Positive ecological, group-level associations of Lynn & Vanhanen’s 2002 national intelligence estimates with the suicide rates of men & women across 85 countries & with the suicide rates of the male, female, & total elderly population across 48 Eurasian countries reported recently is extended by the finding that this ecological association was notedly better accounted for by exponential fitting than by linear fitting. This evidence implies that the effect of a shift in the national intelligence quotient on the suicide rate is proportional, not absolute. (5 refs.)
