The original "IQ scale" devised by Lewis Terman (1916).[1]

In acronyms, IQ, aka “intelligence quotient”, refers to []

Overview

In 1916, Lewis Terman formulated the concept of "IQ". The IQ, in his model, is the estimated intelligence level of a person, based on the ratio of a person's "mental age" (i.e. mental ability, e.g. determined via test or accomplishment) and "actual age" (actual years old), multiplied by a hundred, in the original definition; a value on the natural number (1, 2, 3, etc) scale, where “100” is the intelligence of an average adult human, below "70" is feeble-mindedness, and "140" or above is genius or near genius level.[2]

Genius IQs

In Hmolpedia, if an existography of a person, e.g. Carl Clausewitz (1780-1831) (IQ:155|#605), is listed with an IQ estimate (e.g. 155) and top 1000 geniuses rank (e.g. 605), shown as (IQ:155|#605), at the edit point of that article, then the "IQ" shown, derives from a meta-analysis of the work of the individual, assimilated with all known previous IQ estimates (as listed on each individual's IQ column row on the top 1000 geniuses rankings table[s]).

  2. (a) Note 1: the original Terman method (1916) tended only to work reasonably well in respect to estimating or classifying IQs of young adults (age 4 to 16) in the lower range.
    (b) Note 2: the Terman method, in the higher IQ range, i.e. "genius level", tended to be inaccurate, in a long term prediction sense, when applied to humans in the youth age range (4 to 18); and only gave crude estimates of historical geniuses, based on "mental age" determinates, for youth aged (18 to 26) individuals, e.g. as attempted by Catherine Cox (1926).
    (c) Note 3: in the mid 20th century, IQs began to be estimated based on the tests, given to semi-large populations (e.g. 1,000+ individuals), wherein the test results were "normed" (to the mean score of the populous) and IQs were assigned to so-called "deviations" below or above the determined "norm", which more often than not, particularly in respect to the "ceiling IQs" tended to be the result of the personal bias of the "normer" or test designer.
    (d) Note 4: in the early 20th century, when "ratio IQs" (Terman method) and "deviation IQs" had resulted to make a cottage cheese industry of purported "genius IQs", the so-called "meta-analysis IQs" method began to become the standard for gauging the IQs of geniuses, in real time, based on retrospect, time-digested, analysis of that person's work, inclusive of the assimilation of all previous IQ estimates.
