Modern flat Earth beliefs

{{Main|Flat Earth}}

Contrary to the popular belief that the Earth was generally believed to be flat until a few hundred years ago, the spherical shape of the Earth (and other celestial bodies) has been widely accepted in the Western world (and universally by scholars) since at least the Hellenistic period (323 BCE–31 BCE), with the first known measurement of Earth's circumference conducted by Eratosthenes.{{cite book |last1=Hutchings |first1=David |last2=Ungureanu |first2=James C. |title=Of popes and unicorns: science, Christianity, and how the conflict thesis fooled the world |date=2022 |publisher=Oxford University Press |location=New York, NY |isbn=0190053097}}{{cite web | url=https://www.livescience.com/24310-flat-earth-belief.html | title=Are Flat-Earthers Being Serious? | website=Live Science | date=16 December 2021 }}{{Cite web |last=Brazil |first=Rachel |date=2020-07-14 |title=Fighting flat-Earth theory |url=https://physicsworld.com/fighting-flat-earth-theory/ |access-date=2024-07-18 |website=Physics World |language=en-GB}}

It is only comparatively recently that the Flat Earth concept has grown widespread support, due to Samuel Rowbotham in the 19th century.

Flat Earth beliefs have had a recent resurgence since 2015, due to the internet.

Modern flat Earth belief originated with the English writer Samuel Rowbotham (1816–1884). Based on conclusions derived from his 1838 Bedford Level experiment, Rowbotham published the 1849 pamphlet titled Zetetic Astronomy, writing under the pseudonym "Parallax". He later expanded this into the book Earth Not a Globe, proposing the Earth is a flat disc centred at the North Pole and bounded along its southern edge by a wall of ice, Antarctica. Rowbotham further held that the Sun and Moon were {{Convert|3000|mi}} above Earth and that the "cosmos" was {{Convert|3100|mi}} above the Earth. He also published a leaflet titled The Inconsistency of Modern Astronomy and its Opposition to the Scriptures, which argued that the "Bible, alongside our senses, supported the idea that the Earth was flat and immovable and this essential truth should not be set aside for a system based solely on human conjecture".{{harvnb|Garwood|2007|p=46}}

Rowbotham and followers like William Carpenter gained attention by successful use of pseudoscience in public debates with leading scientists such as Alfred Russel Wallace.Nature 7 April 1870.{{Cite journal |title =The Form of the Earth—A Shock of Opinions |journal=The New York Times |date=10 August 1871 |url=https://timesmachine.nytimes.com/timesmachine/1871/08/10/78770850.pdf |archive-url=https://web.archive.org/web/20190711054039/https://timesmachine.nytimes.com/timesmachine/1871/08/10/78770850.pdf |archive-date=2019-07-11 |url-status=live |access-date= 2 November 2007 }}Hampden, John (1870): The Bedford Canal swindle detected & exposed.

In 1877, John Hampden produced a book A New Manual of Biblical Cosmography.{{cite book |title=The Discovery of America |date= 1892 |first= John |last= Fiske |page= [https://archive.org/details/discoveryameric13fiskgoog/page/n317 267] |url= https://archive.org/details/discoveryameric13fiskgoog |publisher= The Riverside Press}} Rowbotham also produced studies that purported to show that the effects of ships disappearing below the horizon could be explained by the laws of perspective in relation to the human eye.{{Cite book |author= Parallax (Samuel Birley Rowbotham) |title= Zetetic Astronomy: Earth Not a Globe |edition= Third | place= London |publisher= Simpkin, Marshall, and Co. |date=1881 |url=http://www.sacred-texts.com/earth/za/za32.htm}}

