 ISCT has attracted a great deal of attention and many critics. Much of this criticism has focused on hypernorms, the criteria for which are alleged to be ad hoc (Scherer 2015), ambiguous (Brenkert 2009), and incomplete (Mayer &amp; Cava 1995). Dunfee (2006b) collects and analyzes a decade worth of critical commentary on ISCT. For a more recent elaboration and defense of the approach, see Scholz, de los Reyes, and Smith (2019).
