#1 Government Surveillance

Edward Snowden’s revelations about the National Security Agency (NSA) collecting vast amounts of phone and internet data shattered our sense of privacy. The constant stream of news about data breaches and social media manipulation adds fuel to the fire. With technology constantly evolving and governments often tight-lipped about their capabilities, it’s not a huge leap for some to believe in even more pervasive, secret surveillance programs.

#2 Classified Documents

Governments around the world hold countless classified documents, some dating back centuries. These documents could contain evidence of past misdeeds, embarrassing truths, or even groundbreaking discoveries. The secrecy surrounding them makes people wonder what’s being hidden. What if history wasn’t what we learned in school? The potential for a dramatically different past, coupled with the slow pace of declassification, keeps this conspiracy theory alive.

#3 Government Mind Control

MKUltra, the CIA’s real-life program that experimented with mind-altering drugs in the 1950s and 60s, shows governments have considered mind control a possibility. The ethical implications are chilling. The availability of powerful psychotropic drugs and the constant development of new technologies make the idea that some government agency might be experimenting with mind control a believable conspiracy theory for some, even if the evidence for its widespread use is lacking.

#4 Area 51

Area 51, a highly classified U.S. Air Force facility, has been the center of conspiracy theories for decades. The secrecy surrounding the base fuels speculation about government research on alien technology or even captive extraterrestrials. Public curiosity about government secrecy and the allure of alien life make Area 51 a persistent conspiracy theory.

#5 Suppressed Inventions

The idea that groundbreaking inventions that could change the world are being suppressed by powerful entities for various reasons, like protecting existing industries or maintaining control over resources, is a persistent conspiracy theory. The electric car industry is often cited as an example of being a victim of sabotage, before Tesla came along. The existence of patents for seemingly unbelievable technologies adds to the intrigue. However, economic feasibility, safety concerns, and technical limitations often play a larger role than shadowy cabals in why certain inventions aren’t widely adopted.

#6 Fake Moon Landing

The conspiracy theory that the 1969 moon landing was a hoax persists. People who believe in the faked moon landing theory often cite various pieces of supposed evidence, such as inconsistencies in photographs and videos from the Apollo missions, anomalies in shadows and lighting, the lack of visible stars in the lunar sky, discrepancies in the behavior of the American flag planted on the moon’s surface, and alleged technological limitations of the time.

#7 JFK Assassination

The assassination of President John F. Kennedy in 1963 remains a touchstone for conspiracy theories. The official conclusion – that Lee Harvey Oswald acted alone – left many unsatisfied, particularly given the chaotic sequence of events and unanswered questions. Alleged ballistics inconsistencies, witness testimonies, and the suspicious death of Oswald himself fuel theories of CIA involvement, mafia plots, or a larger government cover-up.

#8 Roswell Incident

In 1947, the U.S. military’s recovery of debris near Roswell, New Mexico, sparked a firestorm of speculation. The initial claim of a weather balloon crashed against subsequent suggestions of a recovered alien spacecraft fueled a conspiracy theory that persists to this day. Government secrecy surrounding the incident only intensifies suspicion among believers who imagine a Roswell crash cover-up hiding evidence of extraterrestrial technology or even extraterrestrial beings themselves.

#9 9/11 Inside Job

The horrific terrorist attacks of September 11th, 2001 became the target of conspiracy theories questioning the official narrative. Claims of controlled demolition of the World Trade Center towers, implications of impossible plane maneuvers, and the use of crisis actors fuel speculation about prior knowledge by the U.S. government or even their direct involvement in the attacks.

#10 Planned Obsolescence

This theory alleges that companies deliberately design products with a shorter lifespan so consumers will need to replace them more frequently, boosting profits. The prevalence of products that seem to break down just after the warranty expires fuels suspicion.

#11 Artificial Food Shortages

The theory proposes that corporations or governments artificially create food shortages to drive up prices. This conspiracy theory plays on fears of food insecurity. One example often mentioned in discussions of manipulated agricultural markets is corn. Corn is a staple crop used in various food products, animal feed, and even biofuels. Critics of market manipulation theories argue that large agribusiness companies withhold surplus corn supplies or manipulate futures markets to artificially inflate prices.

#12 Big Pharma Conspiracy

The theory suggesting that pharmaceutical companies suppress cures for diseases to prioritize profits over public health often gains traction due to the exorbitant costs of prescription drugs and the financial incentives within the industry. Advocates of this theory argue that by withholding cures in favor of ongoing treatments, pharmaceutical companies can maintain lucrative revenue streams.

One concrete example often cited in discussions of inaccessible lifesaving drugs is insulin, essential for managing diabetes. The cost of insulin has skyrocketed in recent years, making it unaffordable for many patients, leading to public outcry and accusations of price gouging by pharmaceutical companies. This example fuels suspicions that profit motives sometimes take precedence over ensuring affordable access to vital medications.

