ABSTRACT
So it is clear that the practice of "calibration" is a very popular activity. Tt is therefore important that some investigation be made into the question of what it is and what difficulties one would face when attempting to use it when persuing an answer to a question that relies on quantitative measurement. In the following section we provide a definition and discuss what this definition means. This is followed hy a more extensive treatment of some of the issues. Section IV notes that those who regard themselves as calibrators are fierce proponents of it, and this ferocity can sometimes border upon intolerance for other approaches. yet there are many unresolved questions about whether calibration really is a satisfactory answer to the quest for quantitative information. We point out some of these and ask whether they have yet been satisfactorily answered within that literature. In some instances, where the answer is in the negative, the technology exists that should enable one to be able to go at least part of the way toward a resolution of these questions.