After Rowbotham's death, Lady Elizabeth Blount established the Universal Zetetic Society in 1893, whose objective was "the propagation of knowledge related to Natural Cosmogony in confirmation of the Holy Scriptures, based on practical scientific investigation". The society published a magazine, The Earth Not a Globe Review, which sold for twopence and remained active well into the early 20th century.{{cite book |last= Moore |first= Patrick |author-link= Patrick Moore |title= Can You Speak Venusian? |date= 1972 |isbn= 0-352-39776-4 |chapter-url= http://www.theflatearthsociety.org/library/books/Better%20and%20Flatter%20Earths%20%28Patrick%20Moore%29.pdf |archive-url=https://web.archive.org/web/20140521000355/http://www.theflatearthsociety.org/library/books/Better%20and%20Flatter%20Earths%20(Patrick%20Moore).pdf |archive-date=2014-05-21 |url-status=live |chapter= Better and Flatter Earths |publisher= Wyndham Publications }} A flat Earth journal, Earth: a Monthly Magazine of Sense and Science, was published between 1901 and 1904, edited by Lady Blount.{{harvnb|Garwood|2007|pp=155–159}} She held that the Bible was the unquestionable authority on the natural world and argued that one could not be a Christian and believe the Earth is a globe. Well-known members included E. W. Bullinger of the Trinitarian Bible Society, Edward Haughton, senior moderator in natural science in Trinity College Dublin and an archbishop. She repeated Rowbotham's experiments, generating some counter-experiments, but interest declined after the First World War. The Universal Zetetic Society "was revived under different names over the years—in 1956, 1972, and 2004". The movement gave rise to several books that argued for a flat, stationary Earth, including Terra Firma by David Wardlaw Scott.{{cite book |first= David |last = Wardlaw Scott |title=Terra Firma |year=1901 |url= https://archive.org/details/cu31924031764594 |access-date= December 13, 2010}}

Other notable flat Earthers from this time period include:

• William Carpenter, a printer originally from Greenwich, was a supporter of Rowbotham. Carpenter published Theoretical Astronomy Examined and Exposed – Proving the Earth not a Globe in eight parts from 1864 under the name Common Sense.{{cite book |url=https://books.google.com/books?id=oB1cxm_M-zUC |title= Theoretical astronomy examined and exposed, by 'Common sense' |year= 1864|last=Carpenter |first= William }} He later emigrated to Baltimore, where he published One Hundred Proofs the Earth is Not a Globe in 1885.{{cite book | first= William | last= Carpenter | title= One Hundred Proofs that the Earth is Not a Globe | place= Baltimore| publisher= William Carpenter| year= 1885 | url= https://www.gutenberg.org/files/55387/55387-h/55387-h.htm | via= Project Gutenberg}} He wrote: "There are rivers that flow for hundreds of miles towards the level of the sea without falling more than a few feet – notably, the Nile, which, in a thousand miles, falls but a foot. A level expanse of this extent is quite incompatible with the idea of the Earth's convexity. It is, therefore, a reasonable proof that Earth is not a globe", as well as: "If the Earth were a globe, a small model globe would be the very best – because the truest – thing for the navigator to take to sea with him. But such a thing as that is not known: with such a toy as a guide, the mariner would wreck his ship, of a certainty! This is a proof that Earth is not a globe."
• John Jasper, an American slave turned prolific preacher, and friend of Carpenter's, echoed his friend's sentiments in his most famous sermon "The Sun do move", preached over 250 times, always by invitation. In a written account of his sermon, published in The Richmond Whig of March 19, 1878, Jasper says he would frequently cite the verse "I saw four angels standing on the four corners of the earth"Rev. 7:1. and follow up by arguing: "So we are living on a four-cornered earth; then, my friends, will you tell me how in the name of God can an earth with four corners be round!" In the same article he argued: "if the earth is like others say, who hold a different theory, peopled on the other side, those people would be obliged to walk on the ground with their feet upward like flies on the ceiling of a room".Hatcher (1908, [https://archive.org/details/johnjasperunmatc00hatciala/page/20 p. 20]), Garwood (2007, p. 165), Randolph (1884, [https://docsouth.unc.edu/neh/jasper/jasper.html#p47 pp. 47–53]).
• In Brockport, New York, in 1887, M. C. Flanders argued the case of a flat Earth for three nights against two scientific gentlemen defending sphericity. Five townsmen chosen as judges voted unanimously for a flat Earth at the end. The case was reported in the Brockport Democrat.The Earth: Scripturally, Rationally, and Practically Described. A Geographical, Philosophical, and Educational Review, Nautical Guide, and General Student's Manual, n. 17 (November 1, 1887), p. 7.

