What a Conspiracy Theorist Believes

Posted by Gary Marcus, The New Yorker

On a four-point scale, from one (strongly disagree) to four (strongly agree), please rate the following statements: “The Apollo moon landings never happened and were staged in a Hollywood film studio”; ”Princess Diana’s death was not an accident but rather an organized assassination by members of the British Royal Family who disliked her”; “The Coca-Cola Company intentionally changed to an inferior formula with the intent of driving up demand for their classic product, later reintroducing it for their financial gain”; and “Carbon dioxide emissions resulting from human activities cause climate change.”

Questions like those formed the core of one of the most intriguing studies I have seen in a long time, a brand-new study, just published in Psychological Science, that investigated the dynamics of science doubters. The Australian psychologist Stephan Lewandowsky and two collaborators surveyed over a thousand visitors to online climate blogs (all relatively positive toward science), and asked them questions about free-market ideology and their views on climate science. The investigators also probed for their “conspiracist ideation” by asking questions like the ones above about faked Apollo moon landings and the assassination of Princess Diana. Some subjects were eliminated because they appear to have lied about their age (it is doubtful that anyone under five completed the survey, for instance), and as a precaution, to prevent ballot-box stuffing, the experimenters also eliminated answers where more than one response came a single I.P. address.

In principle, you could imagine that people’s answers to these questions might be logically independent. One could be a conspiracy theorist about Coca-Cola without having any particular views about climate change, or vice versa. And indeed, some subjects really did believe in climate change even as they doubted the intentions of the sugar-water company from Atlanta, and vice versa.

But, over all, the trends were clear. The more people believed in free-market ideology, the less they believed in climate science; the more they accepted science in general, the more they accepted the conclusions of climate science; and the more likely they were to be conspiracy theorists, the less likely they were to believe in climate science.

Those who are making dire predictions now would be more believable if they would at least admit past failures. Here are a few samples of the coming apocalypse as predicted on and around Earth Day, 1970:
1. "Civilization will end within 15 or 30 years unless immediate action is taken against problems facing mankind." — Harvard biologist George Wald
2. "We are in an environmental crisis which threatens the survival of this nation, and of the world as a suitable place of human habitation." — Washington University biologist Barry Commoner
3. "Man must stop pollution and conserve his resources, not merely to enhance existence but to save the race from intolerable deterioration and possible extinction." — New York Times editorial
4. "Population will inevitably and completely outstrip whatever small increases in food supplies we make. The death rate will increase until at least 100-200 million people per year will be starving to death during the next ten years." — Stanford University biologist Paul Ehrlich
5. "Most of the people who are going to die in the greatest cataclysm in the history of man have already been born… [By 1975] some experts feel that food shortages will have escalated the present level of world hunger and starvation into famines of unbelievable proportions. Other experts, more optimistic, think the ultimate food-population collision will not occur until the decade of the 1980s." — Paul Ehrlich
6. "It is already too late to avoid mass starvation," — Denis Hayes, Chief organizer for Earth Day
7. "Demographers agree almost unanimously on the following grim timetable: by 1975 widespread famines will begin in India; these will spread by 1990 to include all of India, Pakistan, China and the Near East, Africa. By the year 2000, or conceivably sooner, South and Central America will exist under famine conditions…. By the year 2000, thirty years from now, the entire world, with the exception of Western Europe, North America, and Australia, will be in famine." — North Texas State University professor Peter Gunter
8. "In a decade, urban dwellers will have to wear gas masks to survive air pollution… by 1985 air pollution will have reduced the amount of sunlight reaching earth by one half." — Life magazine
9. "At the present rate of nitrogen buildup, it's only a matter of time before light will be filtered out of the atmosphere and none of our land will be usable." — Ecologist Kenneth Watt
10. "Air pollution...is certainly going to take hundreds of thousands of lives in the next few years alone." — Paul Ehrlich
11. "By the year 2000, if present trends continue, we will be using up crude oil at such a rate… that there won't be any more crude oil. You'll drive up to the pump and say, ‘Fill 'er up, buddy,' and he'll say, ‘I am very sorry, there isn't any.'" — Ecologist Kenneth Watt
12. "[One] theory assumes that the earth's cloud cover will continue to thicken as more dust, fumes, and water vapor are belched into the atmosphere by industrial smokestacks and jet planes. Screened from the sun's heat, the planet will cool, the water vapor will fall and freeze, and a new Ice Age will be born." — Newsweek magazine
13. "The world has been chilling sharply for about twenty years. If present trends continue, the world will be about four degrees colder for the global mean temperature in 1990, but eleven degrees colder in the year 2000. This is about twice what it would take to put us into an ice age." — Kenneth Watt
