What a Test Needs

What a Test Needs sorts the discriminating predictions of the Language of Stress by what testing them requires. The corpus has repeatedly stated that its predictions wait on a measure of archetype rigidity that does not exist. This document shows that statement is too broad. Of the ten discriminating predictions in the empirical predictions register, three can be run now with existing paradigms, two more need no reading of rigidity but wait on special populations, four need only an ordinal reading, and only the pathology prediction, with the strong form of one other, needs an instrument that compares people.

The document names three things the corpus has used without distinguishing: default rigidity, the tension an archetype engages at, set by substantiation history; engagement, whether a situation brings an archetype into play; and allocated rigidity, the departure from the default once an archetype is engaged. Because allocated rigidity overlaps with what precision-weighting accounts predict, the framework's discriminating tests lie where rigidity tracks stakes rather than confidence, and in default rigidity measured apart from attention.
