In genius studies, ID, aka “Intellectual Density”, is the ratio of the "real IQ", of a person, to the "age" of the person, at the point when the IQ was determined; which thus gives a gauge or an indicator as to the "density of work" produced by the given genius, on average, per year or decade of existence. If the person is historical, than the age is their years of existence, divided by their retrospect real IQ.
In 2014, the abbreviation key (RE:#) was introduced to give a quick indication of a given person’s age or “reaction extent”, thereby facilitating the differentiation of high “magnitude geniuses”, such as Maxwell (RE:48) or Lavoisier (RE:50), who produced great work in a few number of decades (30s, 40s, or early 50s), as compared to aged geniuses, such as Goethe (RE:82) or Adam (RE:80), who were still producing great genius work into their 70s and 80s.
In the Hmolpedia 2020 “genius” article, the section “magnitude geniuses” gave an overview of the concept of geniuses with great density or magnitude per decade; citing the examples of Lavoisier, who was guillotined (age 50), Maxwell who died the same year as his mother by the same disease (age 48), Majorana who “mysteriously disappeared” (drowned himself) (age 32), and Ramanujan who died of malnutrition (age 32) as examples of people who “produced a great density of genius work in a very compacted number of years”.
On 26 Oct 2020, while making the new MediaWiki-based top 1000 geniuses table, and while cleaning obsolete abbreviation keys, such as “like ranking” (LR:#), which had become inoperational in the old wiki, and the “reaction extent” (RE:#), which become defunct in the sense that it was only used in a few dozen cases and really did not provide for a ranking comparison, the idea of dividing the person’s "real IQ" () by their "age" (A), reaction extent (RE), or "years of existence", came to mind, as a way to replace and upgrade the old RE placeholder, employed as it’s own column showing the “IQ density” (IQD) of each person; formulaically:
This IDQ value, thus thereby working to differentiate the "Maxwells (IQD:4.27|A:48) and the Lavoisiers (IQD:3.60|A:50)" from the "Newtons (IQD:2.44|A:84) and the Adams (IQD:2.44|A:80)", in respect to how much “density” of genius a person completes in their overall existence.
On 28 Apr 66AE, Thims shortened IQD, which was showing up in existographies with a "D" as the acronym, e.g. Baron Holbach (D:2.92|A:62), to "ID", Baron Holbach (ID:2.92|Y:62), thereby making the abbreviation immediately recognizable, as short for "intellectual density" of a person in a given "being state". Thims also switched A (age) to Y (years), meaning the given individual had that IQ at that many years of existence.
Majorana | Example
To go through one example, according to the opinion of Fermi, Ettore Majorana was an "above first rate" genius, comparable to Newton or Galileo:
- “There are several categories of scientists in the world; those of second or third rank do their best but never get very far. Then there is the first rank, those who make important discoveries, fundamental to scientific progress. But then there are the geniuses, like Galileo and Newton. Majorana was one of these.”
- — Enrico Fermi (1938), Publication
Yet, differentiating the three, Majorana, according to Fermi, did in three decades, what Newton and Galileo did in eight decades. The IQD value thus gives a way to differentiate geniuses in this respect. he following, to exemplify, is a selection of geniuses from the top 200 range of the top 1000 geniuses table (on 26 Oct 2020), with which one can click on the IQD column and see geniuses ranked by "density", Majoana ranked #2 in density, and Galileo and Newton ranked lower:
=180, 210, 240
||Alexander the Great
The IQD method of gauging geniuses by density, to note, only produces reliable results (a) after the person has "ceased to exist", (b) the person had reached or attained the "genius level" (IQ:140+) status, per general or established consensus, and (c) after their "real IQ" has been estimated.
In other word, in 2020, the average age of "death" (cessation) is 78 and the average IQ is 100, the the average IQD (100/78) for such a person is "1.28" meaning that such a person effect an mean IQ density gain of 1.28 IQ point gain per year over the course of their existence. If, comparatively, we calculate the IQD of someone who ceases to exist at age 21 with an average IQ of 100, we get a value of "4.76", which puts said hypothetical person in the Maxwell, Turing, Leopardi genius density range, which does not compute. This is not to mention children, adolescents, and young adults, who may have had their IQ ratio estimated at 200 but only be age 10, which yields and IQD of 20.00, which again does not compute or make sense. Hence, the ABC criterion, defined above.
