Top Ten Conspiracy Theories

The list of conspiracy theories is a collection of the most popular theories related but not limited to clandestine government plans, elaborate murder plots, suppression of secret technology and knowledge, and other supposed schemes behind certain political, cultural, and historical events.

While a conspiracy is defined by law as an agreement between two or more people to commit a crime, fraud, or other wrongful act, a conspiracy theory attempts to attribute the ultimate cause of an event (usually major political, social, historical, or cultural events), chain of events, or the concealment of causes from public knowledge, to a secret and often deceptive plan by a group of people or organizations. Such theories usually go against a general consensus or cannot be proven using the historical method. Here's the top ten conspiracy theories.


Purposely excluded from this list are proven historical conspiracies, e.g. the conspiracy to assassinate U.S. President Abraham Lincoln and members of his cabinet in 1865.

Conspiracy theory is a term that originally was a neutral descriptor for any claim of civil, criminal, or political conspiracy. However, it has become largely pejorative and used almost exclusively to refer to any fringe theory which explains a historical or current event as the result of a secret plot by conspirators of almost superhuman power and cunning.

Conspiracy theories are viewed with skepticism by scholars because they are rarely supported by any conclusive evidence and contrast with institutional analysis, which focuses on people's collective behavior in publicly known institutions, as recorded in scholarly material and mainstream media reports, to explain historical or current events, rather than speculate on the motives and actions of secretive coalitions of individuals. The term is therefore often used dismissively in an attempt to characterize a belief as outlandishly false and held by a person judged to be a crank or a group confined to the lunatic fringe. Such characterization is often the subject of dispute due to its possible unfairness and inaccuracy.

According to political scientist Michael Barkun, conspiracy theories once limited to fringe audiences have become commonplace in mass media. He argues that this has contributed to conspiracism emerging as a cultural phenomenon in the United States of the late 20th and early 21st centuries, and the possible replacement of democracy by conspiracy as the dominant paradigm of political action in the public mind. According to anthropologists Todd Sanders and Harry G. West, "evidence suggests that a broad cross section of Americans today…gives credence to at least some conspiracy theories." Belief in conspiracy theories has therefore become a topic of interest for sociologists, psychologists and experts in folklore.

Some deaths that are officially recorded as accident, suicide or natural causes are also the subject of some conspiracy theories. Examples include the car crash that killed Diana, Princess of Wales and Dodi Fayed in 1997, the death of John F. Kennedy Jr. in a plane crash in 1999, and the death of Senator Paul Wellstone in a plane crash in 2002. Other examples include: the suicide of Deputy White House Counsel Vincent Foster; the plane crash that killed United States Secretary of Commerce Ron Brown; the Mayerling Incident; and the deaths of U.S. Presidents Zachary Taylor and Lyndon B. Johnson, Władysław Sikorski, James Forrestal, British political leader Hugh Gaitskell, Australian prime minister Harold Holt, James P. Brady, New Zealand prime minister Norman Kirk, Jimmy Hoffa and David Kelly. There are also theories about untimely deaths of celebrities, the number one example arguably being the death of Marilyn Monroe, but also Sam Cooke, Brian Jones, Tupac Shakur, Christopher Wallace, Jimi Hendrix, Kurt Cobain, Jeff Buckley, Janis Joplin, Jim Morrison, Elvis Presley, Bob Marley, John Lennon, and more recently Michael Jackson.