• Joseph W. Holden of Maine, a former justice of the peace, gave numerous lectures in New England and lectured on flat-Earth theory at the Columbian Exposition in Chicago. His fame stretched to North Carolina, where the Statesville Semi-weekly Landmark recorded at his death in 1900: "We hold to the doctrine that the Earth is flat ourselves and we regret exceedingly to learn that one of our members is dead."Garwood (2007).
• In 1898, during his solo circumnavigation of the world, Joshua Slocum encountered a group of flat-Earthers in Durban, South Africa. Three Boers, one of them a clergyman, presented Slocum with a pamphlet in which they set out to prove that the world was flat. Paul Kruger, President of the Transvaal Republic, advanced the same view: "You don't mean round the world, it is impossible! You mean in the world. Impossible!"{{cite book | first= Joshua | last = Slocum | title= Sailing Alone Around the World | place= New York | publisher= The Century Company | year= 1900 |chapter = 17–18 | chapter-url= http://www.ibiblio.org/eldritch/js/saaw.htm}}
• From 1915 to 1942 Wilbur Glenn Voliva, who in 1906 took over the Christian Catholic Church, a Pentecostal sect that established a utopian community in Zion, Illinois, preached flat Earth doctrine. He used a photograph of a {{convert|12|mi|adj=on|spell=in}} stretch of the shoreline at Lake Winnebago, Wisconsin, taken {{convert|3|ft|cm|spell=in}} above the waterline to prove his point. When the airship Italia disappeared on an expedition to the North Pole in 1928, he warned the world's press that it had sailed over the edge of the world. He offered a $5,000 award ({{Inflation|US|5000|1931|fmt=eq}}) for proving that the Earth is not flat, under his own conditions.{{cite web |url=http://blog.modernmechanix.com/2006/05/19/5000-for-proving-the-earth-is-a-globe/ |title=$5,000 for Proving the Earth is a Globe |work=Modern Mechanix |date=May 19, 2006 |access-date=February 9, 2013 |archive-url=https://web.archive.org/web/20110411223327/http://blog.modernmechanix.com/2006/05/19/5000-for-proving-the-earth-is-a-globe/ |archive-date=April 11, 2011 |url-status=dead }} Teaching a globular Earth was banned in the Zion schools, and the message was transmitted on his WCBD radio station.
• Along with those who followed him, Frank Cherry (died 1963), the founder of the Black Hebrew Israelite religion, taught the existence of a flat Earth "surrounded by three layers of heaven."{{cite book |last1=Gallagher |first1=Eugene V. |title=Introduction to New and Alternative Religions in America [Five Volumes] |date=2006 |publisher=Greenwood Publishing Group |isbn=978-0-313-05078-7 |page=73 |language=English|quote=...he accepted the collection of Jewish law known as the Talmud as the ultimate authority on religious matters. Like many black Israelites and black Muslims, Cherry stigmatized Southern black culture, forbidding his followers to eat pork, drink heavily, or observe Christian holidays. He also separated himself from African American Christianity by forbidding pianos, public collections, emotional expression in worship, or speaking in tongues. ... Services began and ended with a prayer said while facing east ... Prophet Cherry's theology was strongly millenarian, black nationalist, and idiosyncratic. He emphasized strict adherence to the Ten Commandments, and his followers believed in a square Earth surrounded by three layers of heaven. He claimed that Jesus was black and would return in the year 2000 and raise all the saints who obeyed the Ten Commandments and the teachings of Prophet Cherry. Cherry denigrated white Jews as interlopers and frauds and vilified them for denying the divinity of Jesus. Prophet Cherry passed away in 1963 and was succeeded by his son Prince Benjamin F. Cherry.}}

In 1956, Samuel Shenton created the International Flat Earth Research Society, better known as the "Flat Earth Society", as a successor to the Universal Zetetic Society, running it as "organising secretary" from his home in Dover, England.{{Cite news|url=https://www.newspapers.com/clip/17484882/the_cincinnati_enquirer|title=So now we know: The Earth is not only flat—it's motionless, too|last=Gilmore|first=Eddy|date=26 March 1967|work=The Cincinnati Enquirer|access-date=15 February 2018|page=26–I|url-access=limited|via=Newspapers.com}} {{free access}} Readable clippings in four parts: [https://www.newspapers.com/clip/17484925/the_cincinnati_enquirer/ 1] • [https://www.newspapers.com/clip/17484950/the_cincinnati_enquirer/ 2] • [https://www.newspapers.com/clip/17484958/the_cincinnati_enquirer/ 3]

