The secret origins of 'conspiracy theory'

In an era where skepticism is often dismissed as pathology, this piece offers a startling correction: the very phrase we use to stigmatize dissent was once a neutral tool of forensic investigation. Reason reports that the term "conspiracy theory" did not begin as an insult but as a legal description for cases involving multiple perpetrators, only later mutating into a weapon to silence political inquiry.

The Linguistic Shift

The article argues that our current understanding is a historical accident rather than an inevitable evolution of language. "In the 19th century," Reason notes, "the words 'conspiracy theory' were typically deployed in a forensic context." It was a straightforward description: if a detective suspected more than one person committed a crime, they proposed a conspiracy theory. The piece highlights how this neutrality persisted even into major political tragedies, citing the St. Louis Daily Globe-Democrat using the term to discuss speculations around President James Garfield's assassination without any pejorative intent.

The secret origins of 'conspiracy theory'

This reframing is crucial because it exposes how language can be weaponized over time. The article traces how mid-20th-century thinkers like Karl Popper and Franz Neumann expanded the phrase into a "conspiracy theory of society," yet even then, it lacked the modern sting. It was only when the phrase was shortened to stand alone as a genre—"conspiracy theories"—that it became a label for a type of person rather than a description of an event.

The phrase 'conspiracy theory,' in the sense that people use it today, became popular in the wake of commentaries like Popper's and Neumann's.

Critics might argue that focusing on etymology distracts from the very real danger of baseless claims undermining democratic institutions. However, the piece suggests that by pathologizing all suspicion, we risk ignoring actual corruption.

From Detective to Prophet

The commentary delves into how the term split into two distinct modes: the "analytic" (a detective working a case) and the "apocalyptic" (a prophet revealing a cosmic struggle). Reason observes that these modes often bleed into one another, creating a space where genuine questions about events like the murder of Malcolm X can spiral into searches for a hidden hand pulling all strings.

The piece dismantles the popular myth that the Central Intelligence Agency invented the term to discredit dissidents. Instead, it traces a gradual cultural drift where "people dropped the last two words of 'conspiracy theory of history' or 'conspiracy theory of society.'" This shift allowed for the creation of the "conspiracy theorist" archetype—a figure ranging from the basement-dwelling nerd to the militia terrorist.

A conspiracy theory can spark a real conspiracy: convinced that the secret society was still active, Grolman decided to form a secret 'counter-association' against that 'devilish union.'

This reciprocal relationship is the article's most provocative insight. It suggests that the fear of conspiracies can actually manufacture them, as seen in the 1790s when Ludwig Adolf Christian von Grolman formed a real counter-society because he believed the Illuminati were still active. This mirrors historical dynamics where paranoia fuels action, much like how the Cambridge Five espionage ring operated within the very institutions designed to expose such threats.

The Irony of Intelligence

The piece concludes with intellectual biographies that reveal the stunning irony of those who studied conspiracy theories. Franz Neumann, a legal scholar who critiqued the "conspiracy theory of history," was himself revealed by post-Cold War archives to have spied for Moscow during World War II. While not on the scale of the Cambridge Five, his espionage confirms that sometimes the accusations are true.

Reason notes that McCarthy's sloppy charges against Neumann turned out to be correct in this specific instance: "the conspiracy theory turned out to be correct." This complicates the narrative that all conspiracy theorists are merely paranoid fringe elements. The article also examines Richard Hofstadter, whose famous essay on the "paranoid style" is respected but critiqued for suggesting conspiracism is limited to a "modest minority," a claim later scholars like David Brion Davis refuted by showing how widespread such anxieties were during the Civil War era.

There is no way, reading a book like The Slave Power Conspiracy, that you could ever mistake its subjects for an easily pathologized movement of a social fringe.

Finally, the piece explores Carl Oglesby, a New Left leader who viewed the JFK assassination and Watergate as battles between rival factions of the ruling class. The commentary notes Oglesby's unique position: "He was more Sherlock Holmes than Marx." This distinction matters because it frames the conspiracy theorist not as a lunatic, but as an investigator trying to solve a puzzle that official narratives refuse to acknowledge.

Bottom Line

The strongest part of this argument is its demonstration that skepticism is often a rational response to opaque power structures, not just a symptom of mental instability. Its biggest vulnerability lies in the difficulty of distinguishing between legitimate investigative journalism and genuine disinformation without falling back on the very stigmatizing labels the article critiques. Readers should watch for how institutions continue to use linguistic shifts to delegitimize scrutiny rather than addressing the underlying grievances that fuel it.

The Hidden History of Conspiracy Theory, by Andrew McKenzie-McHarg, Princeton University Press, 674 pages, $42.95

"Homer conceived the power of the gods in such a way that whatever happened on the plain before Troy was only a reflection of the various conspiracies on Olympus," Karl Popper told an Oxford lecture hall in 1948. "The conspiracy theory of society," the philosopher added, simply replaces those deities with "sinister pressure groups."

That passage, which Popper then revised and incorporated into the second edition of The Open Society and Its Enemies, is sometimes cited as the moment the expression "conspiracy theories" entered the language. But in The Hidden History of Conspiracy Theory, the most original study of the subject to come along in years, the Australian historian Andrew McKenzie-McHarg argues that this is both too late and too early for that honor—too late because the phrase is actually much older than that, too early because Popper's term was subtly different from the one people usually use today.

In the 19th century, McKenzie-McHarg shows, the words "conspiracy theory" were typically deployed in a forensic context. In the aftermath of a crime, a detective or lawyer or reporter might speak in entirely neutral terms about a conspiracy theory of what happened, meaning that more than one perp might have been involved. When the phrase came up in a political context, it was still being used that way: After President James Garfield was shot, the St. Louis Daily Globe-Democrat used the term while editorializing about the speculations around the assassination. The plural form, "conspiracy theories," was vanishingly rare.

Writers sometimes referred to the conspiracy theory of something: the conspiracy theory of a murder, for example. So when Popper spoke about the more cosmic "conspiracy theory of society"—or when the legal scholar Franz Neumann critiqued the "conspiracy theory of history," or others in the mid-20th century spoke about the "conspiracy theory of government" or "conspiracy theory of politics"—they were just extending that linguistic formula.

Even before then, the phrase "conspiracy" was sometimes used to stigmatize ideas. (In 1935, a former congressman mocked the "conspiracy complex" of people who blame world events on hidden forces.) But the phrase "conspiracy theory" did not, by itself, carry a stigma. Neumann himself was involved with the Nuremberg prosecutions of Nazi war criminals, where jurists used the term in an entirely non-pejorative manner: They were discussing whether to charge the defendants with
