In genius studies, true IQ (TR:5) (LH:1) (TL:6) refers to an IQ that is true (Cox, 1926); a term generally meant to differentiate between one's overall IQ, retrospectively speaking, and one's psychologist estimated youth (AI IQ) or young adult (AII IQ) IQs.
The following are quotes:
- “The true IQ of young Grotius may well have been above 200.”
- — Catherine Cox (1926), Early Mental Traits of Three Hundred Geniuses (pg. 162)
- “One rater (Merrill, 1925) has scored on the basis of the record of Goethe’s youth an IQ of 225. Goethe’s true IQ may in the history of mankind have been equaled in a few instances; one may well wonder whether it has ever been exceeded?”