• [https://www.newspapers.com/clip/17484965/the_cincinnati_enquirer/ 4] Given Shenton's interest in alternative science and technology, the emphasis on religious arguments was less than in the predecessor society.{{harvnb|Garwood|2007|pp=220–225}} This was just before the Soviet Union launched the first artificial satellite, Sputnik; he responded: "Would sailing round the Isle of Wight prove that it were spherical?

His primary aim was to reach children before they were convinced about a spherical Earth. Despite plenty of publicity, the space race eroded Shenton's support in Britain until 1967, when he started to gain attention during the Apollo program. When satellite images showed Earth as a sphere, Shenton remarked: "It's easy to see how a photograph like that could fool the untrained eye".{{cite web|last=Schadewald|first=RJ |url= http://ncse.com/cej/3/3/six-flood-arguments-creationists-cant-answer |title= Six "flood" arguments creationists can't answer |publisher= National Center for Science Education |access-date=24 April 2010}} Later asked about similar photographs taken by astronauts, he attributed curvature to the use of wide-angle lens, adding, "It's a deception of the public and it isn't right".

In 1969, Shenton persuaded Ellis Hillman, a Polytechnic of East London lecturer, to become president of the Flat Earth Society after attempts to convince Eden Thomas, a former chairman, to take on the role; but there is little evidence of any activity on his part until after Shenton's death, when he added most of Shenton's library to the archives of the Science Fiction Foundation he helped to establish.{{harvnb|Garwood|2007|pp=320}}

Shenton died in 1971. Charles K. Johnson, a correspondent from California, inherited part of Shenton's library from Shenton's wife; he incorporated and became president of the International Flat Earth Research Society of America and Covenant People's Church in California. Over the next three decades, under his leadership, the Flat Earth Society grew to a reported 3,500 members.{{cite news |url= https://www.nytimes.com/2001/03/25/us/charles-johnson-76-proponent-of-flat-earth.html |title= Charles Johnson, 76, Proponent of Flat Earth |date= 25 March 2001 |access-date= 27 December 2013 |work= The New York Times |first= Douglas |last= Martin}}

Johnson spent years examining the studies of flat- and round-Earth theories and proposed evidence of a conspiracy against flat Earth: "The idea of a spinning globe is only a conspiracy of error that Moses, Columbus, and FDR all fought..." His article was published in the magazine Science Digest in 1980. It goes on to state: "If it is a sphere, the surface of a large body of water must be curved. The Johnsons have checked the surfaces of Lake Tahoe and the Salton Sea without detecting any curvature."{{cite web |author=Robert J.

Johnson issued many publications and handled all membership applications. The most famous publication was Flat Earth News, a quarterly, four-page tabloid. Johnson paid for these publications through annual member dues costing US$6 to US$10 over the course of his leadership. Johnson cited the Bible for his beliefs, and he saw scientists as pulling a hoax which would replace religion with science.

The Flat Earth Society recruited members by speaking against the US government and all its agencies, particularly NASA. Much of the society's literature in its early days focused on interpreting the Bible to mean that the Earth is flat, although they did try to offer scientific explanations and evidence.

Eugenie Scott called the group an example of "extreme Biblical-literalist theology: The earth is flat because the Bible says it is flat, regardless of what science tells us".{{cite journal|last=Scott|first=Eugenie|year=1997|title=Antievolution and Creationism in the United States|url=http://www.kean.edu/~bregal/docs/Scott.history%20of%20creat.pdf|journal=Annual Review of Anthropology|volume=26|pages=263–289|doi=10.1146/annurev.anthro.26.1.263|author-link=Eugenie Scott|access-date=8 December 2011|url-status=dead|archive-url=https://web.archive.org/web/20120605065015/http://www.kean.edu/~bregal/docs/Scott.history%20of%20creat.pdf|archive-date=5 June 2012}}

According to some flat Earthers, the Flat Earth Society is a government-controlled organization whose true purpose is to make ridiculous claims about flat Earth and therefore discredit the flat Earth movement.{{cite web |last1=Picheta |first1=Rob |title=The flat-Earth conspiracy is spreading around the globe.

