ABSTRACT
Specialization is inevitable in scholarly work, but it carries with it penalties. Among these is a tendency toward divergence between the views of active workers in an area and those of nonspecialists. Such divergence can be particularly costly to both sides if a field is central or fundamental to other fields. The present chapter has been written in the belief that such a divergence has taken place in psychology with respect to measurement concepts, and the chapter’s main purpose is to orient the nonspecialist in measurement toward what is felt to be a contemporary view of measurement matters.
