Christopher Michael Langan (born March 25, 1952) is an American whose IQ was reportedly estimated to be "between 190 and 210".[1] In Morris 2001, Langan relates that he took what was billed as "the world's most difficult IQ test" in Omni magazine, and he gives his IQ as "somewhere between 190 and 210". As a result of his score, he has been described as "the smartest man in America" as well as "the smartest man in the world" by some journalists.[2]

Langan has developed a "theory of the relationship between mind and reality" which he calls the "Cognitive-Theoretic Model of the Universe" (CTMU).[3][4][5] Influenced by the works of John Archibald Wheeler and Stephen Hawking among others, the work's central thesis is that reality is a self-processing, self-referential language, embodying a dual aspect monism and consisting of "infocognition", or information that resides in "syntactic operators" within reality.[6]

Early life[edit]

Christopher Michael Langan was born in 1952 in San Francisco, California but spent most of his childhood in Montana. His mother, Mary Langan-Hansen (née Chappelle July 20, 1932 - July 1, 2014), was the daughter of a wealthy shipping executive but was cut off from her family. His biological father, Melvin Letman, died or disappeared before he was born. Owing to a combination of severed family ties and an absent father figure for her children, Mary was often pressured to adopt an economically itinerant lifestyle on behalf of her four children. This meant frequently living on violent Indian reservations in conditions of extreme poverty.[7][8]

During elementary school, Langan was repeatedly skipped ahead and was tormented by his peers. Langan claims he was brutally beaten by his stepfather, Jack Langan. Jack Langan denies this claim. Chris Langan recalled that his "stepfather constantly asked [Chris] difficult questions, and when I'd give him correct answers to those questions, he'd bat me in the mouth or something of that nature to let me know he didn't appreciate a guy trying to be smarter than he was."[9] At the age of twelve years, Langan began weight training, and forcibly ended the abuse by throwing his stepfather out of the house when he was fourteen, and telling him never to return.[10]

Langan attended high school but found himself spending his last years engaged mostly in independent study, due to relative indifference of his teachers in accommodating his pleas concerning his increasing need and capacity to absorb more advanced material. While left to his own studies, he started teaching himself "advanced math, physics, philosophy, Latin, and Greek".[4] He earned a perfect score on the SAT (pre-1995 scale) despite taking a nap during the test.[9]

Langan attended Reed College and later on Montana State University, however, faced with severe financial and transportation problems, and believing that he could teach his professors more than they could teach him, he dropped out.[4]

Later life[edit]

Langan took a string of labor-intensive jobs for some time, and by his mid-40s had been a construction worker, cowboy, Forest Service Ranger, farmhand, and, for over twenty years, a bouncer on Long Island.

Langan was also approached and contracted by Disney Research[11] and he previously worked for Virtual Logistix, a technology company.[3]

Langan said he developed a "double-life strategy": on one side a regular guy, doing his job and exchanging pleasantries, and on the other side coming home to perform equations in his head, working in isolation on his Cognitive-Theoretic Model of the Universe (CTMU).[4]

Intellectual pursuits[edit]


In 1999, Langan and others formed a non-profit corporation named the Mega Foundation to "create and implement programs that aid in the development of severely gifted individuals and their ideas" (the organization's designation for those with IQs of 164 or above).[3][9]

Langan told Muscle & Fitness magazine that "you cannot describe the universe completely with any accuracy unless you're willing to admit that it's both physical and mental in nature"[12] and that the CTMU "explains the connection between mind and reality, therefore the presence of cognition and universe in the same phrase".[13] Langan contends that anything sufficiently real to influence reality must be within reality, and that mind and reality are ultimately inseparable to the extent that they share common rules of structure and processing.[14] He calls his proposal "a true 'Theory of Everything', a cross between John Archibald Wheeler's 'Participatory Universe' and Stephen Hawking's 'Imaginary Time' theory of cosmology."[4] In conjunction with his ideas, Langan has claimed: "You can prove the existence of God, the soul and an afterlife, using mathematics."[9]

As far CTMU's critical reception is concerned, the CTMU has been sometimes criticized for what some perceive as convoluted language. Some critics argue that Langan's use of neologisms (or redefined terms) has made his exposition obscure. Some suggest this is deliberate. The CTMU, being a perpetual work in progress, has been partly characterized as a tautology by Mr. Langan. [15]

Asked about creationism, Langan has said:

"I believe in the theory of evolution, but I believe as well in the allegorical truth of creation theory. In other words, I believe that evolution, including the principle of natural selection, is one of the tools used by God to create mankind. Mankind is then a participant in the creation of the universe itself, so that we have a closed loop. I believe that there is a level on which science and religious metaphor are mutually compatible."[13]

In a 2014 radio interview, Langan said that he has worked on the P versus NP problem and thinks he can prove that P does not equal NP.[16]

In March 2017, Langan's article "An Introduction to Mathematical Metaphysics" was published in Cosmos and History: The Journal of Natural and Social Philosophy, Vol 13, No 2 (2017).[17]

In January 2018, Langan's article "Metareligion as the Human Singularity" was published in Cosmos and History: The Journal of Natural and Social Philosophy, Vol 14, No 1 (2018).[18]

Personal life[edit]

In 2004, Langan moved with his wife Gina (née LoSasso), a clinical neuropsychologist, to northern Missouri, where he owns and operates a horse ranch and undertakes activities for his Foundation.[19]

Langan does not belong to any religious denomination, explaining that he "can't afford to let [his] logical approach to theology be prejudiced by religious dogma".[13]