According to Charles K. Johnson, the membership of the group rose to 3,500 under his leadership but began to decline after a fire at his house in 1997 which destroyed all of the records and contacts of the society's members. Johnson's wife, who helped manage the membership database, died shortly thereafter. Johnson himself died on 19 March 2001.{{cite web|last=Cole|first=John R.|url=http://ncse.com/rncse/21/3-4/flat-earth-society-president-dies |title=Flat Earth Society President Dies|publisher=National Center for Science Education |year=2001 |access-date=15 June 2009}}{{cite web |author=Donald E.

The parodic intention of the Society appeared in the writings of Ferrari, as he attributed everything from gender to racial inequality on the globularist and the spherical Earth model.{{Cite journal|last=Ferrari|first=Leo Charles|year=1975|title=Feminism and education in a Flat Earth perspective|url=http://mje.mcgill.ca/index.php/MJE/article/download/7006/4948|journal=McGill Journal of Education|volume=X|issue=1|pages=77–81}} Ferrari also claimed to have nearly fallen off "the Edge" of the Earth at Brimstone Head on Fogo Island.{{cite book|last=Colombo|first=John R|title=Canadian Literary Landmarks|date=1984|publisher=Dundurn|isbn=978-0888820730|page=19}}

In Italy, there are no centralised societies on flat Earth. However, since the 2010s, small groups of conspiracy theorists, who carry out meetings, started to emerge and to spread flat Earth theories. Among these are Calogero Greco, Albino Galuppini and Agostino Favari, who in 2018–2019 organised several meetings in Palermo, Sicily, with an entry price of €20.{{cite web|language=it|title=Terrapiattisti a Palermo: "Lo sbarco sulla luna è una invenzione" (Flat Earth in Palermo: "Moon landing is fiction")|date=11 May 2019|access-date=22 July 2019|website=Adnkronos|url=https://www.adnkronos.com/fatti/cronaca/2019/05/11/terrapiattisti-palermo-sbarco-sulla-luna-una-invenzione_qp89IcCYJyNifqCYnb9HQK.html?refresh_ce}}{{cite web|language=it|url=https://www.ilmessaggero.it/scienza/terrapiattisti_convegno_palermo_ultime_notizie_oggi_12_maggio_2019-4486635.html|date=12 May 2019|access-date=22 July 2019|title=Terrapiattisti a Palermo, ma Beppe Grillo non c'è.

Among their claims, some include:

• NASA is similar to Disneyland and that astronauts are actors.
• The April 2019 photo of the supermassive black hole at the core of the supergiant elliptical galaxy Messier 87 is fake.
• The proof Earth is flat can be demonstrated with a filled bottle where, if placed horizontally, water never curves.

Out of the necessity to explain photographs of the earth in space, the observations of astronauts, why all major institutions such as governments, media outlets, schools, scientists, and airlines assert that the world is a sphere, etc., modern flat-Earthers very commonly embrace some form of conspiracy theory. As Darryle Marble, a speaker at the Flat Earth Conference, told his audience, after watching hours of YouTube conspiracy videos on Sandy Hook, 9/11, false flags, the Bilderbergers, Rothschilds, Illuminati – "Each thing started to make that much more sense. I was already primed to receive the whole flat-Earth idea, because we had already come to the conclusion that we were being deceived about so many other things. So of course they would lie to us about this."

Conspiracy belief is often intertwined with conservative Christian belief. According to internet influencer Rob Skiba, "the ultimate motivation" of the (alleged) conspiracy of a round earth in space, "many of us have come to believe, is hiding God." Reading the Bible, "when you break down the text of what it represents, there's no way you can get a spinning heliocentric globe out of anything in the Bible." (According to author Alan Burdick, "in style and substance, the flat-Earth movement is a close cousin of creationism.")

