Let’s stop talking about conspiracy “theories”

A few years ago, I taught an undergraduate course on “Cons, Cults, and Conspiracy Theories,” exploring the connections and parallels among those phenomena. Many of my students had some experience with cons, often from work in the service industry. Several also had relatives who had been in cults of various ilks. However, students were overwhelmingly skeptical of conspiracies theories. As we explored the three c’s, I found myself struggling with the term “conspiracy theory.” The term “theory” lends a patina a of scientific thought and rigor that is often lacking in fabulist conspiracy narratives. 

The term “conspiracy theory” has a long history. It is sometimes erroneously attributed to the US Central Intelligence Agency, but, according to Andrew McKenzie-McHarg, the term can be found in nineteenth-century press accounts of trials and in the coverage of the assassination of US President James Garfield.  

In academic use, the term “conspiracy theory of society” was popularized by Karl Popper in a pair of papers delivered in 1948, and later in the second edition of his book The Open Society in 1952. Popper described it as

the view that an explanation of a social phenomenon consists in the discovery of the men or groups who are interested in the occurrence of this phenomenon (sometimes it is a hidden interest which has first to be revealed) and who have planned and conspired to bring it about

—Popper, The Open Society, 1952, 94

Popper’s discussions sparked spirited commentary among other philosophers, part of which hinged on the distinction between a particular account of something as due to a conspiracy (the 1969 moon landing, the Kennedy assassination, the September 11th attacks, the COVID pandemic, etc.) and the more general tendency of looking for cabals of hidden conspirators behind all sorts of historical events.

As my students and I talked though the distinction and poked at it in various ways, we started to use the term conspiracism to refer to the tendency to believe in conspiracy theories. Some studies, such as those of Stephen Lewandowsky and colleagues, refer to this as “conspiracy ideation,” and scholars have studied the attitudes and mindset that go along with it. I found myself preferring “conspiracism” to “conspiracy ideation” because it is more concise and is parallel with other -isms—and because it suggests the self-deluding aspect of many believers in conspiracy theories. “Ideation,” like “theory,” feels academic and reasoned.

In addition, the term “conspiracy theory” itself is problematic in other ways, as scholars such as Jesse Walker (and my undergraduates) have noted. The term is loaded with negative connotations as well as positive ones. Today, “conspiracy theory” and “conspiracy theorist” suggest tinfoil-hat beliefs in the wildest counter-factual narratives and the fuzziest thinking. And to make matters even more complicated, there are actual conspiracies in the world—political, criminal, business—and before they are confirmed as actual conspiracies, there might be “theories” about what happened. Once the conspiracy is confirmed, we tend not to refer to it with the word “theory.” No one talks about the conspiracy theory of Watergate, for example. Rhetorically, there are conspiracies, theories about conspiracies (which are subject to evidence constraints), and “conspiracy theories” (which are not if you are a conspiracist).

A friend of mine once suggested that such unfalsifiable “conspiracy theories” be treated as fan-fiction about history and current event. That’s a bit unwieldy and does a disservice to fan-fiction, I think. But the notion underscores the way in which conspiracy theories typically have key fabulists and promoters and a dedicated fan base of believers. Maybe we should start referring to them as “conspiracy fiction.”

As a linguist, I know that I can’t control usage other than by example, but I’m going to start referring to “conspiracy fiction” and “conspiracism.” Maybe the terms will catch on.
