This paper reviews research since 1970 on the relationship between accident liability and individual differences, focusing specifically on accidents at work. The history of research into accident liability and the methodological problems associated with the research are considered. The review goes on to examine work on the impact of personality factors, cognitive factors, and social factors on the likelihood of accident involvement at work. It is suggested that research into individual differences in accident liability should consider two possible routes to accident involvement via errors and/or violations. Although errors are predominantly associated with cognitive factors, violations have their origins in social psychological factors. The paper also considers the role of stress in mediating the personality-accident association. It is contended that individuals differ in their reactions to stress, so that although some respond by an increase in risk-taking behavior, the effect on others is to increase the likelihood of suboptimal performance in terms of information processing. Actual or potential applications of this research include the development of a more sophisticated model of individual differences in accident liability, which should be useful to organizations attempting to promote safety.
