The authors of this study suggest that the harm-punishment link ('outcome bias') can be explained by the activation of different judgment processes depending on the outcome severity of an offense: (1) a rational model for mild outcomes in which punishment is necessarily linked to responsibility of the perpetrator; (2) a justification model for severe outcomes in which punishment and responsibility are linked only when assessment order allows the latter to rationalize the former. Participants (126 university students) considered an unintentional road accident with mild or severe outcomes and made judgments of responsibility, punishment, and perceived seriousness of the offense. The results support the authors' hypothesis. In the discussion, the authors suggest different motives of punishment (preventive or compensative justice) which explain why responsibility and punishment are not necessarily linked.The aim of this article is to examine the links between responsibility and punishment in the case of reprehensible actions leading to objective outcomes of greater or lesser severity. It attempts to demonstrate that according to the severity of the consequences of an offense, two types of judgment models are activated: a rational model in cases of mild outcomes and a justification model in cases of severe outcomes. In a rational model, the attribution of punishment to the perpetrator of an offense is the result of a series of decision stages (Fincham & Jaspars, 1980;Shaver, 1985;Weiner, 1995). In this model, the first stage is to verify the causal link between the offense and the noted effects. Second, the motive of the perpetrator is evaluated in order to establish his or her degree of responsibility. Finally, punishment is attributed according to the degree of responsibility. In this perspective, the a priori contributions of the perpetrator (causality and intentionality) should direct the judgment of responsibility and the attribution of punishment, and this evaluation should not be influenced by the a posteriori involuntary or unforeseen outcomes of the action.Certain influential factors cannot be well integrated into this rational schema, notably the 'outcome bias effect.' This bias, which different studies have confirmed (Burger
