Conspiracy theories, rigorously examined.

We steelman the claim, then follow the evidence. Some theories were true. Most aren't. Here's how to tell the difference.

Conspiracy theories deserve serious examination — not mockery and not credulity. Some dismissed as paranoia, like MKUltra and NSA mass surveillance, turned out to be true. Others, like flat earth, have been thoroughly debunked by centuries of evidence. The difference matters. Conspirafy takes every theory seriously enough to steelman it fairly, then rigorously test it against the evidence. Every theory gets a clear verdict: confirmed, debunked, or somewhere in between.

We're not "both sides." We're pro-evidence. Every theory is examined for logical fallacies, red flags, and source quality. When a theory has been confirmed by declassified documents, we say so. When it's been debunked, we say that clearly too — with the evidence to back it up.

AI existential risk / 'AI doomer' debate (2014-present)
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.

Section 230 platform-immunity debate (1996-present)
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.

Meta/Facebook knowledge of Cambridge Analytica before Mar 2018 (2015-18)
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.

COVID lockdown effectiveness public-health debate (2020-present)
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.

CDC mask-recommendation reversal (Feb-Apr 2020)
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.

Hydroxychloroquine COVID promotion and suppression (Mar-Jun 2020)
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.

Bush Sr Iran-Contra pardons (Dec 24 1992)

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.

American eugenics movement (1907-present)

Indiana enacted the first compulsory sterilization law in 1907, signed by Governor J. Frank Hanly. Between 1907 and 1979, approximately 70,000 Americans were forcibly sterilized across 32 states. California alone accounted for roughly 20,000 sterilizations. The Eugenics Record Office at Cold Spring Harbor — funded by Carnegie and Rockefeller — coordinated research and policy advocacy. Madison Grant's 'The Passing of the Great Race' (1916) and the Immigration Act of 1924 translated eugenic pseudoscience into federal law. North Carolina's sterilization programme continued into the 1970s; ICE detention sterilization claims emerged as recently as 2020. Reparations programmes in North Carolina (2013) and Virginia (2015) represent partial acknowledgement of state-sanctioned harm.

Columbine 'Trench Coat Mafia' bullied-loners myth (Apr 20 1999)

On April 20 1999 Eric Harris (18) and Dylan Klebold (17) killed 13 people and injured 24 at Columbine High School, Littleton CO, before dying by suicide. Initial reporting — including a USA Today front page and a Time cover captioned 'The Monsters Next Door' — framed the pair as outcast goths bullied into revenge by peers. Dave Cullen's 2009 book 'Columbine' and FBI profiler Dwayne Fuselier's psychological analysis demolished that framing: Harris met criteria for clinical psychopathy on the Hare PCL-R scale; Klebold was severely depressed and suicidal; neither was a bullied loner in the sense the media narrative required. The 'Trench Coat Mafia' was a separate clique whose members had graduated before the attack; Harris and Klebold wore the dusters for tactical concealment, not group identity.

Protocols of the Elders of Zion (1903-present)

The Protocols of the Elders of Zion is an antisemitic forgery first published in the Russian newspaper Znamya in 1903 by Pavel Krushevan, with later editions promoted by Pyotr Rachkovsky of the Okhrana (Tsarist secret police). The text plagiarises Maurice Joly's 1864 satirical Dialogue aux Enfers (targeting Napoleon III) and elements of Hermann Goedsche's 1868 novel Biarritz. Times of London journalist Philip Graves documented the direct plagiarism in August 1921. Henry Ford serialised the text in the Dearborn Independent (1920–22). Swiss Bern Trial (1933–35) declared it a forgery, though overturned on technicality in 1937. The text has been used by the Hamas Charter (1988), Iranian state media, and white supremacist organisations. Verdict: debunked.

RFK Jr. anti-vaccine activism / Children's Health Defense (1998-present)

Robert F. Kennedy Jr. has promoted vaccine-autism and vaccine-injury claims since the early 2000s, founding the World Mercury Project (later Children's Health Defense) to advance those claims. The foundational vaccine-autism link derived from Andrew Wakefield's 1998 Lancet paper, retracted in 2010 after investigation found data fabrication and undisclosed financial conflicts; Wakefield was struck off the UK General Medical Council. The thimerosal-mercury hypothesis Kennedy championed was addressed by the 2004 IOM report and by Hviid et al. (2003, NEJM) among many subsequent studies, all finding no causal link. Kennedy was nominated as HHS Secretary in November 2024 and confirmed in 2025, bringing the claims into active US public health policy.
