The Piri Reis map is a genuine 1513 Ottoman world chart, one-third of which survives, that alternative-history writers claim depicts the coastline of Antarctica ice-free—proving a lost advanced or extraterrestrial civilization mapped the planet during the last Ice Age. Cartographic historians instead read the puzzling southern landmass as a distorted, wrapped rendering of South America's coast.

The recurring claim that polling stations hand out pencils so that the state, MI5, or a hidden 'establishment' can secretly rub out and rewrite votes. It is true that UK polling stations traditionally supply pencils and that voters may bring their own pen. But ballots are sealed, transported, and counted the same night under the direct scrutiny of candidates' agents and observers, no evidence of pencil-enabled vote-switching has ever been found, and election authorities across the UK, Canada, Australia and the US have repeatedly debunked the idea. Pencils are used for mundane practical reasons, not for tampering.

NESARA/GESARA is the belief that a secret law was passed that will cancel all debts, abolish the IRS, release vast hidden 'prosperity funds,' and revalue world currencies once it is finally 'announced.' It began as a real but never-introduced 1990s reform proposal that an internet writer transformed around 2000 into a conspiracy theory that has never once come true.

Göbekli Tepe is a genuine 11,600-year-old megalithic site in southeastern Turkey that pushed monumental architecture back to Stone Age hunter-gatherers. Popular writers, above all Graham Hancock, recast it as proof of a lost technologically advanced civilization, a claim mainstream archaeology does not support.

In 1976 NASA's Viking 1 orbiter photographed a mesa in the Cydonia region of Mars that, under low resolution and slanting sunlight, resembled a humanoid face. Fringe researchers argued it was an artificial monument built by a lost Martian civilization and that NASA covered up the truth, but higher-resolution imaging over the following decades resolved it into an ordinary eroded hill.

In February 1959, nine experienced Soviet hikers died under strange circumstances on a slope of the northern Ural mountains — their tent slashed open from inside, several bodies bearing severe internal injuries without external wounds, and faint radiation on some clothing. The unexplained deaths and Soviet secrecy spawned decades of theories ranging from secret weapons tests to yetis and UFOs, until modern investigations and a 2021 peer-reviewed study pointed to a rare delayed slab avalanche.

The Dulce Base legend claims a multi-level, jointly-operated human-alien facility hides beneath Archuleta Mesa near Dulce, New Mexico, complete with genetic experiments, a 'Nightmare Hall,' and a 1979 firefight between aliens and human security. No physical evidence for any such base has ever surfaced. The story's documented origin is far stranger than the myth: a real U.S. Air Force disinformation campaign, run through AFOSI, that targeted Albuquerque businessman Paul Bennewitz and helped manufacture a modern UFO legend.

Robert Temple's 1976 book The Sirius Mystery claimed the Dogon people of Mali held impossible ancient knowledge of Sirius B, an invisible white-dwarf companion star with a ~50-year orbit, taught to them by amphibious extraterrestrials called the Nommo. The claim rests on 1930s-40s ethnography by Marcel Griaule and Germaine Dieterlen. But a 1991 field restudy by anthropologist Walter van Beek found Dogon informants did not actually hold the Sirius-B lore Griaule reported, Sirius B's existence and orbital period were already well known to Western science before Griaule arrived, and Carl Sagan and others argue the knowledge, if genuine, reached the Dogon through ordinary human contact.

The claim that Bitcoin was secretly built by the NSA (or another intelligence agency) as a surveillance tool, honeypot, or stepping stone to a controllable cashless currency. Proponents point to two real facts: the NSA designed the SHA-256 hash function Bitcoin uses, and NSA cryptographers co-authored a 1996 paper on anonymous electronic cash. But no evidence connects the agency to Bitcoin's creation, the technology it uses is public and standardized, and the code and history point to an independent cypherpunk lineage.

A set of clay jars with copper cylinders and iron rods, found near Baghdad and dated to the Parthian or Sasanian era, are claimed by alternative-history writers to be ancient electric batteries — proof of a lost electrical technology used for electroplating, or even a gift from ancient astronauts. The jars are genuinely old and a jar-plus-two-metals arrangement really can produce a fraction of a volt, and replicas (including a famous MythBusters build) have generated current. But there are no wires, no connectors, no electroplated artifacts, and no textual record of electricity in antiquity. The mainstream archaeological reading — storage vessels for sacred scrolls or protective spells — fits the evidence far better.

UN Agenda 21 (1992) and its successor the 2030 Agenda for Sustainable Development (2015, the 17 SDGs) are non-binding, voluntary UN action plans on sustainable development. A conspiracy theory recasts them as a covert blueprint for one-world government, abolition of private property, forced urbanization and depopulation.

