an asymmetry in our judgments of whether an agent intentionally performed an action. It is "one of the first, most important, and most widely studied effects" in experimental philosophy. Knobe (2003a) asked people to suppose that the CEO of a corporation is presented with a proposal that would, as a side effect, affect the environment. In one version of the scenario, the effect on the environment will be negative (it will "harm" it), while in another version the effect on the environment will be positive (it will "help" it). In both cases, the CEO opts to pursue the policy and the effect does occur (the environment is harmed or helped by the policy). However, the CEO only adopts the program because he wants to raise profits; he does not care about the effect that the action will have on the environment. Although all features of the scenarios are held constant—except for whether the side effect on the environment will be positive or negative—a majority of people judge that the CEO intentionally hurt the environment in the one case, but did not intentionally help it in the other. Knobe ultimately argues that the effect is a reflection of a feature of the speakers' underlying concept of intentional action: broadly moral considerations affect whether we judge that an action is performed intentionally. However, his exact views have changed in response to further research. Experimental Jurisprudence Experimental jurisprudence is an emerging topic in experimental philosophy and legal scholarship that explores the nature of legal phenomena through psychological investigations of legal concepts. The field departs from traditional analytic legal philosophy in its ambition to elucidate common intuitions in a systematic fashion. Equally, unlike research in legal psychology, experimental jurisprudence emphasises the philosophical implications of its findings, notably, for questions about whether, how, and in what respects, the law's content is a matter of moral perspective. Experimental jurisprudence scholarship has argued that philosophers' appeals to the content of folk legal concepts ought to be tested empirically so that, the ‘big [philosophical] cost of rely[ing]... on… a concept that is distinct from that used by folk’, may be allocated correctly. Whereas some legal theorists have welcomed X-Jur's emergence, others have expressed reservations about the contributions it seeks to make. Predicting philosophical disagreement Research suggests that some fundamental philosophical intuitions are related to stable individual differences in personality. Although there are notable limits, philosophical intuitions and disagreements
