According to the triangle model of responsibility, responsibility is a psychological adhesive that links an actor to a set of prescriptions for behavior and to relevant events. To test predictions from the model about the antecedents and consequences of responsibility, and also to test hypotheses about how the Protestant work ethic (PWE) is related to judgments of responsibility, participants made attributions about characters in achievement situations. PWE scores were associated with attributions of stronger links, greater personal responsibility, greater expected success, and more negative reactions to a possible failure. Further, PWE predicted responsibility even after statistically controlling for judgments of obligation, control, and clarity. The findings help to clarify why the PWE is associated with the tendency to make internal attributions for social ills such as unemployment.
