He has been interviewed and has self published his views on various matters, including his belief in eugenics to prevent genetic degradation in a technological world, opposition to inter-racial relationships, the 9/11 Truther movement and other conspiracy theories that have gained him a following amongst the alt-right.

His mother, Mary Langan-Hansen (née Chappelle, 1932–2014), was the daughter of a wealthy shipping executive but was cut off from her family.

Langan returned to Bozeman and worked as a forest service firefighter for 18 months before enrolling at Montana State University–Bozeman.

[2] He 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.

[1] He used the proceeds to purchase a horse farm in Missouri, where he now lives with his wife Gina (née LoSasso), a clinical neuropsychologist.

He continued to use that pseudonym for some time in his membership of the Mega Society, and was listed in the Guinness Book of Records along with Marilyn vos Savant and Keith Raniere as one of just three people to have scored so highly on the test.

[14] IQ testing at the tail of the normal distribution has been criticised as being dubious as there are insufficient normative cases upon which to base a statistically justified rank-ordering.

"[19] The Mega Test's attempt to measure high IQ at the tail of the normal distribution has been academically evaluated.

Attempts to eke out discrimination at the hundredth or thousandth percentile were clearly overwhelmed by the test's standard error, given that there were only 48 questions.

[24] He refers to this thesis as "a true 'theory of everything', a cross between John Archibald Wheeler's 'Participatory Universe' and Stephen Hawking's 'Imaginary Time' theory of cosmology,"[2] additionally contending that with the CTMU he "can prove the existence of god, the soul and an afterlife, using mathematics.

[25] Asked what he would do if he were in charge, Langan stated his first priority would be to set up an "anti-dysgenics" project, and would prevent people from "breeding as incontinently as they like.

"[26]: 18:45  He argues that this would be to practice "genetic hygiene to prevent genomic degradation and reverse evolution" owing to technological advances suspending the process of natural selection.

[25]: §80 Langan's support of conspiracy theories, including the 9/11 Truther movement, as well as his opposition to interracial relationships, have contributed to his gaining a following among members of the alt-right and others on the far right.

[27][28] Langan has claimed that the George W. Bush administration staged the 9/11 attacks in order to distract the public from learning about the CTMU.
