health by continuing to use toxic fire retardants in household furniture and crib mattresses, triggering reform efforts at the state and national level." They were finalists for a Pulitzer Prize for Investigative Reporting.[6]
• James Hansen is a former NASA scientist whose 1988 testimony on climate change to congressional committees helped raise broad awareness of global warming, and has become a prominent advocate for regulation of greenhouse gas emissions.
• John Passacantando is the former executive director of Greenpeace, an organization of environmental activists.
• William O'Keefe is the chief executive officer of the George C. Marshall Institute,[7] an organization that opposes government regulation of greenhouse gas emissions.

Fred Singer (2011), a prominent opponent of greenhouse gas regulation

• Naomi Oreskes is a professor of the history of science and the co-author of the book that inspired the film.
• Fred Singer is a physicist and environmental scientist who founded the Science & Environmental Policy Project (SEPP) in 1990 to work against regulation of greenhouse gas emissions, among other issues.
• Michael Shermer is a writer and publisher of the magazine Skeptic. He was initially a "contrarian" regarding regulation of greenhouse gas emissions, but his views changed as the science of climate change advanced.
• Matthew Crawford is a writer. He is a former director of the Marshall Institute who resigned over the influence of the Institute's sponsors in determining the Institute's activities and positions.
• Marc Morano is a political activist who has published the climate denial website ClimateDepot since 2009. To encourage complaints to scientists whose work is viewed as supporting action on greenhouse gas emission, the website publishes their addresses.
• Ben Santer, Michael E. Mann, and Katharine Hayhoe are climate scientists who have received personal threats because of their global climate change work.
• Tim Phillips is the president of Americans for Prosperity, which works against government regulation on climate change and other issues.
• Bob Inglis is a former congressional representative from South Carolina; he lost his seat in the primary election following his announcement that he had changed his view and recognized global climate change as a problem that government should address.

The film embeds commentary and performances by magician Jamy Ian Swiss. The premise of these interludes is that there is an analogy between the techniques of professional magicians and the tactics of public relation organizations. Magicians learn how to distract their audiences from noticing the deceptions that underlie their tricks and illusions. The organizations distract the public from the risks associated with products. These tactics were systematically developed by the tobacco industry in the 1950s in response to scientific research showing that smoking was a significant health risk; the research was a significant threat to tobacco sales. The principal distraction tactic has been the use of convincing personalities who claim that the uncertainties in the risks militate against taking action.

An unsigned review in The Boston Globe explains, "To make his point clear, Kenner follows up Swiss’s magic act and fancy patter with a snappy montage of various experts over the years denying that cigarettes cause cancer, or extolling the virtues of pesticide, or proclaiming that asbestos is “designed to last a lifetime — a trouble free lifetime.” And then the inevitable parade of climate change deniers bloviating in Congress or on cable news, all backed by Sinatra singing “That Old Black Magic.”"[8] A. O. Scott wrote in The New York Times that Swiss' "presence, and the animated playing cards that sometimes fly across the screen, feel like a glib and somewhat condescending gimmick, an attempt to wring some fun out of a grim and appalling story."[9]

One of the subjects of the film, Fred Singer, wrote the director indicating that he was considering a lawsuit.[10] Although no lawsuit was filed, Kenner noted in an interview that "when [Singer] implies litigation is very expensive, I think it's an attempt to be intimidating." In the 1990s, Singer had sued Justin Lancaster over his statements regarding the inclusion of Roger Revelle as a co-author of a climate change paper with Singer and Chauncey Starr; Revelle had died shortly after the paper was published. That lawsuit ended when Lancaster withdrew his statements as "unwarranted", although Lancaster later expressed regret over the settlement.[11]

The film has been widely reviewed in the mainstream U.S. media and garnered mostly positive reviews. On review aggregator Rotten Tomatoes, the film holds an approval rating of 84% based on 89 reviews, with an average rating of 6.95/10. The website's critics consensus reads: "Merchants of Doubt is a thought-provoking documentary assembled with energy and style, even if it doesn't dig as deep as it could."[12] On Metacritic, the film has a weighted average score of 70 out of 100, based on 24 critics, indicating "generally favorable reviews".[13]

Justin Chang wrote for Variety that it is "An intelligent, solidly argued and almost too-polished takedown of America’s spin factory — that network of professional fabricators, obfuscators and pseudo-scientists who have lately attempted to muddle the scientific debate around global warming — this is a movie so intrigued by its designated villains that it almost conveys a perverse form of admiration, and the fascination proves contagious."[14] William Goss wrote for The Austin Chronicle that "Merchants spends much of its running time exposing trends of political subterfuge before working in an earnest call to action regarding climate change. Using the same type of tinkling score and shots of children at play as campaign ads shown earlier in the film, this late-inning agenda comes off as noble as it is hypocritical. Regardless of one’s personal beliefs, it’s tough to respect a movie that ultimately invites viewers to question every case of propaganda except its own."[15]
