Teamsters president Jimmy Hoffa vanished on 30 July 1975 from the Machus Red Fox restaurant parking lot in Bloomfield Township, Michigan. He had arranged to meet Anthony Provenzano and Anthony Giacalone, both Mafia figures with grievances against him. The FBI declared him legally dead in 1982. Despite multiple confessions, tips, and excavations over five decades, no remains have ever been found. The broad outlines of Mob involvement are supported by testimony and circumstantial evidence; the precise disposal method remains unresolved.

Grigori Rasputin was killed at the Yusupov Palace in Petrograd on the night of 29–30 December 1916. Felix Yusupov, Grand Duke Dmitri Pavlovich, and Vladimir Purishkevich all confessed involvement. The standard account holds that Rasputin was poisoned, shot multiple times, and drowned in the Neva River. Andrew Cook's 2005 BBC-commissioned research introduced the claim that SIS officer Oswald Rayner was present and fired the final — coup de grâce — shot to the forehead, acting on British intelligence concerns that Rasputin would push Russia toward a separate peace with Germany. Some forensic and archival evidence supports British presence; the specific "Rayner fired the kill shot" claim remains unproven but is not implausible.

On the night of February 27, 1933, the German parliament building burned. Dutch communist Marinus van der Lubbe was arrested at the scene, convicted, and executed. Hitler's government used the fire within twenty-four hours to push through the Reichstag Fire Decree, suspending civil liberties and enabling mass arrests of Communist Party members. Historians have debated for ninety years whether van der Lubbe acted alone or whether the Nazis orchestrated or facilitated the fire. The majority modern view — supported by Fritz Tobias (1962), revived by Benjamin Carter Hett (2014), and confirmed by a 2008 German Federal Court reversal of van der Lubbe's conviction — is that the evidence for Nazi orchestration remains contested but the exploitation of the fire by Hitler is thoroughly documented.

Between 28 January and 4 February 2023, a Chinese high-altitude balloon transited the continental United States from Alaska to the Atlantic coast, where it was shot down by a US F-22 fighter jet off the coast of South Carolina on 4 February. China's public position was that it was a civilian meteorological balloon that had strayed off course. The Pentagon's initial public framing described it as a surveillance balloon. Subsequent Defense Department analysis, Navy recovery of debris from the seafloor, and congressional briefings confirmed the balloon carried surveillance and intelligence-collection equipment inconsistent with civilian weather use. The "civilian weather balloon" framing is debunked by the recovered hardware. The scope of any intelligence actually collected, and the degree of intentionality in the overflight, remain subjects of classified analysis and contested public characterisation.

Claims that NFL referees systematically favour specific teams — particularly the New England Patriots and Dallas Cowboys — or that the league directs officiating to produce desired outcomes circulate widely in sports media. The documented reality is more nuanced: officiating inconsistencies are real and historically significant (the catch rule pre-2018 reform, the 2018 NFC Championship missed pass-interference call, the pass-interference reviewable era 2019). Statistical analyses confirm a small but real home-team officiating advantage consistent with crowd noise affecting referee judgment. The leap from documented inconsistency to coordinated league-directed favoritism toward specific franchises is not supported by the evidence.

Michael Jackson died on June 25, 2009, from acute propofol and benzodiazepine intoxication. His personal physician Dr. Conrad Murray was convicted of involuntary manslaughter in November 2011 and sentenced to four years in prison. The established facts of Murray's criminal conviction represent real wrongdoing. Two conspiracy framings extend beyond the established facts: that AEG Live (the concert promoter) bore deliberate corporate responsibility for Murray's actions and effectively caused Jackson's death; and that Jackson faked his death and remains alive. The first framing was litigated in civil court (Katherine Jackson v. AEG Live, 2013) and the jury found in AEG's favour. The second is a documented false claim refuted by the Los Angeles County coroner's findings, death certificate, and autopsy.

Fifteen of the nineteen 9/11 hijackers were Saudi nationals. The theory that the Saudi government — as an institution — directed or materially supported the attacks has circulated since 2001 and gained traction when the "28 pages" of the Joint Congressional Inquiry were declassified in July 2016. Those pages documented contacts between several hijackers and individuals with connections to the Saudi government, including Saudi consulate and embassy staff. FBI declassifications under a 2021 Biden executive order (Operation Encore documents) provided additional detail on specific Saudi government-affiliated individuals who assisted hijackers in the Los Angeles area. The 9/11 Commission (2004) found no evidence that the Saudi government as an institution, or senior Saudi officials acting in their official capacity, funded or directed al-Qaeda's attack. The distinction between "Saudi government-affiliated individuals provided support" (substantially documented) and "Saudi government as state actor directed the attack" (not established) is central to a fair assessment.

