Descriptions of 14 hypothetical events were presented to 214 students (average age 15 years). The 14 descriptions were each written in two different ways: in the "commission" condition, each event described was an accident which resulted from an error which was committed by the target person; in the "omission" condition the target person was described as having failed to act in a way which could have prevented the accident. Subjects rated the likelihood of the outcome resulting from the target person's action, the severity of the outcome, and the responsibility of the target person. Regression analyses, treating likelihood and severity as independent variables with sex, smoking status and omission/commission as dummy variables, revealed an overall tendency for more responsibility to be attributed in the commission than the omission condition (although this depended on the specific event considered). There were also positive relationships between responsibility and both likelihood and severity. Males and cigarette smokers were generally found to attribute less responsibility than females and non-smokers. The implications for health education are discussed.
IntroductionMany attempts at persuasion, notably in the field of health and safety education, take the form of recommendations for prophylactic action. It is conceivable that one obstacle to the effectiveness of such communications may be that individuals are less likely to feel responsible for outcomes resulting from their failure to take appropriate preventive measures, than for outcomes resulting from hazards that they actively created. Thus, errors of omission may attract lower attributions of responsibility, other things being equal, than errors of commission. This distinction is also of interest if health educators wish to persuade people to be responsible not only for their own health, but also for that of people around them. If a policy of inactivity leads to less feeling of personal responsibility for an accident, then the natural tendency of "noninterference" will be difficult to counteract.In the large amount of psychological literature on attribution theory, relatively little attention has been directed to this variable of omission/commission. One exception is the study by Passer, Kelley and Michela (1978), but their main concern was not the assignment of responsibility. In an attempt to investigate whether the distinction was, in fact, relevant to responsibility attribution, Fincham and Jaspars (1980) reported two apparently conflicting results. Firstly, using stories where an actor either failed to observe a safety precaution or actually removed safety equipment to defray expenses, and an accident resulted, omission/commission was found to have no effect on the
