 Cushman et al (2008) claim that their experimental data shows that moral appraisals affect classification of behaviour as doing or allowing. Cushman et al do not see this as presenting a special challenge for the doing/allowing distinction. They see these findings as adding to “a growing list of folk concepts influenced by moral appraisal, including causation and intentional action” concluding that: “the present finding favors the view that moral appraisal plays a pervasive role in shaping diverse cognitive representations across multiple domains” (Cushman et al 2008, 281).
