Conspiracy Theories
A conspiracy theory explains events by invoking a secret plot by a group of conspirators
Conspiracy Theories vs Straightforward Explanations
- A conspiracy theory explains the evidence as resulting from a secret plot by a powerful group of conspirators.
- But there’s always a simpler, straightforward explanation of the evidence.

For Example

Unsupported Non-conspiracy Theories
- Not all unsupported theories postulate a conspiracy.
- Vaccines cause autism
- Astrology

QAnon
- FBI Intelligence Bulletin, May 30, 2019
- The FBI assesses in some cases anti-government, identity based, and fringe political conspiracy theories very likely encourage the targeting of specific people, places, and organizations, thereby increasing the risk of extremist violence against such targets.
- Fringe Political:
- QAnon: An anonymous government official known as “Q” posts classified information online to reveal a covert effort, led by President Trump, to dismantle a conspiracy involving “deep state” actors and global elites allegedly engaged in an international child sex trafficking ring.’
- The Prophecies of QAtlantic
- On October 28, 2017, the anonymous user now widely referred to as “Q” appeared for the first time on 4chan, a so-called image board known for its grotesque memes, sickening photographs, and brutal teardown culture. Q predicted the imminent arrest of Hillary Clinton and a violent uprising nationwide, posting this:
- “HRC extradition already in motion effective yesterday with several countries in case of cross border run. Passport approved to be flagged effective 10/30 @ 12:01am. Expect massive riots organized in defiance and others fleeing the US to occur. US M’s will conduct the operation while NG activated. Proof check: Locate a NG member and ask if activated for duty 10/30 across most major cities.”

Evaluating Conspiracy Theories
- A conspiracy theory is implausible to the extent the competing straightforward theory is reasonable.
- Since conspiracy theories are more complicated than straightforward explanations, an a priori reason for doubting them is the Principle of Simplicity, or Ockham’s Razor:
- The simpler of competing theories is more likely, other things being equal.
- The “evidence” for a conspiracy theory is sometimes bogus.
- Fact-checkers provide useful analysis:
- Gingrich Spreads Conspiracy Theory
- Trump’s ‘evidence’ for Obama wiretap claims relies on sketchy, anonymously sourced reports
- Conspiracy theorists peddle fake claim about the 1986 Challenger Space Shuttle disaster
- Conspiracy theorists sometimes claim they have evidence that can’t be produced because, they say, the evidence is based on anonymous FBI sources or the conspirators destroyed it all. Either way, no evidence is forthcoming.
Why People Believe
- scientificamerican.com/article/why-do-people-believe-in-conspiracy-theories/
- Surveys by Uscinski and Parent show that believers in conspiracies “cut across gender, age, race, income, political affiliation, educational level, and occupational status.”
- wikipedia.org/wiki/Conspiracy_theory
- According to the political scientist Michael Barkun, conspiracy theories rely on the view that the universe is governed by design, and embody three principles:
- nothing happens by accident
- nothing is as it seems
- everything is connected.
- Another common feature is that conspiracy theories evolve to incorporate whatever evidence exists against them, so that they become, as Barkun writes, a closed system that is unfalsifiable, and therefore “a matter of faith rather than proof”

- “The best predictor of belief in a conspiracy theory is belief in other conspiracy theories,” says Viren Swami, a psychology professor who studies conspiracy belief at the University of Westminster in England. Psychologists say that’s because a conspiracy theory isn’t so much a response to a single event as it is an expression of an overarching worldview.
- “If you know the truth and others don’t, that’s one way you can reassert feelings of having agency,” Swami says. It can be comforting to do your own research even if that research is flawed. It feels good to be the wise old goat in a flock of sheep.
