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.

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 Q The Atlantic
- 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.”

Trump’s Conspiracy Theories
- Inside Trump’s Truth Social Conspiracy Theory Machine NY Times
- The Times analyzed thousands of Mr. Trump’s posts and reposts over a six-month period in 2024 and found that at least 330 of them met two tightly defined and striking criteria: They each described both a false, secretive plot against Mr. Trump or the American people and a specific entity supposedly responsible for it. The unfounded theories ranged from suggestions that the F.B.I. had ordered his assassination to accusations that government officials had orchestrated the Capitol riot on Jan. 6, 2021.
- The Times’s analysis identified 10 distinct themes in the conspiracy theories shared by Mr. Trump:
- 268 posts about 2024 election interference

- Includes claims that Mr. Trump’s adversaries are puppets of the philanthropist George Soros and other “globalist” actors.

- “Here, we summarize some of the conspiracy theories that Trump has either explicitly pushed or subtly elevated both before and during his time in the White House — many of which we’ve covered at length before.”
- Sam Stein, The Bulwark 9/16/2024
- The former president has been a prolific conspiracy theorist for decades.
- Trump was the de facto leader of the Obama birther movement, even casually suggesting that the director of the Hawaii Department of Health, who died in a plane crash, was murdered as part of a coverup.
- He openly mused that former Weather Underground member Bill Ayers wrote Obama’s memoir and that Obama never actually went to Columbia University.
- He floated the idea that Ted Cruz’s father had ties to Lee Harvey Oswald. He raised doubts about Vince Foster’s suicide.
- He wondered aloud if Supreme Court Justice Antonin Scalia was suffocated to death.
- He pushed the story that Muslims in New Jersey were cheering after 9/11.
- He raised the idea that Marco Rubio was ineligible to be president because his parents weren’t yet U.S. citizens at the time of his birth. He did the same about Ted Cruz. And Nikki Haley. And Kamala Harris, too.
- He questioned the authenticity of the Access Hollywood tape (this was after he apologized for it).
- He claimed Obama had him wiretapped at Trump Tower.
- He claimed the death toll from Hurricane Maria was inflated to make him look bad.
- He said the noise from windmills causes cancer.
- He pushed a video saying that the Clintons killed Jeffrey Epstein.
- He said Ukraine could be hiding Hillary Clinton’s missing emails.
- He said that “the concept of global warming was created by and for the Chinese in order to make U.S. manufacturing non-competitive.”
- He said that fears about asbestos were a conspiracy designed to line the pockets of asbestos-cleanup companies run by the mob.
- He retweeted several conspiracy theories around the death of Osama bin Laden (that it could have been a body double).
- He has said jobs numbers are manipulated, the unemployment figure was made up, the COVID death numbers were inflated, the Obamacare enrollment numbers were exaggerated, and the border crossing numbers “manipulated” to make the Obama administration look better.
- And, of course, he’s spread a steady stream of lies about election numbers.
- The 2012 one: dead people voted for Obama.
- The 2016 one: cheating in blue states like California and New York deprived him of a popular vote win.
- The 2020 one . . . where do we even start?
- Sharpies did not invalidate Trump votes;
- Dominion did not either.
- People weren’t throwing away bags filled with Trump ballots or randomly finding suitcases filled with Biden ones.
- Thousands of dead people didn’t vote multiple times.
- And, no, Italians did not use military technology to tamper with U.S. voting machines.
- The former president has been a prolific conspiracy theorist for decades.

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
- Some conspiracy theorists claim they have evidence which they promise to produce later, but never do. Other conspiracy theorists claim they can’t produce evidence because the it’s based on anonymous FBI sources or the conspirators destroyed it all. No matter the reason, 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”
- According to the political scientist Michael Barkun, conspiracy theories rely on the view that the universe is governed by design, and embody three principles:
- Why Rational People Buy Into Conspiracy Theories, New York Times Magazine, Maggie Koerth-Baker
- “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.
