title: Quality, quantity, and age: the careers of ten distinguished psychologists.
abstract: The longitudinal relationship between quality and quantity of productive output is examined over the careers of ten recipients of the Distinguished Scientific Contributions Award. Four alternative models of this relationship-expertise-acquisition, youthful-enthusiasm, peak-age, and constant-probability-of-success-yield distinctive predictions regarding 1) how the ratio of major contributions to total output changes as a career advances and 2) the developmental association between major and minor works over consecutive time periods. The quality of a publication was assessed by the citations it earned in the professional literature. The results endorsed the constant-probability-of-success model (both across and within careers). Not only does confirmation of this model provide support for Campbell's blind-variation-and-selective-retention theory of creative thought, but it additionally has important implications for understanding the role of age and chance in the careers of successful psychologists.