#13 Subliminal Messaging

The idea that advertisers or media producers embed hidden messages in commercials, music, or movies to influence our behavior has been a conspiracy theory for decades. While studies haven’t shown subliminal messages to be powerful persuaders, the psychological concept of priming suggests subtle cues can influence our thoughts and actions. This keeps the subliminal messaging conspiracy theory alive.

#14 False Flags

This theory proposes that governments stage terrorist attacks or other disasters to manipulate public opinion and justify war or increased surveillance. In American history, the theory of false flag operations often refers to the events surrounding the Gulf of Tonkin incident during the Vietnam War era. In 1964, reports claimed that North Vietnamese torpedo boats had attacked American destroyers in the Gulf of Tonkin. This incident served as a catalyst for the escalation of U.S. military involvement in Vietnam, with Congress passing the Gulf of Tonkin Resolution, effectively granting President Lyndon B. Johnson broad authority to use military force in Southeast Asia.

However, subsequent investigations and declassified documents revealed discrepancies and uncertainties about the actual events of the Gulf of Tonkin incident, leading to suspicions that the incident may have been manipulated or exaggerated to justify increased American military action in Vietnam. The complexity of intelligence operations and the fog of war contribute to ongoing speculation and skepticism surrounding such historical events.

#15 New World Order

This theory posits a secret global cabal of powerful individuals or organizations working towards a unified world government. The theory often includes elements of economic domination and suppression of individual liberty. The interconnectedness of the modern world and the influence of multinational corporations can make the idea of a New World Order seem plausible to some.

#16 Hidden History

This theory suggests there are lost civilizations or advanced ancient cultures whose achievements have been covered up by powerful institutions.

One example often brought up in discussions of hidden or suppressed ancient civilizations is the theory surrounding the ancient city of Göbekli Tepe in modern-day Turkey. Dating back over 11,000 years, Göbekli Tepe is an archaeological site featuring intricately carved megalithic structures, believed to be one of the oldest known religious sites in the world. Proponents of the theory suggest that the discovery challenges existing theories about the development of human civilization, potentially indicating the existence of advanced cultures much earlier than previously thought. However, some conspiracy theorists propose that governments or powerful institutions may suppress or downplay findings that contradict established historical narratives, in order to maintain control over mainstream historical discourse. The mystery surrounding Göbekli Tepe and its implications for understanding human history continue to fuel speculation about potential cover-ups by authorities.

#17 Denial of Bigfoot

This conspiracy theory suggests evidence of Bigfoot, a large hairy hominid allegedly living in remote forests, is being suppressed by authorities to protect tourism industries or for other reasons. Grainy footage and plaster casts of supposed Bigfoot tracks fuel the theory. The romantic notion of unidentified creatures and the luscious imagery of unexplored wilderness make Bigfoot denial a conspiracy theory with lasting appeal, despite the lack of concrete proof.

#18 Fake News & Media Bias

This theory suggests that mainstream media outlets deliberately distort information to manipulate public opinion and advance a particular agenda. The spread of misinformation on social media and the partisan divide in news coverage contribute to a climate of distrust. However, it’s important to distinguish between accidental errors or bias in reporting and a concerted effort to fabricate news.

#19 Celebrity Clones

This theory proposes that some celebrities have been secretly replaced with clones to explain changes in appearance or avoid death. A concrete example often cited in discussions of celebrity clone conspiracy theories involves the singer Avril Lavigne. According to the theory, some fans speculate that Avril Lavigne was replaced by a look-alike named Melissa Vandella after her alleged death in the early 2000s. Proponents of this theory point to perceived changes in her appearance and behavior over the years as evidence of the switch. The intense scrutiny celebrities face, combined with the prevalence of cosmetic procedures and plastic surgery in the entertainment industry, adds to the intrigue and plausibility of such conspiracy theories among certain fans and followers.

#20 Genetically Modified Organisms (GMOs)

This theory raises concerns about the safety and ethics of genetically modified foods. Some believe GMOs can harm human health or the environment, or that corporations are manipulating the food supply for profit. The lack of transparency in corporate practices and the complexities of genetic engineering fuel public anxieties.

#21 Near-Death Experiences (NDEs)

NDEs, where people report vivid experiences during clinical death, spark the conspiracy theory that they offer proof of an afterlife or another dimension. While NDEs can be profound and life-changing, scientific explanations often focus on altered brain function during periods of oxygen deprivation. The mystery of consciousness and the desire for an existence beyond physical death fuel the conspiracy theory, but the interpretation of NDEs remains a complex issue.