The Black Knight satellite is the belief that an artificial object of extraterrestrial origin, roughly 13,000 years old, has been silently orbiting Earth in a near-polar orbit. In reality it is a single 'legend' assembled from at least six unrelated, individually explained events, capped by 1998 NASA photos of a lost thermal blanket.

A 19-foot granite monument erected in 1980 near Elberton, Georgia, by an anonymous commissioner using the pseudonym 'R.C. Christian,' inscribed with ten 'guides' whose first line called to keep humanity under 500 million. Conspiracy theorists read it as a globalist/Illuminati blueprint for depopulation, and it was bombed and demolished in 2022.

The claim that artificial intelligence poses an existential or catastrophic risk to humanity has been advanced by Nick Bostrom ('Superintelligence,' 2014), Stuart Russell ('Human Compatible,' 2019), Eliezer Yudkowsky and the LessWrong rationalist community, and — in more measured form — by Geoffrey Hinton and Yoshua Bengio. The Future of Life Institute open letter (22 March 2023) calling for a six-month pause on large AI experiments attracted over 30,000 signatories. The Center for AI Safety statement (30 May 2023) was signed by Hinton, Bengio, Sam Altman, and Demis Hassabis. The AI Safety Summit at Bletchley Park (1-2 November 2023) convened 28 countries plus the EU. Counter-arguments from Andrew Ng, Yann LeCun, and Melanie Mitchell hold that existential framing overstates near-term risk and distracts from concrete algorithmic harms including bias and labour displacement.

Facebook discovered in December 2015 that Aleksandr Kogan's 'thisisyourdigitallife' app had harvested data from approximately 87 million users and transferred it to SCL Group/Cambridge Analytica. Facebook contacted Cambridge Analytica, obtained certifications of data deletion, and did not notify affected users. Internal documents produced in the 2018 FTC investigation showed Facebook had identified the policy enforcement gap but treated it as resolved by the deletion certifications. Christopher Wylie's whistleblower disclosures to the New York Times and The Guardian (17 March 2018) revealed that the data had not been deleted. Facebook paid a $5 billion FTC settlement (24 July 2019) and a $100 million SEC fine. The claim that Facebook knowingly concealed this data harvest from regulators and users is partially supported by the documentary record.

Section 230(c)(1) of the Communications Decency Act 1996 provides that no provider or user of an interactive computer service shall be treated as the publisher or speaker of any information provided by another information content provider. Drafted by Reps. Christopher Cox and Ron Wyden as a response to Stratton Oakmont v Prodigy (1995), it has since shielded Meta, Google, and X from liability for user-generated content. Critics — from the Knight First Amendment Institute to House Energy and Commerce Committee — argue the immunity is overbroad and enables platform censorship; defenders counter that removing it would chill free expression and destroy small platforms. Trump EO 13925 (28 May 2020) directed a review; it was revoked 21 January 2021. The Supreme Court dismissed federal-government censorship-collusion claims in Murthy v Missouri (26 June 2024) for lack of standing. The 'conspiracy' framing here is the claim that Big Tech lobbied to entrench and expand Section 230 to achieve permanent, unaccountable censorship power.

On 19 March 2020 President Trump called hydroxychloroquine a 'game-changer' for COVID-19 at a White House press briefing. The FDA granted an Emergency Use Authorization on 28 March 2020. Off-label prescribing spiked and Mehmet Oz promoted the drug on television. Two high-profile observational studies — in The Lancet (22 May 2020) and NEJM (1 May 2020) — appeared to show harm from HCQ; both were retracted on 4-5 June 2020 after the Surgisphere database underlying them was found to be fictitious (Sapan Desai, CEO). The FDA revoked the EUA on 15 June 2020. Large randomised trials — RECOVERY and WHO Solidarity — subsequently confirmed no meaningful benefit. The conspiracy framing is that HCQ was suppressed for political or commercial reasons; the reality is more complex: early fraudulent data damaged the evidentiary base, then rigorous trials ruled out benefit.

The Great Barrington Declaration (4 October 2020), signed by epidemiologists Jay Bhattacharya, Sunetra Gupta, and Martin Kulldorff, advocated 'focused protection' of the vulnerable over broad population lockdowns. The John Snow Memorandum (14 October 2020) offered a counter-statement signed by Devi Sridhar, Trish Greenhalgh, and others. Sweden's Anders Tegnell pursued a less restrictive approach. A Johns Hopkins meta-analysis (Herby, Jonung, and Hanke, January 2022) found lockdowns had minimal effect on COVID mortality in Europe and the US. The Royal Society published a competing evidence review in August 2023. Jay Bhattacharya was appointed HHS Director in 2025. This is a legitimate ongoing scientific and policy debate, distinct from conspiracy claims that lockdowns were designed for population control.