Flat-Earthers tend to not trust observations they have not made themselves, and often distrust or disagree with each other.{{cite web |url=https://www.bostonglobe.com/ideas/2017/10/28/what-does-take-believe-world-flat/0gdgl2JMPhBpgJK5mGXPkI/story.html |title=What does it take to believe the world is flat? |date=28 October 2017 |first=Courtney|last=Humphries|website=The Boston Globe }} Patricia Steere admitted in Behind the Curve that she wouldn't believe an event like the Boston Marathon bombing was real unless she had gotten her own leg blown off. Flat Earth believers in the documentary also professed belief in conspiracy theories about vaccines, genetically modified organisms, chemtrails, 9/11, and transgender people; some said dinosaurs and evolution were also fake, and that heliocentrism is a form of Sun worship.

The scientific experts in Behind the Curve pointed to confirmation bias as a way to maintain a counterfactual belief, by cherry-picking only supporting evidence, and dismissing any disconfirming evidence as part of the purported global conspiracy.around 30 minutes and 49 minutes

Some flat Earth believers, such as authors Zen Garcia and Edward Hendrie, cite the Christian Bible as evidence. Some critics of the flat Earth idea, such as astronomer Danny R. Faulkner, are young Earth creationists and attempt to explain away the Bible's supposed flat Earth language.{{cite magazine |last=Branch |first=Glenn |authorlink=Glenn Branch |date=July–August 2020 |title=Flat-Earthery Will Get You Nowhere |url=https://skepticalinquirer.org/2020/06/flat-earthery-will-get-you-nowhere/ |url-status= |magazine=Skeptical Inquirer |location=Amherst, New York |publisher=Center for Inquiry |archive-url=https://web.archive.org/web/20201003202205/https://skepticalinquirer.org/2020/06/flat-earthery-will-get-you-nowhere/ |archive-date=3 October 2020 |access-date=24 March 2021}}

On 3 May 2018, Steven Novella analysed the modern belief in a flat Earth, and concluded that, despite what most people think about the subject, the believers are being sincere in their belief that the Earth is flat, and are not "just saying that to wind us up". He stated that:

The British sceptical activist Michael Marshall attended the annual Flat Earth UK Convention on 27–29 April 2018 and noted disagreement on several views among believers in a flat Earth. To Marshall, one of the most telling moments at the convention was the "Flat Earth Addiction" test that was based on a checklist used to determine whether someone is in a cult, without the convention attendees realising the possibility of themselves being in a cult.

Based on the speakers at the 2018 UK's Flat Earth UK Convention, believers in a flat Earth vary widely in their views. While most agree upon a disc-shaped Earth, some are convinced the Earth is diamond-shaped. Furthermore, while most believers do not believe in outer space and none believe humans have ever travelled there, they vary widely in their views of the universe.{{cite news |last1=Marshall |first1=Michael|author-link1=Michael Marshall (skeptic) |title=The universe is an egg and the moon isn't real: notes from a Flat Earth conference |url=https://www.theguardian.com/science/blog/2018/may/02/the-universe-is-an-egg-and-the-moon-isnt-real-notes-from-a-flat-earth-conference |newspaper=The Guardian |access-date=16 September 2018|date=2 May 2018}} (Flat Earth International Conferences, organized by Robbie Davidson, are unaffiliated with the Flat Earth Society.

Filmmakers of Behind the Curve attended another flat Earth conference at which a substantial number of people believed the Earth was an infinite plane, potentially with more continents beyond the purported circular ice wall of Antarctica.

Research by Carlos Diaz Ruiz and Tomas Nilsson on the arguments that flat Earthers wield, shows three factions, each one subscribing to its own set of beliefs.{{Cite journal |last1=Diaz Ruiz |first1=Carlos |last2=Nilsson |first2=Tomas |date=16 May 2022 |title=Disinformation and Echo Chambers: How Disinformation Circulates in Social Media Through Identity-Driven Controversies |url=http://journals.sagepub.com/doi/10.1177/07439156221103852 |journal=Journal of Public Policy & Marketing |volume=42 |issue=1 |pages=18–35 |doi=10.1177/07439156221103852 |s2cid=248934562}}

The first faction subscribes to a faith-based conflict in which atheists use science to suppress the Christian faith. Their argument is that atheists use pseudo-science – evolution, Big Bang, and the round Earth – to make people believe that God is an abstract idea, not real. Instead, their arguments use the Scripture – word-by-word – to support an argument that enables God to really exist. This faction frames flat-Earth arguments as revelatory. (For example, a literal interpretation of Revelation 7 — "I saw four angels standing at the four corners of the earth ..." — indicates the earth must have four corners.) This is in spite of the fact that a circular flat earth would also not have corners, contradicting the central model of flat earth. This contradiction seems to imply that God created a 2D quadrilateral or 3D tetrahedral earth.

