The attribution-of-blame model of judgments of injustice, which is the focus of this article, depicts judgments of injustice as blaming of an actor who is seen as responsible for the violation of the entitlement of somebody else without sufficient justification. Responsibility and blame are conceptualized in the model in accordance with Heider (1958) and Shaver (1985). The article briefly describes the background and the propositions of the model and its scope. Then it reports a series of four correlational and one experimental studies which tested the validity of the model. The findings lend support to the propositions that attributions of causality and intention and perceived lack of sufficient justification contribute to the perception of injustice beyond the mere perception that somebody's entitlement or deserving has been violated. However, no support was found for the assumption that perceived control of the respective agent contributes to the perception of injustice. The concluding section discusses the main findings of the studies and points to questions which should be pursued in future research in order to establish the range of validity of the proposed model of judgments of injustice.
