In IQs, a genius IQ is intelligence quotient or integer number at or above 140 (Terman, 1916), the validity of the method used to discern IQ number being of prime importance (with the ratio IQ method being one of the least dependable), wherein strong weight is affixed to the conditional term “genius”, from the Latin gignere “to beget” (to produce), in the sense that one may have a strong aptitude, marked capacity, or heightened inclination in some area, but if one does not beget of esteemed respected intellectual note, one is not necessarily a genius and the IQ estimate may be a pseudo-estimate, false positive, or over-estimate. This factor is taken into account in the following weighted meta-analysis genius rankings (413+ geniuses), wherein left column IQs are considered true IQs.