The second faction believes in an overarching conspiracy for knowledge suppression. Building upon the premise that knowledge is power, the flat Earth conspiracy argues that a shadowy group of "elites" control knowledge to remain in power. In their view, lying about the fundamental nature of the Earth primes the population to believe a host of other conspiracies. This faction frames flat-Earth arguments as liberatory.

The third faction believes that knowledge is personal and experiential. They are dismissive of knowledge that comes from authoritative sources, especially book knowledge. This faction would like to find out themselves whether the Earth truly is round or flat. Because they distrust book knowledge and mathematical proof, this faction believes that the Earth is flat because their observations and lived experiences make it appear that the Earth is a flat surface. This faction frames flat-Earth arguments as experimental.

Fellow flat earthers are not exempt from distrust and belief that they may be in cahoots with round earthers. In Behind the Curve, conference attendees were warned against attending by Math Powerland, also known as Matt Boylan, who posted videos alleging others were working for the CIA or Warner Brothers. At the 2017 Flat Earth conference:

{{blockquote|[S]everal speakers made reference to "shills" within the community, people purporting to espouse the theory but who in fact belong to some deep-state counterintelligence program aimed at making the movement seem laughable. In 2016, [Eric Dubay], of the "200 Proofs" video, called out Mark Sargent, Jeran Campanella, and other figures as "suspected controlled opposition shills," and last year in a radio interview he called the November conference a "shill-fest." Even the flat-Earth bureaucracy is suspect. At the end of the conference's second day, a panelist mentioned a plan to set up a nonprofit to carry on the work. This brought a rebuke from a woman in the audience. "You had me up until I heard the gentleman say, 'The reason we had to scramble to get the 501(c)(3),{{' "}} she said. "In my research, I found out that's a Luciferian contract."}}

Organisations sceptical of fringe beliefs have occasionally performed tests to demonstrate the local curvature of the Earth. One of these, conducted by members of the Independent Investigations Group of the Center for Inquiry, at the Salton Sea on 10 June 2018 was attended also by supporters of a flat Earth, and the encounter between the two groups was recorded by the National Geographic Explorer. This experiment successfully demonstrated the curvature of the Earth via the disappearance over distance of boat-based and shore-based targets. IIG founder Jim Underdown reported that the flat Earth supporters in attendance immediately rejected the results, denying the validity of the demonstration after the fact, and the discussion degenerated into tangents about Moon landing conspiracy theories and alleged NASA cover-ups.{{cite journal |last1=Underdown |first1=James |author-link1=James Underdown |title=Commentary: The Salton Sea Flat Earth Test: When Skeptics Meet Deniers |journal=Skeptical Inquirer |date=2018 |volume=42 |issue=6 |pages=14–15}}{{cite web |last1=Underdown |first1=Jim |author-link1=James Underdown |title=The Salton Sea Flat Earth Test: When Skeptics Meet Deniers |url=https://www.csicop.org/si/show/the_salton_sea_flat_earth_test_when_skeptics_meet_deniers |website=CSICOP.org |publisher=CFI |access-date=24 February 2019 |archive-url=https://web.archive.org/web/20190224135255/https://www.csicop.org/si/show/the_salton_sea_flat_earth_test_when_skeptics_meet_deniers |archive-date=24 February 2019|url-status=live|date=November 2018 }}

