Heston (1966) and Heston and Denny (1968) suggested that their results may be explained in terms of a polygenetic disorder, in which a subcritical dose of the pathological genes produces or predisposes to disabilities other than schizophrenia "and perhaps in other combinations to especially adaptive personality traits" (Heston & Denny, 1968).
