The omissions account offers structurally close explanations of the Knobe effect, the Butler problem, and the epistemic side-effect effect. Moreover, it predicts that the epistemic side-effect effect should be present not only in Knobe-type stories but also in Butler-type stories. Since the probability that the effect takes place is not greater than 1/6, the attribution of knowledge that it will take place is prima facie irrational. However, according to the omissions account, in the immoral situations, the knowledge claim can be read as a consequence-knowledge claim, which can be rationally accepted. I report the results of two studies, based on Nadelhoffer’s study of the Butler problem, where ascriptions of knowledge in Butler-type scenarios are investigated.
