In 1990s,
Libb Thims began collecting citations and references to various individuals with "purported IQs" in the nefarious ceiling genius range.
In 2008, Thims had a working Word document file of about 15 individuals with IQs cited in the 200 or above range, ranked from highest to lowest. [1]
In 2010, Thims, when the online version of the IQ:200+ genius listing was at the 25 person level, following the discovery of the "IQ:400" citation of
Adragon de Mello, as calculated by his over-zealous father, Thims began to engage into the task of re-ranking the world's geniuses. [1]
In 2011, Thims began to merge all of the geniuses, from the various historical
genius rankings, such as shown below, into one 400+ person "
genius IQs" listing, of all of the world's purported geniuses cited with or said to have an IQ of 140 or above:
● Terman IQ (1916)
● Cox IQ (1926)
● Platt IQ (1962)
● Guinness Book IQ (1970s to 1996)
● Walberg IQs (1981)
● Buzan IQ (1995)
→ Cox-Buzan IQ
→ Cox-Buzan-Platt IQ
● Simonton IQ [e.g. 40+ President IQs] (2006)
● Michael IQ [51 geniuses] (2008)