The 2018 documentary Behind the Curve followed two groups of American flat Earth believers who were attempting to gather first-hand empirical proof for that belief. One group from the YouTube show GlobeBusters used a ring laser gyroscope in an attempt to show the Earth was not rotating. Instead, they detected the actual 15-degree-per-hour rotation of the Earth, a measurement they dismissed as corrupted by the device somehow picking up the rotation of the "firmament". Another group used lasers in an attempt to show a several-mile stretch of water is perfectly flat by measuring the distance between the water level and the laser beam along three vertical posts. They were unable to align the beam as they expected to because the surface of the still water was in fact bent by several feet over the distance measured; the experiment was dismissed as inconclusive.{{Cite AV media |url=https://www.youtube.com/watch?v=bZ_zDG6zL58 |title=Behind the Curve |date=2018-12-16 |last=YouTube Movies |access-date=2025-05-15 |via=YouTube}}

Behind the Curve illustrated how flat Earth believers rely on poorly-verified claims. Mark Sargent claimed to have watched flightaware.com for a very long time to check if any flights traveled between continents in the southern hemisphere, which in his disc model would be much further apart than they are on the globe. He stated that he saw no such flights, and took this as evidence for the disc model. Caltech astrophysicist Hannalore Gerling-Dunsmore went to the site and immediately found flights that contradicted Sargent's claims.starting at around 11 minutes. {{cite web |title=Behind the Curve |url=https://www.youtube.com/watch?v=bZ_zDG6zL58 |website=YouTube |access-date=31 July 2023 |date=2018}}{{cite web |url=https://flightaware.com/ |access-date=11 Feb 2022 |title=Real-time Worldwide Flight Traffic}} (Gerling-Dunsmore's claims were verified on this date at 03:30 UTC, though not all flights were visible when fully zoomed out - a possible source of confusion.)

In 2017, "the Tunisian and Arab scientific and educational world" had a scandal when a Ph.D. student at the University of Sfax in Tunisia submitted a Ph.D. dissertation "declaring Earth to be flat, unmoving, young (only 13,500 years of age), and the centre of the universe".{{cite web|last1=Guessoum|first1=Nidhal|title=PhD thesis: The earth is flat|url=http://gulfnews.com/opinion/thinkers/phd-thesis-the-earth-is-flat-1.2009202|work=Gulf News|date=10 April 2017 |access-date=19 August 2017}} In 2018, astronomer Yaël Nazé analyzed the controversy over the dissertation.

Of course, the easy response here would be to get a good laugh out of flat earthers grappling with their model being proved wrong and then feel thankful for Duffy and whoever has been promoting him putting on the event.

In this holiday season, many of us are gathering with family members who have drastically different scientific, political or theological views than us.

But despite the fact I personally think everyone involved in this “Final Experiment” has significant scientific, political and theological problems, there was something deeply human in their togetherness that is worth noting. (...) }}

Behind the Curve{{'}}s filmmakers spoke with several people who said that as a result of their flat Earth beliefs they had lost romantic partners and no longer spoke to many friends and family. One said he was tired of being told he was an idiot. The Facebook group Flat Earth Match is a dating site used by some to find romantic partners who share these beliefs. Experts pointed out that after social ties to people outside the flat Earth community are lost, one consequence of abandoning the flat Earth belief would be loss of all remaining relationships.{{citation needed|date=February 2024}}

Caltech physicist Spiros Michaelakis stated that instead of denigrating flat Earthers, scientists should do a better job of teaching scientific facts. Various scientific and medical experts in the documentary supported improving scientific literacy and avoiding marginalization of flat Earthers. They pointed out that people who distrust all of science, including truths about vaccines, evolution, and climate change, would make poorly informed decisions, and that people who do not exercise the skill of critical thinking can be easily manipulated. They also pointed out that some believers were motivated to spread false ideas, and that because these ideas are unconstrained by facts they can mutate and become less harmless than a mere belief about the shape of the Earth.Behind the Curve, starting around 1 hour, 8 minutes

The term flat-Earth-man, used in a derogatory sense to mean anyone who holds ridiculously antiquated or impossible views, predates the more compact flat-earther. It was recorded in 1908: "Fewer votes than one would have thought possible for any human candidate, were he even a flat-earth-man."

According to the Oxford English Dictionary, the first use of the term flat-Earther was in 1934 in Punch magazine: "Without being a bigoted flat-earther, [Mercator] perceived the nuisance ... of fiddling about with globes ... in order to discover the South Seas."
