 Examples of this approach include: Greene’s (Greene et al. 2001; Greene 2003: 848) fMRI investigations of moral judgment (criticized in Berker 2009), Horowitz’s (1998) attempt (see also Sunstein 2005) to explain certain intuitions taken to support the doctrine of doing and allowing using Kahneman and Tversky’s prospect theory (criticized in Kamm 1998 and van Roojen 1999), and aspects of Nichols and Knobe’s (2007) investigations of the role of affect on judgments regarding the compatibility of determinism and moral responsibility.