On 8 March 2020, Anthony Fauci told CBS 60 Minutes "people should not be walking around with masks." On 3 April 2020, the CDC reversed course and recommended universal cloth-mask use. Fauci later acknowledged in a December 2020 letter to Sinclair — and in a January 2021 BBC interview — that the initial messaging was shaped by concern that N95 supplies would be depleted for healthcare workers. The WHO made a similar reversal in June 2020. The episode is a documented public-health-communication failure debated in peer-reviewed literature (Brennan and Saad-Roy, Health Affairs, 2021). The conspiracy framing — that masks were always known to be useless and officials lied to control the public — conflates a real supply-driven communication decision with fabricated intent to deceive.

Beginning in the mid-1950s, an exchange programme between the University of Chicago economics department and the Catholic University of Chile sent Chilean students to study under Milton Friedman and Arnold Harberger. The resulting cohort — nicknamed the "Chicago Boys" and including Sergio de Castro, Pablo Baraona, Álvaro Bardón, and Jorge Cauas — implemented sweeping free-market reforms after the September 11 1973 coup that brought Augusto Pinochet to power. The reforms included mass privatisation of banking (1976-78) and pensions (1981 AFP system), steep tariff reductions, and central-bank independence. Their record is disputed: initial successes were followed by the severe 1981-83 recession and 1982 banking crisis. Naomi Klein's 'The Shock Doctrine' (2007) argued the reforms required authoritarian repression to implement; critics of Klein argue she overstated the causal link.

In 1989, economist John Williamson coined the term "Washington Consensus" in a paper listing ten policy prescriptions he observed as common ground among the IMF, World Bank, and US Treasury for Latin American reform: fiscal discipline, trade liberalisation, privatisation, deregulation, and capital-account openness. The policies were applied as conditions on IMF and World Bank loans through the 1990s and 2000s. Critics including Nobel laureate Joseph Stiglitz ("Globalization and Its Discontents," 2002) argued the conditionality was harmful and ideologically driven. The Asian financial crisis (1997-98) and Argentina's 2001-02 collapse became central exhibits. Williamson himself argued in 2004 that his original list was misrepresented as "neoliberalism" in its critics' use.

On Christmas Eve 1992, outgoing President George H.W. Bush pardoned six Iran-Contra figures: former Defense Secretary Caspar Weinberger, former Assistant Secretary of State Elliott Abrams, CIA officer Duane Clarridge, CIA officer Alan Fiers, former CIA Deputy Director of Operations Clair George, and former National Security Advisor Robert McFarlane. Independent Counsel Lawrence Walsh denounced the pardons as a "cover-up," arguing they cut off his investigation before Weinberger could stand trial. A Bush VP diary entry released after the pardons revealed that Bush himself had been fully briefed on the Iran-Contra operation: "I was one of the few people that knew fully the details." Walsh's Final Report (1993/1994) accused Bush of withholding information.

On 8 February 1951, a cervical cancer tissue sample was taken from Henrietta Lacks, a 31-year-old Black tobacco farmer, at Johns Hopkins Hospital without her informed consent — standard practice at the time. Researcher George Gey cultured the first immortal human cell line from the sample, designating it 'HeLa.' The cells were subsequently used in developing the Salk polio vaccine (1952), HPV-cancer research, in-vitro fertilization, and COVID-19 vaccine development. The Lacks family was unaware of the cell line until 1973. Rebecca Skloot's 'The Immortal Life of Henrietta Lacks' (2010) brought the case to mass public attention. On 1 August 2023 the family reached a settlement with Thermo Fisher Scientific over commercial use of HeLa cells.

On 2 May 1927, the Supreme Court ruled 8-1 in Buck v. Bell that Virginia's compulsory sterilization law was constitutional. Justice Oliver Wendell Holmes Jr. wrote the majority opinion, coining the phrase 'three generations of imbeciles are enough.' The sole dissenter, Justice Pierce Butler, did not write an opinion. Carrie Buck — the plaintiff, 17 years old, raped by her foster family's nephew and then institutionalized — was sterilized at the Virginia State Colony for Epileptics and Feebleminded. Later research by Stephen Jay Gould showed that Buck's daughter Vivian, cited in Holmes's opinion as the 'third generation of imbeciles,' achieved normal-to-honor-roll school performance before dying young. The ruling was cited by Nazi defendants at Nuremberg and has never been formally overturned.
