Abstract
The research relating personality traits to industrial and traffic accidents is reviewed. All of the research is interpreted in terms of the "differential accident liability" concept, rather than the discredited "accident proneness" theory. The need to control for the confounding effects of age, experience, sex, and accident risk is discussed. It is concluded that the personality traits of extroversion, locus of control, impulsivity, aggression, social maladjustment, and some aspects of neurosis are related to the occurrence of accidents.
