In genius studies, genius rankings (chronology) refers to []


The following is a chronological listing of attempts to rank geniuses by IQ in the form of ranked lists; each grouped by number (#) of people in each list, or divided between number historical (#), historical candidates (C), or existive (E) people, if data is available:

Name # C E Date Maker
Terman IQ 1 1917 Lewis Terman; IQ ranking of Francis Galton as IQ 200 in youth.[1]
Termanites 1528 1921-28 a group of 1,528 children (856 males and 672 females) collected, between 1921 to 1928, by Lewis Terman, from around California, mean age 11 6 to 12 or so), labeled as "gifted" by Terman, and assigned with "genius IQs" (140+), mean IQ 151, 77 between 177 and 200.
Cox IQs[2] 300 1926 Catherine Cox, Lewis Terman, Maud Merrill; based on the top 300 minds, from the Cattell 1000, who existed between 1350 and 1850.
Mensa IQs 134K+ 1946 The first “high IQ society”, founded by Roland Berrill, a wealthy lawyer, and Lancelot Ware, a biochemistry student, the qualifications being that members had to score in the top 2% on an intelligence test; the specifics of this, however, are pretty sloppy, e.g. the first test was administered by Ware to Berrill, a "phrenologist", who declared Ware to be in the top 1% of people he had tested? The society began to fizzle in the 1950s, with 150 members, then revive later, having since churned out 134,000 paper IQs with IQ numbers of 132 and above.
Platt IQs[3] 12 1962 John Platt

Multi-Max Test 1974 Christopher Harding; mail-in ten-item multiple choice test, purported to yield an IQ of 200+ or a ceiling of 211.
Mega Test IQ[5] 1982 Ronald Hoeflin
