What is Merchants of Doubt about?

Merchants of Doubt (2011) examines some of the world’s major scientific debates on topics including the environment, smoking and nuclear weapons. These blinks will explain how a handful of extremely vocal scientists have heavily misrepresented these issues through the mainstream media, often with the goal of aiding corporate and industry interests.

Key idea 1 of 7

The tobacco industry intentionally misinformed the public about the dangers of smoking.

Nowadays, even a kid could tell you that smoking kills. But this now well-known fact was not such common knowledge in the second half of the twentieth century. It’s shocking now, but plenty of people had no idea about smoking’s adverse health effects. But did the tobacco industry itself know about its product’s dirty secret?

Absolutely.

In fact, they knew that smoking was harmful as early as the 1950s, when the tobacco industry first came under scrutiny regarding the harmful effects of cigarettes. Realizing that they had to take action, in 1953, the four biggest tobacco companies in the United States – American Tobacco, Benson and Hedges, Philip Morris and US Tobacco – joined forces in defense of their industry.

Their strategy?

To hire a PR firm, Hill and Knowlton, to save tobacco’s deteriorating image. This same decision would later be used as evidence in court to prove that the tobacco industry was well aware of its product’s harmful effects, and had thus knowingly misled their customers.

The strategy itself was simple: simply cast doubt upon the idea that smoking was bad for your health. So, as more research indicating tobacco’s harmful effects began to emerge in the 1960s and ‘70s, the tobacco companies opted for the only strategy at their disposal: challenging scientifically proven facts by propagating doubt about their validity.

For instance, in 1979, the tobacco industry began a program that funded top universities like Harvard. They committed $45 million over six years for one purpose: to prove that smoking was not connected to health problems.

But they didn’t just fund universities; they also hired a respected scientist by the name of Frederick Seitz, who distributed the money himself and gave the tobacco industry’s credibility an added boost.

They even summoned scientists to testify in court that there was no connection between smoking tobacco and poor health. However, the industry could only suppress the truth for so long, and eventually people wisened up.

The tobacco industry continued its campaign to cast doubt on the harms of secondhand smoke, as well as on science itself.

Despite their best efforts, the tobacco industry couldn’t keep its product’s harmful effects under wraps. But when scientific evidence of smoking’s health risks first came to light, it only concerned the act of smoking itself. In fact, the dangers of passive tobacco smoking weren’t proven and acknowledged until the 1980s!

In 1980 and ‘81, British and Japanese studies proved that non-smokers experienced decreased lung function after being in smoky environments. Then, in 1986, the US Surgeon General reported that second-hand smoke was as dangerous as smoking. And finally, in 1992, the US Environmental Protection Agency, or EPA, issued a report detailing second-hand smoke’s harmful effects.

The scientific debate about nuclear weapons was artificially prolonged.

Nuclear war has been a major topic of conversation since the first atomic warheads were developed and, as recently as the 1980s, the conversation about how to prevent such a catastrophe was in full, heated swing. In fact, fear of nuclear war prompted scientists to wage their own war, against a government defense protocol of the 1980s.

Here’s what happened:

The US government undermined scientific findings on acid rain in the 1970s.

The latter half of the twentieth century saw the emergence of environmental issues that demanded the attention of scientists and politicians. One such problem was acid rain. In fact, the phenomenon has been studied in detail since the 1960s, and plenty of scientific evidence has been compiled on its origins and effects.

Acid rain is essentially rain with a lower than normal pH concentration. It leads to a variety of problems such as decreased forest and plant growth, and it can kill animals such as fish. Over time, scientists began to trace acid rain to the burning of fossil fuels and determined that the pollution that causes it often occurs in a different geographical area than where the rain itself falls.

The hole in the ozone layer was debated into the 1990s.

It’s common for science to advance slowly, especially when industry interests are at stake, and this was especially true throughout the scientific discussions regarding the depletion of the ozone layer. It should thus come as no surprise that the conversation about whether there is in fact a hole in the ozone layer dates back almost 50 years.

In the 1970s, scientists presented indisputable evidence that certain chemicals were causing the depletion of the ozone layer. Researchers had been investigating the effects of various chemicals on the ozone layer as early as the late-1960s, and in 1970, scientist James Lovelock shared his work: he hypothesized that certain chemicals, called chlorofluorocarbons, or CFCs, which were commonly used in aerosol products like hair spray, were in fact concentrating in the Earth’s stratosphere, potentially depleting the planet’s ozone.

The science proving global warming faced an uphill battle for recognition during the 1980s.

It’s clear that there have been alarming cases in which the public was misled about dire environmental issues, and another excellent example is global warming. Despite clear scientific proof, global warming wasn’t taken seriously until the 1980s.

Why?

In the early 2000s, a long-dormant pesticide debate was resurrected as a posterchild attack on environmental regulations.

Now that you know how science can be appropriated for political ends and lobbying, it’s time for one last example: the pesticide dichlordiphenyltrichlorethan, or DDT. DDT was banned in 1972 because of its devastating environmental effects, which were first made public in the 1960s.
