High school rank linked to survival throughout adulthood

A person's high school class rank is good for more than just getting into a prestigious college. A new study by a pair of University of Wisconsin-Madison researchers links class rank — a cumulative measure of responsible performance — with survival throughout adulthood. Class rank contributes to the development of mature behavior by late adolescence, the research shows. "The effect of class rank on survival was three times greater than that of IQ over the course of adult life, from 18 to 69," says Robert Hauser , Vilas Research Professor Sociology, emeritus, who authored the study with Alberto Palloni , Samuel Preston Professor of Sociology. "IQ is highly reliable but is based on a single test and reflects a narrow set of abilities." The association between IQ and longevity has been shown in many studies, but it has not been explained until now, Hauser says. Class rank is a behavioral measure based on a range of academic tasks — assignments, research papers, tests — over four years, in many courses with different teachers, thus requiring responsible, timely and consistent performance. It depends in part on academic ability, but it also reflects character, habit and personality, he says.