Lee Harvey Oswald defected to the Soviet Union in September 1959, married Soviet citizen Marina Prusakova, and returned to the United States in June 1962. His documented contacts with Soviet and Cuban officials — including a visit to the Soviet embassy in Mexico City weeks before the assassination — have fuelled claims that Oswald was a KGB asset and that the Soviet Union ordered the assassination of President Kennedy. Declassified CIA, FBI, and post-Soviet KGB records confirm Oswald's presence in the USSR and his Soviet contacts; they do not support the "Soviet-ordered hit" conclusion, which remains unsubstantiated.

The President's Commission on the Assassination of President Kennedy — the Warren Commission — delivered its report in September 1964 after a ten-month investigation. Its core conclusion, that Lee Harvey Oswald acted alone and fired three shots from the Texas School Book Depository, remains the consensus position among historians and forensic analysts. The Commission's methodology has attracted sustained legitimate criticism: it received incomplete evidence from the CIA and FBI; its timeline was compressed; witness selection was narrow; and key forensic findings were later revisited. The House Select Committee on Assassinations (HSCA) found "probable conspiracy" in 1979 based on acoustic evidence that a National Research Council panel subsequently rejected. Distinguishing valid process critiques from the broader "cover-up" conspiracy framing is the central challenge.

On November 17 2023, the OpenAI board of directors fired CEO Sam Altman without warning, triggering a five-day crisis in which nearly 700 employees threatened mass resignation and Microsoft pressured the board to reinstate him. Altman was reinstated on November 21 with a reconstituted board. Multiple framings of the event circulate as conspiracy claims: an "AI safety coup" by board members who believed Altman was recklessly commercialising dangerous technology; a "Microsoft-orchestrated power grab" to install compliant leadership; and allegations that board member Helen Toner's academic paper criticising OpenAI was the proximate trigger. Evidence partially supports the safety-framing; the Microsoft-coup framing is more contested; Toner's paper role is documented but disputed as decisive.

Governments have demonstrably conducted weather modification programs. Project Stormfury (1962–1983) attempted hurricane modification; Operation Popeye (1967–1972) used cloud seeding as a military weapon in Vietnam and was later declassified; China operates the world's largest state weather modification program today. These are established historical facts. The leap from confirmed historical programs to claims of ongoing covert weather warfare in 2024–2025 — or that unnamed actors are weaponising weather for geopolitical ends — is not supported by evidence.

Malcolm X was assassinated on February 21, 1965 at the Audubon Ballroom in New York City. Three men were convicted: Talmadge Hayer (who confessed), Muhammad Aziz, and Khalil Islam. In November 2021, Manhattan District Attorney Cyrus Vance vacated the convictions of Aziz and Islam after a reinvestigation found that the FBI and NYPD had withheld exculpatory evidence from the defense. Aziz and Islam had maintained their innocence for more than 55 years. The exoneration partially substantiates the claim that authorities had concealed their foreknowledge of threats to Malcolm X.

The 1943 FBI seizure of Nikola Tesla's papers and belongings from his New York hotel room within hours of his death. The seizure is well-documented; what was taken, what was sensitive, and whether technology was subsequently suppressed remains partly contested.

Claims that Freemasonry — a 300-year-old fraternal organization — exercises secret control over governments, the Catholic Church, and world finance through esoteric initiation rituals and networks.

A secret senior society at Yale University, founded 1832. Claims of Bush-family/CIA pipelines, elite control of US foreign policy, and occult initiation rituals are partially supported by documented facts and partially fabricated.

A private organization founded in 1973 by David Rockefeller to foster dialogue between North America, Europe, and Japan. Frequently cited alongside Bilderberg and Council on Foreign Relations as evidence of shadow world governance.

An annual private conference of ~130 political leaders, corporate executives, academics, and media figures that meets behind closed doors. Founded 1954, often alleged to be a shadow world government coordinating global policy.

An annual summer retreat held at a 2,700-acre private campground in California's redwoods since 1878, attended by business executives, politicians, and cultural figures. Centered on the "Cremation of Care" ritual — an allegorical pageant involving a 40-foot owl effigy.

The 1947 crash of a high-altitude Project Mogul balloon near Roswell, New Mexico that was briefly described by the US Army as a recovered "flying disc" before being reclassified as a weather balloon — and later, in 1994, as a classified Soviet nuclear-test surveillance balloon.

The theory that the Federal Reserve System is a private institution controlled by banking elites that manipulates the money supply, interest rates, and economic cycles for the benefit of the wealthy at the expense of ordinary citizens.

The debate over whether adding fluoride to public water supplies is a safe public health measure to prevent tooth decay, or a form of mass medication with potential health risks that the public cannot opt out of.
