|Type||High IQ society|
Founded in 1982 by Ronald K. Hoeflin to facilitate psychometric research, the Mega Society is a high IQ society open to people who have scored at the one-in-a-million level on a test of general intelligence claimed to be able to discriminate at that level.
The public profile of the Mega Society increased with the publication of the Mega Test in 1985 by Hoeflin.
Criteria for acceptance
No professionally designed and validated IQ test claims to distinguish test-takers at the one-in-a-million level of rarity of score. The standard score range of the Stanford-Binet IQ test is 40 to 160. The standard scores on most other currently normed IQ tests fall in the same range. A score of 160 corresponds to a rarity of about 1 person in 30,000 (leaving aside the issue of error of measurement common to all IQ tests), which falls short of the Mega Society's 1 in a million requirement. IQ scores above this level are dubious as there are insufficient normative cases upon which to base a statistically justified rank-ordering. High IQ scores are less reliable than IQ scores nearer to the population median.
The Mega Society accepts members on the basis of untimed, unsupervised IQ tests that the test author claims have been normalized using standard statistical methods. There is controversy about whether these tests have been properly validated. The Mega test specifically is described as a "nonstandardized test" by a psychologist who wrote a 2012 book on the history of IQ testing.
The society's journal, called Noesis since July 1987, has been published since January 1982, when it was called the Circle. Currently, the journal is published on an irregular basis.

The concerns associated with SEMs [standard errors of measurement] are actually substantially worse for scores at the extremes of the distribution, especially when scores approach the maximum possible on a test ... when students answer most of the items correctly. In these cases, errors of measurement for scale scores will increase substantially at the extremes of the distribution. Commonly the SEM is from two to four times larger for very high scores than for scores near the mean (Lord, 1980).

From the article: "Although the approach that Hoeflin takes is interesting, inventive, intellectually stimulating, and internally consistent, it violates many good psychometric principles by overinterpreting the weak data of a self-selected sample."

And what is that makes Marilyn vos Savant so uniquely qualified to answer such questions? There is only one reason: she is listed in the Guinness Book of World Records as having the highest IQ ever recorded. Never mind that this record is based on a nonstandardized test put out by an obscure group known as Mega, supposedly the world's most selective organization of geniuses. Ignore the fact that test scores at the extreme ends of any distribution are notoriously unreliable.CS1 maint: ref=harv (link)
